The Mikoyan and Gurevich MiG-21bis is a supersonic jet fighter aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union.
FlightGear Versions
There are currently 2 versions of the MiG-21bis available in FlightGear:
- An older version in FGAddon
- An actively developed version in a Git repository
Eventually, the version in FGAddon will be updated at intervals with the version on Git. The instructions below are covering the Git version, as it is more complete and realistic both in terms of flight model, systems and for supporting military simulation.

Aircraft Help
Checklists
There are ca. 10 Aircraft_Checklists, which can help in many situations.
Engine and Throttle Management
In general the engine of the Mig21-bis is less responsive than that of a modern jet fighter - and throttle and engine management is more subtle.
N1 and N2 are the rotational speeds of the engine sections expressed in percentage instead of in the actual rate of rotation. If N1 gets too much higher than N2, you will cause an engine surge (can happen at as low as 20% separation, it's guaranteed by 30%). Therefore one needs to keep an eye on the N1 and N2 needles and sudden changes in the throttle over a large range are bad. The max N1 to N2 ratio depends on airspeed as well, so you'll have to make sure you don't blow up your engine on a dive. The tachometer r.p.m. gauge is situated on the right side of the front panel in the cockpit - below the radar warning receiver and to the left of the radar screen.
On the other hand the air intake cone in the nose is handled by the plane automatically, i.e. without necessary pilot intervention.
Second reheat (CTRL-f) is only effective below 15,000 feet mean sea level, and use should be limited to 3 minutes.
Weapons Management
There is a separate wiki article for MiG-21_Weapons_Management.
There is an external article about navigation, which eventually will be migrated to this wiki.
