Ground Emergencies

Question 1

Abort Start Procedures

Answer 1

In the AUTO start mode, if a no start is detected or if a hung
or hot start is projected, the PMU should terminate the start
sequence. However, the engine start should be aborted manually in the following situations

Question 2

Manual Abort Start situations

Answer 2

• ITT rate of increase appears likely to exceed 1000 °C
(hot start) tell maintenance time and degree of overtemp
• Normal N1 increase is halted (hung start)
• No rise of ITT is evident within 10 seconds after fuel
fuel flow indications (no start)
• BAT BUS annunciator illuminates during the start
sequence
• PCL is moved or the ST READY annunciator extinguishes during the start sequence

Question 3

If start is initiated with PCL in OFF position, how do you abort?

Answer 3

select auto/reset on STARTER switch

Question 4

If start is initiated with PCL out of OFF but not past IDLE gate, how do you abort?

Answer 4

either select auto/reset or bring PCL bank to OFF

Question 5

If start is initiated with PCL past IDLE gate, how do you abort?

Answer 5

bring the PCL back to off

Question 6

Cautions with Motoring Run Procedure

Answer 6

• if start used external power is aborted (PMU or manual) do not attempt subsequent starts
• Repeated PMU aborted starts attempts are indicative of engine malfunction

Question 7

During ground starts, what parameters could cause the PMU to abort?

Answer 7

weak battery, high OAT, high pre-start ITT, high density altitude, tailwind

Question 8

If battery start is aborted (PMU/manual) do you connect external power?

Answer 8

Yes, and attempt restart if no engine malfunctions are evident and no limits exceeded

Question 9

Motoring Run Procedure

Answer 9

Perform after an aborted start, to clear engine of residual fuel/ lower ITT

1. PCL - OFF
2. IGNITION switch - NORM
3. Propeller area - Clear
4. STARTER switch-MANUAL for 20 seconds
5. STARTER switch - NORM

Question 10

Is the starter switch spring loaded from manual to norm?

Answer 10

No

Question 11

Motor Run starter delay cycle to cool engine

Answer 11

30 sec, 2 min, 5 min, 30 min

Question 12

FIRE WARNING ON GROUND

Answer 12

• Primary indication is FIRE light with MASTER WARNING with other indications (visual, high ITT, Fluctuating/ high fuel flow)
• Any indication of FIRE shutdown, Emergency ground egress

Question 13

EMERGENCY ENGINE SHUTDOWN ON THE

GROUND

Answer 13

• 1. PCL - OFF
• 2. FIREWALL SHUTOFF HANDLE - PULL
• 3. Emergency ground egress - As required

Question 14

5 situations to EMERGENCY ENGINE SHUTDOWN ON THE GROUND

Answer 14

engine fire, prop strike, or chip light; if the aircraft appears likely to depart the prepared surface; or should any other serious ground emergency occur

Question 15

EMERGENCY GROUND EGRESS

Answer 15

1. ISS mode selector – SOLO
2. Seat safety pin – Install (BOTH)
3. PARKING BRAKE – As required
4. Canopy – Open
   IF CANOPY CANNOT BE OPENED OR SITUATION
   REQUIRES RIGHT SIDE EGRESS:
5. CFS handle – Rotate and pull (BOTH)
6. Release restraints
7. BAT, GEN, and AUX BAT switches – OFF
8. Evacuate aircraft

Question 16

Why confirm ISS SOLO during Emergency ground egress?

Answer 16

could lead to inadvertent ejection of one or both seats

Question 17

Why confirm ejection pin being in?

Answer 17

during egress inadvertent activation of handle could lead to ejection seat activating leading to serious injury/ death

Question 18

If canopy can’t open CFS system fails in Emergency ground egress fails?

Answer 18

Ejection is only option, assume body position.

Question 19

How to prevent injury if using CFS?

Answer 19

ensure O2 mask is on and visor down

Question 20

TAKEOFF EMERGENCIES decision factors

Answer 20

● Runway length and condition, terminal weather conditions and area traffic.
● If any system emergency affecting safety of flight is
experienced prior to liftoff, the takeoff should be aborted.

Question 21

ABORT

Answer 21

• 1. PCL – IDLE

* 2. BRAKES – AS REQUIRED

Question 22

After Max braking following an Abort, what are the considerations

Answer 22

Hot brakes could occur from max braking, don’t taxi or park in congested areas until brakes cool, DON’T set parking brake

Question 23

BARRIER ENGAGEMENT

Answer 23

Don’t call to raise barriers and steer around it, to include departing prepared surface or ejection before entering barrier (so to speak)

Question 24

Warnings with Barriers

Answer 24

• Significant aircraft damage can be anticipated when engaging a raised web barrier and webbing may preclude normal canopy opening.
• If contact with a lowered BAK-15 is imminent, discontinue braking before reaching lowered barrier, then recommence once past
  barrier. In the unlikely event that webbing catches on aircraft, there may be unexpected directional control problems.

Question 25

AIRCRAFT DEPARTS PREPARED SURFACE

Answer 25

If it appears likely that the aircraft will depart the prepared surface, execute the Emergency Engine Shutdown On The Ground procedure.

Question 26

TIRE FAILURE DURING TAKEOFF

Answer 26

IF THE DECISION IS MADE TO STOP: 1. Abort
IF TAKEOFF IS CONTINUED:
2. Gear and flaps position – Do not change
3. Straight-in approach–Execute

Question 27

How should you land following a Tire Failure?

Answer 27

Land on side of runway corresponding to the good tire (put drag in the middle). Maintain directional control using rudder, brakes, and nose wheel steering as required.

Question 28

ENGINE FAILURE IMMEDIATELY AFTER TAKEOFF (SUFFICIENT RUNWAY REMAINING STRAIGHT AHEAD)

Answer 28

• 1. AIRSPEED – 110 KNOTS (MINIMUM)
• 2. PCL – AS REQUIRED
• 3. EMER LDG GR HANDLE – PULL (AS REQUIRED)
• 4. Flaps – As required
