The airway structure in placesother than North America vary by location, etc. and are not discussed in this book. Low Altitude Airways(Victor Airways or T-Routes) start 1,200 feet above ground level (AGL) and extend up to 18,000 feet mean sealevel (MSL). Low Altitude Airways are designated with a “V” or a “T” before the airway number.High Altitude Airways (Jet Routes or Q-Routes) start at 18,000 feet MSL and extend upward to 45,000 feetMSL. High Altitude Airways are designated with a “J” or a “Q” before the airway number.Low Altitude Airways are drawn in gray (the same shade used for roads). High Altitude Airways are drawnin green. When both types of airways are displayed, High Altitude Airways are drawn on top of Low AltitudeAirways.When airways are selected for display on the map, the airway waypoints (VORs, NDBs and Intersections) arealso displayed.Figure 5-15 Airways on MFD Navigation PageLow AltitudeAirway(Victor Airway)High AltitudeAirway(Jet Route)Low AltitudeAirway(T-Route) High AltitudeAirway(Q-Route)Airways may be displayed on the map at the pilot’s discretion using either a combination of AWY Softkeyselections, or menu selections using the MENU Key from the Navigation Map Page.
