Question

What does a lack of a coded ident on a VOR indicate?

a) Station is undergoing maintenance
b) Aircraft is out of range
c) VOR has experienced a power outage
d) Station is U/S. Gone out of calibration and/or taken offline

Answer 1

A lack of a coded ident on a VOR suggests the station might be undergoing maintenance, experiencing a power outage, or is unserviceable due to calibration issues. A missing ident signals that the VOR is not reliable for navigation.

Step-by-step explanation:

A lack of a coded ident on a VOR (VHF Omnidirectional Range) often indicates that the station is either undergoing maintenance or has been taken out of service, potentially due to calibration issues or a power outage. When a VOR is operational, it transmits a Morse code identifier, which allows pilots to confirm the identity of the navigation aid. If this identifier is not present, it is a signal to pilots that the VOR should not be used for navigation because it may not be providing accurate information.

Here are the options:

• Station is undergoing maintenance
• Aircraft is out of range
• VOR has experienced a power outage
• Station is U/S (Unserviceable). Gone out of calibration and/or taken offline

In context of the available choices, options (a), (c), and (d) could all be valid reasons for the absence of the VOR's coded ident. It is less likely to be due to the aircraft being out of range, because range issues typically result in the loss of the VOR signal altogether, rather than just the coded ident.
