Hi b

Ordering chief to recharge batteries will CTD.

This is why you need to keep the commands to simple orders.
Recharge the batteries order is "Propulsion re-charge".

And I have difficulties ordering a new course anywhere in the 200 to 260 range.

This is because the the app does not always handle the figure 2 in the way that you say it and may even action a different command to the one you ordered.
Try it like this: "set new course Two > Zero > Zero" in a raised voice emphasizing on each digit.

There are a lot of commands that work perfectly well without any problems.
The speech recognition manual of orders is essential if you want to keep away from ctd's.
