    Grounding while fueling

    What is the correct way to provide bonding?

    Grounding while fueling

    I don't know Ed. I remember hearing it but don't know the reason. That is what I use. I see some of the pilots here using the other places and explain that they are not grounds (at least I don't think they are). I tell them to use the exhaust pipe.

    No fuel crossfeed.

    I have 4 CTLS in the hangar. Two 2008, one 2009 and one 2010. None of the tanks ever equalize. 15 gallons in one tank and 3 in the other and the can sit for weeks and never equalize. I don't understand it but wish I could. If you have somewhat full tanks and jack up one side, gas will flow out the vent. This I understand but why don't the tanks equal out when sitting level?

    Grounding while fueling

    What is the best place to attach ground wire while fueling. The main wheels and tie down rings on the wings are places I see pilots using but on the CTLS I don't think those places go to ground. I have also heard people say it is not a good idea to use the exhaust pipe. It seems to me that on the CTLS the easiest is the exhaust pipe or the nose wheel. What do you use?
  5. Two questions I have, maybe you can help. Two different planes but same avionics in both. I used to have a wind speed arrow that was on the D120. Somebody messed around and now it is gone. I was told this was controlled by the D100. I have searched in both the D100 and D120 trying to find it without success. Anyone know how to do it? The next one is the stall horn setting. It goes off on one of the planes on take off and way too soon on landing. We don't use this plane for check rides because the examiner would hear it and it is just too soon. Can't find that setting either. Thanks

    Air speed gauge

    Not sure what brand it says Flight Design on the face.

    Air speed gauge

    The round air speed gauge shows 40kt when on the ground and builds from there when flying? Is there an adjustment or what can I replace it with. Digital air speed is fine and if we are at 100Kts the round one shows 140 kt

    We are getting close to the deadline. What is the solution for the CTLS? UAvionix on the wingtip won't work and now I have found out that the taillight unit won't work either. Apparently the carbon fibre blocks the wing tip version and makes it unreliable. I tried to install the tail version and the mounting holes are different. The taillight on the CTLS uses angled mounting holes and are further apart than the UAvionix unit. The unit needs to be mounted with the fin on it vertical and using the mounting holes would have it a about a 41 degree angle. They have no plans on revising the mounting bracket to make it work. I have one I was going to test for them but now I need to start looking at something else.

    Brake stuck

    It seems that the best way for you to understand the way it works is for you to disassemble it all and get the complete picture. It is not difficult and will be easy to understand. I question why you are not having an A&P do this for you. If you don't understand the mechanics you may cause yourself a pick problem.

    Brake stuck

    Don't just take the pads out and replace. Remove the wheel and disassemble everything. Clean it all and repack the wheel bearings. Replace the pads and reassemble.

    Brake stuck

    Those are Marc brakes from Italy

    Brake stuck

    Many time it is because the pads are very worn. It can also be the caliper is so dirty things hang up. I would start with those and see if it is all in good shape.

    Fuel caps

    My vents are in the wing tips. We sometimes do have the tanks pretty full but even then it shouldn't happen

    Fuel caps

    I checked several times and it is not the seal around the ring. This is happening on all 4 CTLS's we have and it is worse on some.

    Fuel caps

    Who has the secret to fixing leaking fuel caps? I have replace both the large and small o rings and tried adjusting several times but still they leak. Short of not filling the tanks so full I don't know what else to do.
