BAK - Principles of Flight (Wake and Turbulence) Flashcards
What is the turbulence generated from large aircraft as a by-product of lift referred to?
Wake turbulence
What is the strong turbulent downdraft generated by the blades of a hovering helicopter referred to?
Rotor downwash
What area below a hovering helicopter should be avoided by pilots of light aircraft?
Within a radius of 3x times the rotor diameter
True of False - thrust stream turbulence or jet blast can damage the structure of a light aircraft?
True
What is the primary control hazard for light aircraft as a result of vortex encounter?
Induced roll
True or False - the strongest vortices are generated by large, heavy, ‘clean’ and slow aircraft shortly after take-off?
True
True or False - The greater the lift being produced by the generating aircraft, the stronger the wintip vortices, ie: wake turbulence
True
When taking off behind a large departing aircraft on the same runway, should a smaller aircraft lift off prior/ just past the larger aircraft’s rotation point and should they then climb above/below its climb path until turning clear of the wake?
The smaller aircraft should lift off prior to the larger aircraft’s rotation point and then climb above the larger aircraft’s climb path until clear to turn clear of of their wake
When landing behind a larger aircraft which has just landed at the same runway, should a smaller aircraft stay above/below the larger aircraft’s final approach path and should they then land in front of/ beyond the larger aircraft’s touchdown point?
The smaller aircraft should stay above the larger aircraft’s final approach path and then beyond the larger aircraft’s touchdown point
Do vortices tend to remain strong and within the touch down or take-off areas for a longer period of time in windy or calm conditions?
Calm conditions
