Shot two practice GPS approaches with safety pilot today in the RV10, first was LPV approach and second was LP +V approach. I am running V16 software and for these two approaches I was hand flying using the Flight Director (FD) and the servo's were NOT engaged. The IFR navigator is Garmin 175. I typically fly approaches at 100 knots, no flaps.
I have not really seen these issues in cruise flight using AP.
First, my approach flying skills are in definite need of improvement and this may be a contributing factor to what I am seeing as I was weaving back and forth across the approach course due to my poor IFR flying skills.
Within about 1/2 mile of the runway the safety pilot is telling me I am way off course. I am tracking rock solid on the FD (it is not commanding any turns) but the XTE on the HSI is showing me off course and visual confirmation out the windshield shows me about 100+ yards left of runway centerline.
I am thinking the response rate for errors on the FD are not happening quick enough...almost like the due to lag time it is getting out of phase or slow to respond
I am going to refly these approaches tomorrow with AP servos engaged and see if I can duplicate the condition.
Doe this sound symptomatic of needing up increase one of the following
- Roll Sensitivity
- Roll Gain
- Roll Gain Limit
- XTE Gain
- XTE Dot Gain
Thx
