SimVimCockpit - Engine functions

This page describes the engine related functions added in plugin version 0.9.59.



Emergency MANUAL OVERRIDE lever (MOR) - Eng_Man_Override

If the throttle has failed/stuck, using this lever overrides the throttle.

When you move this lever from AFT (OFF) position forward (by about 4-5%), the engine starts responding and PCL is disabled.



Fuel Level Gauges

Fuel_Level_L, Fuel_Level_R

Fuel Level Indicated (Main/Total or AUX/Nacelle) - depending on aircraft fuel system type this gauge shows:

  1. Total quantity (rep side) or Nacelle when "Fuel_Indicate" switch is ON.
  2. Main tanks quantity or Auxiliary when "Fuel_Gauge_Aux" momentary switch is pressed.

Fuel Totalizer

These parameters will be used for future Fuel Managment control/instruments:

  • Fuel_Used_Reset - reset current fuel used, start counting from this moment.
  • Fuel_Used_ON - Mode: show fuel used since the last reset.
  • Fuel_Rem_ON - Mode: show fuel remaining.
  • Fuel_Rate_Mode - Mode: show reset total, show FF total, show used total last, show remaining.
  • Fuel_Used - Display: shows fuel used since the last reset.
  • Fuel_Total - Display: shows initial Fuel Total.
  • Fuel_Rate - Display: Multifunctional - FF/Rem/Used/etc., depends on the instrument type.


START / IGNITION

An engine "Master_Start" or "RUN" toggle switch (used in Airbus, Challenger CL300, etc.) or handle as in B737. This is the main Master/Run switch or lever - it activates the ignition system (EEC). Opens fuel shut-off (firewall) valves.

  • activates the engine elec fuel pump and mixture control
  • activates EEC ignition control (for future devlopment)

Ignition_Mode

The switch for single-engine plane or single switch for all engines.

1. If assigned as 3-position toggle switch (OFF-AUTO-CONT):

-> From OFF to AUTO - turns only the AUTO ignition ON
-> From AUTO to CONT - turns the CONT ignition ON and AUTO ignition OFF
<- From CONT to AUTO - turns the CONT ignition OFF and AUTO ignition ON
<- From AUTO to OFF - turns the AUTO ignition OFF and CONT ignition OFF

2. if assigned as toggle switch it simply turns the ingniters ON (continuous ignition) or OFF.

The same function is used for separate ignition mode switches for each engine:

Ignition_Eng1
Ignition_Eng2


Igniter_Select

This function is added as EEC selector of the igniter plug (plug 1, 2 or BOTH) or select it as AUTO (norm) for EEC logic, or turn it off.

Can be used for future development (to replicate the EEC logic) or by plane developers if they have a real EEC control, spark plug wear simulation, etc.
When you assign any switch configuration from the layout map, it also sets the ignition selector type variable for the plugin.


Engine_To_Start

This 3-position switch (1-OFF-2) arms either left or right engine to be started when you press the START button.

The same funtion is also used for separate "engine select" buttons (Eng1_To_Start, Eng2_To_Start ...)
By pressing button #1 you arm the engine #1 to start, etc.


Engine_Start

This is the engine start button. It should be assigned as toggle switch, but used as momentary button or spring-loaded switch.

Function: starts the engine that has been selected (armed) with the "Engine to start" function described above.

Another use of the "Engine_Start" function:

When it is assigned as 3-position switch (Start #1- OFF - Start #2) and if the plugin detects that there is no "Engine_To_Start" function assigned, this switch is used to start either the left or right engine, for use in the appropriate aircraft panel.


Start_Mode_Sel (single rotary switch)

or Start_Mode_1, Start_Mode_2... (separate rotary switch for each engine)

This function is modelling engine Ignition/Start mode switches for different aircraft models.

When you assign any switch configuration from the layout map, it also set the start/ignition type variable for the plugin.
So, the plugin is processing the switch logic according to the selected plane ignition system.


Starter Return/Release

The "Starter_Return" parameter is useful for panels that have the starter switch held in the "start" position until the engine is launched and reaches a set RPM. The parameter can be assigned to an actuator that should return the starter switch into off position when the engine has started. You can read more about making such a mechanism here.
