1.221J/11.527J/ESD.201J – Transportation Systems Assignment 1- Fall 2004 SMALL AIRCRAFT TRANSPORTATION SYSTEMS Philippe A. Bonnefoy INTRODUCTION Air transportation systems are based on a variety of vehicles including fixed wing aircraft and helicopters. The most diverse and developed category remains the fixed wing aircraft with sizes ranging from single seat to 555 seats in the case of the Airbus A380. This size characterization relates to passenger vehicles. However, cargo aircraft have similar range of sizes. The largest fraction of commercial air transportation is performed using 50 to 300 seat aircraft. However, there exists a segment of the air transportation market that relies on smaller vehicles. OVERVIEW OF CURRENT SMALL AIRCRAFT TRANSPORTATION SYSTEMS For the purpose of this study, small aircraft were defined as aircraft able to transport from 2 passengers, like the Cessna 172 or the Piper PA28 aircraft up to 12 passengers such as Gulfstream V or similar business jets. Of course, similar size aircraft used for freight transportation are included in the analysis. As shown on Table 1, the largest fraction of small aircraft is powered by piston engines with 170,500 registered aircraft in the United States in 2001. However, compared with the size of the fleet of major airlines like American Airlines (over 800 aircraft), the number of jet aircraft is significant with 7000 aircraft operated in the United States in 2001. Turboprops are the least numerous category with 5800 registered aircraft. ------------------------------------ Piston 170,500 Turboprop 5,800 Jet 7,000 ------------------------------------ Total 183,300 ------------------------------------ Table 1: Number of aircraft by type [1]. Modes of Operation Because from an acquisition and operating cost perspective, small aircraft are much more accessible than their larger counterparts, the modes of operation are much more diverse. General Aviation General aviation is the term used to define [2] aircraft operations that encompass all civil aviation other than scheduled airline flights and military aviation. It includes everything from a privately-owned light single-engine aircraft to business jets, police, pipeline patrol, emergency medical flights, crop-dusting, rotorcraft, sport ballooning and many other aerial activities. From an operational perspective, general aviation 1

1.221J/11.527J/ESD.201J – Transportation Systems Assignment 1- Fall 2004 operations can be segregated into three major categories. Table 2 shows the utilization of aircraft for various type of flying. The activity where most of the vehicles are used is the “personal” category. This category is probably the most heterogeneous in term of operations since it regroups everything from non transportation activity such as leisure flying around an airport, antique aircraft collection to transportation purposes like private pilots owning their aircraft and using it as a substitute to other modes of transportation. ------------------------------------
