« Regarding cabin differential pressure. The required valve in normal flight conditions is regulated by? A constant mass airflow is permitted.
« If the cabin pressure becomes negative? The negative pressure relief valve will open.
« During a normal pressurized climb after take-off the? Cabin pressure decreases more slowly than atmospheric pressure outside the aircraft.
« When increasing TAS? AoA of a fixed prop reduces.
« When increasing TAS? AoA of a constant speed prop increases.
« An EPR gauge reading normally, shows the ratio of? Jet pipe pressure to compressor inlet pressure.
« The fan in a high by-pass ratio turbo jet engine produces? The greater part of thrust.
« A gas turbine engine power change is achieved by? Changing the amount of fuel supplied.
« The cabin ROD is? The cabin pressure rises.
« In a modern jet airplane, how can landing gear be extended if there is a complete hydraulic system failure? Mechanically.
« The purpose of baffle check valves in fuel tanks is? To prevent fuel movement to the wingtip.
« The cabin altitude rises (aircraft in level flight) the differential pressure? Decreases.
« A hyd. Device similar to an electronic diode is a? Check valve.
« For a fan jet engine the by-pass ratio is? External airflow mass divided by the internal air flow mass.
« When the combustion gases pass through a turbine the? Temperature drops.
« Concerning the anti-skid system, what happens to the pressure? It decreases on the slower turning wheels.
« In a bootstrap cooling system, the supply of air first? Compressed, then goes through a heat exchanger and across an expansion turbine.
« What is the purpose of the pack cooling fans in the air condition system? Supplying the heat exchangers with cooling air during slow flight and ground operation.
« Engine bleed air used for air conditioning and pressurization in turbojet aircrafts is usually taken from the? Compressor section.
« In commercial transport aircraft the landing gear system is usually hydraulic.
« Thrust is achieved by the following formula? Force = mass x acceleration.
« When does the exhaust valve open? Before the B.D.C. of the power stroke.
« The camshaft turns with? Half the revolutions of the crankshaft.
« The primary function of an axial flow compressor stator vane is to act as a diffuser. What is the secondary function? Control the direction of the air to each stage of the compressor.
« What is the main purpose of the combustion section secondary air? Cooling of the liner gases.
« What purpose does the needle valve have in a carburetor? It controls the amount of fuel inside the float chamber.
« A fully fuel injected engine has the advantage of being? Fully aerobatic and not so susceptible to inlet icing.
« After a nice flight in a airplane with a fuel injected engine you decide to take a rest at an airport. It is 25¢XC OAT. When you shut the engine down you must be aware that the engine? Might perform a vapor lock.
« Manifold pressure is measured at the appropriate point in the? Induction system.
« Which statement is true regarding axial flow compressors? The speed at the tips of all rotating airfoils within the engine is carefully governed to keep the airflow over any part of the engine form creating shock waves.
