Slip indicators
Hi all. I've just got a quick question regarding slip indicators on modern aircraft, say the A320 or 737-NG for example. How is the slip indication generated? I'm quite sure it comes from the ADC/IRS but how is it generated in these units? What I'm getting at is, are beta probes used in the same way there are alpha probes (as seen on some fighters?).
