SIMPLE GROUND TEST IS NOT A COMPLETE TEST OF ALL ALTITUDES. IF ANY QUESTION
EXISTS ABOUT THE SUITABILITY OF AN INSTALLATION, PERFORM A FLIGHT TEST IN VFR
CONDITIONS A REVIEW THE RA ALTITUDE READOUT ON THE RA MAINTENANCE PAGE TO
VERIFY THE DATA MATCHES THE PILOT’S RADAR ALTIMETER INDICATOR THROUGHOUT
THE ENTIRE USEABLE RANGE OF 0-2000' OR 0-2500'.
