    SKyecho imperfections

    Glen, I just checked about 15 approaches to the farm in the RV on fr24. My driveway is on the map, it seems like accuracy of SkyEcho2 is better than 10-20 metres coming over the tree line at the house.

     

    Is the altitude transmitted taken from the barometric or gps source?

    Thruster SG85 Aileron Drop

    Hi Guys,

    I refurbished my Thruster 10-1312, SG85 and flying it.

    BTW, it is for sale at "Aviation Clasifieds"........

     

    How much is the Aileron Drop, IF ANY, that is the question !

     

    I have no experience it this, but the aeroplane is sort of not happy sometimes, me too.

    Washout was done very carefully at 30mm both wings.

    It feels like it has more than one equilibrium in balace straight and level flight and it is looking for it.

     

    Kind Regards Tony (Milan) Vlasak

    Should be no aileron drop. I had a t84 from 1985 to 1990 and thought it was a great aircraft, then upgraded to a t500 two seat which I still have. Bought a T85 last year, it is a lot different to fly, controls seem "loose" compared to the later t500. There is a lot of adverse aileron yaw in all Thrusters. They have high drag and low inertia especially the single seat model. Loose skins on the tail can make them behave strangely.

    Looks like the SR23 will be arriving some time around spring.

     

    How did the following aircraft on final for touch n go not see there was an aircraft already on the runway? 

    It most likely happened like this one, one aircraft above the other, neither pilot would be able to see the other aircraft due to structure. Look at the propeller slashes in the roof of the cirrus, nothing on the tail, both aircraft travelling at same speed, scary stuff.

    Fuel Tank Sealing

    Thanks Thruster

     

    This will be a very small job (fitting a new fuel sensor flange), so I was hoping for something  little less costly ($62 US + on costs is pretty scary)

    If it leaks with an inferior product and you have to do it again $62us will seem cheap. CJ aerospace in Sydney should have it in stock.

    Expensive way of making a point. Not too valid since he decided it in the first place and you might have made more enquiries and ruled it out in the first place. Also It may only be valid once as the "word" gets around as it does in these things. . I'm a bit wary of setting up these Tests for students as it doesn't really tell you how the student will behave if you're not there. He/She might think Gee this is a bit much but HE must think I'm up to it so that's a pat on my back and press on where you wouldn't have normally   There's also the expectation that he'll take over IF needed.  Nev

    If the student did the research and ruled the strip out that would be a good outcome. 

    If the student did the research and like Rossk had a look and made a good decision that is a good outcome. 

    If the student did the research, flew an accurate approach (airspeed)  and hit the desired touch down spot that is a good outcome. 

     

    Better to learn all this with an instructor that is prepared to teach for the real world.

     

    It is easy to become complacent landing at a big wide very long strip like Cowra, at my farm strip in the RV or Musketeer with a 70knot approach speed and a narrow strip accuracy is required.

    windmilling prop RPM and water in float bowls

    in AUS/NZ General Discussion

    Does anyone know what the windmilling prop RPM will be for a Cherokee in best glide at WOT setting. (IE minimum intake restriction likely results in higher windmilling speed).

     

    Reason for question. In the case of water in the lines, how long does it take after changing tanks to ingest all the water through the engine, and given the low vapour pressure of water, will it even be effectively pulled into the intake system  at all ?  or will it just fill the float bowl and stop moving ?

     

    The 1/4 ID lines is only 31.7mL per meter. say a 1.3m worth from the fuel switch = 41mL, or at 7000mL/hour =  21 seconds. 

     

    Great minds think alike. After listening to the Archer pod cast I wondered would water in the carb bowl be able to be sucked thru the carb jets to clear after changing to a good tank.

     

    I have my doubts water was the problem in this case, on the PA-28 the drains are correctly located at the lowest point and there is x? amount of unusable fuel. Why did the engine not fail when that tank was initially selected if water of a very significant amount was present? 

     

    One possible solution to clear water from the carb of a lycoming would be to pump the throttle. The accelerator pump should?  pump fluid of any viscosity.

     

    Prop will continue to windmill around 1000-1200 at best glide, my guess

    A worthwhile interview with pilot Michelle who is very honest about what they could have done differently after the engine started surging.

    Notably, it didn't run an oil filter either. Just a screen. The bearings were ALUTIN not very tolerant of dirt. Nev

    The o-320 lycoming in my Musketeer only has the brass screen, it is very fine. Much easier to check for metal contamination the the paper filters. It is on track to make TBO.

    How reliable are engines?

    in Engines and Props

    Posted · Edited by Thruster88

    Anyone really interested in aircraft engine reliability should check out the findings of the ATSB 

    https://www.atsb.gov.au/aviation-investigation-reports in regarding the Van's RV fleet in Australia. About 600 aircraft that owners love and fly regularly. Most lycoming and some Rotax 912. Just search Van's and Vans at the ATSB site. My take is these engines are very reliable when operated correctly.  

     

    The other accidents listed not involving engine failure are a good insight into why planes crash.

    You'll hear about that when someone causes a death or serious injury. It'll be a complaining thread too; not enough insurance to cover the legal bills and the claim awarded to the injured.

    I think there have been plenty of potential test cases,  accidents,  since the RAAus "insurance" began. Start date anyone?
