How many of you out there do some really serious navs?
Most navs are serious! Rig support 350nm overwater, north of WA (pre GPS) single pilot in a Wessex 60 on a regular basis. Trips across the outback (in a fixed wing: helicopter was too slow) with 400nm legs, no navaids, were nearly as challenging. Even a couple of hundred nm up into NSW at night was a serious nav!
Has anyone ever done a 1 in 60 in the real world?
See all the above.
Or even calculated a ROD/ROC in flight?
Just about every IFR flight would need that, too. Part of normal IF skills, and needed to advise area control of ETA to TOD.
All basic skills, IMO
As for fareastdriver: that's why we had a looker in the back with a doppler plot and lots of nav skills
