The flight crew will then disengage IAN by disengaging the autopilot and autothrottle and fly the remainder of the approach manually as per NPA protocols. Rather, IAN has been designed to guide the aircraft to the MAP published on the approach chart. Therefore, NPA procedures must be adhered to when initiating an approach using IAN.Īlthough the automation provided by IAN will guide an aircraft (in most cases) to the threshold of the runway, IAN has not been designed to do this. Although, the glide path may not comply with altitude constraints in the FMC prior to the FAF, the generated glide path will always be at or above the altitude constraints between the FAF and the Missed Approach Point (MAP) displayed in the FMC.Ĭritically, an IAN approach is a Category I Non Precision Approach (NPA) and is not to be confused with an ILS Precision Approach. IAN is an airline option, and although not every airline carrier will have IAN as part of their avionics suite, the technology is becoming more popular as the safety and economic benefits of IAN are understood by airline carriers.Īn IAN Approach approximates a 3 degree glide path (descent profile) from the Final Approach Fix (FAF) to approximately 50 feet above the runway threshold.

The approach must include a series of waypoints that depict a vertical profile that includes a glide path.Īn IAN approach may be flown with a single autopilot, raw data, or by following the visual cues displayed on the Flight Director (FD). To use IAN, an approach with a glide path must be selected from the FMC database. Flight path guidance is derived from the FMC, navigational radios, or combination of both. In so doing, it displays visual cues similar to the Instrument Landing System (ILS). Integrated Approach Navigation (IAN) derives information from an approach type selected from the Flight Management Computer (FMC) database to generate a 3 degree glide path from the Final Approach Fix to the threshold of the runway.

The Boeing Flight Crew Training Manual (FCTM) has an excellent section addressing IAN, and I recommend you read it to gain a greater understanding of how the IAN system functions. In this article, I will discuss the concept of Integrated Approach Navigation (IAN) and explain the procedures recommended by Boeing to successfully implement IAN. Not to mention, the benefits that a stabilized and safer approach bring: greater passenger comfort, less engine wear and tear, and lower fuel usage while bringing less workload for the flight crew. This improves landing capability in adverse weather conditions, in areas of difficult terrain, and on existing difficult to fly approach paths. LEFT: Japanese airlines nearly always gravitate to new technology. These augmented approach types provide a constant rate of descent, follow an approximate 3 degree glide path, and eliminate the traditional step-down style of approach. Increased navigational accuracy obtained from software and hardware improvements have led to several enhanced approach types being developed for the Boeing 737.
