The TMC file is an Aerofly FS 2 text file that contains the general description of an aircraft such as the name as shown in the aircraft selection menu, the description text in several languages and some values describing how large, how fast, how heavy the aircraft can be and which aircraft category it belongs to. The actual speed, mass and behavior of the physics are defined in the tmd file.

A different kind of tmc file is the model.tmc, which defines how the 3D model and textures are to be converted, e.g. the texture resolution for each quality setting.

        <[string8][DescriptionTextEN][The medium-range jet airliner Airbus A320 entered service in 1988. It is the first model of the A320 family, whose members differ in fuselage length mainly. The shortest family member is the A318, the longest is the A321. The A320 has a maximum take-off weight of 170000 lb and can carry a maximum of 180 passengers. The A320 was the first commercial airliner that used a digital fly-by-wire control system. The mechanical connection between the flight controls and control surfaces is replaced by a combination of sidesticks, flight control computers and actuators. The cockpit features digital instrument displays for all flight and engine data, analog instruments are provided as a backup only.]>
        <[string8][DescriptionTextDE][Das Mittelstreckenflugzeug Airbus A320 ist seit 1988 im Einsatz. Es ist das Basismodell einer Reihe von Modellen, die sich vor allem durch die Rumpflänge unterscheiden. Kleinstes Modell ist die A318, größtes Modell die A321. Die A320 hat ein Abfluggewicht von bis zu 78000 kg und kann maximal 180 Passagiere befördern. Mit der A320 wurde das Fly-By-Wire System bei zivilen Flugzeugen eingeführt. Der Pilot steuert dabei nicht über ein Ruderhorn mit direkter Verbindung zu den Rudern, sondern indirekt über Aktuatoren die wiederum von einem sogenannten Sidestick gesteuert werden. Auch im Cockpit wurde nahezu komplett auf neue Technik gesetzt.]>

Content Description


Whenever there are significant changes that would render an aircraft incompatible with the latest version of Aerofly the version number is increased. Any aircraft that is not yet updated to be compatible automatically is shown as not compatible with the version and the user cannot select that aircraft from the selection menu. This ensures that, after an update to the Aerofly FS 2 base, any old aircraft is attempted to load.


The DisplayName attribute sets the aircraft name that is shown in the aircraft selection menu. You may include spaces and special characters.


The attributes DescriptionTextDE, DescriptionTextEN, DescriptionTextES, DescriptionTextFR and DescriptionTextJP define the aircraft description text that is show inside the Aerofly aircraft selection menu. They are selected depending on the user's language setting. If a text for a certain language is not defined the aerofly replaces it with the English description text, so if you don't know all languages it's possible to remove these lines.


The ContactSpheres is a list of 3D vectors (x,y,z) and a size (radius) that define the attitude of the aircraft when the simulation places it onto the ground. The lower the z value (3rd value) the higher up the aircraft is placed.

WingSpan and Mass

WingSpan and Mass are used internally to have an idea of the overall dimensions and mass of the aircraft.

Category Flags

Airplane, Helicopter, Glider, Jet, … are all tags that help Aerofly categorize the aircraft.


MinimumSpeed defines the speed at which an aircraft is initialized when quick lift up is activated or when the aircraft is switched in the middle of the flight (it checks weather the speed is between MinimumSpeed and MaximumSpeed)

The other speeds are used for the calculation of the route parameters and for the flight information at the top of the screen.


All parameters starting with a Q should be thought of as values from a quartet game, where is lists all kinds of attributes of an aircraft like year the virgin flight QVirgin, the total number of aircraft built QBuild, glide ratio for gliders QRatio as well as self explanatory values for mass, thrust or power, speed and mass.

Flap Info

For the internal logic, e.g. which flap to select when you change from one aircraft to another mid flight the flap input (ranging from 0 to 1) is mapped to either a flap setting (qualifier discrete) or to a flap angle (qualifier empty).

The FlapSettings is a map of 2d positions with the first value representing the flap input (e.g. 0.0, 0.25, 0.5, 0.75, 1.0) and the second value representing the selected flap position (e.g. 0.0 = up, 1.0 = conf.1, 2.0 = conf.2, 3.0 = conf.3, 4.0 = full or 0.0 = up, 0.08726 = flap 5 degrees, 0.69808 = flap 40 degrees)


Defines which pilot model should be used for the human_graphics animation.
