Basic Empty Weight (Oil) – Archer vs Warrior
Asked by: dudebro311 782 views Aerodynamics, Aircraft Systems, FAA Regulations, Flight Instructor, General Aviation
Given: we know Empty Weight excludes the weight of the crew and payload, but includes the weight of all fixed ballast, unusable fuel supply, undrainable oil, total quantity of engine coolant, and total quantity of hydraulic fluid (Ref: FAA).
Question: Why does the PA28-181 (Archer) include full oil in the empty weight calculation (Ref: POH VB-760 REV5 para 6.3.a.4) while the PA28-151 includes only undrainable oil? (Ref: POH VB-535 Page 5-3)?
