New Aeroprakt A32 announced

A32Aeroprakt has announced the release of a brand new aircraft in its range – the A32.

The 600 kgs gross weight LSA-compliant 2-seat A32 will be built in limited numbers alongside the popular A22LS and A22L2 ‘Foxbat’ aircraft.

Bearing a strong family resemblance to the A22, the new aircraft has been in development for over three years, with particular attention to the aerodynamics of the airframe and ergonomics in the cabin. As a result, the cabin is spacious and quiet and the aircraft will happily cruise in the 110-115 knots range, without affecting its slow speed docile handling characteristics.

Full details will soon be on the Foxbat Australia website (which is being significantly re-designed) and I’m expecting an A32 demonstrator to arrive in Australia late in June. There will be a formal launch of the new aircraft in Australia, probably at Tyabb Airport, during July.

First customer deliveries of the A32 are expected later this year. Prices have not been finalised but will probably be around A$110,000 fly-away, including registration and GST.

New Aeroprakt Aircraft?

Aeroprakt A03 32 pixelsOne of my spies has sent me this somewhat blurry photo – the aircraft looks a bit like an A22 Foxbat but even through the blur it’s possible to see some marked differences – no little tailwheel, all-flying tailplane, different rear fuselage, windshield level with the top surface of the wing and maybe a different engine cowling…more to come when I have better photos.

5 best books about flying

A few people commented on my reference to the Cannibal Queen book in a recent post about my favourite aeroplanes and asked what other books about flying I like. Apart from my (very) early years reading ‘Biggles’ books, I have read only a few really good books about flying. Here is a list of five of the best, in no particular order. Having already mentioned the Cannibal Queen, although it is a favourite, I have not included it in the list.

The Wild Blue Yonder – Book of Aviation.
Wild Blue YonderThis is a non-fictional account of aviation in the 20th century, originally published in 1997. Allowing for the almost 20 years since its publication, this is an still an engrossing account of flying and aeroplanes – from the early pioneers like Saint-Exupéry and Markham and their lonely solo flights through to breaking the sound barrier with Chuck Yeager and many before, after and in between. Even including Biggles! It’s not a cheap book at over A$75 (if you can find a new one) but is completely absorbing and a marvellous compilation which you can dip into time and again and still find something new. Searching the usual book websites will turn up secondhand copies of varying qualities from as little as A$5 but make sure you know who you’re ordering from before leaping to buy!


Wind, Sand and Stars
by Antoine de Saint-Exupéry
Wind sand stars
Against a backdrop of flying the mail routes in the Sahara and South American Andes, Saint-Exupéry writes of friendship, death and heroism. The book describes his exploits and, in particular, his near fatal accident in the Sahara Desert, when he and his navigator/engineer almost died of thirst and dehydration after surviving the initial crash. The book was originally published in French in 1939 but was soon translated into English – and, shortly afterwards, significantly changed, as the author felt some of the content was not appropriate for its USA readers. In French, the book was titled ‘Terre des hommes’ (‘Land of men’) with the English ‘Wind, Sand and Stars’ suggested by the translator. Although the translation is many years old, the book is still a good read, telling of times when aviation was still an extremely risky business.


Zero 3 Bravo
by Mariana Gosnell
Zero three bravoAnother non-fictional account of flying across the USA in a small aeroplane – this time a 1950 Luscombe Silvaire (registered Zero 3 Bravo of the title), which, to the uninitiated, is a 2-seat metal high wing aircraft with a cruise speed of about 85 knots. This is the true story of 60 years-old Mariana Gosnell, who set out in the early 1990’s for a three-month trip from New York across the USA to the west coast and then back again. It recounts her experiences of the people she met along the way and is well-illustrated with photos she took. It’s one of those books that are very enjoyable and easy to read – the only downside (if you’d call it that) is that it will start you dreaming of (even planning) your own trip! Highly recommended.

