Document Title: AC 136-B048, Supplemental Information for the Creation of Operating Procedures and Pilot Training Subjects Related to OpSpec/LOA B048
Summary: The information provided in this AC is intended to assist certificate holders (CH) and operators with the development of operational processes and procedures and the pilot training recommended as part of the Operations Specification (OpSpec)/Letter of Authorization (LOA) B048, Commercial Air Tour Operations Below 1,500 Feet Above the Surface in the State of Hawaii, application package. OpSpec/LOA B048 provides the CH or operator with authorization to conduct commercial air tour operations below 1,500 feet above the surface in the State of Hawaii in order to remain in visual meteorological conditions (VMC) and avoid entering unforecasted instrument meteorological conditions (IMC). The authorization is not intended to be used for flight planning, and does not authorize a CH or operator to conduct a commercial air tour operation when the forecasted weather conditions would not permit the operation to remain in VMC at altitudes above 1,500 feet above the surface for the duration of the planned flight.
