Background

The proposed interim policy memorandum provides Federal Aviation Administration (FAA) certification policy on the compliance issues associated with high altitude flight. This memo provides applicants with information on how the FAA will evaluate petitions for exemption from § 25.841(a), as amended by Amendment 25-87. For airplanes with wing-mounted engines, this regulation in effect limits the maximum operating altitude of airplanes approved to this standard to 40,000 feet. Several airframe manufacturers have asked the FAA to develop a new safety standard, which is being addressed in rulemaking activities. Those manufacturers have also asked for interim policy to provide relief because high altitude flight offers benefits to airplane performance in terms of reduced drag and lower fuel burn.
