total technical life (TTL)

[qassure]

Howmany MTBFs can be in Total Technical Life (TTL)of a component. In other words from the given MTBF is it possible to calculate TTL. Please tell me how. Also how to select a component to meet the design life of a electronics system and how to prove it.

Given that many discussion of TTL involve life extension, the answer would appear to be No.

This is borne out by the fact that 30-yr old AH-1 Cobras are still flying, even though their MTBF is less than 100 hrs of flight time.
