\"Wake<\/a>A short while ago, I published an item about the disastrous effects of taking off too soon behind a heavier aircraft – ‘The dangers of wake turbulence<\/a>‘<\/p>\n

In that article, the advice was simple – bide your time and wait at least 2 minutes before taking off after a heavier aircraft. But here’s a bit more detailed advice from CFI Bob Nardiello, who has\u00a0over 12,000 hours of flight experience (including 8,000+ hours of instruction). Bob was\u00a02004\u00a0Flight Instructor of the Year\u00a0and 2006\u00a0FAA Safety Counselor of the Year.<\/p>\n

His advice on wake turbulence take-offs:<\/p>\n

“Vortices tend to move outward from the aircraft. So if you are behind a departing aircraft, the vortex from the right wing will tend to move to the right and the vortex from the left wing will tend to move to the left – in nil\u00a0wind conditions.<\/p>\n

If there is\u00a0a crosswind, the wind will influence the movement of the vortices. A crosswind of about 3 knots will hold the upwind vortex pretty much in place on\u00a0the runway where it was created, while the downwind vortex will move rapidly away from the runway.<\/p>\n

\"Wake<\/a>Crosswinds greater than about\u00a05 knots will tend to break up the vortices fairly quickly. So stronger crosswinds are good things, as far as vortices are concerned\u00a0–\u00a0we want the vortices to break up and decay as soon as possible. So light crosswinds around 3 knots and under require maximum caution.<\/p>\n

We also need to note the lift-off point of the previous\u00a0aircraft. That point is where the vortices will be developed. From that point on, there will be vortices off the wings of that departing aircraft. So it’s important that your take-off\u00a0point occurs before the take-off\u00a0point of the preceding aircraft. You\u00a0DO NOT\u00a0want to be taking off into\u00a0the vortices of the preceding aircraft!<\/p>\n

You need\u00a0to climb on\u00a0the upwind side of the departing aircraft to avoid\u00a0the crosswind effect of\u00a0the vortices. So if the crosswind will move the vortices to the left, your departure path should be to the right to avoid those vortices.”<\/p>\n

So next time you’re taking off behind another aircraft, particularly a heavier one:
\n– WAIT!
\n– lift off well before the take-off point of the preceding aircraft; if you can’t be sure to do\u00a0this, WAIT!
\n– when you do take-off try to track to the upwind side of the earlier aircraft’s track.<\/p>\n

Safe flying!<\/p>\n
