Q

What is Magnetic Variation?

A

Angular difference between true geographic north and south and the magnetic north pole and magnetic south pole causing a deviation between magnetic compass reading and true north

What is Magnetic Dip?

A

Tendency of a magnet to align with the Earth’s magnetic field lines, North end of needle dip down in N. hemisphere, up in S. hemisphere

15
Q

Magnetic Dip- Turning errors

A

Turn from a northern heading, compass briefly turns in opposite direction.

Turn from southern heading, cause compass to turn in correct direction but will be faster rate

Q

ANDS- (N. Hemisphere)

A

Accelerate North
Decelerate South

19
Q

Oscillation Error

A

Movement of compass card inside the compass fluid. May be due to maneuvers

20
Q

Stall

A

When an aircraft exceeds the critical angle of attack

21
Q

Parasitic Drag

A

Velocity increases, drag increases
(aircraft form, interference, skin friction)

22
Q

Induced Drag

A

Velocity increases, Induced drag decreases

Byproduct of lift, high pressure seeks a low pressure.

As velocity increases less time for the pressure to hit the trailing edge of the wing.

23
Q

Spin Recovery

A
  1. Power to Idle
  2. Ailerons Neutral
  3. Rudder Opposite Direction
  4. Yoke Forward
24
Q

Do both wings stall in a spin?

A

Both wings are, but one wing is in a deeper stall than the other.

25
Q

Wind Sheer

A

Wind direction or speed change over a vertical or horizontal distance.

Can cause a sudden loss of airspeed and altitude

26
Q

Wind Sheer Types

A

Vertical, Horizontal, Updraft/Downdraft

27
Q

Aerodynamics of Flight

A

Lift
Weight (gravity)
Thrust
Drag

28
Q

How do you control lift?

A

Airspeed, pitch, flaps

29
Q

Downwash

A

Pressure back of wing

30
Q

Wingtip Vertices

A

Move with the wind
Sink- 500- 1,000 ft/min

31
Q

When is wake turbulence the most dangerous?

A

Aircraft is HEAVY, CLEAN, and SLOW (higher induced drag)

32
Q

Stages of a Spin

A

Entry- stall itself

Insipient- Initial wing drop (1.5 -spin)

Developed spin- initial spin (3-4 spins)

Recovery- power idle, wings level, opposite rudder, yoke forward

33
Q

Characteristics of forward CG

A

More stable (longitudinal stability)
Less fuel efficient (more drag)
Higher stall speed (higher Angle of Attack)
Good stall recovery characteristics

34
Q

Characteristics of aft CG

A

Less stable (longitudinal stability)
More fuel efficient (less drag)
Lower stall speed
Bad stall recovery characteristics

35
Q
