    Plane loaded with drugs makes emergency landing on Southern California highway

    If you make an emergency landing, they're gonna poke around the plane. Not sure about the legality of that. When I made my forced landing, while I was talking to the cops out near the road they went through the plane and dumped all my bags out, I never did find some of the small items that...

    Swift 100R vs 100LL

    Back when UL first came out for cars, we were told that it would be cheaper "because they didn't have to put lead in it." Yeah, right.

    Safety; rules vs freedoms

    Being in the air at 40,000' is a pretty darn dangerous place to be, too, but we've developed technology to deal with it. The average person accepts that technology has made it safe to be there, and (incorrectly, in this case) assumes that technology will offer the same protection in a...

    If a plane were weightless...

    I didn't say people understood Bernoulli when they mentioned the word. The problem is people conflate Bernoulli with the incorrect "equal transit time" theory. C'mon, you know you're not supposed to give the correct answer right away... :D

    If a plane were weightless...

    Yes True, but rounding that curved surface makes the air speed up, causing a pressure drop... according to Bernoulli. It's only one specific example of Bernoulli's theorem, of course, but it's the one most people are thinking of when trying to explain wing lift. Next, we can discuss whether a...

    If a plane were weightless...

    Bernoulli's theorem describes the pressure changes as a fluid (air) flows over a curved surface. That happens any time the blimp is moving. If the blimp has a nonzero AOA, there is a side (or up/down) force created. As I said earlier, blimps usually fly a bit heavy and use aerodynamic lift to...

    If a plane were weightless...

    Bernoulli and Newton aren't in conflict; they're just different math to describe the same thing. If the aircraft is weightless but not massless (if gravity was switched off), then it moves according to the net aerodynamic force... trim for zero lift for level flight, lose speed in a dive...

    Another highway landing

    It varies from state to state and road to road, from completely forbidden to anything goes. It also depends on the presence and/or attitude of law enforcement. The FAA has no rules about it. I knew of a guy who made an emergency landing on the Garden State Parkway (NJ) who got a ticket for...

    Nan Chang CJ-6A mid-air LA County

    When I crashed my Starduster the news reported it as a "Cessna-type bi-wing".

    Nan Chang CJ-6A mid-air LA County

    Formation gone bad, most likely. If you look at the photos it looks like one plane had a chewed up prop and the other had a chewed up tail.

    Please help out a dad

    They were prescribing Ritalin to bored kids then too, but without today's computerized medical databases, lots of pilot applicants conveniently "forgot" about it.

    Aviation Etiquette

    And keep your radio on-- and listen to it-- if you're running up or doing other stuff while you're #1 for takeoff at an uncontrolled field, so you can hear if the guy behind you asks if you're ready to go or if it's OK to cut in front of you. Keep your radio calls short and concise, especially...

    Seek input on buying a LSA

    That sounds like poor piloting technique. The CT stalls at 35 knots; driving it onto the ground at 55 is a recipe for damaging the plane.

    foreign student damages 10 planes

    Wow. Not the first time a wealthy foreign student has discovered that daddy's money won't buy a pilot certificate in the US, but this is over the top. When I was learning to fly there was a student who was some kind of African prince who did solo, but then violated all kinds of regulations...

    Why would avionics backlighting pulse?

    Does it do it on the ground when the engine isn't running (just running off the battery)?

    Location reporting in magnetic or true?

    Every time I've entered class D airspace in the past 15 years (admittedly rarely) they've asked me to ident, I presume they have a feed from a nearby radar facility. And every time, my response has been "negative transponder".

    Considering a RV-6A But.......

    That may (just speculating here) just reflect the experience level of RV owners in general. I'd guess that low time pilots / first time aircraft owners are more likely to buy a standard certified aircraft. My first plane was certified (Taylorcraft), but every airplane I've owned since then has...
