I have a similar background. When I was flying the air carrier aircraft,
the company I worked for had as policy that its crews would report
leaving a previously assigned altitude, whether PD or not.

There reasoning was it removed any possibility of ambiguity.


Where was ambiguity possible?



When there are two options, and there is any doubt as to which is
right (or wrong) exercise the option that has the least cost if wrong.


What is the cost?
