Could someone advise me whether the UK CAA conducted a Regulatory Impact Assessment on the impact of not filing a difference to ICAO FM Immunity requirements? What cost estimate was assumed for an owner to make an existing privately-owned aircraft compliant with FMI? Did the Wise Ones at the CAA take into account the cost of replacing perfectly good VHF transceivers and VOR/ILS receivers with new 'FM immune' equipment? Or was it a case of the usual rubber-stamping of regulations without any thought for GA? As it's an election year, perhaps it's time for another letter or several to Mullin?
Ah - the hell with it. I'm going to e-mail him right now!

AC-DC, the AIC on the subject refers queries to the CAA Directorate of Airspace Policy, Surveillance and Spectrum Management. I will confirm precisely which body is responsible for the acceptance of the FMI compliance requirements described in the AIC and ask whether a RIA was carried out prior to the requirements being adopted in the UK.
Our group engineering representative sorted things out. The previous radios seemed pretty modern to me (only been in the group for 18 months) and I believe were exchanged for new all singing all dancing black boxes. I have the instructions for the new unit to hand now... it seems that it is a "Narco Electronics MK12+TSO NAV/COM. Not an expert in this field but I am happy to report that they seem to do the job,
ac-dc you probably dont like narco becuse the quality is not up to that of the bendix/king units but they are much cheaper so i gess you get what you pay for.
As to filters for FMI at that moment the only units that have an approved filter are the king KNS80 and KNS81 ,i am told that avionics mobile are near to getting one approved for most units but i have seen no in service date yet ,i hope that this good idea gets the all clear from the CAA soon.
I think we'll be going AC-DC's route, Garmin 430 favoured at moment, but looking at £8K fitted!!!!!!! How did you do it Beagler? Plus does it have 8.33kHz spacing??
A & C I have an all Narco panel (other than the audio panel) and can not complain about the quality, but still don't like them.
DOC 400 Wait, don't rush, I have a MUCH better quote as well as low one for King 165A. At this point of time I do not want to talk to much but after contructing the shop I will email you if you entered one. It will not take more than 2 weeks.
A & C Can you please advice when the filters be approved? I know that for privet cat. there is no need for 2 FM Immune sets but it is nice to have. Thanks.
As i understand it avionics mobile have got all the technical problems fixed with the filter but the makers of the radios are objecting on the grounds that THEY have not approved the filter for use with the equipment that they have made a product liability thing i think. or perhaps the sales of new radios has some thing to do with it !
I am about to fit a KX165A to my aircraft but if you are 12v you will need a converter to 28v ,i had a very low quote for this equipment from a well known discount outfit up north who seemed un aware of this fact and i think that they could not do it for the price. The 165A also needs some wire changes at the plug and is not a "slide in"replacement for the 165. The garmin GNS430 also requirs the converter this should cost about $500.
It seems that the three of us will fit new avionics. Lets join forces and go to the same shop as a group and try to push the price down. Regarding the mistake don't hold your breath, there is always a way out, ' Sorry, out of stock, Sorry, new price list.... To the moment I have very low quotes for the GNS430+ GI106A and King KA 165A+KI206.

Just had a vintage KX170B replaced by a KX155A with a fine new OBS display. The new one is VERY NICE. For £5k installed, I suppose it should be. 28 volt, but no problems for all that.
But what a screwup that thousands of aircraft have to spend thousands of quid on new radios, because some bureaucrat was asleep on the job!
K.J I don’t know if I should do it or not, but you have overpaid. I have few quotes by now. The one for the KX155A with KI204 is below £4000 and the one for the KX165A with the 8.33khz. (there are 2 models) and the KI206 is below £4.5k. Speak with your shop and try to get something back. There can be difference in price, but not 20%. AC-DC
P.S All prices are fitted and loged. NO extra to pay!

Our Airways equipped Arrow (2 x VOR, 2 x Comms- well3 x comms actually) can of course now no longer be used airways till FM Immune stuff is fitted. I understand that in private cat only 1 x comm and 1 x nav needs to be FM immune. Can anyone give me the official reference document stating the FM immune regs: I only seem to be getting half the picture from various forums and I want to keep the cost down. Not interested in fancy GPS fixed stuff, as most members of the group have hand held GPS; merely the cheapest possible like for like swap (but to include 760 channels and 8.33 hz spacing if possible.
