T2000SFL Transponder (Rev8) - WT-0204: Frequently Asked Questions

« Return to Product Information
My QNH/Baro reads in the oppostire direction!

Refer to T2000SFL AB-001 on our home page.

If I adjust the QMH/Baro altitude what does ATC read?

The T2000SFL transponder will only transmit the encoder altitude (pressue altitude) in accordance with Mode C Operation. The adjusted QNH/Baro altitude is never transmitted.

Calibration - is it necessary?

Yes. In most countries, regardless of type of aircraft, if a transponder is installed it must be calibrated at the time of installation and every two years thereafter.
