ASW-19 Maximum Weight

What about the weight of the horizontal stabilizer?Â* Given that it produces negative lift and contributes to the bending loads on the main spar, is it considered a lifting part or part of the non lifting components?

Unless I am missing something all you need to know is the particular gliders actual (not assumed manufactured) weight of the non-lifting parts. The max pilot (actually payload, pilot / parachute / ballast weights / onboard snacks etc) weight is then the lower of: a) Weight of the actual non-lifting parts subtract from the manuals max non-lifting parts weight of 230kg (507lbs). Or b) 115kg (253.4lbs) which the manuals max pilot weight. Or c) The max all up weight less the empty weight (very unlikely to come into play) This all assumes that the empty CofG limit is inside the manual limitations. The max weight without water is not relevant and most new aircraft don't list it. You know the max non-lifting parts weight (the critical point due to bending loads), and the max all up weight inc water (undercarriage/structural and flight stress loads), then the difference has to be all in the wings. The aircraft doesn't know if the wings weight is structure or water so is happy to fly! -- Dan, 5J "Max weight of non lifting components (everything except wings)" - from BGA TCDS. Flight manual is silent on what it is. From https://members.gliding.co.uk/wp-con...312108_4-1.pdf , "AMP4-1/Nov 05 BGA AMP Part 4, Leaflet 4-1, Page 1 BGA AIRWORTHINESS AND MAINTENANCE PROCEDURES PART 4, LEAFLET 4-1 GLIDER WEIGHT AND BALANCE", "on-Lifting Parts: "For sailplanes where the Leading Particulars specify a maximum weight of non-lifting parts, it will additionally be necessary to weigh the wings to enable the weight of the fuselage and tailplane to be calculated; this is the empty weight of non-lifting parts. " CS-22 doesn't appear to talk about it. |
