Aerodynamics ? RJ ?
I am looking for a deeper aerodynamical answer, why some airplanes do and others donīt such as the 727 ? It came up again with the RJ since the RJ also doesnīt have Ice Protection on the Horizontal Stabilizer
What about the sweepback on the wings ?
In flight testing they obviously found that they did not pick ice. It is interesting to note that some other jets do have Ice Protection on the horizontal stabilizer.
Thanks for the input as I had an answer but I was not happy with it.
