author begins by examining two mission areas for which MPA has no equal: maritime surveillance and antisubmarine warfare
(ASW). He then discusses MPA’s capability with respect to integrated task group support and its utility in fulfilling forward
presence objectives. Finally, he concludes with a look at platform capability in terms of OPNAV’s Joint Mission Area
Assessment criteria, which now forms the basis for all future resource decisions.

Many new technological solutions are considered in efforts to improve the efficiency and capacity of the National Airspace
System (NAS). Most of these technologies require the addition or modification of equipment not only on the ground, but also
in the aircraft that operate in the NAS. Because it is increasingly difficult for the Federal Aviation Administration to justify
mandates for forced aircraft equipage, it is often necessary to depend upon the aircraft owner/operators to voluntarily equip
their aircraft with the needed technology. If these aircraft equipage costs are too high, the owner/operators may not equip their
aircraft and the overall program might not proceed as desired. Presented is a methodology that can be used to estimate the user
equipage costs for future air traffic services and capabilities. Included is a forecast of future US aircraft, broken down by model
for Air Transport aircraft and by type for General Aviation aircraft. This forecast, when combined with model or type specific
aircraft knowledge, provides an estimate of the future mix of aircraft capabilities, and can be utilized for any technology under
study. The model considers aircraft classification and architecture to determine equipage states and identifies transition costs
between each state. Also, methods for estimating owner/operator reactions and responses to the availability of the new
technology, as well as the impact and cost of a possible equipage mandate, are presented. An example of usage of the model
is presented that analyzes Automatic Dependent Surveillance - Broadcast (ADS-B) equipage costs for the applications of
broadcast surveillance and cockpit display of traffic information (CDTI) operational procedures. The presented methodology
may also be used for other technological solutions, including navigation and communications.

MITRE Corporation s Center for Advanced Aviation Systems Development (MITRE/CAASD) has developed an
expanded concept for strategic airborne separation that incorporates ground-based conflict detection tools into the original set
of tactical procedures defined as Controller-Assigned Airborne Separation (CAAS). The new strategic tools provide flight
crews with advanced planning information, and air traffic controllers with conflict-free flight plan amendments that include
airborne separation for resolving specific conflicts. To date, CAAS has been studied for potential controller workload reduction
to resolve conflicts between pairs of aircraft only, delegating separation responsibility to the cockpit for limited durations and
under specific operating conditions. The airborne equipment needed for a tactical CAAS maneuver is ADS-B and a modified
CDTI. The expanded strategic concept, which requires data link in addition to ADS-B/CDTI, takes advantage of the
ground-based capabilities to establish strategic conflict resolutions up to 20 minutes in advance, with tools such as User
Requested Evaluation Tool (URET) and Problem Analysis Resolution and Ranking (PARR). Strategic CAAS is the next step
in an ‘airborne delegation of separation authority’ evolution defined by MITRE/CAASD s Future Vision research program.
The goal of Future Vision is to provide a conceptual basis for improvements to the air traffic system that will provide greater
flexibility in flight operations, fewer airborne and ground delays, and a reduction in controller workload, while maintaining
the highest level of safety. Following Strategic CAAS, Future Vision will study grouping of aircraft at high altitude, then
