This is going to seem like a really stupid question, but my experience is limited to jets that are 100% pure glass so I'm kind of curious. On the 757/767s with the older needle style airspeed indicators, what is there for low speed indications/low speed awareness? I'm used to the Embraer/320 where it can be kind of a moving target depending on flap setting/speedbrakes/or even turbulence where the low speed cue will shoot up and down depending on those things, but what kind of indication would you have without that? Speed cards and manually looking at the minimum maneuver speeds? What about the aforementioned instances here instantaneous load factors in turbulence or with the boards out are likely to cause variations in that?
