Istanbul Airport: Difference between revisions

As mentioned previously, Istanbul Airport utilizes Point-Merge System. Each PMS leads to last point of the STAR and '''the entry point of the approach transition'''. For northern config, IAF for west PMS is ''IMREN'', for east config it is ''SADIK''. For south config, IAF for west PMS is ''INSTA'' and for east PMS it is ''DIVDI''. '''Flying the correct transition is crucial and must'''. Each pilot is responsible for selecting the correct transition. This transition is '''NOT a STAR''' transition but transition for the approach procedure. There are different approach procedures and each has different transition phase (both laterally and vertically), go around procedure and used differently to streamline the independent parallel approach procedure . As a pilot, you must make sure you have programmed your FMS using the correct approach procedure and transition. '''Each pilot is responsible for selecting and flying the correct transition whether ATC is online or not.''' Since transitions are a must as they play a crucial role in the independent parallel approach procedure, pilot's must fly the transition both laterally and vertically at all times. If the transition is not selected correctly in the aircraft's FMS, the plane will fly directly to FAF, skipping the transition completely. This is not allowed for approach procedure into Istanbul as each approach procedure and transition is very different than one another, both laterally and vertically. You can see an example of how ILS-X and ILS-Z transition differs from the pictures (you can see they are both laterally and vertically different).[[File:ILS-Z 35R TRANSITION2.png|thumb|ILS-Z Approach (showing both IMREN and SADIK transition)|335x335px]]
