correct as is Autopilot Radar Altitude Hold

[skywalker22]

Does the autopilot Radar Altitude Hold (RALT) works as it has to, based on the video bellow?

As you can see, autopilot can go uphill from a horizontal, straight path, also can  go over crest, downhill, but when its pointing downhill, it just cannot climb any longer. As you can see it crashes. Is that how it should suppose to work?

RALT is not intended as a low-level terrain masking mode. It couples to the radar altimeter, which can see the ground right below the aircraft, but is not a terrain following radar. It's not nearly as fancy as a dedicated system like the F-15E has with the LANTRIN TFR Pod, which can look ahead as well as straight down. 

 

You crashed because the autopilot exceeded it's pitch authority and disengaged. Notice BALT disappears from the ADV line on the Left DDI (also, your wings are unlocked).

Hi,

 

this is correct as is, there is no terrain following in our hornet.
