Introduction m2 AAD
m2 multi AAD
The m2 multi is an electronic automatic activation device, operating on the principle of pressure reading. The primary means for detecting the altitudeand fall rate is a pressure sensor. The altitude is calculated based on the difference between two atmospheric pressures. The pressure at current altitude andpressure on landing location “GROUND ZERO”. The pressure on the landing location is measured and set after switching on the device during calibration.This pressure is automatically adjusted by a change in barometric pressure during the day without the need for user intervention.
The m2 multi checks the ambient barometric pressure every 32 seconds and it determines whether the aircraft has taken off. If yes, it begins to monitor the skydiver’s altitude and fall rate. The pressure sensor measures the atmospheric pressure 8x per second in free fall.
The information collected is evaluated by means of a microprocessor and ingenious software and it is converted to real fall rate and altitude. Thanks to this,the m2 multi device is capable of meeting the preset criteria of fall rate in combination with altitude above the landing location, cut the reserve parachuteclosing loop by means of the cutter and thus initiate the deployment sequence.
The device is activated only in the case the preset criteria are met; the criteria differ depending on the set profiles – STUDENT (Stu), INTERMEDIATE (Int), PROFESSIONAL (Pro), CANOPY PILOTING (Cpi) and TANDEM (Tan)
