AoA and ASI low speed awareness
Hello,
I'm having a senior moment, and would appreciate some clarification. On a modern jet, how is AoA information translated to IAS indications on the speed tape?
Let's say you think you weigh 100T, but your actual weight is 110T. You'll notice on final that your computed approach speed is awfully close to the top of the low speed awareness tape on the PFD.
This indicates the system is calculating a stall speed higher than the one you've calculated. How does it realize that you don't weigh 100T, and that it needs to show speeds for 110T?
