Is anybody Aware of an iphone application where you can input the known variables such as rwy elevation, platform altitude and or distance to threshold(FAF), DME offset from threshold if applicable. And temperature.
And obtain DME vs altitude table, flight path angle required in percent and degrees.
Basicaly a simple trigonometric function where the variables can be inserted.

If you're in no-charted-profile land, 3 x the DME+the threshold elevation-(the distance from the threshold to the DMEx300ft). ;)
