    Having observed many ASI being tested in the hangar I don't believe there is any lag. It would happen if there is a significant but not complete blockage in the pitot line. The reason there is no lag is because there is no flow, it is pressure in a closed system. Squeeze the hand pump on the test rig connected to the pitot tube and the needle will immediately jump up 10-20 knots and stay there if no leakage. Lag could also be caused by problems with the mechanism as facthunter said. This is why we test them in the hangar.

    Flying into wind and experiencing a rapid reduction in head wind due to gusting is no different than flying down wind and experiencing a rapid increase in tail wind due to gusting. Gusting can also be vertical resulting in an instant increase or decrease in angle of attack. It matters not which way you fly. The down wind myth will live on.

    Yes differential braking would have been available. The ATSB will not investigate.

    A paper WAC is 552 wide by 443 high. This is just the map part in southern Australia, they get bigger as you go north?

    Read the ATSB report. I wonder about the cost of the ATSB report versus the Coroner's report and there worth for pilots and the general public. The coroner appears to have little knowledge of aviation. https://www.atsb.gov.au/publications/investigation_reports/2018/aair/ao-2018-078/

    No oil will be lost if the breather pipe is not disrupted. The open end of the breather is way above the oil level now.

    Elevator trim tab is in a fair nose down position, not what you would expect for landing with one pob. Maybe a go round.

    This has a good graphic of the traffic with the radio calls in real time at about the six minute mark. Not sure if the c152 said I am going around or you go around in the final transmission. I will always maintain having traffic on a screen greatly improves situational awareness and only takes a glance now and then.

    Some days it is good to have a nosewheel.

    It is fire season over there now so it will be ok.😁

    That is the rule in Australia. This is like something we see on dashcam, neither party will yield. Sad and stupid.

    From the FlightAware data it looks like the cessna 340 making a straight in approach to runway 20 hit the cessna 152 on final for 20 at about 400-500 feet agl. The 340 was maintaining 190knots in a steady descent.

    It would seem unlikely that the student froze on the controls. He had been flying for 10 years and had 250 hours (that is an hour every second weekend over those years so not nothing). He had also previously taken an aerobatic trial flight in a Decathlon. He wanted to do the aerobatic endorsement in the C150. Would the student do the first spin or would the instructor demonstrate and talk through the procedure?

    It has to centred behind the pilot looking out front. If we can see attitude, airspeed, controls, weather and what was happening leading up to any upset there would be little doubt as to how it all went down.

    GAMI say their unleaded G100ul fuel will work in all the current fleet and provide the same level of detonation protection. The problem will be lawyers. If a turbocharged Continental pops a cylinder off the block when running on a fuel the the engine was not originality certified for it will be open season for anyone in the firing line. The fact that these engines and other makes have had the same failure modes running on 100LL will be irrelevant in court.

    The thing is students just need the basics in the beginning. There is enough to learn at the start without adding stalls, spins, spiral dives and inverted flight. If you learn the basic concepts correctly you will not be in a stall, spin, spiral dive or inverted flight unless that is what you intended.

    Vne is the speed that must not be exceeded in smooth air with very minimal control inputs, it is 180knots for an RV6 and 150knots for a Beech 23. Va is max maneuvering speed, the speed at which full or abrupt control inputs can be made. There is no limit on multiple control inputs in the Beech 23 POH but common sense should prevail. It is only 118knots for the RV6 and the Beech23. This would suggest that the Beech 23 is just as strong as the RV6, not necessarily so because it is all about stall speed protection of the airframe and effectiveness of controls. The Beech has a higher stall speed. Know your aircraft, read the Pilots Operating Handbook or flight manual.

    Ausfly 22 is on 15-17 September. Last held in 2019 due covid, was a raging drought with dust storms and a mega summer of bush fires to follow. This year it will be perfect with green grass everywhere. Narromine is a great spot with excellent facilities. Hope to see many of you there.

    Final report from ATSB. https://www.atsb.gov.au/publications/investigation_reports/2021/aair/ao-2021-025/

    I agree there is no risk involved in spinning certified aircraft when done by appropriately trained pilots. I have done spins. Chances of recovery from a spin in the circuit by a pilot that has had a few spin lessons would be almost zero? Let's face it no one accidentally spins in cruise flight. If the the spin training makes pilots more aware of the risks of stalling in the the circuit then yes there is some benefit. The same result could be achieved by all student pilots being made to watch 20 mins of stall spin crashes as part of their licence. Stall/ spinning to the ground = death

    I make the comment above because going out and practicing spin recovery in any aircraft to make GA flying safer makes about as much sense as shutting down two engines in a RAAF 707. Learning spin recovery for your own personal reasons, I am ok with that.
  22. Thruster88
    Is not spinning the aircraft guaranteed to work every time?

    A history article about Gordon Bedson and the Resurgam. https://meadowsfrisky.co.uk/pages/gordon-bedson-aviation

    Ok if you can PM some pics or post them here I will decide if it is worth the effort. If there is someone closer who wants it that is ok as well.
  25. Thruster88
    If it was closer I would come and get it to preserve, a bit of early aussie ultralight history. Not sure if there is one in the Holbrook collection. I bought a set of plans from Gordon but never started the build.
