A Conceptual Design of a Short Takeoff and Landing Regional Jet Airliner
A Conceptual Design of a Short Takeoff and Landing Regional Jet Airliner Andrew S. Hahn 1 NASA Langley Research Center, Hampton, VA, 23681 Most jet airliner conceptual designs adhere to conventional takeoff and landing performance. Given this predominance, takeoff and landing performance has not been critical, since it has not been an active constraint in the design. Given that the demand for air travel is projected to increase dramatically, there is interest in operational concepts, such as Metroplex operations that seek to unload the major hub airports by using underutilized surrounding regional airports, as well as using underutilized runways at the major hub airports. Both of these operations require shorter takeoff and landing performance than is currently available for airliners of approximately 100-passenger capacity. This study examines the issues of modeling performance in this now critical flight regime as well as the impact of progressively reducing takeoff and landing field length requirements on the aircraft’s characteristics. Nomenclature CTOL = conventional takeoff and landing FAA = Federal Aviation Administration FAR = Federal Aviation Regulation RJ = regional jet STOL = short takeoff and landing UCD = three-dimensional Weissinger lifting line aerodynamics program I. Introduction EMAND for air travel over the next fifty to D seventy-five years has been projected to be as high as three times that of today. Given that the major airport hubs are already congested, and that the ability to increase capacity at these airports by building more full- size runways is limited, unconventional solutions are being considered to accommodate the projected increased demand. Two possible solutions being considered are: Metroplex operations, and using existing underutilized runways at the major hub airports. -

Advisory Circular 120-62
fw 3 Advisory U.S.Department of Transportation Federal Aviation Circular ’ AdminisWation Qlbject: TAKEOFF SAFETY TRAINING AID bte: g/Q/g4 AC No. 120-6.2 Announcement Of Availability Initiatedby: AFS-210 Change; 1 PURPOSE. This advisory circular (AC) announces the availability of a joint industry/Federal Aviation Administration (FAA) Takeoff Safety Training Aid to help air carriers and pilots increase safety during the takeoff phase of flight. a. The FAA recommends early consideration of the information contained in the aid and use of the material, as appropriate, for training aircrews. This AC also highlights certain key items, concepts, and definitions that each air carrier or operator should address in their respective operational procedures and crew qualification programs. b This circular applies to Federal Aviation Regulations (FAR) Part 121 operators. However, many of the principles, concepts, and procedures described apply to operations under FAR Parts 918 129, and 135 for certain aircraft, and are recommended for use by those operators when applicable. 2 BACKGROUND. Takeoff accidents resulting from improper rejected takeoff (RTO) decisions and procedures are significant contributors to worldwide commercial aviation accident statistics. For those takeoffs that are rejected, and for takeoffs made under certain environmental conditions and with certain system failures, risks could be reduced by a higher level of flightcrew knowledge and by the use of improved procedures. Due to the risks and the accident statistics associated with takeoffs, a joint FAA/industry team studied what actions might be taken to increase takeoff safety. These studies included simulation trials and in-depth analysis of takeoff accidents and incidents. -

A SEMI-EMPIRICAL METHODOLOGY for BALANCED FIELD LENGTH ESTIMATION of JET- ENGINED AIRCRAFT in EARLY DESIGN PHASES Tulio Angeiras Embraer S.A
A SEMI-EMPIRICAL METHODOLOGY FOR BALANCED FIELD LENGTH ESTIMATION OF JET- ENGINED AIRCRAFT IN EARLY DESIGN PHASES Tulio Angeiras Embraer S.A. and Aeronautical Technology Institute – ITA Product Development Engineer and Graduate Student Sao Jose dos Campos, SP, 12227-901, Brazil [email protected] Adson de Paula (ITA), Bento Mattos (ITA), Tarik Orra (Embraer) ABSTRACT Current levels of competitiveness displayed in business and commercial aviation market led to increasingly stringent performance and economy requirements. One of the key elements of these requirements is field performance, a factor that has great influence on the viability of certain route or operation for the aircraft in question, and that might shift the balance in a purchase decision. During early design phases, aerodynamic data about the aircraft being developed is often inaccurate and subject to changes during its evolution, which, alongside with difficulties do validate the results, renders numerical simulation methods unpractical for estimating field performance. These factors stimulated the development of a number of semi-empirical methodologies to estimate takeoff field lengths, of which some, by taking advantage of the available historical trend, produce very reasonable results and are widespread adopted on the aviation industry. Aiming to enable leaner aircraft designs, this paper presents an overview of several established methods, analyzing structure and comparing results obtained by their application to a databank of existing aircrafts. Finally, it -
Appendix a Description of Declared Distances
Appendix A Description of Declared Distances Declared distances at airports are a mechanism by which specific lengths of runway pavement are identified for use in aircraft operations. Declared distances are incorporated into the Operations Specifications of commercial aircraft operators that are part of the air carrier certificates and operations certificates issued by FAA under 14 CFR Part 119, as well as into the internal operations manuals of those operators. Pilots of commercial aircraft are required to comply with such specifications and manuals. The specified distance available for a particular operation such as landing may be different in each direction on the same runway pavement. The FAA defines four declared distances: • Takeoff Run Available (TORA) – the runway length declared available and suitable for satisfying takeoff run requirements. The TORA is measured from the start of takeoff to a point 200 feet from the beginning of the departure Runway Protection Zone. • Takeoff Distance Available (TODA) – this distance comprises the TORA plus the length of any remaining runway or clearway beyond the far end of the TORA. • Accelerate-Stop Distance Available (ASDA) – the runway plus stopway length declared available and suitable for the acceleration and deceleration of an aircraft that must abort its takeoff. A stopway is an area beyond the takeoff runway able to support the airplane during an aborted takeoff, without causing structural damage to the airplane. • Landing Distance Available (LDA) – the runway length that is declared available and suitable for satisfying aircraft landing distance requirements. The figure below illustrates how declared distances allow a runway pavement length of 11,600 feet to provide a usable runway length of 10,000 feet for landing and 10,600 feet for takeoffs in both directions while still providing the FAA-required runway safety area dimensions of 600 feet prior to the landing threshold and 1,000 feet beyond the runway end. -
