Final answer:
To calculate the True Airspeed (TAS) for a standard rate 1 turn at 18 degrees angle of bank (AOB), the correct option would be (X * 5%) + 12 = 18 —> X = 120 KTS.
Step-by-step explanation:
To calculate the True Airspeed (TAS) for a standard rate 1 turn at 18 degrees angle of bank (AOB), we can use the given options and equations provided. Let's analyze each option:
A) (X * 10%) + 7 = 18 —> X = 110 KTS
B) (X * 15%) + 5 = 18 —> X = 120 KTS
C) (X * 5%) + 12 = 18 —> X = 120 KTS
D) (X * 12%) + 6 = 18 —> X = 100 KTS
Based on the calculations, the correct answer would be Option C) (X * 5%) + 12 = 18 —> X = 120 KTS.
