Question 2
A take-off path contains two significant obstacles as follows:
Obstacle one
Distance from zero reference: 780m
Height above zero reference: 96ft
Obstacle two
Distance from zero reference: 1210m
Height above zero reference: 128ft

Given the following data what is the minimum gradient required to clear both obstacles:
  • Aerodrome PA: 11ft
  • OAT: +25C
  • ACS packs: off
  • Slope: nil
  • HWC: 10kts
  • FLL TOW: 202,500kg
a)4.7% b)4.2% c)4.4% d)4%

What I did: Using (UK-CAP385)(Fig18) false temperature 29C, I get 3.25%. I am trying to solve using Fig29 to get the answer. I am stuck...
