What is the purpose of conducting a weight and balance calculation?

The primary purpose of conducting a weight and balance calculation is to ensure the helicopter operates within its weight and balance limits. Every aircraft, including helicopters, has specific limits for weight distribution and center of gravity (CG) placement. Adhering to these limits is crucial for maintaining stability, control, and overall safety during flight.

When the helicopter is loaded within its weight and balance limits, it ensures that the helicopter can perform as expected, with adequate control authority and predictable handling characteristics. An aircraft that is either overweight or has a CG that is too far forward or aft can experience degraded performance, increased stall risk, and difficulty in maneuvering.

While optimizing fuel efficiency, maximizing performance range, and maintaining fly-by-wire functionality are important considerations for overall aircraft operation, they fall secondary to the fundamental need to stay within safe operational parameters dictated by weight and balance calculations. Without proper weight and balance, performance in these areas could be compromised, potentially leading to unsafe flight conditions.
