The exhaust gas temperature (E.G.T ) indicator on a gas turbine engine provides a relative indication of the
- turbine inlet temperature.
- temperature of the exhaust gases as they pass the exhaust cone.
- exhaust temperature.
The exhaust gas temperature (EGT) is typically defined as the gas temperature at the exit of the turbine

Nozzle guide vanes give a
- pressure increase, velocity decrease.
- pressure increase, velocity increase.
- pressure decrease, velocity increase.
nozzle guide vane are associated with compression section, so they're used to maximise compression performance (they're divergent) by decrease the speed & increasing pressure gain for each stage

Upon what quality or characteristic of a lubricating oil is its viscosity index based?
- Its rate of flow through an orifice at a standard temperature.
- Its rate of change in viscosity with temperature change.
- Its resistance to flow at a standard temperature as compared to high grade paraffin base oil at the same temperature.
viscosity is defined as mm^2/s for a determined temperature.
Extending a leading edge slat will have what effect on the angle of attack of a wing?
- Increase the angle of attack.
- Decrease the angle of attack.
- No effect on angle of attack.
The effect of the slat is to prolong the lift curve by delaying the
stall until a higher angle of attack. how does it possible that the angle of attack decreases?
