What am I hearing / seeing

Is he doing acrobatics?

 

To me, it sounds like a T-6 or something similar with somebody learning about prop and throttle. High rpm in fine pitch will sound rather harsh when the rpm increases. I hear it around here once in a while when my wife gets mad at me. I wouldn't worry. Throttle back, go into fine pitch and increase rpm and you can get a nice racket.

 

High wing?
Low wing?
Single engine, twin?
Are you near the runway?
Is this take off, landing, or in-flight?
Altitude? (best guess...)
Same aircraft or many different?

 

We've had a problem with someone doing stunts (stalls, rolls, upside down flying, etc.) and making lots of noise over the lake. He was finally caught.

If he was above minimum altitude and over a lake, I don't see how he could be charged with recklessness. Breaking noise limitations?

 

Under 500 feet.

The noise was not covered by a regulation, but was a peace and quiet annoyance.

 

If he was doing any aerobatics under 500 feet without experience, he needs to have a talk with someone. If he wasn't over any population and was over the lake , he wasn't breaking any FAA rules. If he was apprehended, he did something else. I used to do a few things over Lake Samamish and Lake Washington without a problem.

 

There are hundreds of houses surrounding the lake and lots of boats on the lake.

 

These images don't look right to me. What is the dark outline on the wing in the upper photo? I can't identify the airplane in the lower either.

 

Sheriff has no authority over aircraft.

 

Flight instructor in a Cessna. They spend a lot of time in the air. Shutting off the motor is part of the training.

I also saw a warbird flying very low and slow this morning. Yellow wing tips. Maybe a T-6 or SNJ ?

There have been several types of planes involved. The top photo may have been a bi-plane and you are seeing the wing shadow. Here is another photo on another day closer up that definitely appears to be double wing but of a different color:

Hopefully an engine shutdown never happens, but it's probably best to train for it. Modern aircraft can do some amazing things with a good pilot at the controls.

 

I have never heard of any training where the engine is purposely shut down in flight. Throttled back, yes. But shut off, no. Unless there is some new in the syllabus.

 

When my father and I were taking lessons back in the mid 70's he had an instructor who would shut the engine down. One time, with a different student, it did not re-start. Became a real exercise in picking between beans and corn (this was in rural Ohio). Dad had a different instructor for the remainder of his training.

 

Shutting off the only good engine you have is really dumb.

 

Absolutely. To shut off a hot running engine and let it start gulping in cold air can cause all kinds of problems that do harm to the mechanical innards like bent valves. It can also mess up fuel mixture and feed....carb ice. Total lack of knowledge about how your engine operates if you purposely shut it off in flight.

 

Bob Hoover was really dumb





and shock cooling is a myth

 

Bob Hoover had two engines in his Shrike and comparing him to a normal flight instructor is...

I have seen his show several times, including his P-51D demos, and his dead stick landings. Those were planned events.

 

I did air shows with Bob Hoover and Chuck Lyford, both of whom were flying big liquid cooled Allisons and Merlins when they performed their engine out routines in the P-51 and P-38. The Shrike has two large 6 cylinder fuel injected engines that can also tolerate temperature changes a lot better than smaller air cooled engines. Then there are different procedures for shutting down different air cooled engines and with some engines if they aren't followed you can get cracked cylinder heads and barrels and other problems. So, we're talking apples and oranges. All of the mechanics with whom I worked and all of the old pilots and instructors with whom I flew were talking mythical nonsense , I guess.

 

Well, I guess that I was taught all the wrong stuff by the old folks. After reading some well backed articles, I must have been fooled by some clever Gremlins but the statements do mention that special care should be maintained in cutting and restarting engines.
