Re: Run-in and angle test

You are probably OK with that. You seldom run that long at full throttle at

Hi Newbie, As the other guys have said, pointing the plane downwards will uncover the clunk in the tank when the fuel gets low enough and/or the angle gets great enough. When the fuel in the clunk line is used up, the engine will stop. The clunk should *never* fall forward.....doing so will likely kink the fuel line and stop the flow anyway, resulting in the same thing.....engine stopping. A covered vent line won't make any difference......there will be pressure coming from your muffler and will keep the line from filling up anyway.

When you're flying, it's not appropriate to have the throttle wide open when you're on a downline, unless you're aiming for the dirt :-) Just about any engine will maintain fuel in the line for quite a long time at idle, particularly if the clunk is not totally uncovered the whole time. As has been already said, you'd have to be *quite* high to be able to maintain a full throttle, high angle descent for 30 seconds :-)

It normally goes something like this:

Unless you've got a really tight ship which is designed for speed, you just don't do it :-)

Good luck and good flying to you!
