S-Tec System 20/30 Versus System 40/50
A pilot friend insists that there is a fundamental difference in the way
these two systems operate. I am thinking about installing an autpoilot and since I have the extra panel space, I would like to get the System 40 or 50 for (what looks like) a more user-friendly interface. However, he claims that the newer System 20/30 is better at handling its duties in a number of different aspects. Can anyone point me to an article or maybe share their experiences? Google turns up nothing. Thanks, Marco Leon N36616 |

Of course I checked the S-Tec site as well (and I didn't even need Google
for it!). Not surprisingly, the S-Tec literature will not say that one is "better" at certain functions than the other but will only highlight differences. The only two differences that it states are 1) that the System Twenty/Thirty has "Low and high gain" VOR/LOC/GPS tracking and the System 40/50 replaces the variable gain with the ability to track reverse courses and 2) the System 20/30 includes a "roll computer" with its turn coordinator. Can anyone explain why one is better than the other (if at all)? Marco "Schmoe" wrote in message . net...

Both use the same "rate based" technology, very low tech. Which means that
the autopilot cannot tell the difference between roll, skid, and slip. If you have an S-Tec, (or is it Meggitt now?), you need to be careful in turbulence. One should be active on the rudder with this system. What the S-Tec gives up in performance, it gains in safety. Since it depends solely on the electric turn coordinator, a vacuum failure does not affect it's operation. Karl "curator" N185KG "Marco Leon" mmleon(at)yahoo.com wrote in message ...
