Air Carrier Maintenance Programs
This advisory circular (AC) explains what the term "maintenance program" means. Our explanation describes the scope and content of air carrier aircraft maintenance programs. This is important as there is a significant difference between an air carrier maintenance program and an inspection program used in non-air carrier maintenance operations. We explain the background of these programs as well as the Federal Aviation Administration’s (FAA) regulatory requirements. We also describe and explain each of the 10 elements of air carrier maintenance programs. When we use "must" or "will" in this AC, we are referencing actual regulatory requirements. When we use "we," "us," or "our" in this AC, we mean the FAA. When we use "you," "your," or "yours," we mean you, the air carrier. When we use the term "person," it has the same meaning as that in Title 14 of the Code of Federal Regulations (14 CFR) part 1, § 1.1.
Air Carrier Operational Approval and Use of TCAS II
This advisory circular (AC) provides an acceptable, but not the only, means to address Traffic Alert and Collision Avoidance System (TCAS) issues related to installation and use of TCAS II regarding compliance with Title 14 of the Code of Federal Regulations (14 CFR) parts 121, 125, and 129 requirements for air carriers.
Air Carrier Pilot Remedial Training and Tracking Program
This advisory circular (AC) presents guidelines for developing and implementing remedial training and tracking of pilots. These guidelines apply to certificate holders conducting operations under Title 14 of the Code of Federal Regulations (14 CFR) part 121. This AC presents one way, but not necessarily the only way, that certificate holders may comply with the remedial training and tracking requirements prescribed in 14 CFR part 121, § 121.415. This AC may also provide valuable information to certificate holders in developing and implementing remedial training and tracking of other crewmembers and aircraft dispatchers.

Aircraft Arresting Systems
Contains FAA standards and recommendations for the installations of aircraft arresting systems on civil airports not owned or operated by the U.S. Department of Defense (DOD). This AC does not describe Engineered Materials Arresting Systems (EMAS). For guidance on EMAS, see AC 150/5220-22, Engineered Materials Arresting Systems (EMAS) for Aircraft Overruns.
Aircraft Boarding Equipment
Contains the FAA's performance standards, specifications, and recommendations for the design, manufacture, testing and maintenance of equipment used in the boarding of airline passengers. The physical area covered in this AC is that which is bounded by the door of the passenger terminal area, on one end, to the door of the aircraft, on the other end. Although this AC refers only to aircraft boarding (enplaning), all references apply equally to disembarking (deplaning) with the described procedures occurring in reverse order.
The previous version of this AC discussed only the passenger lift scenario and associated equipment. This document updates that effort and addresses the other methods and equipment used to board an aircraft, including passenger boarding bridges, ramps, lifts, and aircraft boarding chairs.

Aircraft Operations at Altitudes Above 25,000 Feet Mean Sea Level or Mach Numbers Greater Than .75
This advisory circular (AC) alerts pilots transitioning from aircraft with less performance capability to complex, high-performance aircraft that are capable of operating at high altitudes and high airspeeds. In particular, this AC stresses special physiological, equipment, and aerodynamic considerations involved in these kinds of operations. It also provides information to aid pilots in becoming familiar with the basic phenomena associated with high-altitude and high-speed flight.
Title 14 of the Code of Federal Regulations (14 CFR) part 61 prescribes the knowledge and skill requirements for the various airman certificates and ratings, including category, class, and type ratings authorized to be placed thereon. The civil aircraft fleet consists of numerous aircraft capable of high-altitude flight. Certain knowledge elements of high-altitude flight are essential for the pilots of these aircraft. As required by 14 CFR § 61.31, pilots who fly at altitudes at or above FL250 in a pressurized aircraft must receive training in the critical factors relating to safe flight operations under those circumstances. These critical elements include knowledge of the special physiological and/or aerodynamic considerations that should be given to highperformance aircraft operating in the high-altitude environment. High-altitude flight has different effects on the human body than those experienced during lower altitude flight. An aircraft's aerodynamic characteristics displayed in high altitude flight may differ significantly from those experienced when penetrating at a lower altitude. Knowledge of and skill in operating high-performance aircraft will enhance the pilot's ability to easily transition into aircraft capable of high speed, high altitude flight.
