Twice in 2 days I've filed VFR flight plans only to have FSS unable to find them when I called on radio after takeoff. One was filed through Duats at 9PM for noon next day (and left at noon). The other was filed with a briefer at Terre Haute at 10PM for 8AM next day (and left on time). In both...

I'm posting on behalf of my father. My father has been flying a friend's older 172. The 172 was recently flown on a 8-hour round trip. During this trip, the plan burned 3-quarts of oil. On return, a compression check was performed. All came back with 75's or better. A check for leaks did...

Hello, I have a 59 Bellanca Cruisemaster that has a Mitchell Executive autopilot in it. To engage the autopilot, you push in a knob on the left side of the panel just left of the vsi and below the ai. When engaged it would roll left at about a 20 degree bank, so I adjusted the autopilot trim knob...

Reviewing some of the old posts on rec.aviation.owning, it appears that the conventional wisdom is that mixing of the gases is ok. What I foresee is that I can get 80 at my home field, but will need to top off or completely fill up with 100LL as I go along. Is this truly ok? Are people still...

I have a maintenance question. I read somewhere that the mixture control should not bottom-out against the firewall when full rich, as the pilot would not be able to tell if the full-rich position was achieved, or if the knob just hit the firewall stop. However, I'm wondering if this is just a...

Still getting to know my new baby (1990 TB-20, normally aspirated 250hp Lycoming IO-540). I imagine my question here must apply to most non-turbo, non-FADEC pistons (though I gather there's some sort of altitude compensator on some airplanes' engines?). I live in Colorado, which means routine...

In everyone's observation, what is the typical difference between the indicated altimeter reading with current pressure setting and the altitude reported by mode c transponder. It seems mine always has a discrepancy of 100', sometimes 200' compared to what ATC shows. Just wondering if it needs...

Howdy, I have an Aeromech 8140B20 encoding altimeter with a KT76 transponder. Mode C is intermittent with ATC. Is it more than likely this is an altimeter problem or transponder problem? Sometimes when it is not reporting, i cycle the transponder off then back on and it starts reporting again....

Hello, I've noticed during a flight the other day to Columbus that our Mode C was reading high... by about 250 feet. The altimeter seems to be indicating fine as on the ground, with the correct altimeter setting, it shows the correct altitude. As well, flying the ILS, i make a habit to check the...

There has been talk of making Mode S a requirement sometime in the future. Our transponder is giving trouble again. Does it make any sense to consider putting in a Mode S transponder now, if we have to replace ours? We can get a yellow-tagged Mode C transponder or even a new exchange from...

I am the proud owner of a new $5000.00 mode S transponder. I just took my first long trip with it, and I began to wonder if ATC sees any difference on their radar screen with Mode S. As you know, Mode S transmits your aircraft ID as well as your assigned code and altitude. I did notice that...

My club has started thinking about putting Mode-S transponders in our aircraft (3 Archers, 2 Arrows, 2 Bonanzas), to take advantage of traffic advisory information. Does anybody here have Mode-S in their plane now? Do you make use of the traffic info? How well does it work? How easy is it to...

Anyone know about AMR@D propeller tip mods and Vgs mod for a Cherokee 140. Pros and cons?

Folks, I have a C-182 with an auto-fuel STC, which I've been operating on Mogas (along with an occasional fill of 100LL) for several years. Mogas being unavailable at my home airport, I use a pair of 6 gallon Gerry cans (plastic) to transport the fuel from a local gas station to...

Delete Morgan County UT and Chreighton NE from the mogas list. Jim

Yesterday I noticed that we had pumped more than 5000 gallons of mogas through the Mighty Grape. This represents something like 60 complete fills (our plane has four gas tanks, totaling 84 gallons), and around 350 hours of flight time over the last 2.5 years. (See:...

We have a 1964 Cessna 172E with a Continental 0-300D. It has the AutoGas STC, but we've never used anything but 100LL. We've had some lead deposits and a stuck valve last spring. With the rising cost of 100LL at our airport, I'm looking at starting to use 87 Unleaded auto gas. Is there a...

This was a little fun quiz that was circulated on a type specific email list a few days ago. It was authored by George Braly of Advanced Pilot Seminars, and principle of GAMI. If you're familiar with George, you know he backs everything up with HARD DATA obtained from his own research. In a...

Hi all, I'm want to replace the windows in my airplane and want to make my own. I've got an oven, piece of plexiglas and the old window. Are there any good websites with information on how to do this without killing myself? Thanks
