- *If ENG PWR is NOT sufficient for OEI flight: Land ASA POSSIBLE
- Then perform SE/ES
* If necessary try to escape from danger w/ both ENGs operating
* To determine if the situation will allow for OEI flight - rule of thumb - check that the sum of individual ENG TQs is lower than the OEI TQ limit
15
Q
Land Immediately
A
The urgency of the landing is paramount. Primary considerations is to assure survival of the occupants. Landing in water, trees or other unsafe areas should be considered only as a last resort.
16
Q
Land as soon as POSSIBLE
A
Land w/out delay at the nearest adequate site (i.e. open field) at which a safe approach and landing can be made.
17
Q
Land as soon as practical
A
The landing site and duration of flight are at the discretion of the pilot. Extended flight beyond the nearest approved landing area where appropriate assistance can be expected is not recommended.
18
Q
Resetting tripped Circuit Breakers
A
A tripped CB shall not be reset In-Flight unless doing so is consistent with EP. No attempt should be made to reset a CB if it trips a second time.

PPC Rules of Thumb
```
Lbs to Kgs = 2.205
Zero fuel wt = (-) 1534 lbs
Low fuel = 24kgs / 53lbs
1% TQ = 90 lbs
1% TQ = (0-20c)
1% TQ = (20-40c)
2% TQ = 1000 PA
1% TQ = (5kts wind)
3% TQ = (6-10kts wind)
7% TQ = (>10kts wind)
7% TQ = (IGE - OGE)
```
VARTOMS: <55kts = 96.5 - 102 Nr
VARTOMS: >_55kts = 101 - 103.5 Nr
Charts that apply to "OEI" conditions are marked on the upper corner with a black color triangle
67
When must a PPC be recomputed?
Increase of:
+5c
+500ft PA
+200lbs wt
68
How do you convert Kg to lbs for PPC Gross Weight?
Use multiplier x 2.205
| example: 3585kg x 2.205 = 7905 lbs
69
Max PA & Max Temp will be used for all computations EXCEPT?
Go NO/GO Torque
| Predicted Hover TQ
70
How is Zero Fuel Wt computed on PPC?
Total Fuel is (112.3 gals).
Total Fuel Wt is 1530 lbs
*Subtract 1530 lbs from Aircraft GWT - Block (1) and enter into Zero Fuel Wt - Block (4)
71
Why should you be concerned if Max TQ Avail AEO is above/below 97% TQ?
This number will allow you to know ahead-of-time (if) the Aircraft is capable of achieving Max TQ (AEO) - I/A/W Operator's Sup Max TQ AEO (88% for 5 min or 97% for 12 sec)
72
When computing GO NO/GO TQ (IGE/OGE) should you use Max or current Temp/PA?
Must use current Temp and PA
73
During hover pwr check if "3ft hover TQ" is above or below GO NO/GO (IGE) TQ, what does that mean for you?
If above GO NO/GO (IGE) TQ: over Max GWT
If below GO NO/GO (IGE) TQ: below Mx GWT
If above GO NO/GO (OGE) TQ: aircraft is to heavy to perform OGE
74
What is the significance of knowing Max GWT OGE w/ MCP?
If the actual Aircraft GWT is above this weight you can expect to be in the 5 min PWR T/O range (>8.5 FLI) while performing OGE maneuvers. (1% TQ = approx, 90 lbs)
75
What is the significance of knowing the H/V Altitude (AGL)?
```
Hovering OGE (w/ zero airspeed) at or above this ALT a safe landing can be expected after SEF.
Hovering OGE (w/ zero airspeed) below this ALT a safe landing may not be possible after a SEF. Avoid or stay minimum time.
(drawing a boundary curve on the HV diagram will reveal varying airspeed and altitude combinations from which a safe landing can be expected after a SEF and help determine areas that should be avoided if possible.
```
76
Cruise Data on PPC:
| What A/S and TQ will you use to stay on station as long as possible?
use Max Endurance Arirpeed and Max Endurance TQ
77
What A/S and TQ will you use to climb as fast as possible?
Use Max TQ Avail (AEO): Red line - TQ = 88% / FLI = 10 (5 min)
Use A/S between 45kts (Vx) and 65kts (Vy) for best climb (A/S>65kts = over TQ)
78
What is the significance of "OEI IAS - MIN/MAX"?
the Min A/S number should = 12 FLI (Max TQ 2.5 min)
When doing Practice SELs (OEI) attempting to land at Min A/S with Max FLI - this recorded A/S should be close to your touchdown speed.
the Max A/S nuber should = 12 FLI, (Max TQ 2.5 min)
This recorded A/S is your Max OEI IAS you can expect at 12 FLI.
(Remember: Vne for OEI flight is limited to 110kts)
79
When does "Arrival Data" have to be computed?
```
Must be computed if there is an increase of:
+5c
+500ft PA
+200 lbs
Between departure and landing locations
```
80
What Publications are required for flight?

