Well, I suppose about this trouble. It's result of bad help...
Real AN-2 equipped inertial starter. It allow to start engine even main
battery full discharged - there is handle for spinup wlywheel of starter
manually, from cargo cabin. Usually, for start engine, flywheel of starter
spinned of electric engine.
Main procedure of use inertial starter this:
1. Turn on electrical circuit for supply electrical engine of starter: main
battery switch & starter switch. Red "generator failure" lamp will on, like a
car;
2. Spinup of wlywheel of starter; for this, turn starter selector to left
position and hold it _until wlywheel will spinned_. While wheel spinning,
consumable current will decreasing from max value (see VA-3 instrument) to
value around zero, when wlywheel will spin enough. It take around 7 sec; you
will hear sound of spinned wlywheel.
3. Apply spinned flywheel to engine crankshaft: set starter selector to right
position and hold it _until engine started_. It take several second; see on
tachometer instrument TE-48. When engine achieved above 550 rpm, release
selector and turn off starter switch.
There is one problem around it. Power of starter not enough for spin engine
shaft with big propeller - as I understand, this is JSBsim limitation. I read
about it in devel list, but fix not ready yet. Cause this limitation,
inertial starter may work unstable.
You may discard inertial started at all - go to an2-set.xml and comment
binding of key 32:

It allow you crank engine by press spacebar, as default.
