Single Engine GA
Regulations define a minimum gradient of 2.1 % for Instrument approach procedures respectively 2.5 % for low visibility approaches. Sometimes higher gradients are defined according to the obstacle situation. Lets assume an approach where the minimum gradient is 4 %. The Airbus LPCNG is showing a 4% gradient. So far so good. Now in you have to perform a go around below the minimum one eng out you wont be safe anymore.
Safer would be to fly the one eng out procedure. But how do I know that this will bei safe as well and how much is the gradient it is based on. The lpcng landing module of Airbus doesnt calculate for the obstacles. It calculates with a gradient of 2.1 %. But if the eng out procedure is obstacle limited the resulting max landing weight would be wrong.
Any recommendations on that ?
