MART Vol. II MO/MP - NESA - Civil Air Patrol

Figure 8-3Warning Areas are similar to restricted areas, except that they are beyond thethree-mile limit from the U.S. coastline and are therefore in international airspace.Alert Areas show airspace within which there may be a lot of pilot training orunusual aerial activity.Hours of use and vertical limits of special use airspace areas, as well as theFAA facility controlling each area, are printed in one of the margins of thesectional chart. If the CAP crew has any doubt about entering special useairspace, it should contact the appropriate air traffic control facility first to checkthe status of the area in question.5.4.2 Military Training RoutesAlthough not classified by the FAA as special use airspace, military trainingroutes (MTRs) are for military low-altitude high-speed training. An understandingof each type of training route, and the manner in which an active route can affectother traffic, will help the CAP aircrew accomplish their intended mission.Military training routes that may be used by high-speed jet aircraft areidentified by one of two designations, depending upon the flight rules under whichthe military operates when working within that airspace. Instrument Routes (IR)and Visual Routes (VR) are identified on sectional aeronautical charts by mediumweightsolid gray lines with an alphanumeric designation. 4-digit numbers identifyMTRs flown at or below 1500 feet AGL; 3-digit numbers identify those flownabove 1500 feet AGL. In Figure 8-4 there are two such examples east of theClarksville Airport symbol -- IR-120, and VR-1102.73
