C'mon fellas!! Starting to sound like some sort of Professional Pilot R network..
The reason I mentioned the power/drag curves is the OP was asking for things he could do to prepare and I believe that while understanding where ther aircraft is in its stage of flight is important and having a "feel" for it more so, I know myself that I didn't truley understand what was happening or, more importantly what was about to happen and the consequences of it being mis managed until I got my head around them. More power to go slower you say? Well that makes no sense sorta thing.
As far as standards go, Im happy to say that the "Private" flyers in general seem to be below standard to be dealing with busy RPT/Charter aerodromes. But so was I when I had 20hrs and a RA cert or 55hours and a PPL. Solution!? Scrap the RPL, PPL, and everyone has to do a 200hr CPL with a MECIR so as they have an understanding of the IFR guys.... That's clearly not going to happen and would cripple GA in the flight training sector so we need to deal with it. We are not all at the same standard on the roads either. (Unless you life in BRM then it's a fight for the bottom. )
The only thing that actually bugs me, well two things actually, in order and firstly. Radio calls, I never picked up that AIP till late in training to learn RX and each instructor passed on how he thought how it should be done and that only suited that aerodrome so when I hit the big bad world things were quite different. I don't expect a private guy to be able to recite the AIP but at least have an understanding of what calls are required and what are NOT! I don't need 3 calls per circuit if you're the only one at the aerodrome with no inbound traffic and you're on a busy area CTAF or multicom.
Secondly and most guys do help here which is appreciated. Not giving way or room if you are not to sure about where you are or what sequence will work at an aerodrome, or you get a bit flustered when you hear that there is a C210 BE58 and C402 all inbound in the next 5 min. Now I know this isn't required but a bit of airmanship says that if you don't quite feel comfortable with the traffic to give a bit of space and carry on. Now this might mean as little as if departing, maintain A015 ect till the inbound have arrived rather then try to maintain separation by bearing and altitude or maybe extending upwind why the others do a 3nm final.
Small things like this would mean that while some guys have a lower standard then others, operationally it wouldn't be an issue. Hope that's comes across ok, still earLy here!
Oh and one more!!! Your ETA ISNT! In ten minuites, it's at time xx. Not hard to ad ten min to the current time and makes life a huge amount easier for the guys trying to manage 3 other aircraft on descent by not having to work out your ETA for you :)
