New Mexico flying is defined by altitude before anything else. KABQ (Albuquerque Intl Sunport) sits at 5,355 ft with a 13,793 ft longest runway. KSAF (Santa Fe Rgnl) is higher at 6,349 ft with 8,366 ft available. Even routine departures deserve real takeoff, climb, mixture, weight planning. The state has 65 public-use airports, but only 6 are towered. That creates a sharp contrast between busy controlled fields and quiet CTAF airports. KAEG (Double Eagle II) gives Albuquerque-area pilots a towered, ILS-equipped option with one FBO. Away from the metro areas, most arrivals are self-announce operations with limited services unless the FBO confirms otherwise. IFR access is better than many pilots expect. Twelve New Mexico airports have ILS capability, including non-towered fields such as KLRU (Las Cruces Intl), KGUP (Gallup Muni), KCNM (Cavern City Air Trml), KSRR (Sierra Blanca Rgnl). That helps with alternates, training, positioning flights, but weather and terrain still demand conservative planning. Long runways are common at the top airports. High elevation makes them feel shorter when the temperature rises.
