No. The agreement made was that from about 1997, the FM band would be expanded. The reason for giving away the protection was that it was expected that technology such as MLS would remove the requirement for ILS.
Unfortunately, technology did not go as expected and the solution was to require instalation of filters on current technology equipment.

Englishal,
So we may as well rip out all our Nav gear and bung it in the bin according to you
No you could have a cheap easy to install filter fitted and then your equipment would be FM immune.

Fuji/IO540,
Just because the CAA does not require certain equipment to be carried and be serviceable in Class G airspace it does not not not mean that they are saying it is OK to rely on equipment that does not meet the required standard.
The CAA does not set any standard for some required items in aircraft. Do you think that you could safely claim that the elastoplast stuffed into the seat pocket is the first aid kit.......or that the bottle you peed in was the fire extinguisher?
If the DME was labled as "unreliable" could you use it to complete an approach in IMC? NO. and that goes for FAA/CAA/JAA or any other authority. For not FM immune read unreliable. No mention of airspace there!
Of course ther will always be the idiots who fly with U/S equipment and rely on unreliable fuel gauges among other things.
