Visual Descent Point Calculator is a planned calculator in the transport section of Super Calculator, covering navigation.
What this calculator will compute
Inputs: MDA, touchdown zone elevation and glidepath angle.
Formula, recorded as scope and not yet verified against a primary source: VDP distance = height above touchdown divided by 300 for a three degree path.
Safety note: descending below MDA without a VDP reference causes controlled flight into terrain.
