7. JAST

What is the effect of engine number on attributes of a Joint Service Fighter A/C

1. Multi-Service Operation

2. Affordability

3. Survivability

4. Readinesss

5. Mission Capablitiy

6. Operational Safety

What is the new approach for Weapon System Effectivenss

Evaluation is now based on overall evaluation criterion approach with user specified relative importance weights

What must the Overall Evaluation Criterion capture and what is the equation for it?

It must capture all aspects that define the merit of a single vs twin engine configuration

How will the aspects of the OEC now be accounted for

What is Life Cycle Cost and write its equation and units

Used to evaluate affordability in units of ($/Flt hrs)

What is Mission Capability Index and write its equation and units

Used to evaluate capability of an aircraft

What is the Engine Caused Attrition Index (EIC)

Measure of the loss of an A/C which translates to reduced capability and possible loss of life

What is Operation Readiness and what is the equation for the ORI

The capability of a unit, ship, weapon, system or equipment to perfrom the missions or functions for which it is organized or designed

What are the Operational Availability Equations needed to solve for ORI

What is the equation for inherent availability

What is survivability and write the equation for it

It is a measure of an A/C’s ability to evade detection and avoid damage which would result in loss of vehicle

Summary of Equations for the Evaluation Criteria

What is the importance of Operational Safety

Must be kept objective so that data isn’t skewed towards one’s personal views
