    Aircraft theft?

    Another alternative is to get realistic looking photos of worthless avionics and photoshop them into a print you can fix in place over the radio stack. If it looks like junk when the thief looks inside with a flashlight, they're less likely to open the door for a closer inspection.

    GPS = DME

    Typically, yes. Most if not all (certainly all in current production) IFR GPSs have provision for approach data which in the case of an enroute only IFR GPS is for monitoring and situational use only. In addition, virtually all of the enroute only status is the result of installation...

    GPS = DME

    And depending on the AFM supplement you must either have a current DB or have verified the location accuracy of any waypoints you're referencing for distance.

    KX-155 voltage change

    Interesting. I checked the install manual and like you said, it says 28VDC for the power input. But the maintenance manual clearly says that there's a switching power supply which will work with 11-30VDC and the lighting input can be wired for 14 or 28v. I wonder if they designed it for both...

    Bose A20 Problems

    It's possible that the terminals on your batteries are oxidized and therefor not conducting well. I'd expect that a different set of batteries would cure this as would taking a pencil eraser and rubbing the ends of each battery till they shine. OTOH there could be a poor connection inside the...

    KX-155 voltage change

    Actually, AFaIK the KX155A/165A navcoms will work on both voltages without any changes to the radio or tray connections. The "non A" KX155/165 radios come in two different configurations, one for 14V and one for 28V and there's no (legal) way to convert from one to the other. The wiring...

    Power transmission question???

    You sure they're capacitors? They're normally rectangular in shape and connected across the phases with relatively small gauge wires along with fuses and disconnects. Anything round is likely to be voltage compensation, or switchgear (e.g. sectorizers). If they are caps there's the a good...

    O2 Refill Cost

    There's some good info about building your own O2 cascade here: http://csobeech.com/Oxygen-Fill-System.html There are several important things to consider: 1) Any part of the system that can come into contact with high pressure O2 has to be super clean. 2) All parts of the high pressure...

    Where / what is the fuel manifold?

    Given the after crash fire I'm surprised they could even find the fuel manifold, let alone discover contamination inside it. The materials described in the report sound like something you'd get with ethanol enhanced autogas stored for an extended period. There is a fine particle filter well...

    IFR rating questions

    IMO there nothing wrong with the accelerated training (e.g. 10 day course). I believe that anyone reasonably capable of learning new things can become at least as competent with that kind of training as they would be if they spread the training over several months. And AFaIK the total time...

    Quantum Leap In Weather Forecasting

    Check out the initial weather products for GOES-R (I highlighted the ones I think will be most beneficial to aviation). There are even more planned for the future. Baseline Products Advanced Baseline Imager (ABI) Aerosol Detection (Including Smoke and Dust) Aerosol Optical Depth (AOD) Clear...

    how likely am I to make this vfr only flight? (Weather)

    Things have gotten better the last several years and these days with some limitations the 3-5 day forecasts (e.g. MOV/MEX) are fairly accurate. Of course there are still some colossal failures there (this applies to 24 hr forecasts as well) it's common for the conditions to be close with some...

    how likely am I to make this vfr only flight? (Weather)

    Just an ambiguous sequencing of words. I think he meant "also the visibility around Jax looks iffy".

    Risk vs Experience?

    There is a world of difference between actual IFR (especially during departure and arrival) and flying with foggles (simulated IMC) and IMO the latter is insufficient for gaining and maintaining competency. The experience difference includes among other things: 1) Making the decision to miss...

    Partial power loss

    Just to be clear, as long as an engine is turning whether due to combustion or windmilling, moving the throttle will have a significant effect on manifold pressure. And if the RPM remains within the governing range (CS prop) the RPM won't hardly vary so the only way to confirm a total power...

    Partial power loss

    Unlikely unless there were obvious signs of prior valve sticking or perhaps if the engine was exhibiting "morning sickness" when the mechanic ran it.

    ADS-B out simple ???

    AFaIK there is no scheduled requirement for ADS-B out for typical GA piston airplanes in any country other than the US. Mexico has indicated that they MAY require it above 10k MSL but there's no firm date and Canada definitely isn't planning on implementing such a requirement although they do...

    Gas (on most full tank)

    My airplane (B55) requires use of the main tanks for takeoffs and landings. I often want to run from the aux tanks as long as possible to retain as much fuel in the mains as possible in case I can't get fuel after landing. As a result I often switch tanks a few minutes before landing and I've...
