GPS LPV approaches and STec 20/30
Asked by: snu164 1792 views Aircraft Systems, Instrument Rating
I am going to fly a cross country in an airplane equipped with an STec 20/30. I am used to GFC 500 and STec 55x. I anticipate flying an instrument approach in IMC at my destination and would prefer to use the AP to reduce my workload. However, I am proficient and current in hand flying approaches.
The manual for the 20/30 states to couple the AP to the navigator and set it in Hi Trk mode which is simple enough. In this configuration, will I be able to deselect the altitude hold so I have pitch control of the airplane for my descent? Or will my pitch get locked as it does with some other autopilots?
