IFR Flashcards
What kind of altimeter do we have?
Barometric/sensitive altimeter *?
What are the different types of altitudes
Explain the pitot/static system
What are the different types of airspeeds?
True airspeed needs explaining
IAS: Airspeed read directly from the airspeed indicator without corrections.
CAS: IAS corrected for position and instrument errors.
TAS: CAS corrected for nonstandard temperature and pressure.*
GS: TAS adjusted for wind (headwind or tailwind).
EAS: Equivalent airspeed EAS is CAS corrected for compression of the air inside the pitot tube. (look at the phak)
Explain what happens to the pitot static instruments for partial and full blockage
How does the attitude indicator work?
It receives its information from AHRS
How does the AHRS work?
attitude heading reference system
attitude
rate of turn
slip/skid
Air Data computer
Outside air temp
airspeed
altitude
vertical speed
Magnetometer
Magnetic Field Detection:
The magnetometer detects the Earth’s magnetic field to determine the aircraft’s heading. It uses highly sensitive sensors, such as fluxgate or solid-state magnetometers, to measure the strength and direction of the magnetic field.
If your airspeed, altitude, and vertical speed show red X’s what happened?
The Air Data computer is not working
HSI horizontal situation indicator
(directional gyro)
receives its information from the magnetometer, which feeds information to the AHRS unit and then out to the PFD
What is UNOS?
What is a standard rate turn?
are all instrument turns standard rate?
how does the turn coordinator work?
how does the Bank indicator work?
how does the slip skid indicator work? (Inclinometer)
Gyroscopic instruments are…
attitude indicators
heading indicators
turn indicators
turn and slip indicator
turn coordinator
What are the gyroscopic instrument errors
turn first then bug
what are the primary instruments in straight and level flight
altimeter
heading indicator
airspeed indicator
what are the steps when climbing
pitch up
full power
when descending
power down
pitch down
1800-1900 rpm
what is the difference between baring and radial
