FlyingIron Simulations Spitfire Update

FlyingIron has issued yet another update for their Spitfire for MSFS. Update 1.2.1 fixes a few issues that were inadvertently introduced with the previous major update (1.2.0). One of the most notable fixes has to do with the fuel functionality, with changes to the fuel pump, wobble pump and fuel valve logic. There were also fixes made to the flight model to account for updates in Sim Update 9, as well as changes to the sound among other things. Last but not least, the update post by FlyingIron contains a small teaser for one of their upcoming planes, with what appears to be a Focke-Wulf Fw 190 obfuscated in the background.



  • Reverted fuel pump to OFF during cold start
  • Set default pilot to WWII
  • Improved fuel valve logic. The fuel valve can now be toggled with the Toggle Engine 1 Fuel Valve keybind.
  • GNS430 can now be powered on/off with the COM1 volume button
  • Improved the rudder trim wheel interaction speed
  • Fixed radiator flap not responding to manual override
  • Fixed clock animation
  • Halved the speed of icing
  • Improved the baro knob
  • Wobble pump logic improved
  • Added aileron trim control to tablets settings. Be sure to TURN OFF ‘Auto Rudder’ in the assistance settings as this is causing major right roll.
  • Base oil temperature slightly decreased
  • Optimized primer animation and interaction code
  • Canopy slide auto-shuts under a steeper angle now, making it easier to open on approach.
  • Transponder digit rolls corrected
  • Fixed checklists by removing incorrect idle/cutoff reference
  • Fixed CTD when saving custom camera views
