This is important with warm weather, at higher altitudes, with heavy loaded aircraft and with helicopters. | This is important with warm weather, at higher altitudes, with heavy loaded aircraft and with helicopters. In FlightGear the density of the air is simulated making a helicopter stick to the ground on a warm day on a high elevation helipad or making it impossible for the heavy loaded Antonov depart from Mexico City. The [http://en.wikipedia.org/wiki/Density_altitude density altitude] is calculated from the barometric pressure and the temperature. The higher the temperature, the lower the density, the higher the density altitude (in reference with the [[#True altitude]]). | ||
