What to do if Honeywell Primus 880 fails?
- JJames ChenAug 16, 2025
If the Honeywell Radar fails, it is currently inoperable and should be repaired or replaced when possible.
What to do if Honeywell Primus 880 fails?
If the Honeywell Radar fails, it is currently inoperable and should be repaired or replaced when possible.
What to do if Honeywell Primus 880 shows a caution?
If the Honeywell Radar displays a caution, a failure has been detected that might compromise the calibration accuracy. In this case, use information from the radar for advisory purposes only.
What to do if the XMIT switch is off on Honeywell Primus 880 Radar?
If the XMIT switch located on the RTA of the Honeywell Radar is off, this disables the transmitter. Check the switch at the next opportunity.
What to do if the SCAN switch is off on Honeywell Radar?
If the SCAN SWITCH located on the RTA of the Honeywell Radar is off, it will disable the antenna scan. Check the switch when possible.
What to do if there is no autotilt on Honeywell Primus 880?
If there is no autotilt on the Honeywell Radar, no altitude information is available to make the altitude compensated tilt calculation. Have the system checked when possible.
What to do if Honeywell Radar shows 'Spoking likely'?
If the Honeywell Radar indicates 'Spoking likely', a problem has been detected that may cause spoking to occur. Have the system checked when possible.
What does 'Stab uncal' mean on Honeywell Radar?
If the Honeywell Radar shows 'Stab uncal', an error in the antenna positioning system has been detected. Have the RTA checked when possible.
What does 'Turb uncal' mean on Honeywell Radar?
If the Honeywell Radar displays 'Turb uncal', a problem has been detected with the turbulence detection hardware. Have the RTA checked when possible.
What does 'Tilt uncal' mean on Honeywell Primus 880?
If the Honeywell Radar shows 'Tilt uncal', an error in the antenna position system has been detected. Have the RTA checked when possible.
What does 'Picture uncal' mean on Honeywell Radar?
If the Honeywell Radar displays 'Picture uncal', radar functions are okay, but receiver calibration is degraded. Have the RTA checked when possible.
