We are doing projects with both and the consequences are quite different. In my view Ravenscar only reduces the risk of rogue tasks. Take as an example 00-55 version 2, SIL 4; then one must provide an audit trail of the software production process. As you are using a COTS OS I should point out our experiences with Wind Rivers Systems. You will hit a dead end or go down the NON COTS path, and even then I am not sure you will succeed. We had to switch to another OS. I suggest you look at the alternatives; which do exist if you were to use Ada95 and PowerPCs. If you want the full background of my investigations, I suggest you privately e-mail me on ian.kerr@baesystems.com as you are covered by some NDAs. That applies to anyone else who would be interested, minus details of OS divulged by WRS and Enea OSE. Candidate 3 did not require an NDA. You can come to your own conclusions.
