2.8 Weight and Balance Information
Weights starting:
Minimum load with ballast on front seats, 122 lb 55 kg
Maximum load on front seats, w/o ballast 489 lb 220 kg
Maximum take off weight 1320 lb 600 kg
Baggage weight (limited b MTOW) 44 lb 20 kg
Empt weight (standard ULM) 715 lb 325 kg
Empt weight (Fixed Wing) 753 lb 342 kg
Empt weight (Foldable Wing) 818 lb 350 kg
Datum line is wing leading edge
Level line is wing lower surface, at root section, with 4,6 degrees positive.
Baggage is located ver close to CG position, so limit of baggage weight is onl limited b maximum
take off weight.
Leveling: The airplane should be leveled b the bottom of the wing with + 4, 6 degrees positive.
Main landing gear wheels should be positioned over level blocks. Depending on shock absorbers on
main landing gear, those blocks probabl will have different heights in different airplanes.
Measuring: Measurement should be taken with a bob weight, marked on ground and then
measured.
Weighting: Using one or three scales, the airplane should sta on same level for weighting.
