noske, all correct. I was at that meeting or similar, and was able to discussed some of the issues with Don.
  • GPS is implemented, as and when fitted as a nav position sensor, or with the option of GPS within EGPWS.
  • Upset recovery was progressed, but AFAIR the manufactures/operators did not not want to pay without a mandate; they and the regulators believed (still do) that pilots can be trained for the unexpected.
  • Speed Tape, so right as ever. There was a reluctance to change after Gulfstream and Airbus has designs approved, even though the option to 'invert' the tape was available in several other types (737 / Avro RJ).
  • Auto pull-up was flown and tested as part of the US mil programme post 9/11. The civil development suffered 'lawyer fright', the risk of being sued in the event of a malfunction and hurting unrestrained passengers. The latter, in comparison with other risks and that of EGPWS reliability, has been shown to be unfounded. A FD version was considered, but again manufactures/operators were reluctance to invest in safety without a mandate.
