THE PROBLEM: Thefollowingquestionsillustratesomechallengesindesigninganddevelopingsafetycriticalavionics.
Which tasks are assigned to me?
How can I become fa-miliar with the relevant
standards?
Which standards do I have to consider?
How do I ensure the quality of the
documents?
How can I easily produce the required documents?
How do I avoid costly process errors?
How can I ensure to keep my project on
time?
Which processes do I need to follow?
Which documents do I have to create?
Which parts of the standards are relevant to me?
What do I do if there is more than one standard?
How do I apply a standard appropriately?
Which documents are mandatory for certification?
Do I have to issue documents formatted in a specific way?
How do I avoid preparing unnecessary documentation?
How do I know that there is a new standard?
What do I have to take into consideration if there is a
new standard?
