• Curved flight path portions of the search pattern may not display on the MFD or
may display as straight line segments. The center point of the orbit pattern may
also not display on the MFD. CDI steering information will be accurately
displayed.
SINGLE DME OPERATION
If one DME is inoperative and the crew elects to tune both NAVs to the ILS frequency during
approach they should be aware that the VPU may go into DR. This does not affect the accuracy of
other Universal UNS-1Esp sensors. This situation should not occur unless the remaining operational
DME roving channel is unable to receive at least two valid DME signals.
OPERATOR’S MANUAL
For detailed operating information, consult the Universal UNS-1Esp Pilot’s Operating Manual, latest
