The STARs at Istanbul airport are designed to be ambiguous between the active runways. For instance, if northern config is active, RILEX2A STAR will end at '''IMREN''' waypoint, and '''IMREN''' is ''IAF'' (Initial Approach Fix) for all approach procedures for all northern runways. This means, whether you land at 34L, 35R or 36 (when north config is active), you still use the same STAR procedure for all runways. You can find the STAR designator table on the next page. | The STARs at Istanbul airport are designed to be ambiguous between the active runways.

<references /> | As Istanbul Airport utilizes multiple configurations depending on traffic, weather, congestion, NOTAMs etc. You might be cleared to a different STAR compared to another traffic that is flying exactly the same route as you. Default designators for northern config (34/35/36) is 2A and default designator for southern configuration (16/17/18) is 2B. These STARs keep the traffic arriving west to use the west PMS and traffic arriving from east to use the east PMS. 2N and 2P STARs are designed to ease the workload of a PMS, by making the traffic to use the opposite PMS (traffic arriving from west to use the east PMS or to enter PMS from north instead of south at different altitude e.g). | ||

=== Transitions and Approach Phase === | |||
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. '''If ATC clears you for ILS-X 35R via IMREN transition, you cannot fly ILS-Y or ILS-Z approach'''. On top of that, you ''have to'' select IMREN transition for ILS-X. If you do not select the transition, 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 below.<references /> | |||
