Vehicle Sizing
Determine Wing Loading, Planform Area
Select Aspect Ratio
Span & Chord
Select Airfoil
Consider All Elements of Performance (C
Lmax
, stall performance, drag)
Consider Reasonable Building Constraints (such as trailing edge thickness) and their Impact Upon Performance

Configuration Selection
Conventional, Canard, Tailless Flying Wing, Delta, Biplane, Monoplane, etc.
Analyze
the pros & cons of each
Select based upon best fit with design objectives
Pay Attention to Requirements
Tricycle or Taildragger
Don’t Halt Analysis at Weight Only
Consider the Operating Environment!
Wing Placement: High, Mid, Low
Consider Stability Implications
Structural Implications
Propulsion Installation
