  3. Indicating and Control Panels VEMD Description (Vehicle and Engine Multifunction Display) Module No. 2 Module No. 1 Upper Screen Lower Screen Control Buttons 11.3

  4. Engine Page • P2 Bleed Air Indication (with sand filter) • T4 in Degrees C • Torque in Percent • NG and NG in Percent • Fuel in Percent • Fuel Quantity in Pounds, Gallons, • Kilos, or Liters • Outside Air Temperature • Vehicle Page • Engine Oil Temperature and Pressure • Voltage and Current of the Electrical • Power Source (Battery, APU, or Generator) • Fuel Flow in Pounds, Gallons, Kilos, or • Liters / Hour • Messages • Fuel Endurance Remaining 11.4

  5. VEMD In “Start-Up” Mode T4, NG, and Torque: digital value and analog scale The VEMD switches automatically to the First Limitation Indicator at ~ 60% NG. Bleed Valve Flag Fuel Quantity: digital value and analog scale Outside Air Temperature Error Message Area Engine Oil Pressure and Temperature: digital value and analog scale START Digital value of volts on electrical busbar Digital value of starting current - 200 Error Message Area 11.5

  6. VEMD In “Flight” Operational Mode FLI analog scale, plus digital values of NG, T4, & Torque parameters. 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. “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. 11.6

  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. 11.7

  8. 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. Performance Not yet available. 2866 lb lb 0160 0441 1212 lb 470 lb 480 +16 IGE 4960 lb lb 5000 OGE 6173 lb 11.8

  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. 11.10

  11. 5 T4 820 0C 7 3 9 x100 -4 -8 -12 TQ 4 FLI FAILED Parameter Monitoring The NG parameter is invalid. The FLI symbology is replaced by the 3-scale display, however the NG value is not shown. Error Message Different values have been detected between processors 1 and 2. The display is inhibited. LANE 1 PARAM FAILED Error Message 11.11

  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. 11.12

  13. 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.) Flight Manual - Emergency Procedures - Page 3 - 7 11.13

  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.

  15. Caution Messages on VEMD • 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. 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 from the pilot. • LANE 1 (or LANE 2) FAILED • PRESS OFF 1 (or OFF 2) : Self-explanatory Flight Manual - Emergency Procedures - Page 3 - 7 11.15
