  1. I have been given what appears to be a set of plans for a Jodel D11 ("approved by DCA 1968") together with a set of some 24 lesson course notes covering BAK of about the same vintage for a PPl.. There is also a file of correspondence surrounding an attempt to build said aircraft that was apparently discontinued around 1970.

     

    The documents were given to me third hand some ten years ago. The original owner is long deceased. I suspect a great many projects suffer this same fate.

     

    Are these of any interest to anyone?

  2. Ah Yes, GPS assisted collisions.If you are stupid enough to use published waypoints exactly as they are printed then you have lost one potential element of protection against a mid air collision. In other words two rather big holes in the cheese have just aligned.

     

    Your track if you do this will mirror someone else doing the same thing. That means either an overtaking or head on encounter. You can pray for GPS errors to save you but consider, if both of you have the same band receiver (eg. GNS 430) then as you close with the other aircraft the position errors due to instrument accuracy, or error, are potentially going to be identical.

     

    This means that all you have to save you is differing altitudes when you cross. Good luck with that.

     

    I have personally met another aircraft exactly head on - except we were about 500 ft  of altitude apart.

     

    Please use offsets, and not obvious ones either.

  3. I am a bear of very little brain because after  reading through the new CAO 95.55, I fail to understand how the proposed MTOW increase does anything at all  for existing RAA registered aircraft and their pilots. The change does seem to  allow owners and pilots of VH registered  sub 760kg. aircraft to switch to RAA membership without losing access to controlled airspace.

     

    I can’t see where it allows kit built RAA registered aircraft to be reclassified in a higher weight category - ‘lightweight aircraft”. that is apparently needed to get a weight increase. I must be missing something.

     

    ‘It appears as before that there is no access to controlled airspace without a full CASA licence, medical and current BFR ,Kit built aircraft are also specifically excluded.

     

    ‘I guess our leaders can see a way through all this gobbledegook but I can’t.

  4. Flying higher, I am not trying to stir people up. I hope RAA (and you) are right about medical matters.

     

    My reading of the discussion is that Avmed is still quite capable of perverting the UK and American standards into something worse than useless or worse than the current mess. They did that with the "basic class 2".  Just ask the color blind aviation community about Avmed's capacity for deception..

     

    I survived in my career by never assuming that people had my best interests at heart. Any time I hear "don't worry, she'll be right!" my BS detector triggers.

  5. Kyle, as I read 95.55, you ( and I ) will still need an experimental C of A under 21.195A to satisfy the definition of a kit built lightweight aircraft. 

     

    There are currently only 25 people in Australia that are authorised to do this and the SAAA Charge for this  service is at least $700.

     

    RAA in its own right can’t award a C of A - most of the ones I’m aware of are SAAA, and I don’t. see why they would want to  do anything for an RAA member. Their forms are all VH prefix as well.

     

    ‘’There is thus no current way, approved by CASA, for RAA to issue you with any approval beyond 600 kg.

     

    Oh yes, and what happens if you need a medical to drive group G?

     

    At present, you would need to (1) get your kit built aircraft VH registered, which means you need  current PPL to fly it. Then convert it to RAA while keeping the 21.195 Cof A, if CASA will let you.

     

    I fail to understand why this is going to work without even more legislation because RAA has no way of issuing the appropriate C of A..

  6. Waste of time? MTOW Useless?

     

    I hope I’m wrong but From reading the current version of 95.55, I am afraid that the new limit only applies to production aircraft with an existing C of A of some sort. Kit built aircraft already flying under an RAA permit appear to me to be excluded from the weight increase.

     

    The detail is in the definition of “lightweight aircraft” which is the only classification with the 760 kg limit and it has to have some form of C of A - an RAA flight permit is insufficient. 

     

    ‘’This, if accurate, is bizarre because the same kit built aircraft has a higher MTOW if it’s VH registered with SAAA instead of RAA. - Unless RAA can issue a C of A.

     

    ‘’There also appears to be a workaround - 1. Cancel RAA registration. 2. Register as VH with SAAA at the new weight you now have a C of A. .3. Now transfer back to RAA1

     

    ’Can someone please explain where I’m wrong?

  7. Skip, I say again, the ASIC is part of a living, ongoing, counter terror strategy. That is why it requires updating every two years. It’s not about 9/11 or yesterdays threats. it’s for the next one, whatever and whenever that may be. It’s superfluous now but  one day it may be your only way of entering an airport. This much was indicated. I know nothing else about counter terror.

  8. You need to use an approved lithium battery. Rotax has guidance on this matter. There is an Earthx range specifically for experimental aircraft fitted with Rotax engines.

     

    I've attended one house fire started by a newly installed battery. The house was a total loss. The battery model was recalled. You need a solar accredited sparky to do the installation as well.

  9. I use a lithium phosphate battery for three reasons 1. Weight, it saves 10 lb. Using the old $100/lb. rule it’s good value.

     

    2. I get very low self discharge and I can fit a battery that meets the Rotax 912 iS minimum capacity of around 30 min if I lose both alternators.

     

    3. The weight saving nicely offsets the CS prop extra weight.

     

    4 This model is approved by Rotax- it has dual BMSs.

  10. 1. You can buy new drive lugs from Bert Flood.

     

    2. The lugs are a medium interference fit and aren't pressed in but pulled in when you tighten the extension bolts.

     

    The surfaces need to be clean and dry, then apply a little duralac to the lug to prevent corrosion.

     

    3. To remove the old drive lugs, use a suitable M8 machine screw and a washer and tube arrangement to pull them out from the rear, its not rocket science, There is no hammering or brute force involved.
