Figures 2-1 through 2-8 show how these VLJ designs com- pare with other existing piston, turboprop, and light jet aircraft (including new generation aircraft). For reference purposes, popular traditional aircraft (e.g., the Beechcraft Baron G58 piston, the Cessna Grand Caravan turboprop, and the Beechcraft C90 King Air turboprop) are included as well.

Under FAR Part 135, an aircraft must be fully stopped within 60% of the available runway length (80% if the airport is an approved Destination Airport in the operator's manual.) For both takeoffs and landings, runway length requirements are affected by many operating conditions and variables, including runway elevation and gradient, temperature, atmospheric pressure, wind, surface conditions, aircraft load factor and payload. Figure 2-1 compares the runway requirements for various small GA aircraft using the Balanced Field Length (BFL) metric. Although this is a useful metric, the graph is meant only to allow one to compare the relative requirements between different aircraft. The actual runway length required Table 2-2.
