  1. Exactly. Given the same winds and engine rpm, at 1000 ft and 5000 ft the carburetter will be metering in less fuel at 5000 ft than at 1000 ft therefore reducing the consumption. Obviously power is reduced by this, but it will be offset to some extent by a reduction in drag. All of that data is presented in the charts I'm after.It would be a fair bit of work to compile it all, so I suspect it hasn't been done by Jabiru.

    With an 80hp (auto lean) engine you have got to be kidding. Any small difference would not effectively change your endurance so becomes academic & of no use in real terms.

    Just enjoy your flying in a light aircraft without over complicating things for no real gain - IMO keep things simple when nothing gained by making extra calculations.

  2. In reality, hardly worth the trouble.

     

    For a J170 if you plan 15ltrs/hr, 100kts @ 2850-2900rpm the difference achieved will be less then the difference between forecast and actual wind at any alt.

  3. I'm not suggesting that at all, but surely you'd promulgate arrival info earlier than 10 days out? The local families who want to see the clown and balloon twisting show might decide to rock up on the day, but pilots intending to fly in would be planning their arrival weeks before hand.

    Pesky pilots - they probably think it is about aeroplanes, flying & fellowship - not any more.

  4. No landing or overnight fees if you rent the apartment. Not sure about the 100h part but still... I’m only at 30h so I’ve got a bit of time to make it to 100h but very keen to do this.LOT 40 - WHITSUNDAY AIRPORT

     

     

    Enjoy staying in this luxury hangar home during your visit to the Whitsundays. Located on entry to 14, you have the convenience of pushing your aircraft out to the airstrip, a private pool, massive hangar and room to relax in this beautiful hangar home. If you love aviation then this is the home for you, everything you need is here, enjoy cooking a bbq while overlooking family and friends in the pool!

     

    No landing or parking fees during your stay.

     

    Two queen beds, two single beds with two additional fold out singles available.

     

    Minimum two night stay - off peak $500 per night - peak season $550 per night. Complimentary tea and coffee.

    FYI

     

    Whitsunday Airport - Airport Flight Procedures

     

    "Operational requirements mean that visiting pilots must have at least 100 hours in command and obtain the current information as above. The airport is located in a small valley and has a curved approach and departure from each runway and winds can at times be very strong and gusty."

     

    On my last visit landing fees were waived if you purchased fuel.

  5. Not necessarily referring to elected positions, it seems like ground hog day. Maybe some fresh ideas are needed?

    Exactly, the elected positions guide/direct the staff but ONLY when a cross section of members representatives are on the board of directors. An unrepresentative few pushing their own patricular agenda (as a controlling minority) is not healthy at least IMO. Not likely to change in the short term until enough members get upset enough to reflect their "airport opinions" in the voting area.

     

    We have what we voted for and will remain until changed in the short term, for how long is anybody's guess.

     

    Comically enough as predicted before the constitution change vote!

  6. Getting a second check on a 100hrly/annual or a l2 is a waste of time as when someone is dangerous enough to shortcut etc the I am confident that they will also have a mate with the same attitude (including a L2)

     

    Cannot legislate for fools without creating problems and cost for the majority who comply with the tech manual NOW.

  7. Not related to flying so I won't debate the matter but the charge is "in charge of a motor vehicle" - and the defence is "manifested an intentention not not to drive". Plenty of case law on the matter should one really want to find the real answer and equally plenty of hearsay opinions mostly wrong. Best stick to FACT but not IMO a matter for debate here so I will not comment further.

  8. Perhaps some people considering the increased stall speed at 60° should look closer at that statement - the stall speed increases at the square root of the wing loading - not the angle of bank.

     

    At 60° STRAIGHT & LEVEL the wing loading is 2 so the stall speed increases by 1.414 but not in a decending turn where the wing loading is reduced.

     

    One can then go into all depths of maths if it they like but in all realism not helpful to actually flying the aeroplane.

     

    Handy to understand generally but not relevant to actually flying - you do not have time to hit the pause button and do involved calculations.

     

    IMO too detailed to be considered for the average RAA pilot.

  9. Seem to get a few extra knots I believe

    I believe an increase in speed of ? Knots occurs in the 170/160 aircraft. No change in speed observed in my 230 (and another 2 local 230s). I am happy with the prop as such but don't expect a speed increase on a J230.

     

     

  10. I had the opposite experience to Ben, after 30 years in GA (as a CPL) I was "amazed" with what I found in mixing with "some" RAA qualified pilots and their "expert" opinions on everything aviation after gaining my RAA certificate.

     

    One thing that stands out is the large difference between the output from one RAA school to another. The syllabus is not IMO at fault but more the compliance.

     

    In my short period on the board I raised this matter with Jill Baily who agreed but replied that although it is known they are adopting a top down approach to the recognised problem.

     

    I would have thought that efforts (audits etc.) would produce a better result with a bottom up approach to address the shortcomings. I intended to follow up on this matter but the vote to change the constitution put paid to that.

     

    To me a top down approach achieves nothing other then stats to indicate that our schools are compliant - not addressing any shortcomings.

     

    I now sit back and smile - my immediate friends (whether GA or RAA qualified) operate to the same standard and give "some" more space if we happen to be in the same area.

  11. I had one of hanson supporters knock on my door. so i thought this is my chance to ask some hard questions and i would ask the same of any pollie. left or right question where looking after the old homeless power bills and house prices all the day to day things. and all he could say was shorten this shorten that. they are all the sameI rest my case

    More political comment - doesn't anyone respect the rules of this site ?

  12. Everyone has their own political views, and I respect that, but I do not visit a flying site to be subjected to political views of ANYONE. I thought that was established with the other site (which I don't visit) but it comes back here usually by a small select few - is nobody listening to them on the alternative site? Moderators need to crack down on this CRAP.

  13. A 30 degree bank will increase the G-forces, and stall speed, a non-trivial amount. Stalls turning onto final are very rare. But they are a very common cause of fatal accidents.

    How much do you think the stall speed is increased by on a 30° "descending" base turn.

     

    Might be worth a visit to your flying school and brush up a bit of theory before suggesting everyone needs a AH for VFR flying. Get an instructor to take you up with the AH & T&B covered up - it might surprise you.
