EP/NATOPs QUESTIONS AND ANSWERS
LATEST UPDATED
01 Abort Start Procedure - Reasons the PMU would abort a battery start
attempt
-Weak battery
-High OAT
-High pre-start ITT
-High-density altitude
-Tailwind
They cause a rate of rise in N1 and/or ITT that are indicative of an
impending hung or hot start.
NATOPS: 01. What is lost if the ST READY light extinguishes during
start?
The PMU will no longer provide automatic protection. Any time this
occurs, including after the PCL has been advanced past the auto start
position, the PMU will not cut off fuel to terminate a start.
Start must be manually aborted.
PCL - OFF or STARTER SWITCH - AUTO/RESET
Either action resets the PMU and aborts the autostart.
02 Emergency Engine Shutdown on the Ground
1. PCL - OFF
2. FIREWALL SHUTOFF HANDLE - PULL
3. Emergency ground egress - As required
In the event of an 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.
NATOPS: 02. What causes a CHK ENG caution (AMBER) message to
illuminate?
, NATOPS: 02. What causes the CHK ENG warning (RED) message to
illuminate?
03 Emergency Ground Egress
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 safety pin - Remove (BOTH)
6. CFS handle - Rotate 90° counterclockwise and pull (BOTH)
7. Upper fittings, lower fittings, and leg restraint garters - Release
(BOTH)
8. BAT, GEN, and AUX BAT switches - OFF
9. Evacuate aircraft
03 Emergency Ground Egress (N/W/C's)
N1: In a situation requiring immediate ground egress, the ejection
system has the capability for 0/0 ejection.
W1: Failure to ensure that the ISS mode selector is set to SOLO may
result in the inadvertent ejection of one or both seats.
W2: Failure to insert both ejection seat safety pins (if occupied) before
ground egress may result in inadvertent activation of ejection sequence
and subsequent injury or death when performing emergency ground
egress.
W3: If the canopy fracturing system malfunctions in conjunction with a
canopy latch failure in the locked position, ejection may be the only
option remaining to exit the aircraft. Aircrew shall remove the ejection
