Ch 6: Circuits - FLAPLESS Flashcards
Ground Effect: (Pg 82)
Is an aerodynamic quality that sees a reduction in INDUCED DRAG, when aeroplane is w/in 1 wingspan of the surface
Smaller wingtip vortices and smaller induced drag ‘cushion’ the aeroplane above ground and prevent desired sink rate to develop
Flap Extension Speed (Vfe): (Pg 82)
Represented by top of WHITE ARC in ASI, is the max speed allowable w/ flaps extended, and that extension of flaps can be conducted
Approach Threshold Speed (Vat): (Pg 82)
Speed at which the aeroplane should cross the threshold and will be equal to the landing speed (Vref) in nil wind
Crosswind landings often… (Pg 83)
Performed w/ less than full flaps extended
Downwind, once aeroplane is abeam threshold and aim point passes behind trailing edge: (Pg 84)
PAST:
P = 1300, Carby Heat ON
A = 1/3 grnd
S = 80kts (Vref)
T = as req for higher nose attitude
Downwind may be extended slightly to allow time to…. (Pg 84)
Wash off speed, and settle into approach config, will also accomodate flatter approach path, should still stay w/in gliding distance from rwy
Base turn and Base leg will have… (Pg 84)
Higher nose attitude
Will have same work cycle: (Pg 84)
AAA
Attitude - 1/3 grnd
Airspeed - 80kts
Aspect - If too high/low
Final will have a higher nose attitude….. (Pg 84)
Flatter approach path, and greater airspeed, so forward visibility is reduced
Work Cycle AAA
Aimpoint - no.s 1/4 up in windscreen
Airspeed - 80kts –> 75kts towards 300ft
Aspect - If too high/low
If too fast… (Pg 85)
Reduce power and raise nose slightly
Given reduced drag w/ no flaps… (Pg 85)
More time will be required to wash off airspeed, touchdown will be further along on the rwy
For Full-Stop Landing… (Pg 85)
Greater landing distance will be required
For Touch + Go Landing… (Pg 85)
Airspeed will not reduce as much as normal, and time required to accelerate to Vr will also be reduced
