Desert Dingo,
Prospector is still unable to accept the Royal Commission Report
Quote:
"Captains of antarctic flights were specifically briefed in 1978 and in 1979 that they were authorised to descend in the McMurdo area to any flight level authorised and approved by the United States air traffic controller "
As against a direct Company order for this flight
Delete all reference in briefing dated 23/10/709. Note that the only let-down procedure available is VMC below FL160(16000ft) to 6000ft as follows:
1. Vis 20 km plus.
2. No snow shower in area.
3. Avoid Mt Erebus area by operating in an arc from 120 degree Grid to 270 degree Grid from McMurdo Field, within 20 nm of TACAN CH 29.
4. Descent to be coordinated with local radar control as they may have other traffic in the area."
When, according to your quote, an invitation from an Air Traffic Controller overides a Company Standing order, then yes, I have trouble accepting A Royal Commission Report.
