4. EVALUATION METHOD. The ACN/PCN system also requires a reporting of the general basis of
evaluation. Code T will indicate a technical evaluation of the type prescribed herein. Thus, any evaluation
following this manual will be reported as a technical evaluation (T). Where the reported PCN must be
based only on knowledge of the heaviest aircraft using a facility and without a specific evaluation, it will be
reported as a "using aircraft" evaluation (Code U).
5. CODED REPORTING IN FLIGHT INFORMATION PUBLICATION (FLIP) OR AIRFIELD INFORMA-
TION PUBLICATION (AIP) DOCUMENTS. The coding indicated permits a greatly abbreviated reporting
of the PCN and related information for use in FLIP or AIP type documents as used by the Defense Depart-
ment (NIMA) or the civil (FAA) and international (ICAO) communities. Following is an example of coded
reporting with explanatory notes.
Example PCN Code = 39/F/C/X/T where:
39 = PCN value established
F = Flexible pavement
C = Low-strength subgrade (between 4 and 8 CBR)
X = Limited to medium tire pressures (less than 217 psi)
T = Technical evaluation
