UH-60M - Emer. Proc. (ch. 9)

Question 1

The term LAND AS SOON AS POSSIBLE is defined as ___

Answer 1

The term LAND AS SOON AS POSSIBLE is defined as landing at the nearest suitable landing area (e.g., open field) without delay. (The primary consideration is to ensure the survival of occupants.)

Question 2

The term LAND AS SOON AS PRACTICABLE is defined as ___

Answer 2

The term LAND AS SOON AS PRACTICABLE
is defined as landing at a suitable landing area.
(The primary consideration is the urgency of the emergency.)

Question 3

The term AUTOROTATE is defined as __

Answer 3

The term AUTOROTATE is defined as adjusting the flight controls as necessary to establish an autorotational descent and landing.

Question 4

The term EMER ENG SHUTDOWN is defined as __

EP:

1. ____________________
2. ____________________
3. ____________________

CAUTION:
​If TGT rises above 500°C after shutdown, place AIR SCE HT/START switch as required, turn ENGINE IGNITION switch OFF, and press starter to motor engine for 30 seconds or until TGT decreases below 500°C.

Answer 4

The term EMER ENG SHUTDOWN is defined as engine shutdown without delay.

EP:

1. EPCL(s) - OFF.
2. ENG FUEL SYS selector(s) - OFF.
3. FUEL BOOST PUMP CONTROL switch(es) - OFF.
   If TGT rises above 500°C after shutdown:
4. AIR SOURCE HEAT/START switch - As required.
5. ENGINE IGNITION switch - OFF.
6. Starter button - Press to motor engine for 30 seconds or until TGT TEMP decreases below 500°C.

Engine shutdown in flight is usually not an immediate action item unless a fire exists.

Before attempting an engine shutdown, identify the affected engine by checking ENG OUT warning lights, NP, NR, Q (torque), P (engine oil pressure), TGT, and NG.

Question 5

The term LOCKOUT is defined as _____

EP:

___________________

Answer 5

The term LOCKOUT is defined as manual control of engine RPM while bypassing DEC functions.

EP:

ENG POWER CONT LEVER - Pull down and advance full
forward while maintaining downward pressure,
then adjust to set NR as required.

Bypass of the engine control will be required when NP 1 or 2 decreases below normal demand speed due to a malfunction of the ECU/DEC/EDECU.

Warning - Going to DEC/EDECU LOCKOUT to obtain additional power does not remove Maximum Fuel Flow or NG limits. NR will decrease below normal operating range if Maximum Fuel Flow or NG limits are exceeded.

Caution - When engine is controlled with ENG POWER CONT lever in LOCKOUT, engine response is much faster and TGT limiting system is inoperative. Care must be taken not to exceed TGT limits and keeping NR and NP 1 and 2 in operating range.

Question 6

The term EMER APU START is defined as ____

EP:

1. ______________\_
2. ______________\_

Answer 6

The term EMER APU START is defined as APU start to accomplish an emergency procedure.

EP:

(1. ) FUEL PUMP switch - APU BOOST.
(2. ) APU CONTR switch - ON.

Caution - Ensure that the mask blowers are disconnected and position the BCA MCU control knobs to OFF prior to switching from main power to APU power.

Question 7

SINGLE ENGINE FAILURE

1. _______________________
2. _______________________
3. _______________________

If continued flight is not possible:
4. _______________________

If continued flight is possible:
​5. LAND AS SOON AS PRACTICABLE

Answer 7

1. Collective - Adjust to maintain NR
   (2. ) External cargo/stores - Jettison (if required).
2. Establish single-engine airspeed.

If continued flight is not possible:
4. LAND ASAP.

If continued flight is possible:
5. LAND AS SOON AS PRACTICABLE

WARNING -

Do not respond to ENG OUT warning and audio until checking TGT, NG, and NP1 and NP2.

When the power available during single engine operation is marginal or less, consideration should be given to jettisoning the external stores. The engine anti-ice, heater switch, HH−60M OBOGS, and ECS switches should be turned off as necessary to ensure maximum power is available on the remaining engine.

Question 8

DUAL ENGINE FAILURE

1. ______________________

Answer 8

1. AUTOROTATE

WARNING - Do not respond to ENG OUT warning lights and audio until checking TGT and NR.

(2) . ______________________
3. LAND AS SOON AS PRACTICABLE

Answer 9

1. Collective - Adjust to control NR.
2. 1. Establish single-engine airspeed.

If single engine flight cannot be achieved or maintained:

(2.) EPCL (low Q/TGT TEMP engine) - LOCKOUT.
Maintain Q approximately 10% below other engine.
3. LAND AS SOON AS PRACTICABLE

WARNING - Going to DEC LOCKOUT to obtain ad- ditional power does not remove Maxi- mum Fuel Flow or NG limits. NR may still decrease below normal operating range if Maximum Fuel Flow or NG limits are reached.

CAUTION - When engine is controlled with ENG POWER CONT lever in LOCKOUT, engine response is much faster and the TGT limiting system is inoperative. Care must be taken not to exceed TGT limits and keeping NR, NP1 and NP2 in operating range.

NOTE - If NR reduces from 100% to 95-96% during steady flight, check Q1 and Q2. If Q1 and Q2 are equal and below Maximum Torque Available, attempt to increase NR with ENG SPD TRIM switch.

Question 10

1. _________________________\_
   ​2. _________________________\_

Answer 15

(1. ) EPCls - Adjust (as required to control NP and NR).
2. LAND ASAP.

WARNING - Lightning strikes may result in loss of automatic flight control functions, engine controls, and/or electric power.
Lightning strike may cause one or both engines to immediately produce maximum power with no TGT limiting or overspeed protection. Systems instruments may also be inoperative. If this occurs, the flight crew would have to adjust to the malfunctioning engine(s) ENG POWER CONT lever(s) as required to control NP and NR by sound and feel. If practical, the pilot should reduce speed to 80 KIAS. This will reduce the criticality of having exactly correct rotor speed 100%.
