Chapter 2.6 - Exam Review Flashcards
What happens to the Lift and Drag on a Wing if the Stalling Angle is exceeded?
The Lift decreases with the Drag increasing.
Once the Stalling Angle of a Wing has been exceeded, the centre of pressure rapidly moves (forwards towards the leading edge/backwards towards the trailing edge)?
Backwards towards the trailing edge.
Frost and Ice on the Wings is likely to (increase/decrease) an Aircraft’s level flight Stall speed?
Increase.
If an Aircraft is flown at a lesser Weight than its maximum allowable gross Weight in level flight, its Stall IAS will be (higher/lower) than its stated level flight Stall speed?
Lower.
An increase in ‘apparent Weight’ will (increase/decrease) an Aircraft’s level flight Stall speed?
Increase.
The first actions in recovering from a power-on Stall are to ‘break’ the Stall by decreasing the (Angle of Attack/Airspeed) and the same time, (increasing/decreasing) power to minimise height loss?
- Angle of Attack.
- Increasing.
For the same Weight (or ‘apparent Weight’), an Aircraft’s level flight stall IAS (will/will not) change with changes in Altitude?
Will not.
Which is more desirable design feature, a Wing which Stalls first at the roots or one that Stalls first at the tips?
A Wing which Stalls first at the roots.
One desirable Stall characteristic in modern, Light Training Aircrafts is a (gradual/sharply defined) Stall?
Gradual.
Another desirable Stall characteristic is a (nose-up/nose-down) pitching tendency?
Nose-down.
In a Spin, the Wing (is/is not) Stalled?
Is.
In a Spiral Dive, the Wing (is/is not) Stalled?
Is not.
The best way to discriminate between a Spin and a Spiral Dive is by reference to the (rate of descent/Airspeed)?
Airspeed.
Describe the Airspeed in a Spin as compared to that in a Spiral Dive?
- Airspeed is low and remains constant in a Spin.
- Airspeed is high and increases in a Spiral Dive.
If a Spin is entered with power on, why should the first action be to close the Throttle?
To minimise the height loss.
