How to calculate Pitch in limits , or VS

[rwsd_1]

Hi guys as you can see I’m creating some mission for the Mosquito and Spitfire. 
 

so far I’ve created over 200 triggers so far for this specific mission based in the spitfire. 
 

however I cannot get a trigger to work when banking down on the target in a dog fight 

can anyone help with pitch in limits and explain how one can calculate it when the aircraft is in a dive ?
