Here I go again. Can't find the parameter for the CFG file for manual gear extension. One of my new projects is a glider with a single retracting gear. There is no electrical system other than a small battery for the COM, GPS, and a gear light. The battery only seems to last a short time, after which the COM goes black and the gear no longer works. I need to get into the CFG and design an electrical system away from the defaults that reflects these 3 small current draws, and also to get the manual gear set up. Any ideas on the tag/parameter?

Hi Harold,

From what I understand, you want to have a electrical current with it's own bus for the gear?

a quick overview from another aircraft's cfg:

[electrical]
            ;BusType, MaxAmpLoad, MinVoltage    BusTypes:0=MainBus,1=AvionicsBus,2=BatteryBus,3=HotBatteryBus,4-7=Generator/Alte
rnatorBus(1-4)
flap_motor       = 0, 5 , 17.0
gear_motor       = 0, 5 , 17.0
autopilot       = 0, 5 , 17.0
avionics_bus    = 0, 5 , 17.0
avionics          = 1, 5 , 17.0
pitot_heat       = 0, 2 , 17.0
additional_system = 0, 2 , 17.0
marker_beacon    = 1, 2 , 17.0
gear_warning    = 0, 2 , 17.0
fuel_pump       = 0, 5 , 17.0
starter1          = 0, 20, 17.0
light_nav       = 0, 5 , 17.0
light_beacon    = 0, 5 , 17.0
light_landing    = 0, 5 , 17.0
light_taxi       = 0, 5 , 17.0
light_strobe    = 0, 5 , 17.0
light_panel       = 0, 5 , 17.0

Now maybe you can have the gear motor running on a seperate bus and the rest on the avionics bus? I never played around with these, but I also see the default glider does not have any electical system in the cfg at all...?

For FS2004 or FSX.....

For a system that won't discharge - add this line to the [electrical] section

electric_always_available = 1

or you can configure individual equipment by lowering the minimum voltage to less than 7 volts. The sim never discharges to less than 7 volts. Example:

avionics_bus = 0, 10,

6.9

you can increase the life of the battery by reducing the 'max amps load' for the bus or component.

avionics_bus = 0,

0.1

, 17

Gear system type is in the [contact_points] section

gear_system_type=3 //=manual gear operation

0 = electrical
1 = hydraulic
2 = pneumatic
3 = manual
4 = none

MSFS documents describing the aircraft.cfg file parameters-

FS2004- download the Aircraft Container SDK-http://www.scenery.org/tutorials_fs2k4_SDK.htm

FSX-it's in the SDK document 'fsxsdk.chm'-SimObject Container SDK section-or online here-

Harold goes from designing bottle rockets with people strapped to them, to gliders? Huh

Who are you and what have you done with Harold?!

Hi guys, thanks for all the help. Actually I want manual gear. I also need a very low draw on the battery to keep the Com Radio alive, and the GPS, and the gear light. So both posts will help.
As for the rockets… I am the same person. It is not the speed but the cockpit. All three aircraft use the very same cockpit, just with the instrument panel and controls differing for the type of aircraft. Check out my web site at www.dickert.ca/swift to see what I am talking about. This is the same idea as Airbus, and Bombardier for their various Regional Jets. The 200 and 700 are different aircraft but are virtually the same at the front office. All three of my aircraft are very small but the cool thing is I can re-use the VC with minimal new modeling.
