1

What is the difference between read + do and flow?

Read + do uses a physical checklist and is completed by reading and doing, flow is memorized and more efficient

New cards
2

What does IMSAFE stand for?

Illness, Medication, Stress, Alcohol (and drugs), Fatigue, Emotion

New cards
3

Runway Incursions

Unauthorized vehicle on runway

New cards
4

Hot Spots

High risk of incursion areas

New cards
5

Runway Guard Light

On taxiway where it joins a runway

New cards
6

Runway Layout

Numbers are magnetic heading

New cards
7

How do you find the opposite end of a runway number?

Subtract 18 from the number or do +2 -2

New cards
8

How do you specify parallel runways?

Specify left or right (or center) based on pilot’s perspective

New cards
9

What is a chart supplement?

reference for all airports in the country (broken down into regions)

New cards
10

How do you identify taxiways and runways?

Letters = taxiway; numbers = runways

New cards
11

What is a non movement area?

Area where there is no talking on the radio

New cards
12

What is the intake stroke?

Intake valve opens to allow fuel-air mix in

New cards
13

What is the compression stroke?

Intake valve closes, push fuel-air mix together, piston goes up

New cards
14

What is the power/combustion stroke?

2 spark plugs (piston reaches top), mix catches and pushes piston down

New cards
15

What is the exhaust stroke?

Piston rises again, exhaust valve opens

New cards
16

How are the 4 cylinders positioned?

Straggled so they are not doing the same thing at the same time, fire quickly but only one providing power at a time

New cards
17

What is detonation?

Fuel/air mixture exploding not smooth burning, rough engine running, overheat, loss of power

New cards
18

How to correct detonation?

Reduce power, increase airspeed, richen mixture, increase fuel grade

New cards
19

What is pre ignition?

Fuel/air lights before you want it to-before spark plug can light something else does

New cards
20

How do you correct pre ignition?

Lean engine, correct fuel grade, lower engine temp

New cards
21

What is a gravity-fed fuel system?

Use gravity for pressure (ex. high wing)

New cards
22

What is a pressure fuel system?

Engine driven fuel pump (electric for backup)

New cards
23

What are the different fuel colors?

Red (80 oct.) Green (100 oct.) Blue (100LL) Jet Fuel (clear/straw)

New cards
24

What is the fuel gauge?

It is unreliable, always visually check, can’t be used by an engine

New cards
25

What is an induction system?

Mixing of fuel and air

New cards
26

Why aren’t carburetor engines not very common?

Icing (reduced pressure and decreased temp), doesn’t produce an even mixture, droplets of wet fuel, maneuvers affect float

New cards
27

What is carb heat?

Meant to defrost icing, reduced power and increases engine roughness, unfiltered air

New cards
28

What is fuel injection?

Fuel injected directly into cylinder, don’t have to worry about icing, better flow, faster throttle but difficulty starting a hot engine

New cards
29

What is the fuel to air mixture ratio?

1:15 (fuel:air)

New cards
30

What is a magneto?

The things that light the engine (spark plugs, 1 magneto-combustion takes longer, 50 rpm difference between both)

New cards
31

What is the purpose of ATC?

Keep airplanes from bouncing off each other

New cards
32

What is a controlled airport?

Active control tower that manages airspace within (about) a 5 mile radius

New cards
33

What is an uncontrolled airport?

No or inactive tower (listen and report on CTAF frequency)

New cards
34

What is ATIS?

Pre-recorded broadwcast with airport advisory information, updated when airport conditions change

New cards
35

What is ground control?

Movement of aircraft on airport surface (in movement areas)-121.X

New cards
36

What is tower control?

Aircraft on runways and air

New cards
37

What is a proper ATC call up?

Who we’re talking to, Who we are, where we are, with ATIS and what we want to do

New cards
38

What do you do about wind when taxiing?

Turn into wind to prevent flipping (front), back down elevator

New cards
39

What is torque?

Airplane wants to roll in opposite direction of airplane

New cards
40

What is a spiraling slipstream?

Hits tail and creates left force on nose

New cards
41

What is p-factor?

Asymmetric thrust from propellers

New cards
42

What is precession?

When airplane is spinning one way and it doesn’t want to do the other way
