The AMS (Aircraft Monitoring System) comprises a thrust and torque sensor (TNT-Meter) connected to onboard electronics, enabling real-time recording of flight and engine parameters. Designed to quantify aerodynamic and propulsion effi-ciency, the AMS aims to optimize overall aircraft performance, increasing pay-load capacity, range, and endurance. Compatible with all types of electrically powered aircraft, including UAVs, VTOLs, and airplanes, the AMS provides versa-tile monitoring capabilities for enhanced operational efficiency.
TNT-Meter Capacity
Our current range of TNT sensors have the following load capacities. Different load capacities can be studied on request.
| Model | Thrust | Torque |
|---|---|---|
| TNT-050-02 | 50 N | 2 Nm |
| TNT-100-05 | 100 N | 5 Nm |
| TNT-250-15 | 250 N | 15 Nm |
| TNT-500-30 | 500 N | 30 Nm |
| TNT-750-50 | 750 N | 50 Nm |
The AMS can be used on different aircraft sizes. This estimation is based on the ratio Mx. Thrust / Mx. Weight:
- > 0.4 for fixed wing aircraft,
- > 2 for multirotor aircraft

Computed accuracy (fixed wing aircraft)
The computed accuracy is determined analytically from sensors manufacturer datasheets assuming that the wing area, the total wetted area, the flight weight, the wing aspect ratio and the Oswald efficiency factor are known.
