 In the Aerofly FS 2 an ''airbrake'' represents a controllable area that creates drag.

 ===== Function Description =====
 The airbrake is probably using something similar to this formula:
-<code>F_d = 0.5 * rho + v^2 * Cd * Area * Control</code>
+<code>F_d = 0.5 * rho * v^2 * Cd * Area * Control</code>
 Where

   * ''Control'' is the dynamic input values between ''0.0'' and ''1.0'' that scales the Area linearly
   * ''X0'' is the direction of the airbrake where it is acting (usually this is the x-axis but it could also be pointing upwards.
+  * rho is the air density at the Body.R position in the world (+R0 properly rotated with the Body orientation as far as the author of this text wants to believe)
+Then the calculated drag is acted upon the ''Body'' at the ''R0'' location along the ''X0'' axis. The real formula used may be a lot more complex to account for the rotation speed of the ''Body''.
