What is BMI,
Thanks for the tip of A.trammel
I have tried it and it really works.
Basicly you altitude ex. fl 290 correspond to 29 miles on your radar screen. You should tilt radar that ground clutter becomes noticable around 29 miles, then tilt the radar 10 degrees up, which should align the radar beam with the flight path. this works on decend also.
Thanks
