Hi! I was told by my mechanic to only pull the prop handle until I could audibly hear a slight pitch change to establish that it was working. However, the aircraft manual says it should be cycled completely, and on a cold engine three times to make sure oil is applied to the governor, or...

I'm talking about where the prop stops when I shut down the engine. What would cause a 2-blade, constant speed prop on a Lyc. O-360 to suddenly begin stopping in a different position than it had every time for the last 3 years? My prop has always stopped parallel to the pavement until last night,...

When I heard this on the news, I assumed this happened at one of the MKE area airports, but it was actually in someone's back yard. http://www.jsonline.com/news/metro/sep04/262562.asp -- Ben C-172 - N13258 @ 87Y

Anyone else here ever experience one? How did yours happen? Mine have been ag related and hit ground, rocks, birds, and ? Ever throw off a piece of the prop blade? I lost a piece during climbout of a jungle strip in the Amazon in a C-185. Managed to dead stick it back without any further damage but...

I note that the Baron (and presumably other twins) has a prop sync switch that somehow synchronizes the prop speeds on both engines. From recordings I've heard of the interior noise of the aircraft, it does sound as though props that are just slightly out of sync can produce a very irritating...

I've been taught to set the prop to high RPM on final, but I don't like this very much because then, when I run my checklist for the first time on downwind, I have to leave one item "open." So what's wrong with doing it on downwind? (This in a Cherokee 6 or and Arrow) It seems to work fine, does...

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...

Thrust from a propeller drops as speed increases to a theoretical zero. When this happens, what is providing the thrust to overcome drag? The forward momentum of the aircraft? If so, is it a case of the speed very slightly and imperceptibly dipping below the zero thrust speed, getting a little...

When performing off airport helicopter operations in controlled airspace what is the proper radio procedures/calls when taking off after a few hours on the ground? Should I just call with my position, stating i am off airport requesting take off clearance? Thanks Richard

Several pilots found themselves in a debate at our field yesterday. The issue is weather it is safer to move the propeller on a (parked) aircraft in the direction of usual engine rotation, or opposite usual rotation. This is assuming that the propeller needs to move for some reason. The...

The Steve Fossett Airmans Search Project Yah know, it seems a pitiful thing indeed, that the great fraternity of his fellow airman have been unsuccessful in their search for their intrepid fellow, Steve Fossett. Initially those in authority directed the search and rescue operations immediately...

I just discovered that the ADDs weather site (US) is looking for comments on their proposed new user interface for winds and temperatures aloft. If you have a moment, take the new interface for a test drive and provide them with your feedback (mail link is at top of...

If one uses the Cessna 377 Skymaster as an example, it's pretty clear a pusher prop is more efficient than one pulling. The data seems mixed though on q tip props -- any leads as to where there may be quantative data? What I found suggested the extra length of the prop might just as well go to...

Hi! Anyone got one of these? Comments? I have the Surecheck TPAS 110 device, and I'm looking on upgrading. The Sqawk code display looks like a great idea! Good for askeing ATC about location of threats. Does it work well? All comments welcome. Also, if anyone wants to buy my TPAS cheap, let me...
