Based on the FR24 CSV data
-
(best approximation, due to periodicity and latency of recorded data)
-
- 251 IAS out of FL100
- 240 during descent, give or take
- 236 IAS at 2,000'
- ~215 IAS on tarmac, skipping down to 191 IAS
- recording a minimum of 173 IAS, 200' AGL into the GA
With that speed over the threshold, I believe the crew would never have received a
TOO LOW GEAR warning during the first approach; they would have received
TOO LOW TERRAIN instead (or another mode if that would have priority). I can see how a crew would discard the latter GPWS warning as being erroneous/nuisance when approaching a runway in VMC, especially a crew that had already lost their situational awareness due to extreme (probably self-induced) tunnel-vision.
Here's the mode 4a envelope.
