BEags,
you would think a 180x0 wouldn't be co-alt wouldn't you?!
Not the EA6 drivers!! They'd go for a 180x0 co-alt almost every time in Telic I!
Used to get a bit twitchy whenever I'd see the Tacan counting down at 800Kts or so!!
As for SM... I think he's high on drugs or something; certainly not in the real world at any rate!
