Technical Decision Questions On Programming The Fms And...

The first decision discussed in programming the FMS and ACARS will be choosing the correct runway to request data for. Choosing the runway is an analytical decision, as information needs to be analyzed correctly. An airport’s ATIS will list the active runways in use for departures. If multiple runways are being used for departure, pilots will need to anticipate the runway they will use. Pilot will use their location relative to the runways, direction of departure, and previous experience to decide on a runway. Pilot’s previous experience can be heuristic as certain airport conditions lead to specific runway operations. It is sometimes referred to as â€Å"tribal knowledge† when anticipating the correct runway. Sometimes airports will use a†¦show more content†¦There can also be a runway change after the initial assignment, which leads to the task starting all over. Time is the biggest stressor in this decision. A pilot always wants to anticipate the corr ect runway so that it will reduce their workload during taxing. If they picked the wrong runway they then have a lot of work starting the request task over in a short period of time. The second decision looked at will be deciding if the received data is correct and valid to accept and use. This decision can be either intuitive analytical. Analytical is the correct way to make the decision however. The decision is analytical because pilots are supposed to verify all the information that was used to compute the takeoff data such as wind, altimeter, flap setting, and runway. That takes additional time but is the correct method. Most pilots make the decision using intuitive decisions making. Pilots receive preliminary takeoff data during their preflight. If the v speeds on the final takeoff data received is within a knot or two of the preliminary takeoff data v speeds pilots will use that as their check. They can accomplish that much quicker and use it as a shortcut. If any of the information isn’t correct for the situation it is important pilots catch it or it can lead to invalid data being used. Time is the biggest pressure in this decision. This decision is generally made while taxing which is a high
