Know your numbers before you line up.

MTOW Perf turns the POH tables of your aircraft into weight & balance, takeoff and landing data – with the source of every value and the sheets filled in.

No card needed. Built from the POH, not from rules of thumb.

What it calculates

Everything a pilot checks before a flight in a light aircraft – in one pass, in the same order every time.

Weight & balance
Every station of your aircraft, ramp to landing mass, with moments and the CG checked against the envelope at zero fuel, takeoff and landing.
Takeoff performance
Ground roll and distance over 50 ft from the POH tables – pressure and density altitude, OAT, wind, runway surface and slope, air conditioner.
Landing, return and go-around
Landing distance at the destination, an immediate return to the departure airport, and a takeoff again after a go-around.
Weather and runways
METAR and TAF from three sources, wind components on the true runway heading, runway lengths with displaced thresholds.
Your aircraft
Each registration with its own weighing data. Built-in, checked types – or enter the POH data of any other type once.
Saved flights
Keep a flight setup for 7 days and use it again for the next similar flight – with fresh weather, of course.
Load sheet and T/O data sheet
Filled-in PDF sheets, ready to print or to take on the tablet.
Every value has a source
Each step shows the POH page, the formula and the result. Out of the tables? The calculation stops instead of guessing.

It stops instead of guessing.

No extrapolation. Outside the POH tables – too hot, too high, too heavy, too much tailwind – the calculation is blocked and tells you why.

Conservative rounding. Distances round up, headwind rounds down, gusts count for tailwind and crosswind.

Nothing filled in silently. Missing temperature or QNH stays missing until you enter it from a valid source.

How it works

  1. 1

    Select aircraft

    Choose the registration – mass, balance and limits come with it.

  2. 2

    Enter the flight

    Route, time, occupants, baggage and fuel. Weather and runways load by themselves.

  3. 3

    Calculate

    Weight & balance, takeoff, landing and fuel, checked against every limit.

  4. 4

    Take the results

    Clear verdict, full audit trail, and the sheets as PDF.
