Section 7.0 Instructions for Continued Airworthiness

The SSD120-(XX)N-RS5 is an all solid-state device and requires no periodic maintenance to
maintain its airworthiness. The altitude encoder is to be tested during the aircraft biennial
transponder and pitot-static system test as required by Federal Aviation Regulations. If the
altitude encoder reports an error in excess of ±125 feet when compared to the primary flight
altimeter, then recalibration as per §4.0 of this manual is required. If the error cannot be corrected
through this procedure, then the unit is to be repaired or replaced. Contact Trans-Cal Industries
for further information.
