When monitoring helicopter components knowledge of the gross weight an aircraft is operating at is required to differentiate damaging from non-damaging flight conditions. Several attempts have been made at estimating helicopter gross weight using aircraft-mounted instrumentation that have proven inaccurate and costly due to instrumentation and calibration needs. A simple algorithm which requires only engine torgue, hover height, pressure altitude and ambient temperature parameters to estimate gross weight has been developed. The algorithm is based on the UH-IH hover performance chart found in the operators user manual. Results of this effort indicate the algorithm can be used to determine the gross weight range (low, medium, high) while in a hover condition.
