Answer 5

drift

Question 6

The amount of drift that an aircraft experiences depends upon 3 factors …..

Answer 6

1. The strength of the wind

3. The TAS of the aircraft

Question 7

If a faster aircraft and a slower aircraft hold the same heading in the same wind …..

the wind will move both aircraft the same distance sideways but the faster aircraft will travel further forward and experience a smaller angle of drift because of the distance in relation to the starting point
