1- The red zone represents the primary airspace needed for flights to enter and depart the Gaza Strip. Project Unified Assistance (PUA) calls for an aerial corridor which is 20 nautical miles long and 5 nautical miles wide.
2- The green zone represents a secondary airspace needed for executing go-arounds and an aircraft holding area.
3- With the exception of some of the green zone, most of the proposed air traffic control zone is away from Israeli airspace, an important feature to make the proposed airport consistent with Israeli security needs. PUA proposes the aforementioned dimensions based on the 1994 Gaza-Jericho Agreement, which demarcated Gaza’s territorial waters. Though this agreement addressed the zone in terms of fishing rights, PUA wants to use it as a reference point to discuss airspace control for the proposed airport in the Gaza Strip.
4- The proposed airspace and air traffic control assumes the establishment of an airport in a new location on the southwestern coast of Gaza.

A trustworthy air space security system must start with clear parameters on the use of sovereign Palestinian airspace above the future state of Palestine – from surface to 10,000 feet – with limitations on the type of aircraft that would be allowed to fly into and out of Palestinian airports located in the Jordan Valley and Gaza. Those flying in and out* of these airports would recognize that any violation of these limitations could lead to immediate military action by Israel against potentially hostile aircraft.
* All personnel would be thoroughly vetted - air traffic procedures would need to be agreed upon, including emergency situations should Israeli air controllers need to assume authority. And, airports in the new Palestinian state would need to be up-to-date with air traffic control facilities and equipment; as well as security infrastructure and procedures.
A multi-layered maritime security system would be needed. Palestinians would govern their territorial waters off Gaza, but with an external layer of an Israeli security zone, where according to international law Israel is open to intercept, board, and inspect any ship. A Palestinian port could be established in Gaza or via man-made island off of Gaza with special security procedures similar to other border crossings.
