What fits on 8,099 feet
Each bar is the runway that aircraft needs here — its published sea-level balanced field length, increased for this field's elevation. The vertical mark is the runway that actually exists.
Elevation increases the takeoff run. This chart applies a 9 % increase per 1,000 ft of field elevation to each aircraft's published sea-level balanced field length at maximum takeoff weight — a planning approximation, not the operator's performance data. Real departures are rarely at maximum weight, so an aircraft shown as restricted here will often fly with reduced fuel or payload.
