Thank you, Torgeir. It is really a priviledge to have people like you and others, to answer my questions. I feel much safer knowing you're there, guys. I think the "memory chamber" is also the reason e.g. the Blanik glider I share hangar with, has thermos bottles in the fuselage, not for coffee but to increase this "chamber" for their variometer, isn't it? But, what I was wondering is if the "limited leak" from that chamber goes into the cockpit or back in the static line. If it goes into the cockpit via the body of the instrument, when then connect the VVI at all on the static line? Unless it is a pressurized cockpit, the variation of pressure will happen there, even if it is not equal to the outside pressure. On the other hand, if that "leak" is going back in the static line, it surely influences the other instruments, doesn't it? I mean: If I suck gently the air at the end of the static line, after a few seconds, the pressure will be equal again, won't it? In any case, I'll do as you say, and check that each instrument is working ok, i.e. they are not leaking individually.

And isn't it fun to ask? You chose a (magnetic) heading to fly a track that hopefully puts you on the course that you marked on your map. If you are off course, you change the heading to cause your track to intercept the course you planned and drew on the map. To compute the heading you need to fly to stay on course, you correct heading for compass error, the offset of the earths magnetic poles, and the wind..... You then fly the heading and hopefully the plane tracks the course. Or you just look out the window and "go there". That was fun, but you already got some great correct answers. And you are right too. NATO has not standardized all these terms worldwide, so our definitions may vary. Just like QNH, QNE and QFE. When you get an altimeter setting, you need to know if you are going to land at field elevation above sea level, or zero. We are not standardized on that either. Before Webster standardized words in the US, people wrote things the way they talked in their regions. Davie Crocket went out to walk his "dawg". People in Texas would drill for "erl"... ;-) And they spelled it that way... Well, not "erl". We had dictionaries by then, but you get the idea. (Webster learned over 20 languages while writing his first dictionary.)

You have a diaphram with a closed chamber on both sides. One chamber is connected to the static source. The other is sealed. As the static pressure increases, it pushes the diaphram against the other chamber's steady pressure. As the static pressure decreases, the other chamber's pressure pushes against the diaphram and static pressure on the other side. If there is a small leak in the diaphram, and the static pressure stops changing, the other chamber's pressures will eventually equal the static pressure. Of course the diaphram moves the VSI needle and it only moves from zero when the static pressure changes. It lags behind a little when you level out as the leak pressure catches up to the static pressure. Only enough air moves into the other (memory chamber) to fill it to equal static pressure. It doesn't go anywhere else. If the memory chamber is small, it will only show a leak for a moment until the VSI goes to zero. But you should get a drop in altitude that remains with increased static pressure, or a degrease in altitude that remains with static source suction. It should not show a leak and return to the origional altitude on your altimeter. I recommend using a hose with water in it shaped like a "U" attached to the static source where it would connect to your static vent at the rear of your plane. You raise the hose end a little using gravity to push the water up the "U" a bit toward the static pipe to give more static pressure, or drop the hose a little to produce suction. This keeps you from damaging the instruments with too big a change and you can keep the hose steady for a steady reading. If there is no leak, it should show an increase in altitude with the hose raised, or a decrease in altitude with the hose lowered. The altitude should not return to your start altitude unless there is a leak. Same but opposite direction with static pressure changes for airspeed.

You need 2 "T"'s, 4-90 degree elbows, and a length of straight pipe. If I remember, it is 2" plastic pipe, but you need to check that. It friction slips into the spar ends, but I cut "V"s into the pipe ends to allow for wing fittings, etc. You put a "T" along each pipe between the spar inserts and run a pipe off the "T" outward to be the axis to rotate around. Make stands to your liking with 2x6's, plywood, etc to hold the pipe. Scrap from your SS shipping container can be used here. The whole thing wouldn't cost $20 at most if you have to buy wood, and you get lots of use from it.

Aha! I start to see the light at the end of the tunnel, if you'll excuse my metaphor, Kurt! :-) But then, it is like sucking the air out of a Coke bottle, through a very small hole. You suck on say, a straw, and feel an immediate under-pressure. But then, it diminishes until the rather large volume in the bottle has gone down. You do it again, and again, until the total volume of air, the straw AND the Coke bottle have a low pressure that keeps the tip of your tongue glued on the straw's end. ... Did I mention that you have to drink the Coke first or use an empty bottle? :-) Anyway, if the said memory chamber has some volume, it is then not strange that I see the altimeter and VSI go down after the first suck ... if you follow my drift, partner! :-) Therefore the need to suck several times, unless ... > I recommend using a hose with water in it shaped like > a "U" attached to the static source Excellent idea! I'll do that. Thanks Kurt.
