Hi All, I was thinking today about the fluid dynamics surrounding a propeller as it moves in a circular motion. It seems that, no matter what the blade angle, there would be a significant amount of energy lost simply by turning the fluid. IOW, even if there were no drag at any point on the...

For years it was apparent that there would be a shortage of ATC controllers due to retirements, but FAA delayed precutting more. Now this: CONTROLLER HIRING PUSH CREATES CLASS STRUGGLE (http://www.avweb.com/eletter/archives/avflash/857-full.html#195087) The FAA's unprecedented recruiting drive...

Here's food for thought. The pilot chose to press on on three engines, and then had to land for refueling ~100 miles short of his transatlantic destination. http://www.latimes.com/news/local/la-me-britair1mar01,1,2497317.story March 1, 2005 By Eric Malnic and Hector Becerra, Times Staff Writers

We've been having a problem with the engines on our Seneca II for awhile now and I wonder if anyone else has any experience with it. The engines are TSIO-360s and if we lean at cruise with about 75% power (typically around 32-in MP) or less to anything over about 1400 EGT (which is still ROP),...

Which is more reliable? Which do you like better?

Hello, New to aviation and I would like to know how to submit a NOTAM. I plan to launch an unmanned free balloon a few months from now with a payload of scientific instruments weighing less than 4lbs. The projected flight-path will take the balloon only through CLASS G and A airspace (and maybe...

When you are flying VFR in good weather, what is your "comfort zone" for altitude (irrespective of regulatory or other restrictions)? At what altitude AGL do you find that you feel a little too close to the ground, and at what altitude MSL do you find that you feel too high for your own comfort? ...

I was wondering what people view as their limitations in terms of wind. I'm talking 172 / Warrior territory here. Clearly this is a personal decision, based on your perceptions of your own skills, the aircraft you are flying, the specific conditions on the day (E.g. how gusty, reports of LLWS &...

Is the following for real or is there a typo? Geese in Class A airspace??? Allen ------------ IDENTIFICATION Regis#: UPS28 Make/Model: B757 Description: B-757 Date: 11/03/2005 Time: 2325

Hello. I'm finishing up my CFI training. My CFI and I went up in a 172 (certified for spins) and tried to get the plane to spin for my spin training. The airplane was loaded properly in the utility category. We could not get the airplane to enter a fully developed spin. It would enter the incipient...

There is little doubt in my mind that the ability to do slow flight at the very edge of stall speed will do more to prevent accidents than 1000 hours of cruise speed flight. Is there anyone here who is proficient that lands their aircraft more than 10kts above stall speed? I teach all my students...

As we all know, you can't carry a passenger unless you are current. But if two pilots get in an aircraft with dual controls, can either of them really be considered a passenger? You can log PIC from either seat. Lets say, I have a PPL but am not current. My best friend has a PPL but is not...

I am a new airplane owner (since May). My mechanic replaced my battery last June. No choices, I figured he bought the one it needed. Just serviced it (added water). It's in a REALLY awkward spot to get at and see inside the cells -- on the floor under the instrument panel of a plane with no doors...

http://www.aso.com/i.aso/AircraftView.jsp?aircraft_id=84399 I flew this yesterday and it was nice (but what the hell do I know) He is asking 105k but Vref says it is worth $113k. That seemed high but again what do I know. Any Mooney owners out there want to give an opinion on the M20J? Thanks in...

Here's a message posted to my blog from the brave Mr "Anonymous": "YOU are the same Dan from Usenet who has the audacity to claim hoew ****ing wonderful of a pilot you are when you don't have your CFI or a plane that is worth a ****?" "Grow the **** up, McCormack. Google GrouperLooser."
