Depending on the country, there may be a requirement for some minimum number of training hours to have been completed by the student pilot before they are allowed to solo. In most countries, it is assumed that such students will be familiar with (and may have to pass an examination on) the relevant air laws or regulations, and will have completed exercises in handling aircraft in normal conditions, and also what to do in the case of engine failure on takeoff, in flight, and before landing. In the United States, for most aircraft, there is no FAA (
Federal Aviation Administration) requirement for a minimum number of hours, but a
student pilot certificate is required. Per FAR Part 61 SFAR 73 section 2, Robinson helicopters have a 20-hour requirement to solo. However, the regulations do require that a student pilot show competency in several specific skills to include, for example, the ability to
forward slip. In practice, competence is mostly a judgment call of the
Certificated Flight Instructor (CFI) responsible for the student. Typically, it takes from 10 to 30 hours of flight time before a pilot has the instinctive feel of an aircraft to be safe flying solo in other than perfect (no wind) weather. == Soloing ==