The Spirit of St Louis by Charles Lindbergh
Spirit of St LouisI suppose no collection of aviation books would be complete without the amazing tale of the first solo flight across the Atlantic Ocean in a single-engined aeroplane. This is the book, written by Lindbergh, which was published many years – in fact over 25 years – after his epic flight. It won the Pulitzer Prize in 1954, the year after its publication. Apart from covering the flight itself, the book also describes in detail the preparation and planning for the flight and, in particular, overcoming the almost insurmountable problem of building an aircraft with enough speed, yet still able to carry a pilot and enough fuel for the journey. In the end, the aeroplane was filled with over 450 US gallons of fuel (that’s over 1,700 litres) and just about managed to take off at almost half a ton overweight – that’s a lot for a small single engine plane. How Lindbergh stayed awake during his long solitary night flight towards Europe is recounted so well, you could almost be there yourself. New copies of the book can still be found with a little digging – it was reprinted at least in 2003. Here’s a link to s short video, with subtitled commentary on the take off: ‘Well then I might as well go’

Propellerhead by Antony Woodhead
PropellerheadLast but not least is this funny, charming, part fiction, part autobiographical tale, of a young man and his friend (only one of whom knew how to fly) who decide that owning an aircraft will make them chick magnets (his words, not mine). So they set out to buy a microlight/ultralight in the form of a tube, fabric and wire ‘Thruster’ aircraft – described as a flying lawn mower with two plastic chairs. Along the way, he learns about and makes lists of all the various microlighting paraphernalia and in particular, falls in love – not with a lovely young damsel – but with being up in the air and the sheer joy of flight. Captivatingly amateur in its approach, this is at the root of the book’s appeal, along with all the views of the world common to young men. In a way, it’s a ‘coming of age’ story which is well-told and, in parts, hilarious along the way.

Happy reading!

My top 10 aeroplanes – part 1

I’m sometimes asked: ‘If money was no object, what aeroplane would you buy?’ Realistically and unfortunately, money is an obstacle to both buying and running an aeroplane, so I’d have to rule out things like the impressive 4-seat Cirrus and lovely old warbirds like P51 Mustangs and Harvards. And anyway, even if I could afford them, I likely wouldn’t be buying one because there are plenty of other aeroplanes which tick my boxes, get my blood flowing and cost considerably less. Mostly.

The following list (part 1) is in no particular preference order and if you asked me a year ago or in a year’s time, I’d probably give a different answer.

Vans RV-7

Vans RV-7

Two-seater with a high cruise speed – Vans RV-7
The Vans range of kit aircraft is now almost legendary – not only for its sheer production numbers but also for the delightful handling characteristics of every single aircraft in the range. For me, the RV-7 is the pick of the bunch, with two comfortable, side-by-side seats and a true cruise speed in the 160-180 knots range. In standard configuration, it will carry a reasonable amount of fuel and, if fitted with an auto-pilot and auxiliary fuel tanks, it really is possible to cross Australia in a day. The only drawback is that you either have to build it yourself or wait for someone to sell you a ready-built one. If you’re buying ready-built, look out for shonky metal work, which may be evidence of haste and cost-cutting in areas hidden from view.

 

Aerolite 103

Aerolite 103

Open air single seater – Aerolite 103
Right at the other end of the scale is this nice little single seat ultralight/Part 103 aircraft from Aerolite – now also available in Europe as the Aerolite 120 (a reference to the kilos empty weight limit of the aircraft). I have always been a fan of open air ultralights, in spite of an early nasty experience with an infamous UK-built aircraft called the Southern Aero Sports Scorpion, which gained the dubious honour of becoming the first ever ultralight to be grounded by the UK CAA due to a series of unexplained in-flight structural failures. In complete contrast, the Aerolite design is tried and trusted and many of them have been sold world-wide. Unfortunately these factory built aircraft cannot legally be registered in Australia or I would probably get one. They are inexpensive, great fun (on a calm day) and can be folded to fit in your garage or hangar.

 

J-3 Cub

J-3 Cub

Antique – Piper J3 Cub
This is a perennial favourite, with many thousands built in the 1940’s, 1950’s and 1960’s. Although flown from the back seat, the J3 set the standard for easy-to-fly taildraggers and many a (bush) pilot learned to fly in one. A nicely restored version can fetch several tens of thousands of dollars but a good honest aircraft with plenty of engine time remaining can be found for under $30,000. One of my favourite videos is Lainey’s First Flight of a youngster of about the same age as my grandchildren enjoying a flight with her Dad in a J3. Click here for the excellent Wikipedia entry for the Cub.

 

Cessna 180

Cessna 180

Load carrier – Cessna 180/185
The Cessna 180/185 truly has become a legend in its own time. Legendary for its ability to lift heavy loads out of short airstrips and cruise at a reasonable speed. Although still subject to all the potentially expensive SIDS requirements, the 180/185 series are amazingly rugged aircraft and have accumulated a vast range of TSO’d options and modifications from STOL wing kits (which change the wing aero profile and add ‘fences’) to strengthened landing gear and brakes. Recently a customer arrived at Tyabb in his 185 to collect some parts to repair a Foxbat – click here to see a photo of what he fitted inside the aircraft.

