A few things:
In the descent phase, the distance to the selected flight level is always shown as 1 and the time to selected level is the current time
“Retard” callout occurs at 20ft RA and continues until the wheels make contact with the ground. I was under the impression that the callouts are supposed to stop once the thrust levers have been brought back to idle
Occasionally when established on the ILS, the managed speed won’t reduce to Vapp and stays high forcing me to use selected speed. I haven’t been able to consistently replicate this
