  • E. Runway Length Analysis
    JOSLIN FIELD, MAGIC VALLEY REGIONAL AIRPORT DECEMBER 2012 E. Runway Length Analysis This appendix describes the runway length analysis conducted for the Airport. Runway 7-25, the Airport’s primary runway, has a length of 8,700 feet and the existing crosswind runway (Runway 12-30) has a length of 3,207 feet. A runway length analysis was conducted to determine if additional runway length is required to meet the needs of aircraft forecasted to operate at the Airport through the planning period. The analysis was conducted according to Federal Aviation Administration (FAA) guidance contained in Advisory Circular (AC) 150/5325-4B, Runway Length Requirements for Airport Design. The runway length analysis set forth in AC 150/5325-4B relates to both arrivals and departures, although departures typically require more runway length. Runway length requirements were determined separately for Runway 7-25 and Runway 12-30. E.1 Primary Runway Length Requirements According to AC 150/5325-4B, the design objective for the primary runway is to provide a runway length for all aircraft without causing operational weight restrictions. The methodology used to determine required runway lengths is based on the MTOW of the aircraft types to be evaluated, which are grouped into the following categories: Small aircraft (MTOW of 12,500 pounds or less) – Aircraft in this category range in size from ultralight aircraft to small turboprop aircraft. Within this category, aircraft are broken out by approach speeds (less than 30 knots, at least 30 knots but less than 50 knots, and more than 50 knots). Aircraft with approach speeds of more than 50 knots are further broken out by passenger seat capacity (less than 10 passenger seats and 10 or more passenger seats).

It is anticipated that a greater number of Flight Data Analysis Programs will lead to significantly greater safety levels through analysis of critical event sets and incidents. Action: The FDAP working group is requesting support for greater implementation of FDAP/FDMP throughout the Pan American Regions and consideration of new ICAO standards through the actions outlined in Section 4 of this working paper.

The proposed approach is integrated, as it allows an early estimation of main aircraft aerodynamic features, namely the maximum lift-to-drag ratio and the total parasitic drag. First, the influence of the Lift and Load scatterings on the overall performance characteristics of the wing are discussed. It is established that the optimization is achieved by designing a wing geometry that yields elliptical lift and load distributions. Second, the reference trapezoidal wing is considered the base line geometry used to outline the wing shape layout. As such, the main geometrical parameters and governing relations for a trapezoidal wing are

In addition, the earlier results (NASA CR-4592) for May 1990 scheduled air traffic have been updated using improved algorithms. These emissions inventories were developed under the NASA High Speed Research Systems Studies (HSRSS) contract NAS1-19360, Task Assignment 53. They will be available for use by atmospheric scientists conducting the Atmospheric Effects of Aviation Project (AEAP) modeling studies. A detailed database of fuel burned and emissions [NOx, carbon monoxide(CO), and hydrocarbons (HC)] for scheduled air traffic has been calculated for each month of 1992. In addition, the emissions for May 1990 have been recalculated using the same methodology. The data are on a 1° latitude x 1° longitude x 1 km altitude grid.
