hi buddies, yesterday I rode for the very first time on a Saab 340 and I have got to admit that I was impressed by the handling characteristics of that aircraft, besides I had the chance to peer into the cockpit and I noticed that it is equipped with a state of the art avionic suite, is there any body out there that knows any site where I can get some detailed technical informations and cocpit pictures of the Saab, if you could indicate me any flight guide on line that would be great!!!!
THANKS AND REEVALUATE THOSE TURBOPROPS

Believe it or not, EFIS isn't always the "state of the art".

The avionics system in the SAAB 340 is close to 20 years old.

The Collins EFIS 86 is an older anolog system that doesn't use a databus to interface to the navigation radios. It is also quite difficult to interface with new systems such as FMS/GPS and TAWS.

In spite of that, the system performs quite well and I agree that it's an impressive airplane.

Like Airplay said, the Collins Pro Line II avionics in the Saab 340 are really quite "old school" by todays standards.

I remember working on them quite well. The autopilot would log faults in voliatile memory, meaning when power was removed from the aircraft, any logged faults were erased. Nothing like getting an autopilot gripe and bringing up the diagnostic page to find no faults recorded. And, of course, any intermittant problems were nearly impossible to track, since it always worked fine on the ground. Bad servo? Difficult to pinpoint until it suffered a hard failure.

Not to mention the AHC-85 attitude heading computers. A bastardized inbred between the older analog gyros and then newer laser ring gyros. Compass swings were always a two to three hour ordeal. I'm convinced the designers were either retarded or drunk when they came up with that design. Spinning drums with piezio electric tabs on them?!? What were they thinking? It was incredibly fragile. Set one in the back of your truck and allow it to fall over, and thet's all she wrote. Back to the shop for some $20,000 in repairs. I remember the box they came in--it was about five times bigger than the actual size of the computer, with specially cut foam packing.

The Pro Line II system is used on the EMB-120 as well as several other aircraft.
