Assignment 5: Geometric Design Standards

CEE 4674 Homework 5 Spring 2009c) If the runway shown in Figure 3 serves aircraft in approach speed categories A and B would it meet all the currentlongitudinal grade FAA standards. Explain.Figure 9. Runway Longitudinal Grades for Approach Categories A and B.The maximum longitudinal grades are below 2% (OK).The maximum grade change is below 2% (OK).The distance between points of intersection is 2742 feet. This easily meets the required minima (486 feet).The runway would comply with all requirements of approach categories A and B.Problem #3The new airport in Florida with a 9000 foot runway needs runway exits. The airport authority wants at least three 90 degreeexits for the runway to serve distinct aircraft groups shown in Table 1. These three exits are in addition to the 90 degree angleexits at the end points of the runway.Table 1. Aircraft Parameters for Problem 4. Refer to Matlab Code in Notes 9 Handout for Explanations. All other Parameters areAssumed to Take Values Defined in the Handout.Aircraft Group Parameters Representative Aircraft(REDIM Name)Small single-engine GA aircraftBusiness jetsMedium-size transport aircraftApproach speed = 110 knotsTouchdown location = 275 metersAverage deceleration = -1.3 m/s-sFree roll time = 2.5 secondsApproach speed = 125 knotsTouchdown location = 350 metersAverage deceleration = -1.4 m/s-sFree roll time = 2.0 secondsApproach speed = 140 knotsTouchdown location = 420 metersAverage deceleration = -1.4 m/s-sFree roll time = 2.0 secondsCessna 208 (CE-208), Beech F33 (BE-F33A)Cessna 550 (CE-550), Learjet 31(Learjet 31),Boeing 737-400 (B-737-400), AirbusA320 (A-320-200)a) Find three runway exit locations (one for each aircraft group) using the three point method. Consider that therunway is used from both directions. 6
