What is the Horn switch used for?

On the console, a HORN switch is used to activate the audio warning.
When HORN switch is set to ON: HORN light goes out

Explain the continuous tones:

Two continuous tones can be heard:
– a 310 Hz tone when Nr is below 360 rpm
– a 285 Hz tone when max. takeoff rating is exceeded
— After 1.5 sec. delay if power remains within transient range
— Immediately when max. transient rating is or will be exceeded during fast power increase

Collective pitch - REDUCE to maintain Nr in normal operating range or power within limits.
Engine parameters - CHECK

Explain the intermittent tone:

An intermittent tone (310 Hz) is heard when the Nr is above 410 rpm
1. Collective pitch - Increase to maintain Nr in normal operating range
2. Apply procedure according to situation

What is the autorotation procedure over land after an engine flame-out?

Collective pitch - REDUCE to maintain Nr in normal operating range
IAS - SET to 65 kts
- If relighting impossible or after loss of tail rotor thrust
Twist grip - IDLE position
Maneuver the aircraft into wind on final approach
- At height + 70 ft
Cyclic stick - FLARE
- At 20/25 and at constant attitude
Collective pitch - GRADUALLY INCREASE to reduce the rate of descent and forward speed
Cyclic - FORWARD to adopt a slightly nose-up landing attitude (<10degrees)
Pedals - ADJUST to cancel any side slip tendency
Collective pitch - INCREASE to cushion touch-down
- After touch-down
Cyclic, collective, pedals - ADJUST to control ground run
- Once the a/c has stopped
Collective pitch - FULL LOW PITCH
Rotor brake - APPLY below 170 rpm

Explain the autorotation procedure over water:

Apply the same procedure as over land, except items 10, 11, and 12, but maneuver to head a/c equally between the wind and wave direction on final approach. Ditch with minimum forward speed (IAS < 30 kts) and rate of descent. Then apply:
10. Collective pitch - MAINTAIN
11. Doors jettison handles - PULL-UP
12. Rotor brake - APPLY
Abandon a/c once rotor has stopped

What is the procedure for engine failure in a hover IGE?

Collective - MAINTAIN
Pedals - CONTROL YAW
Collective - INCREASE as needed to cushion touch-down

What is the procedure for engine failure in a hover OGE?

Collective pitch - FULL LOW PITCH
- When Nr stops decreasing
Cyclic - FORWARD to gain airspeed according to height available
Autorotation procedure - APPLY

What are the symptoms for a complete loss of tail rotor thrust?

The helicopter will yaw to the left with a rotational speed depending on the amount of power and the forward speed set at the time of the failure

What is the procedure for a complete loss of tail rotor thrust in cruise flight?

Approach and landing
- On a suitable area for autorotative landing:
1. Twist grip - IDLE position
2. Carry out an autorotative landing

What are the symptoms of a loss of tail rotor control?

Jamming of pedals or loss of effectiveness of the pedals
These conditions make it impossible to control tail rotor thrust with the pedals

What is the procedure for a loss of tail rotor control?

Cyclic and collective - Adjust to set IAS to 70 kts
Hydraulic cut-off switch (collective) - OFF
[ACCU TST] - Press for 2 sec. (load compensator depressurizes)
On a suitable area for a running landing procedure:
- Make a shallow approach with a slight left sideslip
- Perform a running landing, the sideslip will be reduced progressively as airspeed is reduced and collective is applied to cushion the landing

What is the procedure for failure of 1 VEMD screen?

OFF1 or OFF2 - OFF
- Read all info on the other screen
- Info is available using the SCROLL pushbutton either on the VEMD or on the collective grip
- If the top screen fails, the 3-parameter engine page will be automatically displayed on the lower screen

What is the procedure for failure of both VEMD screens?

To avoid any power overlimit, the max. authorized power will be the power needed to establish level flight with the following law:
IAS kts = 100 kts - 2 kts/1000 ft
LAND AS SOON AS PRACTICABLE
Carry out a no-hover landing

How are caution messages displayed on the VEMD?

- When a parameter is off line, the parameter value is not displayed on the upper VEMD 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 CWP, no other action is required from the pilot - If an overlimit is displayed it is recorded in the VEMD and will be displayed on the engine page until Ng = 40% during the following engine start - If no light is displayed: CONTINUE FLIGHT

What is the procedure for an Nr indication failure?

- Nr indication failure 1. Collective - MAINTAIN Tq > 10% Nr reading is given by Nf pointer LAND AS SOON AS PRACTICABLE

What is the procedure for an Nf indication failure?

- Nf indication failure 1. Nr gauge - CHECK in normal operating range with Tq > 0 CONTINUE FLIGHT NOTE 1: The Nf value can be read on the VEMD screen. Press [SELECT], then [+] as many times as required to dispay the parameter in the rectangular window at the bottom of the FLI or 3-data screen NOTE 2: In case of Nf indication failure, EBCAU may not be available

What is the procedure for Engine Oil Temperature over 115C?

What is the procedure for low engine oil pressure?

What happens when you lose Ng, Torque or T4 parameters?

- When a parameter is off line, the parameter value is not displayed on the VEMD upper screen and the parameter scale symbology is displayed in yellow. - The FLI is replaced by the 3 data symbology (Ng/deltaNg, T4, and Torque) and a failure message is displayed

What is the procedure for an Ng/deltaNg Indicator failure?

Land as soon as practical
