The REAL reason for ANT mode was to enable MANUAL DF with those sets that had rotating loops, either electronic or manual.. .Flew B707's years ago with this feature...and it was REQUIRED for the type rating (IR) on this aircraft (if equipment was fitted) at one time. . .The younger guys could never see the reason for this....but hey, what do the young guys know anyway?. .Some in AirBus aircraft have a hard time finding the end of the runway ....without the pictorial display, never mind ADF.... <img src="eek.gif" border="0">
