Chapter 9 (change 8) Underlined ONLY Flashcards
LAND AS SOON AS POSSIBLE
landing at the nearest suitable landing area (e.g., open field) without delay. (The primary consideration is to ensure the survival of occupants.)
LAND AS SOON AS PRACTICABLE
Landing at a suitable landing area. (The primary consideration is the urgency of the emergency.)
Autorotate
adjusting the flight controls as necessary to establish an autorotational descent and landing.
EMER ENG SHUTDOWN
Engine shutdown without delay.
- ENG POWER CONT lever(s) - OFF
- ENG FUEL SYS selector(s) - OFF
- FUEL BOOST PUMP CONTROL switch(es) - OFF
If TGT is over 538ºC after shutdown
- AIR SOURCE HEAT/START switch - As requred
- ENGINE IGNITION switch - OFF
- Starter button - Press to motor engine for 30 seconds or until TGT TEMP decreases below 538ºC.
LOCKOUT
manual control of engine RPM while bypassing 700 ECU, or 701C/701D/CC DEC/EDECU functions.
- ENG POWER CONT lever - Pull down and advance full forward while maintaining downward pressure, then adjust to set %RPM R as required.
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.
EMER APU START
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
1 or #2 FUEL PRESS Caution Appears (critical)
① ENG FUEL SYS selector on affected engine XFD.
② FUEL BOOST PUMP CONTROL switches - NO. 1 PUMP or NO. 2 PUMP - ON (As applicable).
- LAND AS SOON AS POSSIBLE.
④ EMER ENG SHUTDOWN after landing.
b. Non-critical situations are those where single engine flight is possible.
① ENG FUEL SYS selector on affected engine XFD.
② FUEL BOOST PUMP CONTROL switches NO. 1 PUMP or NO. 2 PUMP - OFF (As applicable).
- LAND AS SOON AS PRACTICABLE.
FLIGHT CONTROL/MAIN ROTOR SYSTEM MALFUNCTIONS
- LAND AS SOON AS POSSIBLE.
② EMER ENG(S) SHUTDOWN after landing.
Emergency Landing In Wooded Areas - Power Off.
- AUTOROTATE. Decelerate helicopter to stop all forward speed at treetop level.2. Collective adjust to maximum before main rotor contacts tree branches.
Collective Boost Servo Hardover/Power Piston Failure
① BOOST switch - Off.2. LAND AS SOON AS PRACTICABLE. Hardover failure of the collective boost servo will increase control forces (as much as 150 pounds) in the collective.
Main Transmission Failure
- Collective - Adjust only enough to begin a descent with power remaining applied to the main transmission throughout the descent and landing.2. LAND AS SOON AS POSSIBLE.
APU OIL TEMP HI Caution Appears
APU CONTR switch - OFF. Do not attemptrestart until oil level has been checked.
Compressor Stall
- Collective - Reduce. If condition persists:② ENG POWER CONT lever (affected engine) Retard (TGT TEMP should decrease).③ ENG POWER CONT lever (affected engine) FLY. If stall condition recurs:4. Establish single engine airspeed.⑤ EMER ENG SHUTDOWN (affected engine).⑥ Refer to single-engine failure emergency procedure.
Loss of Tail Rotor Thrust or TAIL ROTOR QUADRANT Caution Appears with Loss of Control at Low Airspeed/Hover (Right Rotation)
- Collective - Reduce.② ENG POWER CONT levers - OFF (5 to 10 feet above touchdown).
1 and #2 HYD PUMP Cautions Appear
LAND AS SOON AS POSSIBLE. Restrict control movement to moderate rates.
1 and 2 FUEL FLTR BYPASS Cautions Appear
LAND AS SOON AS POSSIBLE
EMERGENCY RELEASE OF RESCUE HOIST LOAD
If the rescue hoist becomes jammed, inoperative, or thecable is entangled and emergency release is required: To cut cable from cockpit:CABLE SHEAR switch - FIRE. To cut cable from hoist operator’s position:CABLE CUT switch - FIRE
DECREASING RPM R(PROCEDURE, WARNING, CAUTION, NOTE)
- Collective - Adjust to control % RPM R.2. Establish single-engine airspeed.③ ENG POWER CONT lever (low % TRQ/TGT TEMP engine) - LOCKOUT. Maintain % TRQ appx 10% below other eng.4. LAND AS SOON AS PRACTICABLEWARNING: 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.”CEEL”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.
1 or #2 FUEL FLTR BYPASS Caution Appears
① ENG FUEL SYS selector on affected engine - XFD.2. LAND AS SOON AS PRACTICABLE.
Ditching - Power Off
- AUTOROTATE.2. Cockpit doors jettison and cabin doors openprior to entering water.3. Apply full collective to decay rotor RPM ashelicopter settles.4. Position cyclic in direction of roll.5. Exit when main rotor has stopped.
1/2 FUEL PRESS Cautions Appear
- LAND AS SOON AS POSSIBLE.② EMER ENG SHUTDOWN after landing.
Pedal Bind/Restriction or Drive With No Accompanying Caution
- Apply pedal force to oppose the drive.② Check other pedals for proper operation.③ TAIL SERVO switch - BACKUP. If normal control authority is not restored:④ TAIL SERVO switch - NORMAL.⑤ BOOST switch - OFF. If normal control forces are not restored:⑥ BOOST switch - ON.7. Collective - Adjust to determine controllabilityfor landing.8. LAND AS SOON AS PRACTICABLE.
MR DE-ICE FAULT, MR DE-ICE FAIL, or TRDE-ICE FAIL Caution Appears
- Icing conditions - Exit.② BLADE DE-ICE POWER switch - OFF, when out of icing conditions.If vibrations increase:3. LAND AS SOON AS POSSIBLE
