Q

What’s the primary objective of Comprehensive Engine Management System (CEMS)?

A

Obtain accurate info on the stats, condition, and location of engines, modules, gearbox’s in the AF inventory

21
Q

What is used to collect and store info provided by different engine reporting systems?

A

Comprehensive engine maintenance systems (CEMS)

22
Q

What are the primary objectives if the engine reporting system?

A

Maintaining timely and accurate engine inventories ans well s surveillance of base repair, transportation, overhaul, and historical data in order to forecast funding and replacement requirments

23
Q

What section monitors engine removals and replacements and tracks components at the base level?

A

Base level engine maintenance

24
Q

What are some of the functions of CEMS?

A
  1. Provides for AF readiness through the collection of info. which, when accumulated, idicates the overall view of capability
  2. Answer the question of how many engines and components are available at ny one time
  3. Provides for cost–effective use of available resources, since it allows components and engines to be shifted from places of excess to high-need areas
25
Q

What are the two categories of status reporting?

A

1st. Engines and Modules

2nd. Tracked Components

26
Q

What is the purpose of AFTO IMT 95?

A

Maintaining a permanent history of significant maintenance actions on end items of equipment including, but not limited to, aerospace vehicles, engines, engine modules, and designated -6 TO components

27
Q

What should you do if an automated data system is not available for engine status reporting?
