Constant voltage with a reducing current.
Regarding the gas flow in the combustion section of an ideal gas turbine engine:
Pressure is constant and temperature increases
The angle of attack of compressor blades in a gas turbine engine depends primarily on -
True airspeed, RPM and compressor outlet pressure
The CSD of a large jet aircraft electrical system is required to control
AC generator output to ensure a constant output frequency
The item of information not displayed on the Electronic Attitude Director Indicator (EADI) of a B767 300 ER is

In an axial flow compressor, the blades experiencing the greatest air loads are
The small rear rotors
In the turbine of an air cycle machine, bleed air supplied from engines undergoes -
a decrease in pressure and a decrease in temperature
In a supersonic air stream, the static pressure behind the expansion wave -
Decreases
In an aircraft flying beyond MCRIT, turbulence felt through the elevator controls is likely to be due to
High speed buffet
If wing sweepback is increased for the same wing area, wing section and aspect ratio, for a given angle of attack -
lift coefficient and drag will both decrease
On the CDU of an FMC some pages contain lines for data entry by the crew to programme the FMC for the flight under the prevailing conditions of weather and gross weight
Concerning the entry of data into the CDU
data which is required to be entered as mandatory information for the operation of the FMC is indicated by boxes on the corresponding line on the CDU screen, while data which is optional but not essential for FMC computations is indicated by dashed lines
In a turboprop powered aircraft, the pilot controls the engine power output in flight -
by varying the fuel flow via the fuel control unit

To act as a fluid reservoir
Conditional waypoints are shown on the Legs Page of the CDU
