How does the UK military get away with such blatant non-compliance with FM-immunity requirements, yet I had to pay Ł17000 to re-equip 4 light ac to comply?
The UK military is the minority user of UK airspace. They have no excuse whatsoever for non-compliance with FMI requirements.
I've also heard that some think that they can get round the ILS FMI requirements by flying a 'radar monitored ILS' in IMC. OK if it's a PAR, but with SRA only, surely the approach must be terminated and a go-around executed in such a manner that at no time does the ac descend below the associated MDH unless the approach can be completed visually before MDH is reached.
Penny-pinching bean counters - bŁoody well comply with the law of the land and stop hiding behind 'exemptions' beacuse you can't afford to re-equip your few aeroplanes to the same standard as every other ac is required to meet.
