Refer to figure or CAP758 Figure 3.14.
Given the following information, determine the All Engines Operating fuel flow per hour for the TETH:
Pressure altitude: 5 000 ft
OAT: 0°C
Mass: 17 000 lb
Refer to figure.
1. The figure 3.14 at the top left corner refers to ISA, thus the density altitude must be determined:
- The ISA temperature at 5 000 ft is: +15°C - (2°C x 5 000ft/1000) = +5°C.
- Thus, the ISA deviation is: OAT - ISA temp. at 5 000 ft = 0°C - 5°C = -5°C.
- The density altitude is: Pressure altitude + (120 ft x ISA deviation) = 5 000 ft - (120 x 5) ft = 4 400 ft.
- Enter with the density altitude 4 400 ft and move horizontally to the right until crossing the 17 000 lb mass dotted line.
- Continue vertically down and read the hourly fuel consumption: 452 kg/hr, 562 l/hr, 995 lb/hr, 149 USG/hr.
