Aircraft Inventory Definitions Quiz

Aircraft Inventory Definitions

• TAI (Total Active Inventory): Aircraft assigned to operating forces for mission, training, test, or maintenance functions. This includes PAI + BAI + AR.
• PAI (Primary Aerospace Vehicle Inventory): Aircraft assigned to meet the Primary Aircraft Authorization. This is made up of PMAI + PTAI + PDAI + POAI.
• PMAI (Primary Mission Aerospace Vehicle Inventory): Aircraft assigned to a unit for performance of its wartime mission.
• PTAI (Primary Training Aerospace Vehicle Inventory): Aircraft required primarily for technical and specialized training for crew personnel or leading to aircrew qualification.
• PDAI (Primary Development/Test Aerospace Vehicle Inventory): Aircraft assigned primarily for testing of the aircraft or its components for purposes of research, development, test and evaluation, operational test and evaluation, or support for testing programs.
• POAI (Primary Other Aerospace Vehicle Inventory): Aircraft required for special missions not elsewhere classified.
• BAI (Backup Aerospace Vehicle Inventory): Aircraft above the primary mission inventory to permit scheduled and unscheduled depot level maintenance, modifications, inspections and repair and certain other mitigating circumstances without reduction of aircraft available for the assigned mission.
• AR (Attrition Reserve): Aircraft procured for the specific purpose of replacing the anticipated losses of aircraft because of peacetime and/or wartime attrition. AR is calculated from across an entire Weapons System, MDS, and not based on an individual unit.

Committable Aircraft Guidelines

• Management Difficulty: CANN managers may experience more difficulty managing and maintaining aircraft forms and MIS requirements, as units will accomplish document reviews and QA assessments more frequently.
• Extended Downtime: Aircraft remaining down for extended periods may require additional Dash 6 inspections (e.g., mandatory 30-/90-day no-fly calendar inspections, OCFs, FCFs).
• Bomber Units: No more than 40 percent of PAI should be committed to the flying schedule.
• Legacy Fighter/CSAR & MQ Units: No more than 65 percent of PAI should be committed to the flying schedule (e.g., A-10, F-15C/E, F-16, HH-60, MQ-1/MQ-9).
• Fifth-Generation Fighter Units: No more than 55 percent of PAI should be committed to the flying schedule (e.g., F-22, F-35).

War Readiness Engine (WRE) Levels

• Definition: The quantity of net serviceable engines required to support the Air Force war tasking and to sustain operational units’ war efforts until pipelines are filled and repair capabilities are available. These engines are to be available to support a weapon system from the start of the war until re-supply (via base, intermediate, CRF, or depot repair) is established.
