There were plenty of A variant, line flying, GPS utilizing, regional passenger carrying Saabs in operation, Tim. We've seen them first hand during development of this aircraft.
This was not a "glaring omission", and the current Saab 340 operators using our software to train their pilots would also disagree with you.
If we were talking the B variant I would be more agreeable with you. Considering the fact this product took nearly 4 years to develop, the only glaring omission I'm seeing is your ability to accept you may just be wrong, and that the work put into this product is worthy. The numerous Saab operators seem to think so, anyhow.
