What is the ideal range of disk loading for high hover performance?(a)

1.	What is the ideal range of disk loading for high hover performance?(a) 10-100 \(\frac {N}{m^2}\)(b) 100-500 \(\frac {N}{m^2}\)(c) 1000-4000 \(\frac {N}{m^2}\)(d) 5000-10,000 \(\frac {N}{m^2}\)This question was addressed to me at a job interview.This interesting question is from Momentum Theory topic in section Helicopter Dynamics of Aerodynamics
Answer» The correct answer is (b) 100-500 \(\frac {N}{m^2}\) For explanation I would say: BASED on the MOMENTUM THEOREM for the hovering helicopter, the disk loading must be of the minimum VALUE to have a low value of power to thrust. Disk loading value generally ranges between 100-500 \(\frac {N}{m^2}\) for the best PERFORMANCE.
