This article looks at cockpit upgrades, aircraft retrofits, and flight management systems (FMS) as they relate to the airplane and the avionics industry. Advantages such as reliability gains, fuel savings and emerging airspace benefits need to be weighed against costly aircraft alterations such as winglets that are designed to reduce aircraft drag. The article relates Southwest's $750,000-a-piece retrofit of Blended Winglets on 170 of its 737-700s, and the associated fuel savings and payload boosts that will offset the retrofit costs. The Required Navigation Performance (RNP) procedure, although still in its infancy, is expected to become the preferred method of navigation in the next decade. While the RNP requires an upgraded FMS and GPS system, and has set limits for navigation errors, it leads to compacted routes, meaning that operators can achieve significant time savings on long-duration oceanic flights by taking advantage of ideal wind conditions. The article also looks at the growth in liquid crystal display (LCD) technology, and while it offers significant advantages for flight instrumentation panels, airlines have been slow in following through with orders.
