1
New cards
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
2
New cards
What does IMSAFE stand for?
Illness, Medication, Stress, Alcohol (and drugs), Fatigue, Emotion
3
New cards
Runway Incursions
Unauthorized vehicle on runway
4
New cards
Hot Spots
High risk of incursion areas
5
New cards
Runway Guard Light
On taxiway where it joins a runway
6
New cards
Runway Layout
Numbers are magnetic heading
7
New cards
How do you find the opposite end of a runway number?
Subtract 18 from the number or do +2 -2
8
New cards
How do you specify parallel runways?
Specify left or right (or center) based on pilot’s perspective
9
New cards
What is a chart supplement?
reference for all airports in the country (broken down into regions)
10
New cards
How do you identify taxiways and runways?
Letters = taxiway; numbers = runways
11
New cards
What is a non movement area?
Area where there is no talking on the radio
12
New cards
What is the intake stroke?
Intake valve opens to allow fuel-air mix in
13
New cards
What is the compression stroke?
Intake valve closes, push fuel-air mix together, piston goes up
14
New cards
What is the power/combustion stroke?
2 spark plugs (piston reaches top), mix catches and pushes piston down
15
New cards
What is the exhaust stroke?
Piston rises again, exhaust valve opens
16
New cards
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
17
New cards
What is detonation?
Fuel/air mixture exploding not smooth burning, rough engine running, overheat, loss of power
18
New cards
How to correct detonation?
Reduce power, increase airspeed, richen mixture, increase fuel grade
19
New cards
What is pre ignition?
Fuel/air lights before you want it to-before spark plug can light something else does
20
New cards
How do you correct pre ignition?
Lean engine, correct fuel grade, lower engine temp
21
New cards
What is a gravity-fed fuel system?
Use gravity for pressure (ex. high wing)
22
New cards
What is a pressure fuel system?
Engine driven fuel pump (electric for backup)
23
New cards
What are the different fuel colors?
Red (80 oct.) Green (100 oct.) Blue (100LL) Jet Fuel (clear/straw)
24
New cards
What is the fuel gauge?
It is unreliable, always visually check, can’t be used by an engine
25
New cards
What is an induction system?
Mixing of fuel and air
26
New cards
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
27
New cards
What is carb heat?
Meant to defrost icing, reduced power and increases engine roughness, unfiltered air
28
New cards
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
29
New cards
What is the fuel to air mixture ratio?
1:15 (fuel:air)
30
New cards
What is a magneto?
The things that light the engine (spark plugs, 1 magneto-combustion takes longer, 50 rpm difference between both)
31
New cards
What is the purpose of ATC?
Keep airplanes from bouncing off each other
32
New cards
What is a controlled airport?
Active control tower that manages airspace within (about) a 5 mile radius
33
New cards
What is an uncontrolled airport?
No or inactive tower (listen and report on CTAF frequency)
34
New cards
What is ATIS?
Pre-recorded broadwcast with airport advisory information, updated when airport conditions change
35
New cards
What is ground control?
Movement of aircraft on airport surface (in movement areas)-121.X
36
New cards
What is tower control?
Aircraft on runways and air
37
New cards
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
38
New cards
What do you do about wind when taxiing?
Turn into wind to prevent flipping (front), back down elevator
39
New cards
What is torque?
Airplane wants to roll in opposite direction of airplane
40
New cards
What is a spiraling slipstream?
Hits tail and creates left force on nose
41
New cards
What is p-factor?
Asymmetric thrust from propellers
42
New cards
What is precession?
When airplane is spinning one way and it doesn’t want to do the other way
