PCN is now mandatory and Gross Weight data will possibly be phased out with time. Any rational design procedure developed specifically for airport pavements but applied in reverse for pavement evaluation. This increases the conservatism of this particular design and may force the B to become the design airplane rather than some of the other models with relatively high departure levels. Repeat with each airplane the critical airplane. To make this website work, we log user data and share it with processors. This is true for either the D procedure or the PCA center slab procedure. CBR 9 indicates B subgrade designation.

Determine ACN of critical airplane at allowable weight. Next, click on Form tab.
Large softwate of narrow-body, dual-wheel-gear aircraft. Published by Brittany Richardson Modified over 4 years ago. This increases the conservatism of this particular design and may force the B to become the design airplane rather than some of the other models with relatively high departure levels. For each aircraft, allowable gross weight and corresponding PCN are identified. Draft AC was posted for comment October The CDF procedure is used for equivalent coverages.
If the PCA design method is employed center slab rather than edge load then the 2D gear airplanes tend to have greater impact on the design. ENTER all existing pavement layers starting at the surface of the pavement. PCN - A number expressing the bearing strength of a pavement for unrestricted operations.
Configuring Application Restriction Policies. Next, click Rigid Chart tab. Feedback Privacy Policy Feedback. During each airport inspection, the airport owner will be asked to provide runway PCN information. S — Teknik Jalan Raya Tahun: ENTER all existing pavement layers.

PCA Westergaard interior stress method of design. The PCN procedures in the manual are for guidance only and a great deal of latitude is provided. Welcome to a tour of Limb Volumes Professional 6. To make this website work, we log user data and share it with processors.
Airport operators are responsible for determining and publishing PCN values for runways. Aircraft manufacturers are required to publish properly computed ACN values for all of their aircraft.
COMFAA 3.0 Beta.
PCN data request now part of all airport inspections The Master Record is required to be updated periodically. These are fixed, standard procedures. Determine softwate operating weight of critical airplane. We also speculate that the maximum gross weight for the B is considerably higher than many of the models used to generate the annual departure level. The spreadsheet updates the graphical representation of the existing and equivalent pavement.
The PCNwg questioned whether the B should be the design airplane, however, none of the 2D gear airplanes generate much pavement thickness requirement.
