Happy Thanksgiving to ya'll, This is related to my previous "overweight" post. I want to know if you agree with the following reasoning: Context: you take off over your maximum gross weight, and wonder how your climb speeds and performance are affected. Vy: The AOA corresponding to the best...

A "quad-copter" design with a wing! I would expect this design philosophy to provide higher speeds and reduced energy consumption compared to wingless types. ...

I sometimes cut-n-paste crash victim's names into Google.groups.rec.aviation to see if that person has ever posted here. Too ghoulish? One person's name, about 6 years ago, came up. IIRC, his family was in the plane. With the spate of recent crashes it got me wondering, again: People here...

OK, if i call up approach when airborne and ask for VFR flight following, they'll want to know where I'm going. If i'm following a semi-complex route, on V airways and going from this VOR to that, perhaps turning at an intersection to a different V airway, do they really want to know that? Or...

Over on "alt.binaries.pictures.aviation" someone has posted a terrific, high resolution, nearly head-on shot of the Air Force Thunderbird F-16 ejection sequence from the crash in Idaho a few months ago. It REALLY shows how close the pilot came to hitting the deck before ejecting. It turns out the...

I have an Icom transceiver and have no problems with batteries. I too use the alkaline batteries. Ross Ross Oliver wrote: I recently purchased an Icom A23 Sport handheld transceiver, which uses 6 AA alkaline batteries rather than the rechargable NiCad. I chose the Sport model because I...

When a power setting table shows a "best economy" and "best power" setting for a given power level (say 75%) using a given MP and RPM this is just a starting point, right? Once the MP and RPM has been set and the leaning done, the actual power settings would be more like 78% for best power, and...

My flying training has taken a long time, I guess......... I started flying training in 1990, but lack of time and money meant that I stopped after about 10 hours, before going solo. Last year, my wife bought me a block of lessons for my birthday, and I found that I hadn't forgotten everything. I...

First of all, sorry for crosspost, but I need very good and adequate answer. This is the first time I write on these newsgroups, sorry on my bad english.Because in croatian Internet web pages or gruops has nothing on this issue, I hope that you will help me! I'm a fan of machines, first of all...

Hello FBI surveillance software? Anyway, I am now in possession of one brand new "Jasper" DPSS 5mw laser from bigha.com. That's the same laser used in the recent media hyped incidents at KTEB. I'm going to test the claims that pilots can be visually impaired empirically. (Guess who the pilot...

This question was brought up in another group and never answered. Assume you are flying off the coast of Hawaii and can see an aircraft carrier group in the distance. Is there an airspace classification around it? What's to keep you from buzzing it at 1,000 feet (other than a couple of Phalanx...

Twenty years ago I almost got into flying, I'd even taken my Discovery Flight and was all set to dive in. Then my wife-to-be put the kabosh on it saying it was too much money. Now money isn't so much an issue anymore and I'm all set once again to follow my dream of having my PPL. But, I've heard...

I'm tracking a flight tonight between Boston and Paris. The plane was delayed on the earlier flight leaving Paris, so of course BOS-CDG is delayed too. But here's something strange: It seems that the original flight number was cancelled and a new flight plan was filed with a letter suffix. So...

I need approach plates for the bahamas, but all I could find that is suitable the the jeppesen trip kit for $69.00 and covers the entire carribean. The DOD plates only have Nassau, so that won't work. I need approaches for Treasure Cay and Marsh (RNAV/GPS)specifically. If someone has these,...

So we've been flying our new "Penguin" -- our brand-new 2-place simulator -- during Movie Night at the Inn (see it he http://www.alexisparkinn.com/flight_simulator.htm ), and last night we started "flying" the G1000-equipped Mooney for the first time. No one in the room (and there was...

In the course of trying to understand how a constant speed prop works I came across the following passage in one of the Jeppesen books: "If the throttle is advanced without decreasing the pitch of the prop blades to increase ___ rpm, the manifold pressure increases as the prop mechanism attempts...

FAA Says Hangars No Place For Homebuilders http://www.avweb.com/eletter/archives/101/2872-full.html?ET=avweb:e2872:218609a:&st=email#222534 The FAA says most of the work involved in building an airplane is a "non-aeronautical use" and it has singled out homebuilders in a new proposed policy...

Hi, I am trying to write a formula to compute flight headings. If i use 2 lat/lon i can get a "true course" but due to magnetic variations the true course is not really all that useful, (knowing that my true course is 118deg will not tell me that i should fly 93 deg). What i mean is if i go from...
