Yep, I’ve been using LaPook’s information to shore up some of the ‘what does this mean’ questions I’ve had while going through the last edition of the Flight Navigator’s Handbook. I’ve heard of those types of simulator, but I don’t know of one that exists at present. I should look for one.
Stellarium is great software. I’m using it to help calibrate the sextant I have – which is a frustrating endeavor, but at least I have the required bristol wrenches now.
