Without time to spare, he was able to maintain an appropriate glide slope and airspeed for landing and was able to determine that the aircraft was capable of landing.
Approaching the "in-close" position during the mishap pass, the pilot overcorrected a slightly above glide slope position with a significant power reduction while simultaneously making a large lineup and nose-down correction.
The steep approach procedures require a glide slope of 5.
In the last few seconds, you have done about all you can do with the first two parameters, so you narrow your focus to an optical glide-slope device on the left side of the ship and make throttle adjustments to keep yourself as perfectly centered on the glide slope as you can.
Steep approaches are classified as those with a glide slope of greater than 4.
Another cockpit gauge shows pilots if they are above or below the glide slope as they descend to the runway.
In the final phase of the simulations, the test team forced errors in the glide slope, speed and line-up to see how quickly the aircraft could make corrections, officials said.
They played down the fact that Guam airport's glide slope indicator, which tells pilots how close they are to the ground, was turned off for repairs when the jumbo came down.
