To the editor:
As a retired major airline captain with type ratings in the Boeing 727, 747-100 and 747-SP, as well as the Lockheed L-1011-500 and Douglas DC-8, I would like to endorse the noise abatement procedures proposed by Tom Babcock, a representative of Islanders Concerned about Aircraft Issues.
These well thought-out procedures are not only effective in mitigating noise, but are very cost effective for the airlines involved (as evidenced by the findings of Southwest Airlines). We used these same "Keep 'em high" procedures more than 30 years ago.
We called them "Profile Descent" procedures. Essentially, we would try to plan our descents from our cruise altitude with the engines in idle thrust (throttles fully closed). The goal was to not have to advance the throttles until 500 feet above the ground, about midway between the "Outer Marker" and the runway, during our final approach. Due to traffic and wind conditions, this was not always possible, but a good flexible goal to work from.
