Boeing and Airbus both use Ada for their commercial airliners' avionics SW. Raytheon uses Ada for air traffic control SW. SPARC is a processor; I presume you mean SPARK. As for arms, they're going to exist whether you work on them or not, and they're going to be controlled by SW. So the important thing, it seems to me, is how reliable that SW is. Do you want to be involved in ensuring the safety of yourself and those you care about, or are you willing to leave that to someone else? > So, is it true that for the things Ravenscar are used for, there are no > good alternatives? Concurrency in Java is quite low level and error prone, including the RTSJ. Ada is much better, and Ravenscar better still, but for the most critical RT SW, you might want to look at RavenSPARK. Unfortunately, the lack of good alternatives rarely stops people from using poor alternatives. -- Jeff Carter "Sons of a silly person." Monty Python & the Holy Grail 02
