Apr 29, 2021 10 Determine weight & balance for Sportsman Category: Weight & Bal
We rented a set of electronic scales, The first step was to level the Sportsman to the waterline with an electronic scale under each wheel. We had previously measured the centerline L to R through the main wheels, the position of the firewall forward of the main wheels and the centerline of the nose wheel. Our datum was the joggle at the front of the fuselage at the intersection with the cowl. From these basic measurements, Stratford, Doug and Brutus jockeyed the Sportsman onto the scales with pieces of wood placed so the plane was level to the waterline which we had marked years earlier during initial construction of our Sportsman 2+2.

Then Doug took the data and used it to create a spreadsheet we can use to insert actually pilot and passenger weights, actual fuel weights and actual baggage weights to keep the CG within the limits specified in our Sportsman Builders Manual being edited by Doug. Of course that data will be used by us for the Foreflight app on our iPhones and iPads.
