Q

What happens when static port is blocked

A

ASI: under read in climb over read in decent
ALT: freeze
VSI: Go to zero

20
Q

CFS update schedule

A

Every 56 days

21
Q

20% rule

A

An airplane can take a crosswind component of 20% of its landing configuration stall speed (VSO*0.2)

22
Q

Effect of rain on windscreen

A

Causes things to appear lower and further away than actual. something 1/2 a mile away will look ~ 260’ lower

23
Q

Hypoxia symptoms

A

Euphoria, impairs night vision, reaction time, reasoning, fatigue, loss of consciousness

24
Q

Carbon monoxide symptoms

A

-Blurred thinking
-Dizziness/headache

25
Q

What is mountain effect?

A

Wind rushing around mountains of through valleys lower pressure in the area causing altimeter to read too high (true altitude will be lower)

26
Q

Turbine engine pressure ratio

A

Pressure of intake air vs discharge pressure

27
Q

Turbine engine bypass ratio

A

Ratio of air going through vs. around the intake and combustion sections

28
Q

What is alternate air?

A

Allows induction air to bypass normal induction system in case of impact ice

29
Q

Under what conditions are vapor lock most likely?

A

High altitude and temperature

30
Q

ADF modes

A

-ADF mode
-Antenna mode (Loop antenna disengages to hear weak signal)

31
Q

How to reduce the icing probability in turbine aircraft

A

Use fuel system icing inhibitor (Prist)

32
Q

Effects of center of gravity on airplanes

A

Rear C of G = unstable and low stall speed

Forward C of G = Stable and high stall speed

33
Q

What is an intercooler

A

Cools air that has been heated for compression before induction into engine

34
Q

PAPI system lights order

A

Red comes from the right as you get lower

35
Q

Where does the heat from the carb heat come from

A

Shroud around the exhaust pipes

36
Q

PT6 engine sections front to back

A

Power, Compressor, Accessory

37
Q

As weight decreases Va will

A

Decrease

38
Q

Turbocharging benefits

A

-Maintain sea level pressure at higher altitudes
-increases power at low altitude

39
Q

A weak battery when starting turbine engine will cause _____

A

A hot start (Engine will not spin up to provide sufficient cooling)

40
Q

Most fuel efficient engine type

A

Diesel

41
Q

Effect of using automotive fuel in aircraft piston engine

A

Increases range in which carb ice can form due to increased vapor pressure

42
Q

Turbo charger waste gate purpose

A

To prevent excessive manifold pressure (over-boost) by limiting air inducted into engine

43
Q

Jet fuel types and functions

A

Jet A - common in warmer climates

Jet A1 - good in colder weather

Jet B - For extreme cold

44
Q

V1

A

Rotation speed

45
Q

Loss of oil pressure effect
single vs multi engine

A

Single - Full fine. Prop designed to increase pitch with oil pressure

Multi - Feather. Prop designed decrease pitch with oil pressure
