Any good FMC addons, that are free?

The Honeywell one I have installed sucks. It sets speeds at 458 IAS for my cruising altitude, that's WAY to fast, causing overspeed. The Honeywell seems to not understand IAS and TAS at high alititudes.

Freeware ones?  Probably not!  Payware if you want one that works!

Just going to run a Chromebook and not upgrade to a Windows computer. Too many problems with the new Sims! 😱
Trying to keep peace and harmony and the will of Landru on the site seems to be a full time job!

I would just use a payware aircraft.... FAR BETTER and you'll never have the integration with a freeware CDU/FMC than you do with a payware model.

 

Best wishes.

The freeware honeywell erroneously reads the cruise speed instead of the maximum indicated airspeed. You can simply lower the number in the aircraft.cfg and the fmc will now read the correct value.

If you look at the airspeed indicator, you will see that the maximum speed is always lower than cruise speed.

I don't use that Honeywell gauge anymore but when I did I changed the line in fmc.xml that looked like this:

(A:DESIGN SPEED VC,knots) (>L:fmcBendixGA_CruzAirspeed)

to this:

(A:AIRSPEED BARBER POLE,knots) 20 - (>L:fmcBendixGA_CruzAirspeed)

If the smaller Airbuses are your thing, these are free and come with a working FMC:

Regarding the Honeywell FMC and to follow Barry's approach for fixing the cruise speed, this code will convert the fixed cruise TAS from the aircraft.cfg to IAS based on flightplan altitude:

(A:DESIGN SPEED VC, knots) (C:fs9gps:FlightPlanCruisingAltitude, feet) 1000 / 0.018 * 1 + / (>L:fmcBendixGA_CruzAirspeed)
