Cessna simultaneously developed the Citation Mustang,[22][19][20] a six-place twinjet (2 crew + 4 passengers), followed by the Embraer Phenom 100[22][19][20][21] and the Honda Jet.[19][21] They have a maximum takeoff weight lighter than the FAR Part 23 12,500 pounds limit, and are approved for single-pilot operation. They typically accommodate 5-7 passengers over a 965 nmi average range, with a $3.6M mean price. Some VLJs such as the Eclipse and Mustang have no or limited lavatory facilities.[23]
Charter, also called air taxi or ad-hoc flights require certification from the associated country's regulating body such as the FAA in the U.S. The regulations are differentiated from typical commercial/passenger service by offering a non-scheduled service. In the U.S. these flights are regulated under FAA Part 135[1]. There are some cases where a charter operator can sell scheduled flights, but only in limited quantities[2].
Aircraft charter brokers have entered the marketplace through the ease of setting up a website and business online. Aircraft charter operators are legally responsible for the safe operation of aircraft and charter brokers require no economic authority and are largely unregulated. The Department of Transportation requires that air charter brokers disclose to the consumer that they do not operate aircraft and cannot use terms like "our fleet of aircraft", "we operate", "our charter service" and others.[17]
