What are T and Q-routes?

What are T and Q-routes?

ENR 3.3 Area Navigation (RNAV) Routes

  • Q-routes are available for use by RNAV equipped aircraft between 18,000 feet MSL and FL 450 inclusive.
  • T-routes are available for use by GPS or GPS/WAAS equipped aircraft from 1,200 feet above the surface (or in some instances higher) up to but not including 18,000 feet MSL.

What is ay route in aviation?

Aircraft flying Y-routes will typically be within signal coverage of U.S. ground navigation facilities and ATC radar. Actual signal reception and radar detection are a function of aircraft altitude. The majority of Y-routes exist only in the upper altitude structure, i.e., Class A offshore airspace.

What is rnav2?

RNAV 1 refers to a navigational system that has less than 1 mile system error over 95% of the flight, or words of similar effect. RNAV 2 refers respectively to a 2 mile error 95% of the time. DME/DME RNAV, inertial nav, etc may not meet this spec.

What is a Tk route?

Two helicopter RNAV routes (TK-routes) exist in the northeast corridor between the Washington, DC, and New York City metropolitan areas. The TK-routes are for use by helicopters having IFR-approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment.


The regulations define weather flight conditions for visual flight rules (VFR) and instrument flight rules (IFR) in terms of specific values for ceiling and visibility. IFR means a ceiling less than 1,000 feet AGL and/or visibility less than three miles. Marginal VFR (MVFR) is a sub- category of VFR.

What are AR routes?

AR routes allow you the possibility to ride on roads from all over the world, coming together on a real road virtually by generating and processing animated 3D riders in real 2D videos. AR routes are recognizable when you see your avatar.

What is a jet route?

A high-altitude route system for aircraft with high-altitude navigational aids that normally extends from 18,000 ft AMSL (above mean sea level) to flight level 450. Flights using jet routes will report over these points unless other-wise advised by ATC (air traffic control). Also referred to as high-level airways.

What is rnav1?

Area Navigation (RNAV). For the purposes of this AC, the specified RNAV accuracy must be met 95% of the flight time. (1) RNAV 1 requires a total system error of not more than 1 NM for 95% of the total flight time. (2) RNAV 2 requires a total system error of not more than 2 NM for 95% of the total flight time.

What does RNAV 5 mean?

B-RNAV/RNAV 5 is defined as RNAV that meets a track keeping accuracy equal to or better than +/-5 nautical mile (NM) for 95 percent of the flight time. This value includes signal source error, airborne receiver error, display system error, and flight technical error.

Can private pilots fly in MVFR?

Yes, private pilots are authorized to fly MVFR, though should probably avoid doing so until they have plenty of experience flying in MVFR conditions with an instructor.

Can VFR pilots fly above clouds?

“The short answer is yes. You may legally fly on top as long as you can maintain the appropriate VFR cloud clearances. The only regulatory restriction is that student pilots are not allowed to fly above a cloud layer without ground reference.

What days do YCAT routes run?

What is the project routes list?

This list includes those routes which are numbered sequentially in a region as well as those which do not have numbers, but names instead, and help to link between numbered routes. This article is part of Project Routes, a Bulbapedia project that aims to write comprehensive articles on every route in the Pokémon world .

Why establish Q and T routes?