Inadvertant IMC Procedures
Pilot on the Controls:
A - Announce IMC: (maintain a/c control, transition to ins., initiate climb)
A - Attitude: Level the wings on Att Ind.
H - Heading: maintain heading, turn only to avoid known obstacles
T - TQ: Adjust TQ as necessary
T - Trim: Trim a/c as necessary
A - A/S: Adjust a/s as necessary
A - Altitude: Adjust to desired alt after estab a/c control
Pilot not on the Controls:
will monitor the cockpit instr. to assist in recovery, adjust transponder to emergency, tune radios, make approp. radio calls and perform other tasks as directed by the PC.
The most important action is to climb while estab. a/c control
The crew brief states local area specifics.
ATM states: Level Att, 65kts, Positive RoC, then complete IMC Procedurs
WARNING: do NOT use upper modes until a/c is under control.
83
What is the Weight & Balance Classification of the UH-72?

How is stabilization of the aircraft from random P/R/Y excursions caused by wind and turbulence through what systems?
AFCS Auto-Pilot / Upper Modes, provide a high degree of stabilization through fiber optic gyros (FOG), computers, and magnetometers, SEMA's and SAS systems enabling "Hands-Off" flight and even full autopilot w/ navigation.
129
The basic function of AFCS/Autopilot is accomplished by using a mix of:
Sensors: OAT, FOG, magnetometers, air data computer (ADC), records changes in attitude P/R/Y and sends data to the "Brains"
Brains: 2 ea. Autopilot Modules (APM), 2 ea. Attitude & Hold Reference Systems (AHRS) which interpret and then calculate from aircraft sensors, a response to the movements of the aircraft through the use of systems "Muscles"
Muscles: Hyd assist - 5 ea. SEMA's and SAS
130
What are the 5 levels of Stabilization?
1. Unstabilized: no AFCS and No autopilot
2. Back-up SAS: Only SAS actuators ON
3. Digital SAS: Autopilot On / Trim motor (s) Off

| - only basic force trim (FTR) is avail.
132
What is level 2 of Stabilization?
Back-Up SAS: Use SAS On (cyclic)
- both autopilots off
- uses FOGs as sensors in P/R/Y axis (brains)

- uses duplex SEMSs as actuators in P/R axis and single SEMA in Y axis (muscles)
* all 5 SEMAs / FOG's and FTR are avail*
134
what is level 4 of Stabilization?
Basic Autopilot: Attitude hold. provides stable platform for upper modes:
- both autopilots on, cyclic & yaw trim motors on, NO upper modes engaged
- uses AHRS in P/R/Y axes
- uses duplex SEMA in P/R and single SEMA in Y axes controlled by APM
* Autopilots engaged, all 5 SEMAs / FOG's and FTR avail.*
- FTR switch releases cyclic control forces
- BEEP TRIM moves P attitude 2deg/sec for and aft, and roll attitude 4deg/sec laterally
- left/right pedal temporarily overrides Y trim
135
What is level 5 of Stabilization?
Auto Pilot Upper Modes: Upper modes ops provide the following:
