This is intended to introduce the associated material and all persons using these cards should study and reference the officially distributed material from the manufacturer. It is recommended that after referencing each card, the student should independently verify the information on that card by looking it up and learning the comprehensive information from the direct source. If any inaccuracies, misleading or typo errors are found, please notify the administrator of the study deck.
SMOKE IN CABIN
Source Not Identified
- Heating/Demisting OFF
- Electrical Master ALL OFF
- When smoke gone, set all switches to OFF (including generator), close vents
- Reset battery to ON
- Reset ALL OFF to normal
- Switch on Generator and check voltage and current
- If normal, switch on systems one by one until malfunctioning system identified
ON VEMD
When switching Electrical Master off/Emer Shed, you will lose both VEMD and may have a governor light. During the time the screens are off apply SCREEN FAILURE EP (Slow to 100kias -2kias per 1000hp). Once Master/Emer Shed is turned back on, battery back on Gen on, make sure VEMD are turned back on and then check DC parameters to assure Gen is working. If normal, complete above procedures.
On both versions if GEN does not come back on line, LAND AS SOON AS PRACTICABLE, turn off all unnecessary equip to conserve battery. Review loss of Gen EP.
SMOKE IN CABIN
Source Identified
- Shut off identified system
- If necessary use fire extinguisher
- Air cabin by opening front vent, vent ports, window
RELIGHTING ENGINE IN FLIGHT
(Usually above 13000 feet)
- -PUMPS ON
- -GENERATOR ON
- -Wait Until NG Below 30% Then Carry Out Normal Startinting Procedure
(In order to avoid jerk on re-synchronization, accelerate the engine progressively when NF approaches NR)
ABNORMAL NR/NF READINGS
If NR/NF Values Agree
NR/NF below green arc, if the values agree
Excessive power demand: Reduce collective pitch. Indicator values should rise to governed value.
Governor failure, use Gov. Failure EP
TAIL ROTOR FAILURE
In Forward Flight
Reduce power as much as possible, maintain forward speed (weathercock effect), select suitable landing area for steep approach with power setting for reasonably coordinated flight
On final, shut down engine, autorotate, touch down at lowest possible speed
HIGH ENGINE OIL TEMP
In Cruise Flight
Reduce power and set speed at 80 knots.
Temperature should fall rapidly
If not, LAND AS SOON AS POSSIBLE
FLAME OUT IN FLIGHT
SYMPTOMS
- Jerk in Yaw Axis (only in high power flight)
- Drop in Rotor RPM (Horn below 360 RPM)
- Torque at Zero
- NG Falling to Zero
- Generator Warning Light ON
- Engine Oil Pressure Warning Light ON
- ENTER AUTOROTATION!!
IN FLIGHT
Analog AStar
Reduce power
Monitor MGB P and MGB T lights, if either of those should come on perform those EP
VEMD SHIP
LAND AS SOON AS POSSIBLE
IN FLIGHT
- Test DC voltage
- Check to make sure GEN button in
- Attempt GEN RESET, if unsuccessful: Shed the least essential consumers. CONTINUE FLIGHT, watch voltage (22V minimum)
The following old EP has been deleted, but included here as a guide for battery time that MAY remain if GEN lost. Battery may fail unexpectedly if there is no GEN.
- Maximum flight time on battery: 50 minutes day, 20 minutes night
LAND AS SOON AS PRACTICABLE
Observe altitude limits if turning off booster pumps
IN FLIGHT
Disconnected in SDH ships. If illuminated, possible wire short should be investigated.
Normal EP is:
Isolate the battery (pushbutton OFF)
LAND AS SOON AS POSSIBLE
T4 INDICATOR FAILURE
Comply with NG limitations
DO NOT attempt to restart engine
GOVERNOR FAILURE
Excessive Fuel Flow Rate
NG, T4, NR, and Torque increase
- Do NOT reduce collective
- Reduce FFCL until rotor RPM in safe green arc
- Continue flight with the governor out. Any reduction of collective will cause rise in rotor RPM, which must be counteracted by reducing FFCL
- Shallow approach, 65 Knots
- Control rotor RPM 394 with FFCL
- On final slow without adjusting FFCL
- Rotor RPM will slow as collective raised for touchdown
- After TD reduce FFCL BEFORE reducing collective.
LOW ENGINE OIL PRESSURE
Oil pressure gauge in lower RED arc with NG above 85%
VEMD
- Test Warning-Caution Panel and check that ENP P light illuminates
- If ENG P light is already on, or does not illuminate when tested (presume it is on):
- LAND IMMEDIATELY: Autoration precedures apply; Shut down engine time permitting
- If ENG P light does illuminate when tested:
- LAND AS SOON AS PRACTICABLE.
- Monitor ENG P light
ANALOG
- Test Warning-Caution Panel and check that ENP P light illuminates
- If ENG P light does not illuminate when tested:
- If torquemeter is much too low, SHUT DOWN ENGINE and AUTOROTATE
- If ENG P light does illuminate when tested:
- But torquemeter is too low, LAND AS SOON AS POSSIBLE
- If torquemeter is correct, LAND AS SOON AS PRACTICABLE.
- Monitor ENG P light
NR (ROTOR RPM) INDICATOR FAILURE
Maintain engine torque above 10%: NR reading is then given by the NF pointer
LAND AS SOON AS PRACTICABLE
BLEED VALVE ON NG INDICATOR
When bleed valve closes, flag disappears (normally open when shutdown, and during start procedure and low power)
If flag is on above specified range your maximum available engine power is reduced (especially in cold weather)
If flag doesn’t come on below specified range engine surging may result. Avoid sudden power variations
Push horn button ON
Check that battery button is ON
Watch voltage (minimum 22V)
CONTINUE FLIGHT
VEMD SCREEN FAILURES
FAILURE OF ONE SCREEN
Turn failed screen OFF. Read all available data on the remaining screen
Data is available using the SCROLL button either on VEMD or the collective.
FAILURE OF BOTH SCREENS
Can be a single failure when BAT/EPU and GENE or EMER SW (fire and smoke detection procedure) are in OFF position.
- To avoid power overlimit*
- Reduce power limit to 100 kts - 2 kt per 1000 ft Hp*
LAND AS SOON AS PRACTICABLE
Carry out a no hover landing
IN FLIGHT
Analog:
Reduce engine power
If light goes out
CONTINUE FLIGHT at reduced power
If remains on
LAND AS SOON AS POSSIBLE
VEMD:
Reduce Engine Power
If light goes out
LAND AS SOON AS PRACTICABLE
If light stay on
LAND AS SOON AS POSSIBLE
If experiencing NG oscillations
LAND IMMEDIATELY
(Autorotation procedures apply)
