A remote pilot sees a route labeled 'VR1452' on a sectional chart crossing the planned operations area. Based on the designation, what can the pilot determine about the altitude of traffic on this route?
Why →
Per AIM 3-5-2, Military Training Routes are designated by the number of characters following the route type prefix. A four-character designation (such as VR1452) means all segments of the route are flown at or below 1,500 feet AGL. A three-character designation means the route has at least one segment above 1,500 feet AGL. VR1452 being four characters means military aircraft on this route may be at altitudes that directly overlap with sUAS operations.The trap →
More characters might seem to imply higher airspace, but the opposite is true. Four characters means entirely low altitude. Three characters means at least one segment goes higher, and other segments may still be low.SOURCE → AIM 3-5-2CHECKED APR 22ACS II.A.K2MED