 

Boeing Stearman

Boeing Stearman

Biplane – Boeing Stearman
A few years ago, my father-in-law gave me a book called ‘The Cannibal Queen’. This is a non-fictional story, by thriller writer Stephen Coonts, recounting his 1991 exploits in the yellow Boeing Stearman of the title. He set off to land the aircraft at least once in every one of the 48 mainland states of America. He tells of FBOs (Fixed Base Operators) in the middle of nowhere providing him with a pick-up truck to get into town, in exchange for buying a tank full of fuel. He describes each and every one of his landings, some of which were ‘not so good’ and some of which were ‘terrible’. He says the Stearman always had control and it was down to a whim whether she (the Cannibal Queen) was in a good mood and would let him down gently. I love the look of the Stearman – when you get up to it, it is a big aircraft. In lower horse-power models, it was used as a primary trainer for the military. The higher power versions – 450 hp and up – make excellent aerobatic aircraft, although they are somewhat more difficult to fly. Some people (I think wrongly) compare the Stearman much more favourably with the UK Tiger Moth which, they allege, was not a good trainer. Whatever, I love the sound of those big lazy radial engines, even if they do gulp the fuel.

Choosing a Light Sport Aircraft (LSA) – 5 – which one is best?

PilotWhen customers ask me about the Foxbat, the question I hear most is not ‘How fast?’, ‘How far?’ or ‘How much?’ but ‘What makes your Foxbat better than any other (or sometimes a specific) recreational/light sport aircraft?’ While I understand the reason for asking the question, it’s a bit like asking which is better: a pick-up/ute, a sports car or a sedan.

When I learned to fly – all those years ago – an aeroplane was pretty much an aeroplane – two wings (even back then, biplanes were often antiques), an engine at the front (anywhere else was considered a bit weird), and two seats, unless you were very very rich and could afford four. The Cessna 150 was the two seater of choice and the Cessna 172 the 4-seat family sedan of the air. And their Piper equivalents. There were specialist aerobatic aircraft and crop spraying aircraft but mostly the rest were all in much the same boat. If you don’t mind me mixing my mediums.

Over the intervening years, ultralights and light sport aircraft have come along and diversified the market beyond all expectation. I remember when you could get just plain salted, cheese & onion, or salt & vinegar crisps (chips to our USA friends). Now look at the amazing choice available. Same goes for yoghurt. Same goes for aeroplanes….

So what’s the ‘best’ aeroplane for you?

Evening flightMany people just want an aircraft to fly for leisure – mostly at weekends, sometimes on summer mornings/evenings and very occasionally for a longer trip to a fly-in or some similar event. They want something that’s at least pleasant, even beautiful, to their eyes and fits their wallet. A lot of first-time buyers are relatively low-time pilots, so the handling characteristics and feel of the aircraft are often less important to them than looks, cruise speed or comfort. Or, occasionally, short take off and landing performance. Realistically, their choice is perhaps the simplest – does it look good (to them) and can they afford it?

It’s when you start selecting essential qualities that the decision becomes more difficult.

Flying tractorFor example – a farmer/landowner wants a strong landing gear and good safe slow speed handling so they can take-off and land in small spaces on unprepared paddocks. Outright top speed is likely not a key decider. The aircraft needs to be robust and reliable, because it’s going to be used a lot, and down-time is potentially lost money. And it probably needs to be easy and safe to fly near to the ground. And quick and easy to fix if it breaks down or gets broken.

These same characteristics also apply in large measure to flying school aircraft – ideally they need to be easy to fly and land, with robust landing gear. That way, the chances of an incident that results in damage are minimised. If the aircraft does get bent, they need it fixed quickly or it’s losing money rapidly, so parts availability is crucial.

WookieAnother example: if you are a big person, you’ll need to be able to fit into the cabin – it’s a good job the Millennium Falcon had a roomy flight deck! And if you are heavy, you’ll need an aircraft that can carry you, a reasonable amount of fuel and probably a passenger. There are light sport aircraft on the market that can legally carry less than 200 kilos – that’s everything: pilot, passenger, baggage and fuel. Put two 90 kilo people on board, no bags, and that leaves you 20 kilos for fuel – about 28 litres, which will last about 75 minutes.

fast-spacecraftThen there are the speed freaks – as long as they can say it goes faster than yours, it’s the one for them. But to go fast in an aeroplane demands compromises – smaller cabins, so there’s less drag; landings are potentially faster, longer and trickier; and the airframe has to be stronger (read: heavier) to cope with rough air at higher speeds…reducing the load carrying capacity. As one famous old American flying ace commented: ‘Unless you’re going at least 50% faster than the others, after a very short time you won’t notice any difference’. And next month someone else will buy one just a bit faster.

