SFLY - i like your perseverance
- so lets follow your suggested way and imagine we would like to fly best gliding speed ie closer to Vref
How could it be achieved (let us know if you see any other way):
I understand that we are talking about last 20 seconds of flight, right from the moment when the crew has realized that there is really no thrust available (some 3..4 secs after second attempt to add full thrust), with the speed already well below Vref (currently 115kt=59m/sec) and the nose quite high (8deg), clearly below intended GP (300ft=91m above ground), F30, gear down, ac weight about 200tons, with current vertical speed of 600ft/min(=3m/sec) - with this speed our max time in the air would be less than 30 sec:
so to reach Vref we need to accelerate the plane, the best way is to use some existing potential energy to gain vertical speed and than use wings to change it into horizontal speed: not to get into too much teory lets look how long it took and much speed was gained when finaly PF lowered the nose: within 8 sec the plain gained 1kt (sic) and the vertical speed has doubled ! If he would have lowered the nose more he would have gained more speed - but would he have time to get back to level flight?
SFLY be reasonable - would you really like to fly the plane using this strategy?
And look what the crew did: they used whatever kinetic energy was there to stay as high and for as long as possible. At the last moment they went for speed to regain ac maneuverability and just landed (not crashed).
Actually it is the same trick all young pilots instinctively try to do when get below ILS and forget to use the engine throttle
