LOA/ZWY ZDC

Letter of Agreement

New York Oceanic (ZWY) & Washington ARTCC (ZDC)

Rev. 2 - 11 Jan 2016

Purpose: This agreement prescribes transfer of control procedures, radar handoff procedures, route/altitude assignments, and delegation of airspace between New York Oceanic (ZWY) and Washington ARTCC (ZDC).

Scope: The procedures contained herein must apply unless prior coordination is effected.

Disclosure: vZNY and any other facilities mentioned in this document are affiliated with the Virtual Air Traffic Simulation (VATSIM) network. The procedures outlined in this document are intended exclusively for use in the VATSIM flight simulation environment and must never be used for actual flight or air traffic control operations. vZNY and any other facility mentioned in this document are not affiliated with the FAA in any manner.

ZWY hereafter refers to New York Oceanic.
A transition fix is a fix inside or at the edge of ZDC airspace that is the last fix in the aircraft route prior to its entry into ZWY airspace, or the first fix in the aircraft route upon its entry into ZDC airspace.

ZDC shall provide oceanic clearance to the traffic by obtaining the estimated time, speed, and altitude for the transition fix from the pilot and relaying that information to the ZWY controller.
- Traffic entering ZWY does not need to contact NY Radar for an oceanic clearance.
Traffic entering ZWY airspace must be separated by at least 30 nm from all neighboring ARTCCs and from all other traffic that is entering ZWY airspace through ZDC airspace.
Traffic entering ZWY airspace through the same transition fix must be separated vertically or using time separation.
- For traffic passing the same transition fix at the same altitude and the same speed, 10 minutes of separation shall be created prior to handoff. If the trailing aircraft is flying at a faster speed, for each 0.01 Mach difference in speed, ONE minute should be added to the separation.
All handoffs must be initiated no less than 10 nm from the sector border.

ZNY Sectors 82 and 83 (depicted in Attachment 1), including those parts of Warning Areas W-72A, W-72B, W-110, and W-122 that are within the confines of ZNY sector 82 and 83, are delegated to ZDC. If ZDC is offline, New York Oceanic (ZWY) can provide radar services in these areas for traffic whose filed route transits through ZWY airspace.
ZNY Sector 86 (depicted in Attachment 1), including those parts of Warning Areas W-107, W-386, and W-387 that are within the confines of sector 86, are controlled by ZNY. If ZNY is not online, ZWY can provide radar services in these areas. ZDC has no authority in those parts of the aforementioned Warning Areas which are inside the lateral boundaries of ZNY Area 86. ZNY has no authority in those parts of the aforementioned Warning Areas which are outside the lateral boundaries of ZNY Area 86.
