also, descent tables for ILS glideslopes can be approximated by using ground speed IN KNOTS time 5 for descent rate in FPM.
I remember the changeover...hated it then...happy about it now.
also, wasn't it "the high and the mighty" where the navigator makes a mistake in converting miles to knots and screws up things?
