Final answer:
To calculate the minimum rate of descent needed during final approach for the NDB-C at Marianna Muni, FL (MAI), use the formula: Minimum Rate of Descent = (Ground Speed)^2 / (2 x Distance)
Step-by-step explanation:
To calculate the minimum rate of descent needed during final approach for the NDB-C at Marianna Muni, FL (MAI), we need to consider the physics of motion and acceleration. The minimum rate of descent can be determined by calculating the vertical acceleration required to maintain the desired ground speed. At 90 Kts ground speed, the minimum rate of descent can be calculated using the formula:
Minimum Rate of Descent = Vertical Acceleration = (Ground Speed)^2 / (2 x Distance)
Since the distance is not provided in the question, we cannot calculate the exact minimum rate of descent without that information. However, the general formula gives us the relationship between the ground speed, distance, and minimum rate of descent.
