1900ft at 5 miles is high on any 777's approach. That is a fact!
I'm genuinely interested in this statement. Are you implying that a 777 won't cope with a 3.6/7ish glide slope?
It's about 32,000 feet from the bridge to the aiming point.
Arcsine(1,900/32,000)=3.4 degrees.
Arcsine(2,250/32,000)= about 4 degrees
Can the plane do that or not?
