40
How does pressurization work?
Ambient air goes through a compressor, as the air is compressed it heats up rapidly. The heated air is sent through a cooling unit, like a fuel-air heat exchanger then released into the cabin through ducts. A series of outflow valves regulate how quickly air is released into the cabin. Air comes into the cabin quicker than it is released, creating a high pressure environment.

Indicates if the alternator is producing enough electricity by measuring the amps.
191
Why do we check for 23.3 amps before starting the aircraft?
To make sure we have at least 30 min on the emergency battery.
192
How does the alternator that produces AC electricity get converted to DC?
Using a rectifier.
193
Why use DC instead of AC?
No need for an additional conversion step making it more efficient and convenient, also less prone to electromagnetic interference.
194
What is DC?
Electrons flow steadily in a single direction
● Advantage
○ Easy to make
○ Good for short distance
● Disadvantage
○ Big
○ Doesn’t make a lot of power for low RPM
195
What is AC?
● Alternating current
● Electrons keep switching directions, going forward and then backwards
● Advantage
○ Can get the power in both directions.
○ Produce enough power during low RPM
○ Small size
○ Good for long distance
● Disadvantage
○ Harder to make
○ More expensive
196
What is static stability?
The initial tendency that the airplane displays after its equilibrium is disturbed.
197
What is positive static stability?
The initial tendency of the airplane to return to the original state of equilibrium after being disturbed.
198
What is neutral static stability?
The initial tendency of the airplane to remain in a new condition after its equilibrium has been disturbed.
199
What is negative static stability?
The initial tendency of the airplane to continue away from the original state of equilibrium after being disturbed.
200
What is dynamic stability?
How an airplane responds over time to a disturbance.
201
What is positive dynamic stability?
Oscillations dampen out over time.
202
What is neutral dynamic stability?
Oscillations that never dampen out.
203
What is negative dynamic stability?
Oscillations get worse over time.
204
Why do we slip instead of skid to land?
When you slip, the upper wing will stall first, and when upper wing stalls you can still recover because the wing will drop and decrease AOA. When you skid, the lower wing stalls first, so when the lower wing stalls, the upper wing produces more lift, and you will roll over and spin.
205
How to calculate gust factor?
(Gust wind - wind) / 2 = gust factor (add gust factor to final approach speed)
