Can't Start Some Planes

Featured Replies

For some reason I can't start the C172 and C152.  When I use the mouse to turn the switch, the key won't move more than one position and then springs back.  The  only way I can turn the key to the start position is to use the start switch on my Honeycomb yoke.  Then the engine will crank but then die.  Got gas and mixture is in.  So far all the other planes seem to start ok with the Honeycomb switch but the mouse controlled switch acts the same on all planes.  Can't figure wnat's going on here.

it is not 100% clear form your description what is happening.

- if the in game switch is set to something different to the honeycomb position the game should switch back to the honeycomb setting the next time it tries to sync up, with my saitek switch panel that happens as soon as you change any switch on the panel

- which aircraft will not start ? some of the mods need engine.cfg settings tweaked to work with external controllers but generally default planes are fine

EDIT: one more thing, if you spawned cold and dark at parking you may need to turn the fuel on

Assuming you have completed the pre-start checklist, play around with your mouse buttons and wheel and learn how to hold the key in the start position for several seconds without letting it return....

My 1969 MGB roadster sports car is the same way...

This is really getting bizarre.  If I start the C172 using the Ctrl E command the engine will start but after it starts, the ignition key moves by itself back and forth with the engine also shutting off then restarting following what the key does.  Then the engine eventually dies and when I use the Ctrl E command again in an attempt to restart, the key goes back and forth but won't turn enough to start the engine.  After I have let off of the Ctrl E command keys, the key will keep moving back and forth by itself.

When I try to start using the mouse, I hover the curved arrow over the ignition key but can't get the key to turn.  The key will move a little but not enough to move to the next position I've tried using the mouse LH button and also the mouse wheel.  Guess I'll check more planes.  All worked ok until just before the latest hot fix.  Been simming many years so I'm not a noobie, but have never seen anything like this.

Well, I have discovered the source of the problem.  It's got something to do with my Honeycomb yoke.  If I unplug the yoke, all works ok.  Plug it back in and the problem re-occurs.  Any suggestions as to what I should check?

i have no solution, but try a search on the forums with honeycomb?

Are you running any drivers or software for the honeycomb yoke switchgear ?

Sometimes I get the same kind of problem. Cure is Developers Mode, change aircraft, then change back to original aircraft and the problem is solved. Not sure what is being changed by doing that.

Developers mode probably resyncs the aircraft ? no idea.

You could go through the bindings for the yoke in MSFS and see if it's bound to anything related to the starter or magnetos (on the same switch in the cockpit) and just un-bind those items.

The honeycomb yoke has "always on" toggle switches and fs2020 does not properly handle this.   This means if you have the magneto/start switch still bound (it is in the default setup) it would override any attempts to move the starter switch in the virtual cockpit with the mouse.

The toggle and starter switch on the Honeycomb yoke have other unexpected buggy effects like limiting you to 10 degree heading bug changes.   I just unbound all the toggle and start switches on the yoke and just use the virtual cockpit for those functions.  Others have setup FSUIPC to be an intermediary and that seems to work for them.

I did not attempt to compile a list but I have read that MSFS exhibits the same 10° NAV and HDG bug characteristics with some other flight controls, so it is not unique to just Honeycomb.  A method to tune in 1° increments is to use mouse clicks instead of the mouse wheel.

I found my problem, but not how to fix it.

Sometimes when I set up a flight there is 0 gas in any tank!

Other times with the same plane in a new flight, there is plenty of gas. This is why changing planes and back with developer mode would fix  it, it would reset the tanks to 50% gas. I have no idea why sometimes when I create a new flight there will be no gas in any of the tanks. At least I know how to fix that (RESET the fuel level with overhead menu).

You can check/set the fuel and load in the plane selection menu before the flight.

Are your planes being set to zero fuel in the selection menu or are you finding it changes after you hit fly ?

Edited by Glenn Fitzpatrick

No it doesn't change after I hit FLY.

If I load a flight from a .PLN file usually the tank is half full, sometimes loading the same flight from the same .PLN file there is 0 gallons.
