Dear Chris,
220 kts. 3° = 5% (standard ILS) 220 * 5 = 1100 Ft/men
220 kts. 15% 220 * 15 = 3300 Ft/min
The protection /limit slope is 15%, not 15° (PROMIN)
The crew displayed that VOR-DME 15% limit as Vs 3300 FT/Min, not the CDA 3.3° they did not want to use.
Are we together now?
Of course they improved the ergonomics and displays, that does not prove it was a factor or cause in the CFIT.A question had emerged, why not do better ? That is the logic of annex 13 recommendations.
