Cleaning a 3-way TE probe

In the meantime I plan to get a T fitting and put the LNAV
on the airspeed pitot pressure as being better than nothing and
getting me back up in the air.

Not quite sure what you meant by the above comment. The pitot for the L-Nav
should always be connected to the same pitot port as the airspeed indicator.
If you use the L-Nav for speed-to-fly info, it should come from the same
source as supplied to the airspeed indicator that you fly by. Of course
this is not necessary. You can have L-Nav info based on one pitot reading
and airspeed indicator based on another. But, it would be nice to have the
info correlated. Hopefully both pitot reading would be the same, but, that
is not always true.

Welcome to the insect world, Dr. Jack. I once had the little buggers fill my
hole in one afternoon, as I attended to some routine items on the ship. I
religiously keep the hole covered, now.

You can apply reverse pressure to your pitot, static and TE lines from the
instrument panel. be sure to remove ALL connections to your instruments first.
Then I give each line, short bursts, of compressed air, as I watch the hole for
debris exiting.

Your L-Nav should be on the ships pitot & static system, also check the ASI
calibration page for correct numbers (see manual) the constant tail-wind sounds
like a pitot problem, L-Nav not generating a good TAS, so it must drive in a
big tail wind to make things equal out with the GS its getting fron thr GPS.

Its only October, you got all winter to work on this. Don't you just love a
challenge? :)
