    Had an issue with Avplan recently: I have Avplan on an iPad Mini and an iPhone. The iPad is the cellular model but a sim card is not installed. Wanted to show a friend so the night before I opened it up (at home so connected to the internet (via wifi) on the iPad to make sure all was up to date. All good. The next day (not connected to the internet) I was unable to access it – it gave an error - said that my subscription had expired yet I had 6 months to go. Tried it connected to the internet via my iPhone as well, didn’t help. Much later in the day later it worked. Same issue with the iPhone - good connection to the internet at all times. Avplan support responded: "We were experiencing some website issues which caused these issues." My response - "I would’ve thought that my iPad not being connected to the internet would’ve been especially immune to such website issues – perhaps it did something in the background before I left home. Glad it didn’t happen on my trip to Qld recently – sorry, but .." I am going to dump Avplan, I wonder if OzRunways can suffer from the same problem? As for mounting an EFB on a control yoke - refer to the CAAP on the subject.

    Inverted?

    He confirmed today that he is turning up.

    It will be interesting to hear what he has to say when he gives a talk to us at Moorabbin Airport soon. Royal Aeronautical Society - Melbourne Branch

    I initially had a comment about different readings on the g meters between the front and back cockpits but edited it out as I wanted to quote a reference.Here's a good one: http://atlantis-press.com/php/download_paper.php?id=2599 A Method for Correcting The Error in Indicated Normal Acceleration Due to G-Sensor Location. SAE PAPER 700222 (Loading conditions measured during aerobatic maneuvers in flight test to determine structural design requirements for aerobatic-type aircraft) has some typical data for Pitts and Decathlon but the document is not available for free online. See extract below. The bottom line is that the G meter must be located very close to the aircraft CG.

    .... or tailplane icing ... or a "moose stall" .....After one accident report I tried to replicate the scenario - yep, an aeroplane with a very benign stall in all situations suddenly pitched extreme nose down. Added a warning in the flight manual about combinations of flap, power and airspeed to avoid, especially in a turn. Excellent advice, but I have had to do it (and I am sure that others here have had to do it also).Whenever I do any analysis of flying qualities I put the axes through the CG, not only by convention but it just makes the equations and arithmetic more simple. Velocities and accelerations etc are therefore defined wrt those axes through the CG. Back seat of a Pitts S-2 is way behind the CG so quite a different feeling in snap rolls compared to a Pitts S-1. Aeroplane going up but, initially, the rear seat is going down.

    Worth a visit to Watts Bridge if something interesting is happening: Watts Bridge Memorial Airfield - Calendar of Events otherwise I'm happy with the beach and the pool.

    Suggest reading the relevant chapters of Book #1 at FLY BETTER...... or page 2 of the smaller document: Spin notes at http://www.flightlab.net/Flightlab.net/Download_Course_Notes.html A common explanation is simply that the wing centre of pressure moves aft at the stall - seems to be based on the excellent book Aerodynamics for Naval Aviators - see that bit about "... as stall occurs, the drop in suction near the leading edge cause the c.p. to move aft." but that's not true of all aerofoils e.g. NACA 63-415. In any case, the data presented is from two-dimensional wind tunnel tests etc so doesn't really address the real situation of a three-dimensional wing, especially with flow separation originating from the inboard root.

    In little aeroplanes too per CASR Part 61.

    We can get it right now. I have a US pilot certificate, just need to fly a US registered airplane here.

    At the Qld Aerobatic Championships, Watts Bridge, last weekend.
  13. djpacro
    Good stuff! I passed by yesterday on my way north. Will wave as I fly over on my way home on Monday.
  14. djpacro
    Tocumwal and Lilydale will do it, both in Eurofox.

    Ran out??! Suggest that you don't advertise it as "all you can eat" next time.

    Also check out http://www.aeroacademy.com.au/ I'd visit all three and have a look around, talk to insructors and students. Go away and think then return to one for a trial instructional flight. I know people who have learnt at each, all gave good reviews. Curtis use Citabrias for ab initio. The other two at Bankstown use the Robin. At AAA you would get your aerobatic endorsement with your RPL, Red Baron possibly does the same. NSW Aerobatic Championships in September at Narromine and Qld Aerobatic Championships end of this month at Watts Bridge. AAA aircraft and pilots will be at both.

    Fuel: Shell cards generally not made available and their bowsers largely changed to CC, see http://www.shell.com/content/dam/shell-new/local/country/aus/downloads/aviation/au-aviation-locationguide2012.pdf BP: http://www.bp.com/content/dam/bp-country/en_au/products-services/air-bp/2015-16-Air-BP-Refuelling-Guide.pdf Aero Refuellers run many bowsers: http://www.ksgroup.com.au/aero/aerocontact

    Once the hail and snow passed it was time to do some aerobatics.
  20. djpacro
    with CASA's new definition of aerobatics clearly a breach of a variety of sections of Part 61. despite fine words from time to time, CASA is obligated to comply with the law. What was that: aerobatics in an airliner, etc etc etc not VMC - lots and lots of penalty points = $$$$$ per degree of overbank?

    TVSA?

    Yep, need a class 2 medical.

    I'd suggest starting with USA's Part 61 rules on the subject.
  25. djpacro
    doesn't take much searching on youtube to see who on the dark side have been doing aerobatics nope, RPL is all that is required (under the old rules a GFPT could get an aerobatic endorsement too). quite a few aerobatic airplanes less than 600 kg, some two-seaters.I'd keep my next Pitts (the LSA variant of course) on the USA register and fly it here on my USA pilot certificate.
