Air Density Edit

Air density with altitude is simulated. At a higher altitude, air gets thinner. Engines have a harder time producing thrust as they get choked for air, and there is less drag. Overall, this leads to a balance where aircraft are be able to fly faster at a high altitude with the same throttle setting than at sea level. Wings produce less lift in the thinner air, so increasing nose up attitude or speed is needed.

Supersonic Flight Edit

The game has sonic booms and vapor cone effects.

Thrust-to-Weight Ratio (TWR) Edit

The thrust to weight ratio's of all aircraft are critical for understanding their maneuverability. Essentially it is a measurement of the amount of thrust provided by the engines, compared to the amount of combined mass or weight of the aircraft that thrust has to push. This factors in fuel, payload, everything. If your TWR is over 1.0, this means that your aircraft will be able to climb vertically, as the thrust is greater than the mass. A TWR of 1.0 means that your engines can hold (without wing lift or anything else) 1 of your aircraft in the air vertically, however this means that you will not accelerate vertically (without VTOL you will stall at this point).

A TWR of 1.5 means that your engines can push 1.5 times your current combined aircraft mass. The .5 difference is what will make you accelerate straight up. An aircraft with less than 1.0 will need wing lift to maintain altitude and cannot go vertical. When operating VTOL aircraft like the AV-42 Kestrel, the TWR must be greater than 1.0 for vertical take-off and landing. If it is not, the Kestrel has to be used in a traditional aircraft mode and use lift from air under the wings to take off and land. TWR is constantly changing as fuel depletes and weapons are fired. Jettison any un-necessary equipment, fuel tanks, or weapon racks to increase TWR and therefore increase maneuverability. TWR also plays into horizontal acceleration and turn radius. High TWR's are essential for air-to-air combat and evasion of missiles. In real life there can be different TWR scenarios for each aircraft, one for "dry power" (no afterburner) and one for with afterburner. But for the purposes of VTOL VR, TWR always assumes engine throttle is at 100% with afterburners.

Other Unsimulated Effects Edit

  • Ground effect
  • Turbulence
