It's the other way around, you need to contact them to be omitted. One possibility for not showing up is lack of nearby receiver coverage

Correct term is Affirmative usually shortened to "Affirm", "Confirm" as Facthinter uses is non standard

I don't doubt the story of honing still being visible at 1500 hours, the plating on 912 Bores is very hard Something I dont think many people notice is the name cast on the cylinders, a very well regarded Italian cylinder manufacturer ...they aint made by Rotax

AoA (Angle of Attack) Indicator Garfly made a usefull thread covering them here...

You'll get solid info on Rotax engines here... https://www.rotax-owner.com/en/forum But what you actually have to adhere to is down to your regulatory regime

The gearbox inspection is at 600 hour if no slipper clutch and 1000hr if you have the slipper. (I believe regular Avgas use will shorten the inspection period to 600hours even with the slipper fitted) Cost is dependent on what condition its found to be in and work/parts it requires, could just be a belleville washer needed or new dogs..etc etc...variable Just what work is actually mandatory is more down to your regulatory system than what rotax stipulates (UL Engines are not certified)

Yes ATIS - Automatic Terminal Information Service, Generaly found only on large airfields with commercial activity in my country, do smaller aerodromes have it in Aus?

If your altimeter is calibrated and correct and you are parked at a spot that has the same elevation as at the centre of the longest runway (or you know for sure elevation at your position) then yes it should match. I fly mostly in and out of farm strips with of course no ATIS so the procedure I adopt is as you mention dial in known elevation before taxiing then check when Im in vicinity of a airport with ATIS that it matches Saying all that, anywhere that has an ATIS is likely to require you speak to them before departure and that info will be given anyway (speaking of UK, though should be same..... I must remember to add that disclaimer)
