OM u/s

Hi all,

Tried to do a search on here but to no avail.

Quick question: say you are flying an ILS DME with the DME inop, the inop table says you have to have either DME or a radial or radar etc, or any other means to independently establish the position of the OM.

Is it legal to use FMS/GPS to determine the position, especially if the OM is coded. For example AMS, all points, FAF and OM, are coded with EH waypoints.

In other words, is the FMS updated by GPS a legal way to independently establish a position according to JAR/EASA inop table.

Thanks
