The glide path angle at London City 5.5, and Seon in Switzerland, don’t remember the angle but steep, with sheer cliffs to the port side and an offset step to the right at the bottom, do stick out as being memorable. but the glide slop indicator seemed perfectly logical.This was puzzling.
The approach symbology for the F-35 on first exposure reminded me of a comment made by an ‘older’ pilot first exposed to ‘glass cockpit’. When asked by his sim instructor how he had found the experience, his comment was, “now I know how my dog feels when we are watching PM’s questions time on the TV.”
As an afterthought, the glide angle on an engine out in a Bensen Autogyro is around 45 degrees.
