Part 3/7:
Factors Leading to Unstabilized Approaches
The host explains that the key to a successful descent often lies in accurately calculating when to begin the descent. Pilots typically rely on the Flight Management Computer (FMC), which uses several factors—aircraft weight, current speed, anticipated wind conditions—for the most optimal descent calculations.
An example can be illustrated when air traffic control offers shortcuts on the route, often leading pilots to misjudge their descent. If a pilot accepts an unexpected shortcut while their FMC was programmed for a longer route, they might find themselves at an unsafe altitude when approaching the airport, ultimately resulting in an unstabilized approach.
