Flashcards in EASA Prep Deck (47):
Inputs to the Air Data Computer
TAT, Ps, Pt, AoA, Electric
Bar to psi
1 bar = 15 psi
CVR must record:
Aural environment of the flight deck
Radio communications made/received by the flight crew,
Nav aid signals and approach aids & identifiers.
Inter flight crew communications,
Fight crew use of the interphone & comms over PA system.
Components of a CVR
1. A microphone
2. A recorder in compliance with the shock and fire resistance standards
Airspeed Indicator inputs
Total pressure in the capsules
Static pressure outside; in the case.
Rate One Turn
3 degrees per second.
TAS.10 +7 = opt. AoB
What is EPR?
EPR = Turbine Outlet Pressure / Compressor Inlet Pressure
Shown as present, commanded, limit.
The first spool is the low pressure compressor
Pilot has the ability to make inputs to:
AUTOMATIC PILOT by movement of the NORMAL control wheel
A synchroscope is used on aeroplanes to
Set several engines to the same speed.
A synchroscope is used to:
i. Reduce structural vibration and noise.
ii. Allow symmetrical thrust and fuel consumption.
How is a synchroscope used to balance the RPM on a twin turboprop aircraft?
A signal from each RPM gauge feeds the synchroscope. The master engine is connected to the rotor, and the slave engine is connected to the stator, with the difference being displayed in the cockpit, enabling the crew to balance the RPM manually.
What are the inputs to the FD in ALT HOLD mode?
Altitude Deviation & FPA/Pitch Angle
What is the technique of Computer Memory based on?
Normal operating mode of an FMS
Dual mode, exchange data
"ON BAT/ON DC"
INS is running on its own internal battery.
Radio Altimeter antennas
One to transmit, one to receive.
Attitude Indicator - which parts move, and which parts don't
Yellow/white aircraft symbol is fixed to the case , horizon and sky move.
What feeds the Vertical Speed Indicator?
Which is the most sensitive in turbulence?
What happens in a Thermocouple with increasing temperature?
Voltage increases as temperature increases at the hot junction
Electronic Centralised Aircraft Monitoring
Engine Instrument Crew Alerting System
Purpose of a BUS in computers
Transfer address, data, control signals
Function of an inner loop
Operating range of a Radio Altimeter
From 2,500 ft to the ground, with an accuracy of +-1.5% and +-2ft below 500ft
EGPWS warns how many seconds before impact?
Instrument, Position, Manouever
The EPR is blocked on takeoff. What does it read?
What do FANS 1 routes require?
What purpose do Auto Throttles serve on startup?
What is apparent drift a function of?
Bar to Pascal
1 Bar = 100,000 Pascal
Twisting of the shaft
Components of the Flight Data Recorder
Chip, Magnetic Tape
How is hydraulic pressure measured?
TRANSDUCER equipped with an INDIRECT INDICATOR
A Flight Warning System (FWS) alerts crews to abnormal situations by:
Aural and visual alerts.
How is total fuel consumption calculated?
INTEGRATING fuel flow in respect to time
Difference in speed of rotation of engines
The main inputs to the flight envelope protection system are
Bank Angle, Angle of Attack
What is a volatile memory
A memory that requires an electrical source to maintain information
Types of vibration sensors
Piezoelectric crystals, and magnets
Intruding aircraft is equipped with a Mode C Transponder - what traffic alerts will TCAS generate?
TA/RA as normal.
The measurement of the turbine temperature or of the EGT is carried out at the:
Outlet of the high pressure stage of turbine.
The input signal of the amplifier of the gyromagnetic compass resetting device originates from the:
Landing will not be completed automatically, but no out of trim will occur nor flight path deviation.
