Gentleman and ladies. I am in the throws of studying for an upcoming interview. I came across these two questions or similar ones which appear on the written test. I want to make sure I have the concept/answers correct, any help, input, websites would be greatly appreciated.
1. XYZ field elevation = 34' OAT = 36C QNH = 1002 What is the density height?
PH= elevation + (1013- QNH) x30 34+(1013-1002) x 30= -296
DH= (temp-ISA) x 120+ PH 36-15 = 21x120= 2520 - 296= 2224'
DH = 2224
2. at high noon in Sydney (150 degrees E long) the sun is at its highest point. What time is it in Sydney when the sun is at its highest point in London.
I came up with 2200. Long= 4mins 150x4=600mins (10hrs)
