Chris,

Good points.

I'm hoping you're in MDI when you're doing this.
Do you limit rapids, and turn the F/R over-ride down before you get
close?

This brings up an issue to consider for control writers: Just what
can be done to increase operator safety in this type of "human
intervention needed" situation? Thoughts, anyone?

(and before someone says "use a probe routine"; besides that!)
