This one-half day, 4-hour combined classroom and simulator course is designed to meet the ground training requirements of FAR 61.31(g). “Additional training required for operating pressurized aircraft capable of operating at high altitudes.” This regulation states, with a few exceptions, that no person may act as pilot in command of a pressurized aircraft (an aircraft that has a service ceiling or maximum operating altitude, whichever is lower, above 25,00 feet MSL), unless that person has received and logged ground training from an authorized instructor and obtained an endorsement in the person’s logbook or training recored from an authorized instructor who certifies the person has satisfactorily accomplished the ground training.
