摘要
A method of establishing a runway approach procedure for an aircraft at a selected runway, comprises, for obstacles in the final approach segment of the flightpath and having obstacle range values greater than the datum range, calculating a missed approach surface height at a projected intersection of a missed approach surface with a descending vertical error budget surface and a corresponding Distance to Height of Missed Approach Surface from the runway (DHMAS). For obstacles in the final approach segment and having obstacle range values less than the datum range, a missed approach surface height and a corresponding DHMAS are calculated using ascending climb gradient requirements. All DHMAS values are compared, and a controlling obstacle is determined as the obstacle having a greatest DHMAS. A decision altitude for the controlling obstacle is calculated, and the runway approach procedure is updated with the decision altitude. Relativistic metadata other obstacles can also be calculated and stored.
