Where the numbers come from
Every aircraft in TLAR is checked against a published source: a POH, the manufacturer's data, or our own flight tests. Here is the source for each one, with the engine and propeller we modeled and anything we think you should know.
No aircraft match that search.
A relentless pursuit of accuracy
Certificated aircraft are required to publish performance information in their Pilot Operating Handbooks. Experimental aircraft manufacturers are not, but where they do provide numbers, we compare those too.
We don't compare every published number. We sample low, mid and high pressure altitudes at cold, medium and hot temperatures, and add light and heavy weights where the manufacturer publishes both. Speeds are calibrated: where a POH gives indicated stall speeds and a calibration chart, we correct them. Where a POH has forward and aft CG stall speeds, TLAR uses the mid-CG average.
Landing distance over a 50-foot obstacle is not part of the comparison, because assumptions about pilot technique (glidepath angle, flare distance and delay before braking) greatly affect it. Use TLAR's Fence Height, Fence Margin, TDZ Length and FPA settings to shape the landing distance to your preference, or to closely match your POH. Takeoff over a 50-foot obstacle is affected too, to a lesser extent, so it tends to match the POH less closely than other metrics.
