Chapter 6 - Flight Characteristics Flashcards
At aft centers of gravity, what is the pitch force required?
9 pounds per G
At forward centers of gravity, what is the pitch force required?
12 pounds per G
The trim rate of each axis changes with airspeed. (T/F)
False, trim rate is constant throughout the airspeed envelope of the aircraft
During speed break extension, what does elevator trim do? How?
Elevator is trimmed nose down
Due to the speed brake - elevator trim interconnect
What are the 3 factors that effect glide performance?
- Airspeed
- Configuration
- Coordination
What activates the stick shaker?
The AOA system
What is the minimum stall warning airspeed provided by the stick shaker?
5 knots
In all configurations, during power off stalls, the aircraft buffet occurs how many KIAS before stall?
3 KIAS
During an unaccelerated power-on stall, at what airspeed does the aircraft buffet occur prior to stall?
There is little perceptible buffer prior to the stall
With 100% torque, what nose attitude is possible during entry ot a wings level stall?
45 degrees
What is the defining characteristic of an upright, wings-level stall?
A roll-off or wing-drop, together with an increased buffet
During a wings-level power on stall, what is the tendency of the aircraft and why?
A left rolling tendency is induced at stall by engine torque before reaching full aft stick
Above what torque setting may it not be possible to prevent a left roll-off at a stall?
60%
What aggravates the roll-off stall tendency more, flaps or landing gear?
Flaps, landing gear have little effect on stall characteristics
Altitude loss from a wings level stall is usually less than what?
100 ft
