Whilst it is entirely appropriate that public transport commercial operations should have a clearly defined fuel policy, applying a similar blanket policy to private light aircraft operations is not.
When flying on my PPL I mostly operate out of an airfield with three runways, with numerous farm strips nearby, several other GA airfields in the vicinity and ultimately a landing distance requirement that would allow me to make a precautionary landing in almost any field I choose. My fuel gauge is direct reading and I know the burn rate and re-measure it frequently. If flying in the local area VFR on a CAVOK day, there is approximately zero chance of me having to utilise so much reserve fuel. If flying visual circuits at my home field, which take about 4 minutes each, why must I stop when I have 30 minutes fuel remaining? In my previous job, flying military helicopters, we routinely operated down to a minimum landing fuel equivalent to 5 minutes. It needed a fair bit of mental dead reckoning, planning and judgement but it worked.
I would rather have the freedom to use my own common sense and airmanship to choose my own minimum fuel appropriate to the nature of the flight I am undertaking, rather than have an arbitrary figure (designed for a different type of operation altogether) imposed on me.
Incidentally, when flying cross-country I normally choose to keep 1 hour fuel up my sleeve. I think I am quite capable of making these decisions myself without EASA deciding for me.
