Do you want to maximize useful load and minimize flight planning operations? Our weight and balance calculator can be customized with multiple seat and cargo configurations as a simple and cost effective solution.
As you know, airplane Empty Weight and Center of Gravity (CG) change when adding, removing or relocating seats and re-calculating empty weight values is critical to ensure flight safety. eFlite multi-seat configurations automate the process and eliminate time consuming, error prone, number crunching headaches from flight planning.
Multi-configuration users just point and click to automatically adjust Empty Weight and Center of Gravity (CG) values for the selected seat and cargo configuration. Our aircraft weight and balance calculator instantly adjusts for configuration changes so pilot's maintain a precise weight and center of gravity (CG). More Multi-Seat Info
Does your aircraft have a Supplemental Type Certificate (STC) to improve aircraft flight performance? STC's are an eFlite specialty and included in every applicable aircraft weight and balance calculator at no extra charge! We integrate STC data into the aircraft weight and balance calculator so pilot's can utilize every pound of useful load and keep the aircraft center of gravity (CG) within limitations.
