(Airspeed Indicator)
G'day Everyone ....
Well ,..... it's been 18 (or19) months since I damaged her & pulled her
apart ...... but .............
VH - REB ( Rebel 541R ) now FLYS AGAIN Woo Woo !!!!!
(and the stall with my home made cuffs and VG's is REALLY benign & docile
---------------------------------------------------------------------------------------
Now ...... I need your help people ....
My Airspeed Indicator was just checked (in situ') and is reading 98 - 99%
acurate over it's entire range - ( 20 to 160 knots ) ..... BUT ...
When I test flew her - it consistantly read 12 ish Knots UNDER range in
the air at high speed ...... and at least 10 ish knots OVER as I was
rounding out to land ?!?!?
(I did a bunch of flying on Saturday & Sunday - and, using the GPS over a
multitude of headings & altitudes - acertained that the cruise speed is
actually 100 knots - and
I have BOTH the pitot and the static probe hanging off the front of the
leading edge of the port wing - by about 18" - and about 5 feet out from
the root
My own suspicions are :
1) Problem with the static air side of the system - somewhere ?!?
2) False readings from the high angle of attack she now can achieve
3) pixie dust caught in my pitot tubes ... (just kidding)
Anyone got any suggestions about WHERE to / how to set up the static
system / inlet etc, etc .... ???
Thanks
Rick "Biggus" Harper
