Final answer:
The approximate altitude lost during the developed phase is 333 FPM (option B).
Step-by-step explanation:
To determine the approximate amount of altitude lost during the developed phase, we need to calculate the difference in atmospheric pressure between two altitudes. We can use the given information to compare the atmospheric pressure at an altitude of 1500 m (5000 ft) and 3000 m (10000 ft). According to the given data, the atmospheric pressure at 1500 m is 8.59 x 104 N/m² and at 3000 m it is 7.00 x 104 N/m².
By subtracting the atmospheric pressure at 3000 m from the pressure at 1500 m, we find the pressure difference to be 1.59 x 104 N/m². This pressure difference corresponds to the altitude difference of 1500 m to 3000 m.
Finally, we can use the relationship between altitude and air density to estimate the altitude lost during the developed phase. Referring to Table A3 (Altitude to Air Density Relationship), we see that for an altitude difference of 1500 m, the air density drops by approximately 333 (FPM) or feet per minute. Therefore, the approximate altitude lost during the developed phase is 333 FPM.
Hence, the answer is option B.
