7 Flashcards
A constant delivery hydraulic system requires:
A pressure regulator
Reverse thrust during the landing roll on a transport jet is most effective at:
High speed high RPM
The purpose of compressor bleed air vented overboard in a jet engine is to assist operations at:
Low RPM
An example of a conditional waypoint in the database of a Flight Management System (FMS) is:
An altitude
In supersonic airflow, static pressure behind an expansion wave will:
Decrease relative to pressure ahead of the wave
When a pilot selects auto-brakes 3 for a landing in a jet transport category aircraft, the system:
Will provide constant deceleration to a complete stop or until disengaged
The most common type of high pressure fuel pumps used in gas turbine engine fuel systems are
Swash plate
The function of the water separator in the cabin air conditioning system of a jet transport aircraft is:
To remove excess moisture in the conditioned air prior to entry into the cabin
To control cabin pressurisation in a standby mode, the pressure controller of an air-conditioning and pressurisation system requires inputs of:
Desired cabin altitude and cabin rate of change
The function of a static inverter in a constant frequency AC power generating system in a large jet transport aircraft is:
To provide 115VAC 400 Hz power in the event of total generator failure
Total Air Temperature (TAT) is used for thrust management on modern jet aircraft and is displayed on EICAS.
TAT is comprised of the static outside air temperature plus an additional factor caused mainly by:
Adiabatic compression
The main purpose of a hydraulic accumulator in a hydraulic system is:
To dampen out pressure fluctuations
The type of fuel boost pumps in a gas turbine engine fuel system are usually:
Impeller/Centrifugal type pumps
An advantage of a centrifugal compressor over an axial compressor in a gas turbine engine is:
Simplicity
Two 12 V 36A/H batteries are connected together in parallel, the result will be an output of
12V 72 A/H
