Flashcards in Emergency Procedures Deck (57):

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

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

1. Collective pitch - reduce to maintain NR in green arc or power within limitations
2. 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

2. IAS set to Vy

*If relighting impossible or after tail rotor control failure*

3. Twist grip idle detent

4. Maneuver aircraft into wind on final approach

*At 70 ft.*

5. Cyclic flare

*At 20/25 ft and at consistent attitude*

6. Collective pitch - Gradually increase to reduce rate of descent and forward speed

7. Cyclic - forward to adopt slightly nose up attitude (less than 10 degrees)

8. Pedal adjust to cancel any side slip tendency

9. Collective pitch - increase to cushion touchdown

*After touchdown*

10. Cyclic, collective, pedal - adjust to control ground run

*Once aircraft has stopped*

11. Collective pitch full down

12. 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

In-Flight relighting

According to available height and cause of flameout.

1. Starting selector - off position

2. [Fuel Pump] or (Fuel P) - On

3. Starting selector - On position
*The relighting sequence will therefore be automatically carried out as soon as NG less than 17%*

After relighting:

4. [Fuel Pump] or (Fuel P) - Off

*At least 1000’ is necessary to complete relighting procedure after flameout.*


Autorotation (hover IGE)

1. Collective - maintain

2. Pedals - Control yaw

3. Collective increase as needed to cushion touchdown


Autorotation (hover OGE)

1. Collective pitch - fully down

*When NR stops decreasing*

2. Cyclic - forward to gain airspeed according to available height.

3. 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)

1. Twist grip - Idle detent
2. Collective - increase to cushion touch-down


Tail rotor control failure

Land as soon as practicable

If DC parameters correct and no smoke detected:
6. (Master Avionic) or (Avionic) - On
7. All consumers - On, one by one to identify the failed system then keep Off.

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)

1. Corresponding systems - Off
2. Ventilate the cabin

Continue flight depending on failed system

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.

Loss of Ng, tq, or t4 parameters

When a parameter is offline, the parameter value is not displayed on the VEMD upper screen and the parameter scale symbology is displayed in yellow.
The first limits indicator (FLI) is replaced by the 3 data symbology (NG, delta (🔺) NG, T4, and Tq) and a failure message is displayed.


NG, Delta (🔺) NG indicator failure

Respect the maximum Tq value and T4 below 810C

T4 limitations displayed are starting limitations


Torquemeter failure

Respect the NG given in the following table.


Delta (🔺) NG and torquemeter indicator failure

Red GOV warning can also cause loss of Delta (🔺) NG and TQ indications.
The VEMD switches to 3 data symbology with only T4 and numeric NG as valid parameter. Comply with NG limitations in the above table, substituting the Delta (🔺) NG = -4 by a T4 limit of 810C

Bleed valve failure

The bleed valve open flag above the FLI (Green cross hash marks) disappears when bleed valve closes
The bleed valve is normally open when the engine is shutdown during starting and low power settings

- If the flag is not displayed when the engine is shutdown, Check GOV SIGNAL fuse or breaker 30a panel. Do not start engine

- if flag does not disappear at high power setting (near MCP or above), the maximum engine power is reduced, specifically in cold weather.

- if the flag does not reappear at low power settings, the engine may surge. Avoid abrupt changes in power settings.

- bleed valve failure results in GOV illumination
