Lochaven , C,C, very useful when trying to acknowledge 'Addis , Addis' and getting 'Bombay , Bombay' on HF... Shouting does seem to help !
Dug out old licences , and have R/T [restricted] on PPL '71 , CPL/IR '73, and ATPL/IR '77 up to '89 issue . '99 issue [R] removed !
We must have done HF theory in ATPL ground exams , but was in '72. But was using HF from '86 in charter 732s. Inc. T9, Speedbird , Portishead , Stockholm , and 'Architect' for Ops Normal on a GIB run. Never formally trained , just on the job .
Kanga , don't think Nat tracks are 10nm apart ; if only because a turnback radius at altitude and M.8+ is best part of 10nm ..Think they came from 120nm[Nav.] to 60nm , and now probably 30nm . And not GPS dependent , but I retired 12 yrs ago .
VC10s started INS training in '75 , Tristars refitted in 76-77ish , triple INS . Last 744 without GPS was about 14 yrs ago . Mandated as a cheap fix after a BMED problem near Addis . Most long haul had Triple INS , but Lufty chartered in 73s with ETOPS to do business class across the pond . They likely only had Dual IRS [ INS with DME update ] , as standard fit in a 73 is dual. I believe our boy said A320 series have triple .
Gaznav ...With hat , coat , and door , and not wanting to stir the hornets nest .. , SS was fun as a P2 and as good a follower as leader .
