    Before using any radio navigation aid it should be positively identified by listening to the morse code identifier. VOR/DMEs transmit the VOR ident 3 times followed by the DME ident (a higher pitch) once.

    If you don’t receive the DME ident by listening to the audio from your DME receiver, you should not trust any indication on the DME. The same obviously applies to the VOR ident also.

    Hi Omar,

    I think, perhaps, that we should mention that the VOR/DME station is two separate navigational aids in one. As such, there are two signals that are transmitted from the station. One for the VOR and the other for the DME.

    As Andy said, you should positively identify each signal separately by morse code as a confirmation that you have tuned in the correct receiver.

    You tune the VOR and the DME the same time by tuning in the VOR frequency. The DME receiver sees which frequency is selected and finds its corresponding frequency in a table, of sorts.
