Changing selected standing orders
 

I checked the box to select "dive to periscope depth" from the "Aircraft Sighted" interface screen.

However now it so long to get the boat down and my flack gunners nerver fire a shot. Before they would fire a clip or two while I was getting the boat to periscope depth on my own.

My question is: Is thier any way to change this order now that I in place. I checked the box 3 patrols ago and now I appears to be locked in for ever.

Yes. In-game, hit the Esc key (you know, just like you're going to exit the game). One of the clickables is 'Options'. One of the options is to reset the default orders.

Thanks for your help.
