21 Baro trace check (calibration)
Each flight recorder should be periodically checked to verify that the built-in pressure sensor is still in limits.
The procedure is extremely simple and takes only minutes to finish. The most important action is setting the
Rec. interval in Logger Setup to 1 second otherwise the trace will not be uniform. The procedure is as
follows:
-Turn the unit on and put it into the pressure chamber.
-Set QNH 1013mBar conditions in the chamber.
-Apply a pressure jump to start recording.
-Climb apr. 4m/s and make a stop for apr. 30 seconds every 1000 m.
-After reaching 8000m sink apr. 4 m/s and make stops after every 1000m.
-After reaching zero open the chamber and wait for 1 min then manually end flight.
-Download the “flight” from the logbook.
-Return Rec. Interval setting to previous value.
-Print baro trace using your preferred PC program, for instance Lxe (available on www.lxnavigation.com).