By now, you’re probably starting to realise (if you hadn’t already) that all aircraft are a compromise and are designed according to a set of requirements decided by the manufacturer. As with all types of vehicle, there’s no such thing as ‘all things to all people’.

EindeckerSo an important thing to think about, when deciding which aircraft, is what’s best for you – and be realistic! How often will you really fly it? Will you usually take a passenger with you or fly alone? How far will you really go on a typical flight? Are you really going to fly round Australia in it, one day? Will the aircraft really carry the weight you need it to? Why is speed important? Is getting there 10 minutes quicker, probably using more fuel, really that important?

There are no simple answers. For me – and I emphasise me – the A22 Foxbat does what I want: takes off and lands slowly in short distances, has a fantastic view out, uses the ever reliable Rotax 912 engine and is safe and easy to fly. It has a big roomy cabin and legally carries a big load. It’s not the fastest flier in its class but I can live with getting there a few minutes later, which is outweighed (for me) by all the other pro’s.

Choosing a Light Sport Aircraft (LSA) – 3 – primary safety

Safety 01Probably the single most important factor in choosing an aircraft is safety – and it’s usually the most overlooked and under-rated aspect of an LSA.

I remember (old geezer that I am) when motor car companies said that ‘safety doesn’t sell cars’ and they concentrated on looks, acceleration, top speed, road holding, even comfort. Volvo was just about the only company selling safety in their vehicles and as a result gained a reputation as a safety conscious, old people’s car, which has taken years to shake off. If they ever have.

Nowadays, all car manufacturers – not just Volvo – tell you how crash-resistant their vehicles are, how many airbags they have, how anti-skid the brakes and steering are. They have things like traction control and other electronic devices to get you out of the trouble your excess speed or other stupid behaviour just got you into.

So, what about Light Sport Aircraft safety? There are two main aspects to consider: primary and secondary safety. ‘Primary’ refers to the way the aircraft is designed to reduce the likelihood of an incident or accident happening in the first place. ‘Secondary’ refers to the aspects of the aircraft which reduce the effects of  an incident or accident.

Aircraft primary safety can broadly be grouped into ground handling, take-off, stalling & spinning, and landing.

Ergonomics 02But first – ergonomics
Ergonomics are a good place to start, because if they are wrong for you, it doesn’t really matter about the rest. Start with something completely counter-intuitive: how quick and easy is it to exit in an emergency like an engine fire? How easy is it to release the safety belt, open the door and hop out? Think: can I comfortably sit here for 2-3 hours and fly the aircraft? Are you cramped with a passenger on board? Can you still easily operate the controls to their limits with someone else next to you? If reaching a control, adjusting an instrument or even just looking outside the aircraft are a chore, these activities will soon be minimised and put in the ‘can’t be bothered’ basket and as a result, your safety will be compromised.

On the ground
Next, on the ground: how well does the aircraft steer and brake? It is well known that taildraggers are trickier to steer and brake than nose-draggers. But less well known is that some nose wheel aircraft can be a bit of a handful too.

Whereas most taildraggers steer via feet-operated differential main wheel brakes with castering (and sometimes steerable) tailwheels, most modern nose wheel aircraft steer more directly through rudder pedal couplings to the nose leg. This has the advantage of more directional control when the wheel is on the ground. But a potential disadvantage when landing in crosswinds, as the nose wheel may not be pointing in your direction of travel when it touches down. Castering nose wheelThis can lead to bent or even collapsed nose legs. So some aircraft designers have stuck with (or even reverted to) castering nose wheels, steered by main wheel differential braking – either by feet or hands. This gives slightly trickier ground handling especially when it’s windy but reduces the chances of bent gear when landing cross wind. Castering nose wheels usually have a smaller turning circle than direct steering, a particular advantage when back-tracking and turning on narrow runways. There are advocates of both systems – try both and take your choice.

In the air
First, take-off. When applying power for take-off, all single engined aircraft pull to one side due to the combined effects of gyroscopic forces from the engine and propeller and sometimes the spiralling airflow over the tail. Some aircraft have the engine offset so that it points to one side or the other to help minimise the pull – which can look a bit odd from some angles. Correcting the pull should be easy, through application of opposite rudder. However, some aircraft have a much stronger tendency to swing than others. Check out this effect and make sure it is controllable – particularly (eg) if the engine pulls to the left and the wind is blowing from the left, both of which will conspire to turn you off the runway if you don’t take prompt corrective action.

