Perhaps the AAIB guy didn't come across so clearly, or the "dog ate his homework." The below research document is long and technical, but the very first sentence will do: "Not until the 1980's was i
I have the David Clark ANR model, which is pretty good, and also the ANR kit I installed in an old Peltor headset. A bit different flavor of active noise reduction, but just as satisfactory, and the
If that was an exact quote, the AAIB representative may have been winging it, or "the dog ate his homework." The below research paper is long and technical, but the first sentence is in plain Englis
There are specialty coatings which conduct electricity, but metallic paints as we know them do not. The coating would have to conduct as well as metal, as even small resistance translates to serious
Not that statistics convince everyone nor both genders equally, :-), but checking my Excel data of U.S. homebuilt accidents 1998-2002, 0-40 airframe hours: No structural or control failures or in-fl
Both above questions are covered in detail in Hoerner's companion books on "Fluid Dynamic Lift" and "Fluid Dynamic Drag". As a practical matter, the thickness of the trailing edge on Europa's airfoi
Indeed. For its O-320 engine, Lycoming graphs various stuff vs. mixture control setting. EGT varies by 350 F-degrees, between full rich and the bottom edge of best-economy range. However, % of power
I think Graham may have it nailed, as the Bing adjusts the venturi plunger also with ref to float chamber pressure. This may be ignorant analysis, but on Lycomings you don't have to go too high befo
Good example of where to use a pullable breaker. If used as a switch, the Potter& Brumfield W23 is rated for 10,000 cycles, similar to others. BTW re OV, the Rotax regulator schematic I now have tell
Can't argue with that, :-), but one rationale is that if the electrical sys must be shut off, you'd still be able to trim. However, for the 914, one fuel pump needs juice. If you don't even have that
I have only the one, plus the internal photos, which you shared with me; nothing independent of that. [Nerdy tech stuff follows] By clever I meant it's an SCR shunt regulator, but they don't use a br
I think it's somewhat moot as to how much material can be removed, since leaving maximum "floor space" is handy to neatly route and mount things. My access panel is 8" x 10.5", just about enough for
The Aeroflash units do not meet FAA's current intensity requirements for the strobes. Whether or not they are legal in homebuilts is a fuzzy area. Part 91 permits night flight only with "approved" l
I interpreted the manual to mean, by changing the piston cups to the ones supplied, automotive DOT brake fluid is not used, but rather the Mil-H-6060 red stuff. At least the latter has not caused an
Boy, that's not very complimentary to an FAA inspector...lighting has nothing to do with IFR. It's actually irrelevant what the inspector inspects. The wording of the actual operating limitations con
Well it depends upon a "fudge factor" re the width of the copper strip you're using. According to Jim Weir's book, if 12mm or so wide, then 515mm should peak at 126mHz, roughly mid-band; 490 at 133 m
Sure can have an effect on tuning, but worth noting that tuning the antenna will not likely mitigate the effect on radiation pattern caused by nearby metal, especially near the tips. To this end, the
There's no exception for homebuilts; the test must be done "as installed" (or quickie checked after re-installation if both xponder/encoder bench checked); but for Mode C and VFR, it should be a simp
Sure, except the most practical consideration should be ease of access for battery replacement. Statistically, they're about as useful as a piece of lead, but to the extent the ELT would be handy so
