  • Certification is via NORSEE for Class I and Class II aircraft, non-pressurized aircraft.  
  • Installation is typically a Minor alteration, log book entry only; the installer makes the final determination in this regard.
  • Important Note: NORSEE allows installation *in addition to* existing, required instruments in the cockpit.  We are working guidance on how to potentially replace a legacy, analog clock which may be considered a required instrument in some aircraft.  (GPS units often have a clock that meets FAR requirements.)
