I am working on my instrument ticket. Learning to fly the 9A by hand
has been enjoyable. Then my instructor said it's time to make the plane
fly the approach on auto pilot. Progress came to a halt.
Trying to learn how to couple the 650 to the HXr and to the AP has been
a major hassle. I have found nowhere to go to read up on this combination.
On GRT, I watched Jerry Morris videos but he is using the GRT AP and
servos. Closest I have come and learned a lot.
I have a toggle switch on the panel that directs the 650 output to either
the EFIS or directly to the AP.
My instructor knows Garmin but nothing about GRT, and he says, rightly,
I have to be able to know exactly what the airplane is going to do when in
the electronics are flying mode.
Friday we took off from KREG on 17 and he wanted me to let the plane fly
the RNAV for 35 to save some time. The feed from 650 going to EFIS.
After takeoff, loaded the approach on the 650, going to vectors and then
hitting EDUYA the IAF. I was level at 2K in the Heading/Altitude mode
on AP on the EFIS. I then armed the AP on the EFIS for the approach
and the EXECUTE button was at bottom of screen. I was slightly NNW of
IAF about 2 mile out. I hit the EXECUTE button and the AP, which was
showing GPSS VS (GPS direction mode) then slightly corrected to head
directly for the IAF. The 650 was calling for a tear drop entry into the
holding pattern for the turn back to final. When plane crossed the IAF,
instead of flying the tear drop it turned LEFT to loop back to the final
approach course. So instructior told me to turn it off. I then said let's
try by feeding the AP directly. Cleared EFIS and 650, flipped switch
to feed AP from 650 directly. Plane then flew a perfect approach to DH
like on rails. We then tryed a second time with the switch to EFIS with
same results as first time. I took some pics of screens on second try.
The shot of the EFIS shows the left hand turn and I brought up the
settings at the bottom. I then saw that even though the settings were
for GNAV and GPSV the top left is showing I am in ENAV!!! HOW???
All the setting say other wise!
These two shots of 650 showing flight plan and map showing it wanted
to fly the tear drop. By the time I took shot of Map page, we had almost
completed the turn to Final.
I have been told several times by GRT that when the 650 is feeding the
EFIS, the EFIS is just a pass through to the AP.
At this point don't know where or what to do next.
Any thoughts, suggestions or what ever would be Greatly Appreciated
at this point.
