Low Visibility Ops - sitting too low in flight deck calculaiton
Hello smart ppruners.
Looking to calculate the theoretical the of visibility if a pilot sits 1 cm too low in flight deck on an ILS approach.
ie If in the correct position at the minima of a CAT I ILS a pilot can see exactly 800m, using an average cutoff angle, roughly how much less would forward visibility would they see if they seated 1cm too low?
Please help if suitable. Any diagrams would also be most appreciated.
