I think by "ENR 1.1 10..." you mean "ENR 1.10 1..."
I'll take the deep dive...
Is my understanding correct that because I am flying to an ALA, I can refer to the GAF for my alternate minima and not provide an alternate given conditions were suitable,
Correct.
if I flew VFR to an airport with an IAP and no TAF (e.g BOM reducing their TAF coverage for CAT D airports) I would be required to provide an alternate?
Incorrect.
My logic (!): Part 91 Plain Engliiis section 10 (page 70). By omission, you are not an IFR flight so the IAP/TAF requirements don't apply. If it doesn't say you can't, then you can!
ENR 1.10 section 1.2.1 doesn't make sense, both because it contradicts the new rules, and second, it contradicts itself:
Forecast information must include a. an aerodrome forecast...
then at the bottom:
...the minimum requirement is a GAF.
AIP ENR 1.1 10.7.1.3 contradicts the new rules as well.
Ref the VFRG page 80:
Where a forecast that is required for a planned destination is not available then you must nominate a destination alternate aerodrome.
You
could say the GAF is your forecast for the destination (which, according to the Part 91 bits, it appears to be [for VFR]), so you don't need to nominate an alternate.
But then, in the next section "Destination alternate not required", the VFRG omits your scenario, where you're going longer than 50nm in good weather. Now if it had said "Destination alternate required when", then it could be made to read better.
the regs are just genuinely ambiguous and conflict.
Correct.
