The Cessna 310 is an American four-to-six-seat, low-wing, twin-engine monoplane produced by Cessna between 1954 and 1980. It was the first twin-engine aircraft that Cessna put into production after World War II.


This aircraft is under active development by The(FGFS)Eagle, ysop(flying) and chad3006.

3D model

Exterior and interior are modelled with a few details and fully animated, we also have most instruments (only navigational ones are missing). The map light is modelled and fully functional. No livery support yet.


Custom vacuum, oil, fuel and procedural electrical system are implemented, along with flaps, gear and engine starting all depending on electrical current being available. Oil system and reservoir leaks are implemented, which can actually set the engine on fire !


At the moment, the 310A variant is being developed, and an FDM for the 310P is available (using the 310A 3D model and systems, however) - further variants are planned.



The cabin entry door can currently only be unlocked from the interior, by rotating the handle down. Then scroll it to open or close the door. Rotate the handle to the horizontal position to lock the door.

Note  If the handle is in the locked (horizontal) position, the door cannot be closed (if it is more than an inch open) or opened (if it is less than an inch open)

The baggage door does not have its handle modelled yet - just scroll the door to open or close it.


In the left front side window there is an openable hatch incorporated, that opens to the outside. To operate it, scroll the handle - it will first rotate to unlock the window then the window will open - scroll the handle into the other direction to reverse the process.


Interactive chocks are implemented - they are by default stored in the baggage compartment. To put them at the current position of the wheels (if the aircraft is rolling fast enough, it will just drive over them), open the baggage door then click them one by one. When the chocks are on the ground, and you should manage to drive over them and fly away - be warned, if you want to have them back you have to collect them where you left them ! Collecting the chocks is done by clicking them again, one by one - this however only works when the baggage door is open.

Oil system

The custom oil system is very realistic (in my opinion), including oil consumption by the engine, increased engine friction when the oil level is too low and leakability of both reservoir and system - but there is a difference between the two leaks: If the reservoir has a leak, you won't see any effect of it until it the level is so low that the oil pump cannot suck from it anymore - only then the system will empty out as well, the oil pressure will drop, and the engine will not be lubricated anymore. If the system has a leak however, the effects can be seen immediately, as oil pressure will go down immediately. Both leak types can be triggered and repaired manually for both engines independently from the Failures dialog (Menu -> Cessna 310 -> Failures).

Warning  There is no way to refill the oil reservoirs (yet) !

Fuel system

On the 310A, there are two tip tanks (50 gallons each) and two optional auxiliary tanks, installed just outboard the engines in the wing. From the fuel selectors in the cockpit, each engine can be set to feed from:

  • no tank (cutoff)
  • the main (tip) tank on the same wing as the engine
  • the auxiliary tank on the same wing as the engine
  • the main (tip) tank on the other wing (crossfeed)

Main (tip) tanks

For the tip tanks, the fuel filler cap is modelled with all details - you have to first unlock it by loosening the two fasteners, then scroll the cap to gain access to the filler.

Auxiliary tanks (optional)

They need to be enabled in the Equipment dialog (Menu -> Cessna 310 -> Equipment), the fuel selector will be changed accordingly, and their fuel level can then be set from the Fuel and payload dialog. Their fillers and filler caps are not yet modelled.

Vacuum system

Each engine drives a vacuum pump, their suction is combined to drive the directional and horizon gyro. A suction gauge source selector is provided on the upper-right of the left switches panel, to enable the pilot to check the suction at four different places:

  • the left pump (LEFT SOURCE)
  • the right pump (RIGHT SOURCE)
  • the horizon gyro (HOR GYRO)
  • and the directional gyro (DIR GYRO)

The suction at the selected source will be indicated on the suction gauge.


The engine controls (throttle, prop pitch and mixture) are located on the top of the center pedestal. On the left and right sides of the pedestal are interconnected knobs to adjust the friction lock of the engine controls.

On the front face of the pedestal are knobs to switch carb heat on and off. They have a locking mechanism to prevent them from creeping to a different position (just like the friction lock on the main engine controls) that can be actuated by scrolling while holding the Shift key. The carb heat is toggled by just clicking, without Shift.

In the case of too low oil pressure, the engines will not be lubricated enough - friction will increase, the temperature will climb, eventually leading to an engine fire if you don't feather the prop and stop the engine.


The flaps on the 310A are a little special - instead of having preset positions you can select with a handle, you have an up / down switch you got to hold into the desired direction until the flaps are at the desired position (displayed on the flap position gauge). That switch is not yet modelled but its behaviour is reflected in the custom key bindings for the [/] keys - hold [ to retract the flaps, ] to extend, both at a rate of 5° per second.
