Two types of dependencies may be identified:
.
Necessary overlap and interface between other associated projects: e.g. an En Route airspace project and a Terminal Airspace design team project can only be successful if there is a ‘sharing’ of team members.
.
Scheduling dependencies: for example, the PANS-OPS office cannot design the SIDs and STARs in accordance with obstacle clearance criteria until the SIDS/STAR concept has been developed and the SIDs/STARs have been validated in a holistic ATM context.
2.4.3.2 Task Scheduling and Implementation
It is extremely important that the Terminal Airspace design team ensures that planningallows all identified tasks and activities to be completed before implementation.
.
In those cases where Terminal Airspace design team works within the framework of an ATM Project, the team may be in a position to decide its own implementation time-scales. In this case, care should be taken not to under-estimate the time needed to complete the tasks and to add in extra days (approx. 10%) to allow for error or unforeseen difficulties.
.
Where a Terminal Airspace design project is undertaken within the framework of a Major infrastructure project or initiated by External Directive, the Terminal Airspace design team is required to meet a pre-determined time-scale, chosen by someone else. (In the case of an external directive project, time scales could be very short). In this case, the Terminal Airspace design team should ensure that the work is organised so that the tasks can be completed in the time available. Where timescales are extremely short, this would usually result in more human resources being required to accomplish the tasks.
A sample task list is provided as an attachment to this chapter.

This Chapter has discussed the planning steps applicable to a Terminal Airspace design project in the context three managerial framework Types. It has shown that planning the work and doing the work are critical elements to be accounted for when selecting a date for implementation or when working towards an implementation date.
This Chapter contains three Attachments, one shows a Sample Planning schedule, the second a sample task list for a Terminal Airspace Design project, the third a summary of the Planning Process discussed in this and the previous chapter.