Stalling

stallingWhat about the stalling characteristics? Most LSAs stall very benignly, the nose goes down gently and rarely does a wing drop – something caused when one wing loses lift before the other, for a variety of reasons, but usually because the aircraft is being flown out of balance, with the slip ball not centred. Stalling with a wing drop is most dangerous when making that low-level turn onto final approach before landing. There are a few aircraft which can bite unexpectedly when stalled – if you are an experienced pilot and aware of what’s happening, prompt action can save you. But if the characteristic is particularly vicious and/or you are a low-time pilot, the chances are you won’t survive a finals turn stall with a wing drop. Check this aspect of the aircraft with someone familiar with the type and maybe even ask an instructor to take you up high and try stalling in turns.

Now look at the relationship between stall speed and flap limiting speed. I know of at least one LSA where the stall speed without flap is less than 10 knots below the flap limiting speed. Think about it: you’re coming in to land and you can’t lower flap (eg) until 55 knots. Your stall speed without flap is 45 knots. So you don’t have much margin of speed in which to get the flaps down. Personally, I’d want an aircraft where the ‘clean’ stall speed is at least 40-50 knots below the flap limiting speed.

Spinning
Spinning is really just a stall with maintained wing drop. When I learned to fly, spin recovery was on the syllabus. The aircraft I started to learn on was a Piper Colt, which was difficult to spin – the best you could get out of it was really a spiral dive. To make sure we knew how to recover properly from a spin, we were all taken up in a Beagle Terrier – an excitable little aircraft whose bite was far worse than its bark! Nowadays you aren’t allowed intentionally to spin an LSA and spin recovery training has been replaced with ‘incipient spin’ recognition. Because unintentional spins almost always happen when the pilot’s attention is absorbed with something else, I personally believe spin recovery should be taught as part of basic training, even though most (but not all) LSAs are spin-resistant. At least you will learn instinctively to apply opposite rudder to stop the spin and then raise the nose and apply power. Check out how easy it is to spin your preferred LSA – the manufacturer is required to have carried out spin testing as part of the ASTM certification programme.

Landing
Approach speeds vary a lot with LSAs. Some require at least 65-70 knots down final, others as little as 40 knots. The faster the landing speed, the more wear and tear on the aircraft and the faster things happen if they go wrong. So in the same way you wouldn’t get into a Ferrari to learn to drive, so you shouldn’t get into a fast aircraft to learn to fly! Build your skills in slower gentler aircraft before taking on the trickier ones. And anyway, you might find you like going slow!

LandingWhen assessing the aircraft’s landing characteristics, it’s important to check the correct approach speed – take it up to 3,000 feet AGL and try a few stalls. Note the indicated stall speed. Your approach speed for a low inertia aircraft like an LSA should be around 150% of that speed – much faster and you’ll float all the way down the runway; much slower and you risk a low-level stall. For example, the Foxbat indicated stall speed in landing configuration at maximum weight is in the low 30’s knots; approach speed therefore should ideally be around 50 knots. The factory manual actually says 49 knots. With one person and half fuel, stall in the Foxbat is around 26-27 knots – so approach speed can safely be reduced to 40-45 knots.

When landing, also look out for elevator authority. At least one LSA ‘runs out’ of elevator at landing speeds only slightly slower than its pilot manual advises. This can lead, at best, to a heavy landing; at worst to broken landing gear, because you can’t arrest the downward momentum without applying quite a lot of power. Usually, the reason the elevator loses its bite at slower speeds is because its travel has been limited so as to minimise the effects of inadvertent stalls – the downside is the loss of elevator authority when landing slowly.

In summary
Ground handling and flight characteristics of all aircraft are a compromise, based on what the designer/manufacturer is trying to achieve. Undoubtedly, current LSAs are among the safest handling aircraft available – after all, they mostly incorporate the latest computer-aided design techniques, they stall gently and are spin-resistant. But there are still a few mongrels among them.

Opinion about ‘pleasant’ and ‘unpleasant’ handling aircraft will always be divided so don’t rely on someone else’s personal preferences. Out there is an aircraft for you – fly as many different types as you can, if possible for at least an hour each. That way, you’ll begin to get the feel of the primary safety characteristics you like.

Next – secondary safety.
