Perfectly balanced, as all things should be

At least some of you are probably aware of an activity called wakeboarding. It's like water skiing, except you are on a single, wide board and the idea is to use the wake of the boat to launch you into the air and do various tricks. It's a lot like snowboarding on the water.

Something I discovered today is that there's a technique for adjusting the wake that the boat makes by changing the weight distribution of the boat. This is done by adding weight in the form of ballast to the boat in a particular location so it moves the overall center of gravity forward or backward. There are products available to make this easy. Some are containers for water. Some of those are even shaped to fit more easily into the various locations of the boat, such as the bow. Others are containers for solid material, such as bags of steel shot.

I bring this up because the Beechcraft Musketeer has one very critical difference from a Cessna 172. It has a markedly more narrow C.G. envelope. For example, if I were to take my wife flying with me, and she was in the right front seat, and the fuel tanks were full, the plane would be nose-heavy and outside the envelope. If she were in one of the rear seats, it would be fine. One way of addressing this is to put some weight in the baggage compartment to bring the C.G. rearward. It adds weight but, as long as it's below the maximum, and there aren't any issues with density altitude, runway length, etc., it's still fine.

When I was looking at the plane before purchasing it, the previous owner took me up for a flight to demonstrate how it takes off, handles, and lands. Because of the C.G. envelope, he put about 50 lbs of stuff in the baggage compartment to ensure the plane would be balanced. Although it's not what he used, he mentioned that a lot of Musketeer pilots will use bottles of water or sand bags for this purpose.

I got to thinking about what would work well and a bag of shot came to mind. So I started looking around for something that would work and came upon the bags of shot used to balance boats for wakeboarding. They are available in 25 and 50 lb. sizes so I ordered two 25 lb. bags. I figure I'll just keep them in the plane and take them out if I don't need them for a particular flight. They're compact, and they have handles for easy handling. They also have metal rings so I can fasten them down to make sure they don't leave the baggage compartment.

I've heard that there are also weights available that can be installed in the tail section. I may look into that as a potential longer-term solution since it will require a lot less weight, but these shot bags should work for now.

My engine is so pretty

I went out to the shop today to take a few pictures of my engine and plane before the engine is remounted. The baffling and some other stuff has already been attached to the engine. The engine mount is not back yet. Since the nose gear is attached to the engine mount, the plane is currently sitting on the main gear, and a couple of supports just behind the firewall, and under the tail. Here are a few of the photos I took. The engine looks lovely, to me at any rate, especially since I know those are new cylinders.

Flying when you must

The previous post was titled "Flying when you can." Today the weather was so nice that there was no question about whether or not I'd go up. Today is Saturday, and if you have weather this nice on the weekend, at this time of year, you can't not go flying if it's at all possible. I'll probably go tomorrow, too. I hope so. With the work that was done during and after the annual inspection, my plane is finally fully functional. As far as I know, everything on it works. The intercom is even behaving itself, with a distinct lack of loud static during the last couple of flights. The shop didn't say if they did anything specific to fix it but either they did when I last asked them to take a look at it, or it's somehow sorted itself out. Hopefully it will work just fine, at least until I decide to replace the audio panel with one that has the intercom built in. As noted above, the weather today was absolutely gorgeous. I flew north out of Harvey Field up past...

Night flying

One of the things I've wanted to do since I got current is to go up at night with an instructor for a refresher flight. While I can't do that in my airplane, I can still do it on one of the flight school's planes so I made a reservation for this evening to spend some time with an instructor in a 172. While the weather looked a bit iffy, it was good enough to go flying. I met my instructor at the appointed time, 7:00pm local time. The first thing we did was go out and perform the preflight inspection on the plane while there was sufficient daylight. After that, we spent about half an hour or so in his office going over the things to be aware of when flying at night. Once that was done, we walked out to the plane, got in, started it up, and headed out. We headed north for a while as we discussed the unique aspects of piloting and navigating at night. For example, using the horizon as an attitude reference, and recognizing the presence of poor weather conditions. The weather i...
