BMA 6 Flashcards
Aircraft piston engines are characterized by:
high thrust to weight
Type of aircraft engines and their characteristics:
Uses _______to convert pressure into rotating motion.
Turbojet engines with propellers __________.
Hybrid of turboprop / turbojet ______________________________
PISTONS / TURBOPROP / TURBOFAN (modern a/c)
A turbine engine
is less complex than a piston engine
A turboprop aircraft
is speed limited by its propeller(s).
A high bypass turbofan engine
is quieter than a turbine engine.
Small general aviation and military aircraft run on which type of electricity?
General aviation ____?
Military _____?
DC / AC
The electrical system with constant voltage is _________.
DC
A ______ is used to protect aircraft electrical systems from overload.
Circuit breaker
Gyroscopic flight instruments are _______, _______ and _______, and what are their functions?
Instruments:
attitude, heading indicator and turn coordinator
Functions:
Attitude:
aircraft pitch, roll and orientation with respect to the horizon
Heading indicator:
aircraft heading
Turn Coordinator:
rate and “quality” of the turn
Pitot-static instruments are ________, ________ and ________, and what are their functions?
Instruments:
air speed indicator, vertical speed indicator, and altimeter
Functions:
Air Speed indicator-
aircraft’s speed by comparing pitot pressure to static pressure
Vertical Speed Indicator-
accurate indication of rate of change of altitude
Altimeter-
measures the height of the aircraft relative to sea level
If indicated airspeed (IAS) is held constant in a climb, true airspeed (TAS) will increase?
TRUE
All aircraft flying above FL 180 in the United States will use a common altimeter setting of __________.
29.92 in
What are the types of airspeed and what do they tell the crewmembers?
Indicated Airspeed: Uncorrected airspeed read directly from an indicator (IAS)
Calibrated Airspeed: IAS corrected for static source error (CAS)
True Airspeed: Corrected for density altitude and compressibility (TAS)
Groundspeed: Speed over the ground (TAS +/- winds)
What are the types of altitude and what do they tell the crewmembers?
True altitude: actual aircraft’s height above sea level usually expressed as MSL (mean sea level)
Absolute altitude: the height of an aircraft above the terrain over which it is flying
Indicated altitude: this is the uncorrected altitude read directly from the altimeter
Pressure altitude: this is the altimeter reading that corresponds to the altitude in the standard atmosphere where the pressure is the same as you are
Density altitude: the pressure altitude corrected for temperature variations
Transition altitude: the altitude above which the standard altimeter setting of 29.92 will be used
