Question 10

How much time should be allowed between each relight attempt?

Answer 10

30 seconds

Question 11

During flight through cloud/vapour, there may be a loss of thrust indicated by a drop in RPM of ___?

Answer 11

3 - 4%

Question 12

After 15 seconds of flight in zero of negative G, what might be noticed?

Answer 12

Increase in engine rumble

Question 13

What speed should be a glide be done above 25,000ft

Answer 13

M0.65

Question 14

Why is the gliding speed above 25,000ft important?

Answer 14

a. To avoid the risk of an undamaged engine ceasing to windmill
b. To put the aircraft at the correct KIAS to try a cold relight at or below 25,000 feet
c. To reduce canopy fogging up
d. To preserve battery life.

Question 15

Below what altitude is it okay to perform a slam acceleration after an aerodynamic stall?

Answer 15

Below 10,000 MSL

Question 16

During a suspected engine malfunction, above what altitude is a zoom not always required?

Answer 16

If above 25,000 MSL, time is not as critical and
the zoom is not always required as other factors
now come into play

Question 17

Indications of a compressor stall?

Answer 17

Loss of thrust with any of the following:
1. Fluctuating RPM (usually decoupled RPM/TGT movement - RPM falls, TGT rises)
2. Popping/banging sound
3.

Question 18

What does AOI say about compressor stalls which occur at low RPM?

Answer 18

If the compressor stall occurs at low RPM, the loss of thrust may not be noticed (at idle) and there may be no unusual noises. TGT may rise slowly (about 10 degrees per second). This can happen at higher altitudes and
slower speeds with severe distortion of intake flow.

Question 19

3 types of compressor stalls?

Answer 19

1. Compressor stall leading to flameout
2. Compressor stall that clears at idle
3. Compressor stall that does not clear at idle

Question 20

What should you do if ROT caption does not come on the EMP during an air relight?

Answer 20

If a relight is attempted and the ROT caption
on the EMP does not come on a LP shaft seizure is
confirmed, the relight attempt is to be stopped and the
ENGINE SEIZURE procedure is to be performed.

Question 21

4 indications of Engine Mech Damage?

Answer 21

a. Vibration.
b. Abnormal TGT or RPM.
c. Loss of thrust.
d. External sparks, trailing smoke and/or
momentary flames emitting from the exhaust
pipe.

Question 22

Why is it important to shut the engine down after a seizure?

Answer 22

After eitheror both seize, relighting will not be possible and cancause a risk of an engine fire. For these reasons the engine is to be shut down and all fuel turned off.

Question 23

How do you determine if the LP shaft has seized during a seizure?

Answer 23

No ROT on EMP after relight button pressed

Question 24

Give 2 indications of a seized HP shaft

Answer 24

a. RPM blank on EMP. A wind milling engine will
give more than 10% RPM in an undamaged
engine at normal gliding speed. However,
caution must be exercised with this indication
because with a damaged but unseized
engine, the RPM may be less than 10% RPM
and also show blank.
b. When observed RPM decrease is rapid
and goes blank on the EMP, a seizure has
occurred. This will likely be accompanied by
unusual noises.
c. If the HP shaft is seized, the Hyd 1 pressure
will eventually go to 0 after the accumulator is
depleted.

Question 25

Give 2 indications of an engine bay fire

Answer 25

1. Trailing smoke
2. External Flames
3. FIRE warning

Question 26

What is the possible cause of the FIRE warning light stated in the warning under Engine Bay Fire in Flight?

Answer 26

Exhaust gas leakage in the jet pipe bay can cause an overheat situation that will trigger the FIRE warning
light. Reduction of power can reduce the overheat condition and extinguish the FIRE warning light.

Question 27

What does the ECA do?

Answer 27

Provide outputs for:

a. Maximum TGT/NL control.
b. Warning of excessive TGT or NL.
c. Signal of correct LP shaft rotation.
d. ECA failure Caution.

Question 28

What does the compressor provide bleed air for?

Answer 28

1. Air conditioning unit, Anti-G, canopy seal
2. Bleed valve operation
3. Anti-icing for LP compressor nose fairing
4. Cooling of engine bearing housing
5. Engine oil pressurization
6. Fuel tanks pressurization

Question 29

What does the HP Shaft drive?

Answer 29

Through the external gearbox, the HP shaft drives:

1. HP/LP fuel pumps
2. Hydraulic pumps
3. Oil pumps
4. DC generator
5. HP RPM tacho-generator
