GPS Guided Routes in Alaska – Airways Magazine

0

DALLAS – The United States Federal Aviation Administration (FAA) has published 54 GPS guided routes in Alaska. The route map allows pilots to avoid icing by following direct paths at lower altitudes.

FAA officials announced last month that the 30 new and 24 modified terminal transition routes, known as T-routes, are part of the agency’s Alaska Aviation Safety Initiative.

“Flying in Alaska is unlike any other place in the United States,” said Acting FAA Administrator Billy Nolen. “The T-roads will provide pilots with additional options to safely complete missions in this particularly challenging environment.”

According to FAA officials, pilots use T-routes to travel along particular locations when flying under instrument flight rules (IFR) and using approved Global Positioning System (GPS) equipment. or Global Navigation Satellite System (GNSS).

13 have been activated to date. 20 others should be commissioned in November and December 2022, the others will follow in 2023.

FAA Aviation Safety Initiative in Alaska


In October 2020, the FAA launched the Alaska Aviation Safety Initiative. After a year-long investigation into Alaska’s unique safety challenges, the agency released 11 recommendations last October on how to improve aviation safety in the state. The development of T-Route has been included in these recommendations.

In Alaska, aviation is a way of life and an absolute necessity for much of the state, with 82% of communities only accessible by air. Since the late 1990s, aviation safety in Alaska has improved significantly, and the FAA understands the need to continue to improve aviation safety standards and practices.

The FAA worked with the aviation community on an extensive, year-long investigation into Alaska-specific safety risks. The FAA Alaska Aviation Safety Initiative (FAASI) team has created a comprehensive plan to strengthen aviation safety in Alaska by managing, improving, and implementing new and existing activities.

Officials said the FAA is creating more T-routes to replace low-frequency/medium-frequency (LF/MF) airways by 2025.
