Wake Turbulence Flashcards
PSTAR
Avoiding wake turbulence is
(1) the sole responsibility of ATC.
(2) the responsibility of the pilot, only when advised by ATC of the possibility of wake turbulence.
(3) a responsibility shared by both the pilot and ATC.
(4) the sole responsibility of the pilot.
(4) the sole responsibility of the pilot.
Hazardous wake turbulence caused by aircraft in still air
(1) dissipates immediately.
(2) dissipates rapidly.
(3) may persist for 5 minutes or more.
(4) persists indefinitely.
(3) may persist for 5 minutes or more.
Which response is most correct with respect to wake turbulence?
(1) Wing tip vortices are carried by the ambient wind.
(2) Wing tip vortices have a circular and downward motion.
(3) Wake turbulence exists behind all aeroplanes and helicopters in flight.
(4) All of the above are correct.
(4) All of the above are correct.
The wing tip vortices generated by a heavy aeroplane can cause a lighter aircraft encountering them to
(1) go out of control.
(2) continue descent even when maximum power is applied.
(3) sustain structural damage.
(4) experience any of the above situations.
(4) experience any of the above situations.
During the two minutes after the passage of a heavy aeroplane in cruising flight, hazardous wing tip vortices will
(1) dissipate completely.
(2) dissipate rapidly.
(3) dissipate very slowly.
(4) remain at cruising altitude.
(3) dissipate very slowly.
The pilot of a light aircraft on final approach close behind a heavier aircraft should plan the approach to land
(1) beyond the touchdown point of the other aircraft.
(2) prior to the touchdown point of the other aircraft.
(3) at the touchdown point of the other aircraft.
(4) to the right or left of the touchdown point of the other aircraft.
(1) beyond the touchdown point of the other aircraft.
Wake turbulence is produced by
(1) heavy aeroplanes only, regardless of their speed.
(2) turbo-jet powered aircraft only.
(3) fast moving aeroplanes only, regardless of their weight.
(4) all fixed and rotary wing aircraft.
(4) all fixed and rotary wing aircraft.
Wake turbulence caused by a departing large aeroplane begins
(1) before rotation.
(2) with rotation.
(3) after becoming airborne.
(4) with full power application.
(2) with rotation.
Wake turbulence caused by a departing aeroplane is most severe immediately
(1) before rotation.
(2) following take-off.
(3) above its flight path.
(4) following full power application.
(2) following take-off.
Which statement concerning wing tip vortices is false?
(1) Vortices normally settle below and behind the aircraft.
(2) With a light crosswind, one vortex can remain stationary over the ground for some time.
(3) Lateral movement of vortices, even in a no wind condition, may place a vortex core over a parallel runway.
(4) Vortices are caused directly by ‘jet wash’.
(4) Vortices are caused directly by ‘jet wash’.
Wake turbulence will be greatest when generated by an aeroplane which is
(1) heavy, landing configuration and slow speed.
(2) heavy, clean configuration and slow speed.
(3) light, clean configuration and high speed.
(4) heavy, take-off configuration and slow speed.
(2) heavy, clean configuration and slow speed.
A helicopter in forward flight produces hazardous vortices
(1) which rise above the helicopter.
(2) similar to wing tip vortices.
(3) which remains at the same level as the helicopter.
(4) ahead of the helicopter.
(2) similar to wing tip vortices.
Which statement concerning vortices caused by helicopters is correct?
(1) Helicopter vortices are generally weak and dissipate rapidly.
(2) The size and weight of the helicopter has a direct influence on the intensity of the vortices.
(3) Helicopter vortices are less intense than the vortices of an aeroplane of the same weight.
(4) Wind does not influence the movement of vortices generated by a helicopter in hovering flight.
(2) The size and weight of the helicopter has a direct influence on the intensity of the vortices.
What effect would a light crosswind have on the wing tip vortices generated by a large aeroplane that had just taken off? A light crosswind
(1) could cause one vortex to remain over the runway for some time.
(2) would rapidly dissipate the strength of both vortices.
(3) would rapidly clear the runway of all vortices.
(4) would not affect the lateral movement of the vortices.
(1) could cause one vortex to remain over the runway for some time.
