Presentation outline. Why do we have this workshop? Annual Meeting 11 September, 2010 The Sheraton, Mahwah, NJ -.Surface course may also be specified but only for those pavements designed to accommodate aircraft of gross weights less than or equal to 12,500 pounds (5,670 kg) or for surface course of shoulders, blast pads, service roads, etc. Item P-401 is to be specified for surface courses for pavements designed to accommodate aircraft gross weights greater than 12,500 pounds (5,670 kg). This specification is to be used as a base or leveling course for pavements designed to accommodate aircraft of gross weights greater than 12,500 pounds (5,670 kg). State highway department specifications may be used in lieu of this specification for access roads, perimeter roads, stabilized base courses under Item P-501, and other pavements not subject to aircraft loading, or for pavements designed for aircraft gross weights of 12,500 pounds (5,670 kg) or less.

Where a state highway department specification is to be used in lieu of this specification, the state specification must have a demonstrated satisfactory performance record under equivalent loadings and exposure. The same grade PG binder used by the state highway department in the area should be considered as the base grade for the project (e.g. the grade typically specified in that specific location for dense graded mixes on highways with design Equivalent Standard Axle Loads (ESALS) less than 10 million). The exception would be that grades with a low temperature higher than PG XX-22 should not be used (e.g. PG XX-16 or PG XX-10), unless the Engineer has had successful experience with them. Typically, rutting is not a problem on airport runways. However, at airports with a history of stacking on end of runways and taxiway areas, rutting has accrued due to the slow speed of loading on the pavement. Each grade adjustment is 6 degrees C. Polymer Modified Asphalt, PMA, has shown to perform very well in these areas. The low temperature grade should remain the same. Our services range from individual testing to full-time field observation and inspection. These are important to both contractors and owners in providing assurance that contract specifications are being met. Projects Worked On: New York State Thruway, Route 81, Niagara Falls International Airport, Syracuse Hancock International Airport, Oswego County Airport and Essex County Airport to name a few. The new airport opened on July 1, 1970, with a single 6,500-foot (2.0 km) runway; the previous smaller airstrip was converted into the Old Kona Airport State Recreation Area.The aquaculture ponds and solar energy experiments at the nearby Natural Energy Laboratory of Hawaii Authority (NELHA) can be seen during landing and take-off.Airport operations falls under the State of Hawaii Department of Transportation.The airport terminal is a rambling, open-air set of structures.


The United States Air Force investigated building a second 3,950 ft (1,200 m) runway in 2009.The pilot and passenger were killed.The displays included a sample of lunar soil, a space suit from Apollo 13, and personal items from Onizuka.Tourists to the Kona side of the Island typically flew into Hilo and drove across the island.By 2005 the percentage of accommodations on the West side increased to 86 of the total.This second terminal will serve overseas and international passengers. When not in international use the new gates, accessed via jet bridge from the second story, will be used for interisland flights. The location of the second story will be on the west side of the current terminal locations, serving to physically connect the two terminals. For this to happen, the Ellison S. Onizuka Space Center would have been relocated.Effective May 30, 2015. Ulukau, the Hawaiian Electronic Library, University of Hawaii Press. Retrieved September 21, 2010.

Where a tolerance on the highest rotor speed is specified, the maximum normal operating rotor speed is the highest rotor speed for which that tolerance is given. If the rotor speed is automatically linked with flight condition, the maximum normal operating rotor speed corresponding with the reference flight condition must be used during the noise certification procedure. If rotor speed can be changed by pilot action, the highest normal operating rotor speed specified in the flight manual limitation section for reference conditions must be used during the noise certification procedure.These are default positions used to refer to normal nacelle positioning operation of the aircraft. The nacelle angle is controlled by a self-centering switch.

When the nacelle angle is 0 degrees (airplane mode) and the pilot moves the nacelle switch upwards, the nacelles are programmed to automatically turn to the first default position (for example, 60 degrees) where they will stop. A second upward move of the switch will tilt the nacelle to the second default position (for example, 75 degrees). Above the last default position, the nacelle angle can be set to any angle up to approximately 95 degrees by moving the switch in the up or down direction. The number and position of the fixed operation points may vary on different tiltrotor configurations.When the time interval between the date of application for the type certificate and the issuance of the type certificate exceeds 5 years, the applicant must show that the aircraft meets the applicable requirements of this part that were effective on a date, to be selected by the applicant, not earlier than 5 years before the issue of the type certificate.No determination is made, under this part, that these noise levels are or should be acceptable or unacceptable for operation at, into, or out of, any airport. All approved material is available for inspection at the locations in this paragraph (a) and may be obtained from the sources detailed in paragraphs (a)(1) through (12) of this section.For information on the availability of this information at NARA, call 202-741-6030 or go to Except as otherwise specifically provided, for each airplane covered by this section, the acoustical change approval requirements are as follows: For each Stage 1 airplane prior to the change in type design, in addition to the provisions of paragraph (b) of this section, the following apply: The tradeoff provisions of section B36.6 of appendix B of this part may not be used to increase the Stage 1 noise levels, unless the aircraft qualifies as a Stage 2 airplane.

If an airplane is a Stage 2 airplane prior to the change in type design, the following apply, in addition to the provisions of paragraph (b) of this section:For an airplane that has jet engines with a bypass ratio of 2 or more before a change in type design - For an airplane that does not have jet engines with a bypass ratio of 2 or more before a change in type design - If an airplane is a Stage 3 airplane prior to the change in type design, the following apply, in addition to the provisions of paragraph (b) of this section:Compliance must be shown under the provisions of paragraph (e)(2) of this section. If an airplane is a Stage 5 airplane prior to a change in type design, the airplane must remain a Stage 5 airplane after the change in type design.Except as otherwise provided, for helicopters covered by this section, the acoustical change approval requirements are as follows:For helicopters having a maximum certificated takeoff weight of not more than 7,000 pounds that alternatively demonstrate compliance under appendix J of this part, the flyover noise level prescribed in appendix J of this part must be measured, evaluated, and calculated in accordance with the applicable procedures and conditions prescribed in parts B and C of appendix J of this part.For those helicopters that demonstrate compliance with the requirements of appendix J of this part, compliance with the noise levels prescribed in section J36.305 of appendix J of this part must be shown in accordance with the applicable provisions of part D of appendix J of this part.The tradeoff provisions under section H36.305(b) of appendix H of this part may not be used to increase any Stage 1 noise level beyond these limits. If an applicant chooses to demonstrate compliance under appendix J of this part, for each Stage 1 helicopter prior to a change in type design, the helicopter noise levels may not, after a change in type design, exceed the Stage 2 noise levels specified in section J36.

305(a) of appendix J of this part.For each helicopter that is Stage 2 prior to a change in type design, after a change in type design the helicopter must either:For a helicopter that is a Stage 3 helicopter prior to a change in type design, the helicopter must remain a Stage 3 helicopter after a change in type design.
