This calculator helps you correctly set the QFE pressure in hPa while using the Abs-mode (see User Manual for Multi Tactical m2 AAD, Chapters 4.2.4 and 4.3.4).

The whole procedure (which results in a QFE pressure in hPa) is calculated in the ISA (International Standard Atmosphere).

This is the pressure measured by calibrated pressure sensor (m2 Tactical can be used for this purpose) directly at the required landing area. Entering of this measured ABS pressure into m2 Tactical device means the most accurate function of the device according to the selected profile.

Calculation with calculator is necessary if the ABS pressure from the planned area is not available.

1. Enter the pressure recalculated on sea level according to freely available maps at the planned landing area. Also enter and check the pressure units hPa or inHp used on the selected meteorological map.
2. Enter the altitude of the selected landing area according to freely available maps. Also enter and check this altitude in meters, or feets. The units will be indicated on the selected map.
3. Press the “calculate result” button after entering and checking all data and the pressure will be recalculated to ABS on the selected landing area. Enter this value into m2 Tactical and the device will operate according to the selected profile to the selected landing area.

A slight height differences in the function of m2 Tactical device (tens of meters) can occur when using the recalculation with calculator due to different temperatures. 

The m² multi Tactical device is designed and manufactured on the basis of latest knowledge focusing on military skydiving, tactical use for military purpose, police force tasks or rescue operations and its functions fully comply with the requirements for professional use and training.

The device monitors the fall rate and altitude of the skydiver above the landing location. If the activations parameters are met, the cutter automatically cuts the reserve parachute closing loop and thus initiales the sequence of reserve parachute deployment.
