Operational procedures

It is at least an invisible danger - and that makes it extra dangerous.

Although we can get whirled around when

we are in the air, it is not so dangerous if
we are at a good altitude so that we can

regain control of the aircraft.

We will now look at different situations in

connection with take-off and landing.

6.9.2.2 Edge vortices after taking off aircraft

The risk is greatest during take-off and landing and when flying close to airports

with heavy aircraft traffic.

A taking off aircraft produces edge vortices from A.

A landing aircraft produces edge vortices until it places the nose wheel on the

runway at point B.

This is the knowledge we use when we must take off and land after aircraft that

produce edge vortices.

When we are approaching after a heavy aircraft, we must make a higher

approach and land further into the runway.

We must expect that the edge vortices will be carried by the wind to the right.
