Design Airspeeds and Flight Envelope Calculator (demo)

The Design Air Speeds & Flight Envelope Calculator is a compact engineering windows application for professional and fast evaluation of design air speeds & flight envelope for light airplanes for structural analysis and ground testing. It will help anyone who wants to estimate the V-n diagram for a given airplane configuration.
Printing a flight envelope diagram (V-n diagram)

Complying with the certificate standards and specification requirements in LTF-UL, ASTM F 2245 for LSA / CS-LSA and CS-VLA, this tool is specially prepared for type certification purposes of ultralight aircraft, light sport airplanes or very light aeroplanes.

Engine Mount Design Loads Calculator (demo)

The Engine Mount Design Loads Calculator is a compact engineering windows application for professional and fast evaluation of engine mount design loads for light airplanes with piston engines, tractor configuration for structural analysis and ground testing. It will help anyone who wants to calculate the limit loads (forces and torque) at power plant center of gravity for both main conditions: at take-off and at maximum continuous power.

Complying with the certificate standards and specification requirements in CS-VLA (Very Light Aeroplane), ASTM F 2245 for LSA / CS-LSA (Light Sport Airplane) and LTF-UL (Ultra Light), this tool is specially prepared for type certification purposes of ultralight aircraft, light sport airplanes or very light aeroplanes.

Standard Atmosphere Calculator

The 1976 International Standard Atmosphere model describes a hypothetical, average, vertical distribution (up to 86km / 282.000ft) of atmospheric properties such as temperature, pressure, density and viscosity.
