Notso!!!

A window and a horizon is not enough!!!! Your post beggars belief. How do you think vfr flying is taught. I am sure you are aware of Beagles credentials and if he says it was 40 degrees then it was probably somewhere in the region of 39 -41 degrees! Having flown all manner of light fixed wing, jetstreams, ATR's and now jets for airlines various i can assure you that every ops manual i have read has stipulated that normal turns should not exceed 30 degrees angle of bank. In fact in most airlines if 30 degrees is exceeded the NHP is required to call "bank angle"! Then again maybe you work for Iberia!!
