What is the altitude range for T routes in RNAV?

• A. Surface to 1200 AGL
• B. 1200 AGL to 18000 MSL
• C. FL180 to FL450
• D. FL450 and above

Answer: (B)

The altitude range for T routes in RNAV (Area Navigation) is from 1200 AGL (Above Ground Level) to 18,000 MSL (Mean Sea Level). T routes are specifically designed for use by en route aircraft operating under Instrument Flight Rules (IFR) in controlled airspace. They facilitate the use of RNAV systems, allowing for more efficient routing and improved airspace utilization. This specific altitude range allows for the integration of T routes into the existing airspace structure. Below 1200 AGL, routes are generally not classified as IFR or managed by the RNAV system, which is why the lower limit starts at 1200 AGL. The upper limit of 18,000 MSL signifies the transition from the lower altitudes, where general aviation and other aircraft operate, to the higher altitudes of the jet routes and airways above. This range ensures that T routes can effectively manage air traffic without conflicting with established air traffic routes and altitudes for commercial and general aviation.
