  • Flight Inspection History Written by Scott Thompson - Sacramento Flight Inspection Office (May 2008)
    Flight Inspection History Written by Scott Thompson - Sacramento Flight Inspection Office (May 2008) Through the brief but brilliant span of aviation history, the United States has been at the leading edge of advancing technology, from airframe and engines to navigation aids and avionics. One key component of American aviation progress has always been the airway and navigation system that today makes all-weather transcontinental flight unremarkable and routine. From the initial, tentative efforts aimed at supporting the infant air mail service of the early 1920s and the establishment of the airline industry in the 1930s and 1940s, air navigation later guided aviation into the jet age and now looks to satellite technology for direction. Today, the U.S. Federal Aviation Administration (FAA) provides, as one of many services, the management and maintenance of the American airway system. A little-seen but still important element of that maintenance process is airborne flight inspection. Flight inspection has long been a vital part of providing a safe air transportation system. The concept is almost as old as the airways themselves. The first flight inspectors flew war surplus open-cockpit biplanes, bouncing around with airmail pilots and watching over a steadily growing airway system predicated on airway light beacons to provide navigational guidance. The advent of radio navigation brought an increased importance to the flight inspector, as his was the only platform that could evaluate the radio transmitters from where they were used: in the air. With the development of the Instrument Landing System (ILS) and the Very High Frequency Omni-directional Range (VOR), flight inspection became an essential element to verify the accuracy of the system.

  • Air Navigation
    Air Navigation Professor Dr. Paul Stephen Dempsey Director, Institute of Air & Space Law McGill University Copyright © 2008 by the author. The Importance of Air Navigation Air navigation services are manifestly important to the safety and efficiency of air transportation. Safety and security of flight depend upon the proficiency of their provision. They impact airline economics both in terms of the charges they impose upon users of the system, and the delay and circuity they can impose on aircraft operations. “Among the traditional functions of government, air traffic control is provided for the purpose of preventing collisions between aircraft in the air and between aircraft and obstructions on the ground, as well as expediting and maintaining an orderly flow of air traffic. In addition to ATC, the effective management of air traffic requires associated services such as meterology, search and rescue, and telecommunications, as well as the provision of aeronautical information such as charts.” Ira Lewis The Chicago Convention of 1944 •Article 1 – Each State has complete and exclusive sovereignty over its airspace; •Article 5 – States may prescribe specific routes for non- scheduled flights; •Article 6 – Scheduled flights may not be conducted over the territory of another State without its authorization; •Article 8 – No pilotless aircraft may be flown over the territory of another State without special permission; Designated Routes and Prohibited Areas Article 68 – Each State may designate international air routes and international airports

C. Inertial navigation systems – Autonomous navigation systems based on inertial forces, providing constant information on the position of the flight and parameters of speed and direction (e.g. when flying above the ocean and there are no ground segments to provide support). Requirements for performance of Navigation Systems: According to the International Civil Aviation Organization (ICAO) there are four main requirements: • The accuracy means the level of concordance between the estimated position of an aircraft and its real position. • The availability is the portion of time during which the system complies with the performance requirements under certain conditions. • The integrity is the function of a system that warns the users in an opportune way when the system should not be used.

  • Chapter: 2. En Route Operations
    Chapter 2 En Route Operations Introduction The en route phase of flight is defined as that segment of flight from the termination point of a departure procedure to the origination point of an arrival procedure. The procedures employed in the en route phase of flight are governed by a set of specific flight standards established by 14 CFR [Figure 2-1], FAA Order 8260.3, and related publications. These standards establish courses to be flown, obstacle clearance criteria, minimum altitudes, navigation performance, and communications requirements. 2-1 fly along the centerline when on a Federal airway or, on routes other than Federal airways, along the direct course between NAVAIDs or fixes defining the route. The regulation allows maneuvering to pass well clear of other air traffic or, if in visual meteorogical conditions (VMC), to clear the flightpath both before and during climb or descent. Airways Airway routing occurs along pre-defined pathways called airways. [Figure 2-2] Airways can be thought of as three- dimensional highways for aircraft. In most land areas of the world, aircraft are required to fly airways between the departure and destination airports. The rules governing airway routing, Standard Instrument Departures (SID) and Standard Terminal Arrival (STAR), are published flight procedures that cover altitude, airspeed, and requirements for entering and leaving the airway. Most airways are eight nautical miles (14 kilometers) wide, and the airway Figure 2-1.

  • FAA-H-8083-15, Instrument Flying Handbook -- 1 of 2
    i ii Preface This Instrument Flying Handbook is designed for use by instrument flight instructors and pilots preparing for instrument rating tests. Instructors may find this handbook a valuable training aid as it includes basic reference material for knowledge testing and instrument flight training. Other Federal Aviation Administration (FAA) publications should be consulted for more detailed information on related topics. This handbook conforms to pilot training and certification concepts established by the FAA. There are different ways of teaching, as well as performing, flight procedures and maneuvers and many variations in the explanations of aerodynamic theories and principles. This handbook adopts selected methods and concepts for instrument flying. The discussion and explanations reflect the most commonly used practices and principles. Occasionally the word “must” or similar language is used where the desired action is deemed critical. The use of such language is not intended to add to, interpret, or relieve a duty imposed by Title 14 of the Code of Federal Regulations (14 CFR). All of the aeronautical knowledge and skills required to operate in instrument meteorological conditions (IMC) are detailed. Chapters are dedicated to human and aerodynamic factors affecting instrument flight, the flight instruments, attitude instrument flying for airplanes, basic flight maneuvers used in IMC, attitude instrument flying for helicopters, navigation systems, the National Airspace System (NAS), the air traffic control (ATC) system, instrument flight rules (IFR) flight procedures, and IFR emergencies. Clearance shorthand and an integrated instrument lesson guide are also included. This handbook supersedes Advisory Circular (AC) 61-27C, Instrument Flying Handbook, which was revised in 1980.

INSTRUMENT-NOT BLIND FLYING* HEUBERT W. ANDERSONt When a person is lost and wandering aimlessly in circles, per- haps through a dense forest or in desert land, his sense of direction is gone because he has no natural way of determining direction other than by visual reference to familiar objects. We lack what might be termed a-"compass" in our minds. We may become lost directionally on the ground or lost in all directions in the air. Air- plane pilots flying in fog or clouds are in what appears to be a gray globular mass where all sense of direction is lost. They not only must maintain the desired direction horizontally, but are re- quired to keep the airplane in the proper attitudes longitudinally and laterally. That the pilot is incapable of doing this without special instruments has been proved in many tests both in flight and on the ground. Majors Ocker and Crane' have made extensive re-- search on this subject, even demonstrating that blindfolded birds, when launched into the air, fluttered helplessly, and failed utterly in their attempts to maintain flight.
