Emergency Procedures Flashcards
(57 cards)
Land immediately
Self explanatory
Land as soon as possible
Emergency conditions are urgent and require landing at the nearest landing site at which a safe landing can be made.
Land as soon as practical
Emergency conditions are less urgent and in the pilots judgement, he may proceed to the nearest airfield where he can expect appropriate assistance
Continue flight
Continue flight as planned. Repair at the destination according to the maintenance manual
Audio warning System control unit SCU
Horn push button
Used to activate audio warning
Audio warning
Gong
A gong is generated each time a red warning appears on the warning panel
Audio warning
Continuous tone
Two continuous tones can be heard:
- a 310 hz tone when Nr is below 360 rpm
- a 285 Hz tone when maximum takeoff limitations are exceeded.
- After 1.5 second delay if power remains within transient power limitations
- immediately when transient power limitations are exceeded
In addition, for VEMD after embodiment of MOD. 07-3195 only.
*Immediately when transient limitations are or will be exceeded during fast power increase
- Collective pitch - reduce to maintain NR in green arc or power within limitations
- Engine parameters - Check
Audio warning
Intermittent tone
An internment tone (310 Hz) is heard when the NR is above 410 rpm.
1. Collective pitch- increase to maintain NR in green arc. (Apply applicable procedure according to the situation)
Engine flameout (cruise flight) Autorotation procedure
Autorotation procedure over land
1. Collective pitch reduce to maintain NR in green arc
- IAS set to Vy
* If relighting impossible or after tail rotor control failure* - Twist grip idle detent
- Maneuver aircraft into wind on final approach
* At 70 ft.* - Cyclic flare
* At 20/25 ft and at consistent attitude* - Collective pitch - Gradually increase to reduce rate of descent and forward speed
- Cyclic - forward to adopt slightly nose up attitude (less than 10 degrees)
- Pedal adjust to cancel any side slip tendency
- Collective pitch - increase to cushion touchdown
* After touchdown* - Cyclic, collective, pedal - adjust to control ground run
* Once aircraft has stopped* - Collective pitch full down
- Rotor brake apply below 170 rotor rpm
Autorotation procedure over water
Apply same procedure as over land, except items 10, 11, and 12, but maneuver to head the aircraft equally between the wind and waves direction on final approach. (Ditch with IAS less than 30 kt’s) and vertical speed. Then apply following checklist items 10, 11, 12.
- After touchdown*
10. Collective pitch maintain
11. Door emergency handles pull up
12. Rotor brake apply
13. Abandon aircraft once rotor has stopped.
In-Flight relighting
According to available height and cause of flameout.
- Starting selector - off position
- [Fuel Pump] or (Fuel P) - On
- Starting selector - On position
* The relighting sequence will therefore be automatically carried out as soon as NG less than 17%*
After relighting:
- [Fuel Pump] or (Fuel P) - Off
* At least 1000’ is necessary to complete relighting procedure after flameout.*
Autorotation (hover IGE)
- Collective - maintain
- Pedals - Control yaw
- Collective increase as needed to cushion touchdown
Autorotation (hover OGE)
- Collective pitch - fully down
* When NR stops decreasing* - Cyclic - forward to gain airspeed according to available height.
- Autorotation procedure - Apply
Autorotation warning (red)
Safe autorotative landing cannot be warranted Incase of failure in HOGE below the top point of the HV diagram (refer to section 5) or in confined area
Tail rotor control failure (Symptom)
The helicopter will yaw to the left with a rotational speed depending on the amount of power and the forward speed set at time of failure.
Tail rotor control failure
Hover IGE or OGE in HV diagram
LAND IMMEDIATELY
- Twist grip - Idle detent
- Collective - increase to cushion touch-down
Tail rotor control failure
Hover OGE) (clear area, outside of HV diagram
Simultaneously
1. Collective - reduce depending on available height
- Cyclic - forward to gain speed
- Cyclic - adjust to set IAS to Vy and control yaw
Land as soon as possible
If a go around has been preformed, carry out an autorotative landing on a suitable area as landing procedure.
Tail rotor control failure
In cruise flight
- Cyclic - Adjust to set IAS to Vy and control yaw
- Collective - reduce to avoid sideslip
Land as soon as possible
Approach and landing
Carryout and autorotative landing on a suitable area as landing procedure
Smoke in cockpit/cargo area
Source not identified
Heating demisting off Smoke clears: yes continue flight (depending on weather conditions No - 1. Master switch or EMER SW - shutoff 2. (Direct batt) or (DCT BAT) - Off 3. (EXT PWR BATT) or (BAT/EPU) - Off 4. (GEN) or (GENE) - Off 5. Master avionic or avionic - Off 6. Ventilate the cabin
- when smoke clears*
1. All consumers - Off (Visually or via SCU TST)
2. (Master switch) or (EMER SW) - On
3. EXT PWR BATT or (BAT/EPU) - On Check DC parameters
4. (Direct BAT) or (DCT BAT) - On Check DC parameters
5. (GEN) or (GENE) - On Check DC parameters
If DC parameters not correct:
6. (GEN) or (GENE) - Off
7. Unnecessary equipment - Off
Land as soon as practicable
If DC parameters correct and no smoke detected:
- (Master Avionic) or (Avionic) - On
- All consumers - On, one by one to identify the failed system then keep Off.
CAUTION (AMBER)
When battery or generator are off line, the VEMD goes out and only the NR gauge remains. Apply both screen failure procedure (VEMD screen failure section 3)
Smoke in cockpit/cargo
Source Identified
- Corresponding systems - Off
- Ventilate the cabin
Continue flight depending on failed system
Note:
After DC had been switched off and on in flight, GOV light will remain on until the next normal full engine and battery switch-Off on the ground.
VEMD Screen failure (one screen)
Failed screen - Off
Read all available informations on the other screen
Informations Are available using the (Scroll) push button on either the VEMD or the collective pitch lever.
If top screen fails, the 3 parameters engine will be automatically displayed on the lower screen but with Tq and Delta (🔺)NG offline. Only T4 and digital NG will be available. Refer to 3.5.4 for compliance with limitations
VEMD Screen failure (failure of both screens)
Can be a single failure when battery and DC generator are in off position (fire and smoke detection procedure)
In this case, to avoid any power over limit, the maximum authorized power will be the power needed to establish level flight with the following law: IAS = 100 kt’s (2 kt’s/ per 1000ft hp)
Land as soon as practicable
Landing procedure: carryout no hover landing
Caution message on VEMD
When a parameter is offline, the parameter is not displayed on VEMD upper screen and the parameter scale symbology is displayed in yellow. Caution messages are self explanatory and the pilot shall comply with the action requested. If no light is lit on the caution and warning panel, no other action is required by the pilot.
Abnormal NR indication failure
Collective maintain tq greater than 10%
(NR reading given by Nf pointer
Land as soon as practicable
