Flashcards in Chapter 9 (change 8) Deck (74):
1

LAND AS SOON AS POSSIBLE

 

LAND AS SOON AS PRACTICABLE

a. 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.)

b. 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.)

2

AUTOROTATE (definition)

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

3

EMER ENG SHUTDOWN(DEFINITION AND PROCEDURE)

1. ENG POWER CONT lever(s) - OFF

2. ENG FUEL SYS selector(s) - OFF

3. FUEL BOOST PUMP CONTROL switch(es) - OFF

  If TGT is over 538ºC after shutdown

4. AIR SOURCE HEAT/START switch - As requred

5. ENGINE IGNITION switch - OFF

6. Starter button - Press to motor engine for 30 seconds or until TGT TEMP decreases below 538ºC.

4

LOCKOUT

(definition, warning, caution, procedure)

The term LOCKOUT is defined as manual control of engine RPM while bypassing ECU, or DEC functions (700ECU)(701C/D/CC EDECU)

WARNING

 Going to ECU/DEC/EDECU LOCKOUT to obtain additional power does not remove Maximum Fuel Flow or Ng limits. % RPM R 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 % RPM 1 and 2 in operating range.Procedure: ENG POWER CONT lever - Pull down and advance full forward while maintaining downward pressure, then adjust to set %RPM R as required.

5

EMER APU START (definition, procedure, caution)

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

1. FUEL PUMP switch - APU BOOST

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.

2. APU CONTR switch - ON

6

ENGINE MALFUNCTION - PARTIAL OR COMPLETE POWER LOSS-(WARNING)(WARNING)

WARNING

  • Single engine capability must be considered prior to movement of the engine power control lever. Prior to movement of either PCL, it is imparative that the malfunctioning eng and the corresponding PCL be identified. If the decision is made to shut down an engine, take at least 5 full seconds while retarding the ENG POWER CONT lever from FLY to IDLE, monitoring % TRQ, Ng SPEED, TGT, %RPM, and ENG OUT warning appearance.

 

  • Significant rotor drop that results in the generators dropping off line or a dual generator or converter failure will result in a partial power loss. This power loss will be due to the opening of engine antiice valves and will result in a further reduction of max Q available by18% for the 701D Engine

7

SINGLE ENGINE FAILURE (WARNING)(WARNING)

 1. Collective - Adjust to maintain % RPM R.

②. External cargo/stores - Jettison (if required).

 3. Establish single-engine airspeed.

  If continued flight is not possible:

 4. LAND AS SOON AS POSSIBLE 

  If continued flight is possible:

 5. LAND AS SOON AS PRACTIABLE.

WARNING

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 and cockpit heater should be turned off as necessary to ensure maximum power is available on the remaining engine.

WARNING

Do not repsond to ENG OUT warning and audio until checking TGT, Ng, and % RPM 1 and 2.

8

DUAL ENGINE FAILURE

(PROCEDURE, WARNING AND STEADY STATE FACTORS)

AUTOROTATE.

WARNING

Do not respond to ENG OUT warnings and audio until checking TGT TEMP and % RPM R.

STEADY STATE FACTORS

  • ROTOR within limits
  • AIRSPEED above 80 KIAS
  • TORQUE
  • TRIM
  • SAFE, Aircraft in a position to land at desired touchdown point.

 4. LAND AS SOON AS PRACTICABLE.

WARNING

GOING TO ECU/EDECU LOCKOUT to obtain additional power does not remove Maximum Fuel Flow or Ng limits. % RPM R will decrease below normal operating range if Maximum Fuel Flow or Ng limits are exceeded.

CAUTION

When eng is controlled with ENG POWER CONT lever in LOCKOUT, engine response is much faster and the TGT limiting system is inop. Care must be taken not to exceed TGT limits and keeping % RPM R and % RPM 1 and 2 in operating range.

NOTE

(abbreviated) If %RPM R reduces from 100% to 95-96% in steady flight and %TRQ 1/2 are equal below max Q avail, attempt to use ENG RPM trim sw.

10

Increasing % RPM R

"ELEPR"

ENG POWER CONT lever (high % TRQ/TGT engine) - Retard. Maintain % TRQ appx 10% below other eng.

 2. LAND AS SOON AS PRACTICABLE

     If the effected engine does not respond to ENG POWER CONT lever movement in the range between FLY and IDLE, the HMU may be malfunctioning internally.
