The second segment of Net Take Off Flight Path requires a net gradient of 2.4% and there is a 0.8% safety margin to add to get the gross gradient. 2.4% equals to 144 fpm/nm but I am unsure on how to calculate the gross gradient.
If I add 8% to 144 fpm I get 155 fpm. If I add 0.8 to 2.4% I get 192 fpm/nm. (3.2x60=192).
I know the numbers but I have never had to make any calculation during my groundschool period nor exams and now I would like to get this lack of 'knowledge' fixed
