Approach Speed Calculator

Inputs

Landing stall speed (Vso)

kt

Reference factor (k) Common training arithmetic uses 1.3 x Vso, but aircraft-specific procedures control.

Steady wind (W)

kt

Gust speed (G)

kt

Results

Default result

Target approach speed

62.5 kt

Pass

Also computed

Base reference speed 58.5 kt

Gust additive 4.0 kt

Target/stall ratio 1.39

Method notes 2 notes

Uses base speed = factor * Vso and gust additive = half the gust spread.
Aircraft manuals, operator procedures, runway length, conditions, gust limits and stabilized-approach criteria control actual approach speeds.
