Phil Squares, or anyone else with ‘information’ (re #1222), would you care to comment on the document
Celebrating TAWS ‘Saves’ and perhaps indicate which incident or what factors might relate to this accident.
I note similarities in the procedure being a NPA. The approach chart has no table of altitude vs distance to assist with a continuous descent, and no advisory VS. There are two beacons shown for the approach, and a third for the missed approach; how are these depicted by the FMS/EFIS ND.
VOR not used for the approach?
There is no ground-based distance information, thus consider how the onboard position might be calculated. Does the FMS have GPS input in this aircraft? If only IRS/DME what position updating might be available on a trans-African flight?
Was this aircraft fitted with EGPWS or TAWS (T2CAS). If EGPWS did it require the FMS position or use an embedded GPS (not available for navigation).
Note that all of these features precede any GA event and subsequent handling issues which appear to have an unwarranted focus of attention.
