100
These are the two pitot-static instruments required on all aircraft.
What are altimeter and airspeed indicator?
100
This is the barometric setting required for all altimeters flying above 18,000 feet.
What is 29.92?
100
The vertical speed indicator connects to this type of pressure?
What is static pressure?
100
A plane flying at Mach 1 is flying how many times the speed of sound?
one.
100
This is the difference between two pressures.
What is differential pressure?
100
This is the type of flying used when visibility is non-existent.
What is instrument flight rules?
100
What type of pressure are you measuring when you check your tires?
Gage pressure.
200
This must be done whenever a pitot-static instrument is installed.
What is a leak check?
200
What is the definition of pressure altitude?
It is the altitude that would show on an altimeter if conditions are at standard day 29.92.
200
What instrument measures the rate of change in feet/minute?
The VSI!
200
These two airspeeds are the same in standard day conditions.
What are True Airspeed and Indicated Airspeed?
200
This is pressure measured against ambient atmospheric pressure.
What is gage pressure?
200
This is the type of flying where you can see everything around you through the aircraft windows.
What is visual flight rules?
200
What type of pressure is measured for cabin pressure?
Absolute pressure
300
This is the pressure created by the forward motion of the aircraft.
What is pitot pressure?
300
This is pressure altitude corrected for temperature.
What is density altitude?
300
True or false? The ASI measures airspeed as well as groundspeed.
False.
300
This is pressure measured against a vacuum.
What is absolute pressure?
300
You are flying your plane and not really paying attention to altitude, suddenly a striped window pops into view on your sensitive altimeter. What is it telling you?
You are below 10,000 feet.
300
What type of pressure is measure here for pitot/static pressure?
Differential pressure
400
This instrument is connected to both pitot and static.
What is the airspeed indicator?
400
Altitude stays at the same level even though the plane is descending. What is going on?
Static port is blocked.
400
This instrument has pressure driven pumps. What are the pumps called?
Instantaneous vertical speed indicator. Dash pots.
400
What is Calibrated Airspeed (CAS)?
The IAS corrected for instrument (lag) and position error.
400
This inside of this instrument looks a bit like a party favor and can measure temperature or pressure.
What is a bourdon tube?
400
You need to check the calibration of your altimeter with a Kollsman window? What information do you need, and what do you do?
You need to know your altitude and your sea level pressure for that day.
You would set the kollsman window to that day's sea level pressure. If the altitude displayed matches your altitude, the altimeter is calibrated correctly.
400
What type of pressure is measured for engine manifold pressure?
Absolute pressure
500
How many instruments are connected to the pitot-static system and what are they?
Four: the ASI, VSI, and altimeter and Machmeter.
500
How does an altimeter know its altitude?
It reads the static pressure from the static port; as the aircraft goes up, the static pressure goes down because the atmospheric pressure goes down at higher altitudes, which the altimeter reads as an increase in altitude.
500
This device helps a vertical speed indicator measure vertical speed once it knows altitude.
What is a calibrated orifice?
500
Define True Airspeed.
This is airspeed corrected for lower air density at high altitudes, which would otherwise show a slower than actual airspeed.
500
This type of instrument is required if you are flying IFR.
What is sensitive altimeter?
500
What is the difference between a self-compensating true airspeed indicator and a manually corrected true airspeed indicator?
- A self-compensating true airspeed indicator has a temperature-compensated aneroid bellows that modifies the movement of the mechanisms as the outside air temperature changes.
- An externally manual adjustable airspeed indicator:
- Has an adjustment on the dial that can be used to adjust for atmospheric changes to give more accurate airspeed indication
500
If your static ports ices up on an unpressurized aircraft, where can you get static pressure?
From inside the cabin, with a valve that can be opened by pilots.
