A general aviation single engine aircraft has gross weight of 2800lb. The aircraft has maximum speed of 130mph. Determine the approximated value of empty weight fraction if, aspect ratio AR is 9, wing loading is 15 and power loading is 12.

Initial Sizing topics include: Rubber engine sizing, fixed engine sizing, geometry and control surface sizing. Initial sizing is the first step in aircraft design. It defines the rough size and weight of an aircraft based on its intended requirements. Initial sizing includes: Weight and volume estimations Constraint analysis for the thrust-to-weight ratio Wing loading Visual analysis of the available design space with respect to performance constraints Selection of the optimum design point (P/W and W/S) and the corresponding HP Engine characteristics and aerodynamic...

Initial sizing is the first step in aircraft design. It defines the rough size and weight of an aircraft based on its intended requirements.

Initial sizing includes:
Weight and volume estimations
Constraint analysis for the thrust-to-weight ratio
Wing loading
Visual analysis of the available design space with respect to performance constraints
Selection of the optimum design point (P/W and W/S) and the corresponding HP
Engine characteristics and aerodynamic characteristics
Sizing of an aircraft's mass, wing area, and propulsion system 

Initial sizing can also include point- and mission performance analysis.
