"HACKENSACK, N.J. -- An air traffic control manager at Teterboro Airport said the trial flight path for incoming planes -- originally implemented to diminish aircraft noise and avoid Hackensack University Medical Center -- was too much work for pilots and thus abandoned."
"Testing began April 4, 2016, and ran for a continuous six-month period. Simultaneously, pilots had the option of utilizing the flight path that they were accustomed to -- RWY 19, which flies directly over Hackensack Medical Center [and] Prospect Avenue, the most densely populated street in Bergen County -- and other residential neighborhoods.
"That flight path utilizes an instrument landing system, the most common approach utilized by pilots which requires far less work than the quiet visual approach, officials said.
"Over the course of the six-month trial period, only 234 planes utilized the quiet visual approach.... Officials said the manual entry of landing waypoints increases the workload for pilots and requires a lot of 'heads down' time when they are supposed to be flying."
"One of the reasons given for pilots opting not to use the test flight path was waypoints.
"... A charting company removed the coding for waypoints depicted as visual reference points from aircrafts' flight-management system. This made it so pilots would have to input the coding manually mid-flight, causing safety and time concerns....
"The coding was removed due to pilots flying waypoint to waypoint instead of over Route 17."Neither reporter defined "waypoint," which in air navigation is an intermediate point on a route.
