Simultaneously reducing speed and height in the 777.
1. 1900ft at 5 miles is high on any 777's approach. That is a fact!
Whether the 5 mile point is 280ft above a 3deg slope or 400ft above the 300ft/mile formula used by most pilots is a moot point. The NTSB report will probably comment on that.
2. If the airplane is on the glideslope, being 43 knots above Vref at 180 knots at 5 miles might be OK. However, the combination of 280'-400' above the glideslope and 43 knots above Vref is a dilemma. Experienced 777 pilots will have skill and techniques to resolve it, however a trainee may not. When he is being supervised by a new training captain, the cheese holes are getting nicely lined up.
I invite other 777 pilots to tell us how they prefer to deal with this situation.
