Runway 06 has a different
decision height, Ramo added.
* We arrive at the published MAP or
decision height and visual reference to the runway environment is insufficient;
Approaching the
decision height, I noticed we were rapidly decelerating and instructed my co-pilot to gain airspeed.
The European Aviation Safety Agency evaluates the possibility of making it mandatory that flight crews are trained in go-around manoeuvres, even from below the
decision height;
Developed with US Federal Aviation Administration participation, AMS describes the Model 2100 architecture as having been approved for Category I (60 m
decision height, 800 m runway visual range), II (30 m
decision height, 400 m runway visual range) and III (200 to 50 m runway visual range) operation and as being available in multiple configurations featuring a wide variety of antenna arrays.
The transition took place at about 200 ft (61.5 m) above ground level (agl), which was also the
decision height the pilots were given.
When we talk about Category I ILS, we mean your normal garden-variety ILS approach with a
decision height as low as 200 feet and visibility requirement as low as one-half statute mile (1800 RVR in some cases).
The recent upgrade now enables aircraft equipped for CAT II equipment and crewed by similarly qualified pilots to land in poor visibility conditions down to a runway visual range of 350m with a
decision height of 110ft.
Pilots must not correct altitudes published on Standard Instrument Departures (SIDs), Obstacle Departure Procedures (ODPs) and Standard Terminal Arrivals (STARs) but they must use the corrected Minimum Descent Altitude (MDA) or Decision Altitude/
Decision Height (DA) as the minimum for an approach.
For example, on a typical precision instrument approach with a 3 degree glideslope and published
decision height (DH) of 200 feet, a 50-foot error in the pilot's altitude indication raises the ceiling requirement to successfully conduct the approach by 25 percent, and the visibility requirement by nearly 40 percent.
The regulations that the pilots allegedly violated included those relating to "operations below
decision height or minimum descent altitude, emergency evacuation demonstration and cockpit checklist procedure."
