7 IGC Flight Recorder
PowerFLARM Fusion operates as an IGC-approved flight recorder (level 3, badges
up to diamonds). It also has Engine Noise Level recording (ENL).
Note: The pressure sensor is precalibrated when shipped. If calibration is
required for FAI/IGC purposes (e.g. record flights), this should be done by
an appropriate entity.
PowerFLARM Fusion has an internal memory for approximately 50 hours of flight
recording at a 4 s interval. Flight recording automatically starts when the aircraft
starts moving and ends when Fusion is switched OFF or after more than 10 minutes
on the ground. When the memory is full, the oldest flights are overwritten first.
To read out the flights, use FLARM Hub (see Section 3.6). It is also possible to read
out all IGC files to a USB flash drive:
1. Switch PowerFLARM Fusion OFF after flight (allow at least 2 minutes after
landing to avoid losing data)
2. Connect a USB flash drive (see Section 4 for usage of USB flash drives)
3. Switch Fusion ON
4. Observe Status LED or progress indication on display to verify that flights
are being copied
5. Wait until the system has started up normally after copying the flights
6. Disconnect the USB flash drive
Some displays and flight computers allow reading out flights without switching
Fusion OFF after the flight. Refer to the display documentation for details.
