8.3 - Theory of Flight Flashcards
What is load factor
Load factor = Total lift / Aircraft weight
Identify
Which type of flap will create the most amount of drag?
Split flap
Notice that the split flap doesnt change the upper camber of the wing, having little effect on lift produced.
It does however impede into the bottom side of the wing trailing edge adding very large amount of drag
Flaps are also known as
High lift devices
What is the formula for glide ratio?
Glide ratio = Horizontal distance covered / Sink distance
What is the main advantage of a slat?
It delays the stall allowing you to fly at a high angle of attack
What effect would increasing the static stability have on dynamic stability and control?
- increases dynamic stability
- decreases control
Dutch roll is caused
tail wagging which causes the tail to yaw and roll from side to side
What does Vs stand for?
Stall speed
What is meant by TAS
True airspeed which is airspeed corrected for density
What is the density at sea level ISA?
1.225 kg/m3
Does the stall angle change in a turn?
'’The stalling angle is constant at all times (providing the wing geometery does not change).
The stall speed increases however, due to an increased wing loading.
What is the difference between the Vx and Vy climb?
