Mission Performance

Stall, approach, cruise, range, ceiling and climb — the higher on the chart, the better, on every axis.

Each axis is scaled independently across the compared aircraft and printed in its own units; every vertex sits at the published figure. Higher is better on all axes: Stall, Approach and Fuel Burn are inverted (lower = higher). A missing figure breaks the line at that axis.

Capability & limits

Each bar stacks your selected occupants against full fuel and the aircraft's useful-load limit (the black line). The open gap between them is spare payload. Add an occupant and the gap closes; once it's gone, fuel has to give.
