Start Procedure

Question 1

Normal Starter duty cycle

Answer 1

2min / 10s multimple

Question 2

Extended Engine Motorings

Answer 2

15min / 2min 1st two extended starts
5min/10min for third and subsequent starts

Question 3

Move engine start lever to IDLE DETENT too EARLY, what happends

Answer 3

hot start can occur

Question 4

Keep hand start level when and monitor…?

Answer 4

RPM, EGT,Fuel flow until stable

Question 5

ENGINE START switch fail to stay in GRD until starter cutout RPM, can cause hot start. Your procedure???

Answer 5

DONT re-enagage ENGINE START switch until engine RPM below 20% N2.

Question 6

FLuid leak (except continuous stream), any engine drain during exterior inspection.

Answer 6

Engine can be started. During start, ground crew report fluid leak from engine drain, continue engine start.

Question 7

FLuid leak as mentioned earlier, continuous after engine stable, do what?

Answer 7

*shut down engine for maintenance, or
*run engine @idle for UP to 5min.If leak stops, no maintenance action, or
*shut down and restart. Run engine for up to 5min. Fluid leak stops this time, no maintenance action.

Question 8

1st flight of day, airport elevation @/above 2000ft and temps below 5deg C?

Answer 8

Ignition switch BOTH

Question 9

Aborted Engine Start checklist for?

Answer 9

*N1/N2 not increase / increase very slowly after EGT increase.
*NO oil pressure engine stable, @ IDLE
*EGT don’t increase 15s after engine start level move to IDLE.
*EGT quickly nears, or exceeds the start limit.

Question 10

Explain start sequence to starter cutout?

Answer 10

Engine start switch GROUND
Verify N2 RPM increase
When N1 rotation seen and N2 @ 25%, or if 25% N2 not possible, at max motoring and minimum 20% N2, engine start level to IDLE detent.
Monitor FUEL FLOW and EGT (both crew)
@56% N2, Engine start switch moves to OFF.
If not, move switch to OFF.
Verify START VALVE OPEN alert extinguishes.
Call starter cutout.
Monitor N1, N2, EGT, Fuel Flow and Oil Pressure for normal indications while engine accelerates to stable idle.

Question 11

Max Motoring?

Answer 11

N2 acceleration less than 1% in approximately 5 seconds.

Question 12

During Start, what if 25% N2 is not possible

Answer 12

Use Max motoring guidelines and minimum 20% N2 before moving engine start lever to IDLE.

Question 13

During Start, what if 25% N2 is not possible

Question 14

Using Max motoring guideline, what is minimum N2 needed to move ESL to IDLE DETENT?

Answer 14

20% N2

Question 15

ESL to IDLE detent, what do

Answer 15

Monitor fuel flow and EGT

Question 16

Engine stable at IDLE when

Answer 16

EGT start limit redline no longer shown
