Q

Swept wing aircraft have a higher critical mach number because…

A

The relative airflow over the swept wing surface is allowed to move somewhat outboard towards the wing times so the air encounters less apparent camber and does not accelerate as quickly over the top of the wing.

22
Q

Va – What is it and what does it mean?

A

Design Maneuvering Speed. Highest safe airspeed for abrupt control deflection for operation in turbulence or severe gusts.

23
Q

What impact does weight have on Va?

A

Va decreases as weight decreases.

24
Q

V2 – What is it and what does it mean?

A

Takeoff safety speed for jets, turboprops or Transport category aircraft.
Best climb gradient speed (best altitude increase per mile with most critical engine inop); Min speed to be maintained to at least 400’ AGL.

25
Q

Vne – What is it and what does it mean?

A

Never Exceed speed – RED Line.

26
Q

Explain the 60:1 rule.

A

At 60 DME from the VOR, 1nm between every degree of radial.

27
Q

What is the Standard Rate of Turn

A

3 degrees per second

28
Q

If the field elevation is 800 feet and the altimeter setting is 29.75, what is the pressure altitude?

A

29.92 - 29.75 = 0.17
0.17 * 10(per .01) = 170ft
800 + 170 = 970ft pressure altitude
Since you have to ADD the 0.17 to get to 29.92, ADD the difference (170ft) to the field elevation.

29
Q

Unstable air is a characteristic of high or low pressure weather system?

A

Low.

30
Q

What is the rate of descent to fly an ILS (3 degrees) at 180 knots?

A

180/2 = 90, add a ‘0’, 900fpm.

Groundspeed divided by 2, add a ‘0’.

31
Q

What is calibrated airspeed?

A

Indicated airspeed corrected for instrument error.

32
Q

Thrust and drag are equal when?

A

Level, unaccelerated flight.

33
Q

What do Fowler flaps do?

A

Travel aft and down, increasing camber.

34
Q

Flaps were designed on aircraft for what reason?

A

Decrease approach speed, thereby decreasing landing distance.

35
Q

Holding a constant Mach, TAS ________ in the climb until around FL350. After that it remains fairly constant. AoA ________.

A

Decreases; increases.

36
Q

Critical Mach decreases as altitude ________.

A

Increases.

37
Q

What two factors affect lift in a turn?

A

That a pilot can control, angle of attack and airspeed.

38
Q

As airspeed increases, drag increases ________.

A

by the square of the speed increase.

39
Q

What effect does altitude have on stall speed?

A

An increase in altitude will increase stall speed.

40
Q

What speed is affected when you have a contaminated runway?

A

V1 decreases with a contaminated runway.

41
Q

Braking energy is most dependent on _______.

A

Aircraft weight.

42
Q

If you have two 6V batteries and want to make 12V, do you conned them in series or parallel?

A

Series. Connecting in parallel gives you 6V but doubles the amps.

43
Q

How is engine oil cooled on most jets?

A

Fuel heat transfer.

44
Q

With a Pt2 probe iced over, what indications will you get?

A

A falsely high EPR.

45
Q

How does turbulence affect stall speed?

A

Increases stall speed due to an increase in load factor..

46
Q

Describe the difference between a slip and a skid.

A

Slip: Turn without enough rudder.
Skid: Turn with too much rudder.

47
Q

What indications can you expect with a blocked pitot tube?

A

Airspeed indicator acts like an altimeter.

48
Q

Convert IAS to TAS.

A

IAS + (0.02Flight Level)IAS = TAS

49
Q

What is radius of ten a function of?

A

Velocity and load factor.

50
Q

What is radius of ten a function of?

A

Velocity and load factor.

51
Q

Cruising along, you experience total AC power failure. You are able to get one generator back on line. How do you know how much power the generator is creating?

A

The Kilowatt meter.
