great instrument cross checks!!!!!
Chimbu Chuckles, because of the way the ILS was transmitting, the aircraft was getting an onslope signal regardless of where it was. So it was flying some arbitary approach angle which lead to the energy management problems. Presumably the approach gradient was whatever the autopilot happened to give them. I would guess that if the approach had been much steeper they would have caught it quicker. It seems that it was just steep enough to distract them without ringing instant alarm bells.

Chimbu, the report says the Capt was planning to use the level segment between the arc to slow from 220kts flap1 to 180kts flap5 to be at that speed at G/S capture. Approach was armed just after the localiser captured and G/S capture occured almost immediately so they were still doing 220kts at that point, 40kts faster than they had planned to be at capture! Once they started down the hill the speed got up close to the Flap5 limit.
