Perhaps you mean 47 CFR § 22.925 Prohibition on airborne operation of cellular telephones.? Yes, that makes it illegal for everyone to use a cell phone while airborne. That persists because of social pressure, not for technical reasons. It has now been 10 years since this happened: "The Federal...

Unpredictable interference is a concern, but the small planes I fly have few fancy electronics. My phone and tablet computer typically being the most sophisticated electronics on board. As I understand it, Airplane Mode shuts off Cellular, Wifi, Bluetooth, and sometimes even the GPS receiver...

When I pilot a plane I don't turn on airplane mode on my iPhone - I can still receive and make calls, though I've never done either (yet). On commercial flights I turn on airplane mode because they ask. Not because I think it will cause problems with aircraft systems. After all, my iPhone has a...

Fascinating read.

The engine has under 1600 hours since last overhaul. Oil analysis trend looks good to my untrained eyes (attached if interested.) The plane will probably be flown between 100 to 200 hours per year (5 person flying club.) With only a screen the oil changes would be about every 25 hours. My...

Expect to close on the purchase of a 1956 Cessna 172 soon. It has the original Continental O-300 with an oil screen. Was thinking of installing a spin-on oil filter adapter, but not sure of all the pros and cons.

Don't know but curious as to suggested possibilities..

Sonex is working on a two-seat variant of their single seat SubSonex jet. It's designation is JSX-2T and I presumea competitor of the above product. https://www.sonexaircraft.com/subsonex/

Just realized both patents are expired and they contain circuit diagrams. DIY lightning detectors anyone?

I plan to lease a personally owned airplane to an incorporated non-profit flying club for its exclusive use. I've been pondering what needs to be done, if anything, to limit my liability if harm is caused by the airplane while used by a club member. According to 49 U.S. Code § 44112 - Limitation...

A fairing doesn't seem likely to be in a MEL.

One company is after prize money: "Astrobotic Technology inc., commonly referred to as Astrobotic is an American private company that is developing space robotics technology for lunar and planetary missions. It was founded in 2007 by Carnegie Mellon professor Red Whittaker and his associates...

According to locals posting to nextdoor.com a B1 bomber allegedly crashed while landing on the runway at Ellsworth AFB. It caught fire and the 4 crew members safely ejected. Neighbors reported sounds of explosions. None of that info is officially confirmed.

Stagnating economy may have been one possible cause. I did start investigating interest rates and they did spike in the eighties (see attached graph created from https://fred.stlouisfed.org/series/PRIME#) Aircraft being financed would put a crimp on sales during high interest periods. If, as is...

Here's a bit of research I did on the affordability of single engine airplanes from 1956 to 2022. I defined an "affordability" index as the number of years of household income it would take to buy a new Cessna 172 at the introduction price for the year of purchase. The numbers used were NOT...
