Q

Tire failure during TO

A

If the decision is made to stop:
1. Abort
If TO is continued:
2. Gear and flaps position- do not change
3. Straight in approach- execute

15
Q

Maximum braking speed

A

The max speed from which the aircraft can be brought to a stop without exceeding the maximum design energy absorption capability of the brakes (3.96 million ft-lb)

16
Q

CFS and ejection procedures from the ground

A

Coordinate “CFS- rotate and pull” using internal CFS handles between front and rear cockpits

Ensure O2 mask and visor

Internal-only respective
External- both

Don’t un strap unless sure canopy is open

17
Q

PTSD INDICATIONS

A

The propeller moves toward feather due to a temporary loss of oil pressure to the propeller pitch control mechanism.
Fluctuations in Np, TQ increasing, thrust decreasing, and engine vibrations
20 sec duration
Chip detector warning

18
Q

PTSD PMU off

A

Oil pressure and volume output to the propeller pitch control increase
May be sufficient enough to overcome localized reduction in oil pressure caused by propsleve touchdown and restore propeller control

19
Q

Uncommanded changes in power/loss of power/feathering (attempted reset)

A

PCL-mid range
*midway position between idle and max
*above idle provides best chance
*minimize chances of over torque and/or over temperature
PMU- off
*itt limits potentially > 820
*increase landing distance higher N1 ~67%
If Np stable below 40%, prop SYS CB- pull
*stable: 3 sec period
*Np red Xs: PMU off then norm can reset it
*prop should unfeather 15-20 sec
PCL- as req

20
Q

Air start demands

A

~1200 feet of altitude lost
@ best glide speed of 125 kias
~ 40 sec
Below 2000 eject

21
Q

Hyd fl Lo

A

Below 1800 psi

Dropped below 1 qt

22
Q

Chip detector warning

A
  1. PCL- minimum necessary to intercept ELP; avoid unnecessary PCL movements
  2. PEL- execute
23
Q

Oil PX warning illuminates and oil pressure is normal

A

Check oil TRX CB on BAT BUS. Reset if open

24
Q

SCU failure

A

Red and Amber oil PX messages with normal oil PX indications

25
Q

Oil system malfunction or low oil PX

A

If only Amber oil PX caution illuminates:
1. Terminate maneuver
2. Check oil pressure; if oil pressure is normal, continue operations
If red oil PX warning illuminates and/or Amber oil PX caution remains illuminates for 5 secs:
3. PCL-minimum necessary to intercept ELP; avoid unnecessary PCL movements
4. PEL- execute

26
Q

NORDO

In landing pattern

A 
Check helmet connections
Check audio panel
Try other ckpt transmitter
Observe tower for ALDIS, land, and clear RW
Comply with ALDIS for return to parking
27
Q

NORDO

On course rules

A 
Check helmet connections
Check audio panel
Try other ckpt transmitter
Rock wings at break
180, check ALDIS
Land and clear RW
Taxi, with ALDIS
28
Q

NORDO

All other times

A 
Check helmet connections
Check audio panel
Try other ckpt transmitter
Overly North at 3500 msl 
Determine duty runway
PPEL to runway
Rock wings at high key
Low key, check ALDIS 
Clear runway, taxi with ALDIS
29
Q

Hydraulic system malfunctions

A 
Hyd pressure- check
Airspeed- 150 or below 
Landing gear handle- down
Flaps- extend
Land as soon as practical
30
Q

Illumination EHYD PX LO or HYD FL LO

A

May indicate a Fluid leak in either the Hyd sys

If small enough, it could bypass the Hyd fuse

May not have enough fluid to lower gear

31
Q

Loss of Hyd pressure without EHYD PX LO or HYD FL LO

A

May indicate engine-driven Hyd pump failure or partial failure

32
Q

Hyd fl LO with 0 psi Hyd PX

A

Check Hyd sys cb on batt bus

33
Q

Less 1800 psi pressure

A

Pull emergency landing gear handle for gear and flaps

Once pulled, cannot be retracted

34
Q

Safe gear down indications

A

Gear down indications in both cockpits combine to show three green lights regardless of red lights and tone

Either AOA indexer is illuminated

Landing or taxi lights are on and illuminated

Main gear are down and inboard door closed, assume nose gear down

35
Q

Functions lost with UFCP failure

A

FMS execute
System Mag/True heading toggle
System GS/CAS/TAS HUD speed toggle
Radio tuning

36
Q

EMR/NRM switch

A

In EMR position VHF audio will be unamplified and UHF audio will not be heard
