Airplane Design
Do a conceptual design of a propeller driven six place single-engine airplane powered by
a 260 hp engine driving a constant speed propeller.
Your plane must have a maximum stall speed (you can use flaps) of 61 kts to meet FAR

Airplane Performance Spreadsheet Part I
The Drag Polar
Our goal is to develop a series of spreadsheets (or computer program) to evaluate the performance of a
propeller/reciprocating engine driven airplane. This is the first step in that process.
