6. VEMD In “Flight” Operational Mode
The upper screen shows all the engine limitation data on the First Limitation Indicator.
During start-up, the FLI is automatically displayed
at ~ 60% NG.
FLI analog scale, plus digital values of NG, T4,
& Torque parameters.
“SCROLL” pushbutton for selecting display -
FLI or 3-Scale display.
Note: Collective Lever also has a “SCROLL” button.
The three primary engine parameters (NG, T4, & TRQ)
are displayed in an
easy-to-use synthetic form
for monitoring engine power:
0 = zero power
9.6 = Max Continuous Power
9.6 to 10 = Take-Off Power
10 = Max Take-Off Rating
10.4 = Max Transient Power (5 s)
FADEC = Full Authority Digital
Engine Control
Digital value of
generator current.

7. Test Pattern The test pattern helps to check both screens.
A target number is
displayed on the screen.
Pressing the “Light Test”
button activates the screen.
This page is displayed on
both screens.
The alpha-numeric code
shown indicates the
software version installed
in your VEMD.

8. Not yet available. Performance
Pressing “SCROLL” twice displays the “Performance” page; the pilot then uses the “+”, “-” and “ENTER” keys to record the payload carried. The VEMD computes the AUW (All-Up Weight [Gross Weight]), and the maximum takeoff weights in IGE or OGE conditions.

9. In compliance with the Flight Manual, the pilot can check engine power by selecting “Engine Power Check”. The VEMD indicates the conditions that need to be observed to initiate an Engine Power Check. Every condition requires a pilot action. Once every condition has been met, the VEMD proceeds automatically.
Engine Power Check
11.9

10. Engine Power Check
The test runs in three phases denoted by rectangles on the VEMD screen. If the flight parameters are not updated, the test repeats the previous phase. On completion of the test, which lasts about 30 seconds, the results are shown on the screen.

12. Flight Report
At the end of the flight when N1 < 10% and NR < 70 rpm, the VEMD switches automatically to the “SHUTDOWN” mode. The VEMD then displays the Flight Report:
flight number (automatically incremented)
flight time
generator & turbine cycles (computed by the FADEC) [NG < 60% until NG > 50%]
overlimits or failures detected during the flight.

VEMD Screen Failure
- failure of one screen
Select the failed screen to OFF
Read the information on the other
screen.
All the information is available using the SCROLL push-button either on the VEMD or on the collective pitch lever.
If the top screen has failed, with the lower screen in 3-parameter mode ( NG, T4, Torque), only T4 and NG will be available.
(Refer to the procedure provided in the Flight Manual, paragraph 3.5.4, ‘Loss of Ng, Torque, or T4 parameters’ for compliance with limitations.)

14. VEMD Screen Failure - failure of both screens
[ First, insure that the Day / Night switch
is in the appropriate position. ]
[ Real failure is highly improbable ]
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 overlimit, the maximum authorized power will be the power needed to establish level flight with the following law:
IAS kt = 100 kt at sea level minus (2 kt / 1000 ft Hp)
Landing procedure: carry out a no hover landing.
LAND AS SOON AS PRACTICABLE
