That's correct. Here is what you had done in your OP.
You further divided 180 hrs by 2 to get
hrs per pilot per aircraft. You got 90
hrs per pilot per aircraft. You then multiplied it by the multiplier 2.5 and declared the product i.e. 225 to be
hrs per aircraft, when it continues be
hrs per pilot per aircraft.
You then multiplied *this* with total number of aircrafts in that segment, and declared it to be total flight hours for 'rotor/fixed transport aircraft'.
Now follow your own formula as you have narrated above. If 180 hrs is hrs per aircraft, then using your logic,
450 hrs (180*2.5) is average flight hrs per aircraft for the 'rotor/winged transport aircraft'. That means total flight hrs for this segment is
293,850 hrs (450*653). That leaves
12,340 hrs for the entire fighter/trainer segment.
Now check my post#78
Since the two types of aircraft log different averages, you have to use 'x' to represent the lowest average and express all other averages in its terms. That's basic algebra. Am sure your Madrassa will teach you algebra sometime in future.
What is 'network54 WAFF'?
EDIT: Oh ok. Got it. WAFF is another forum where you have opened a similar thread.
