Theory Of Flight 2 Flashcards
Name the 3 axes on an plane
Longitudinal (roll) , vertical (yaw) , lateral (pitch)
What is the type of ailerons that we have on a C-150?
Frise ailerons
Is the yaw used to obtain a particular flight attitude?
No
What is the load factor?
The ratio of lift of an aircraft and weight
What is the load factor for a straight and level flight?
1 or 1g
What are the 4 phenomena that cause adverse yaw?
Precession (gyroscopique effect), slip stream, asymmetric thrust and torque
What’s cause the yawing movement
On the ground, the left tire is more flattened. Which leads to the aircraft yawing left
What’s the asymmetrical thrust?
It’s the yaw must be controlled with each power and attitude change
What’s the asymmetrical thrust?
It’s the yaw must be controlled with each power and attitude change
What are the two causes of the yawing movement?
Gyroscopic precession and slipstream
Depending on the applied power, the slipstream will cause :
A.more yaw
B.less yaw
C. More and less yaw
C
What’s the variable pitch for the propellers ?
It’s to control the angle of the propellers
What’s the best angle of climb vx
56 knots
What’s the best rate of climb Vy?
68 knots
What’s the definition of best rate of climb
The greatest gain in height in a given time
What’s the definition of best angle of climb
The greatest gain in height in a given distance
For the best angle of climb (vx) the wind can effect the climbing angle. If you have some head wind, the angle will be bigger or smaller?
Bigger
For the best angle of climb (vx) the wind can effect the climbing angle. If you climb and you have some tail wind, what’s gonna happen with the angle of climb
He will be smaller
What’s the speed for a normal climb?
65-75 knots
What’s the best glide speed ?
60 knots
What’s the circuit speed?
70 knots
If you have 10 degrees flaps how much speed do you lost?
5 knots
During turns, the lift force has two components, what are they?
- The vertical component
- The horizontal component
If you have à constant airspeed a larger angle of bank will result in a smaller or a bigger turn radius?
Smaller
If you have a constant angle of bank, a slower airspeed will result in a smaller or a bigger turn radius?
Smaller
True or false, turn increase the load of factors?
True
True or false, the greater the angle of bank, the greater the load factor?
True
True or false, in straight level flight, the aircraft has a load factor of 2 (or 2g)
False, it’s a load factor of 1 (or 1g)
What are the Va for a C-150
1600lbs > 97 knots
1450lbs > 93 knots
1300lbs > 88 knots
