What are the two major categories of pavement? ✔✔ Flexible and rigid
What are some types of flexible pavement? ✔✔ Grass, dirt, gravel and
... [Show More] asphalt
Why are paved surfaces necessary at airports? ✔✔ To support the critical loads
imposed on them; to produce a smooth, skid-resistant and safe-riding surface
What is the benefit of using a rigid pavement such as Portland Cement Concrete? ✔✔ It
is about half the lifetime cost of asphalt, with a service life of 30+ years versus 5-15
years for asphalt. Concrete is more expensive up front though, so asphalt is common at
low revenue airports such as GA.
What are two major elements that make pavements deteriorate? ✔✔ weathering and
aircraft loads
For bearing strengths of 12,500lbs or greater, what method is used to express the effect
of an individual aircraft on different pavements? ✔✔ Comparing ACN to PCN (Aircraft
Classification Number-Pavement Classification Number) ACN less than or equal to PCN
What does the Pavement Classification Number (PCN) represent to the operator/pilot?
✔✔ PCN is the maximum pavement bearing strength for unrestricted aircraft operations.
What is the Load Classification Number (LCN) used to describe? ✔✔ Pavement bearing
strengths less than 12,500lbs
What are the five major categories of pavement distress? ✔✔ cracking, joint seal
damage, disintegration, distortion, loss of skid resistance
How far are landing distances increased on wet pavement? ✔✔ By 15 percent or more
Where are wind cones located? ✔✔ at least one on the airport, lighted if night carrier
operations occur; additional cones placed so that every takeoff and landing runway has
a cone visible to pilots
When must an airport operator conduct an airfield self-inspection? ✔✔ daily; when
required by an unusual condition; immediately after an accident or incident
How long must airfield self-inspection records be kept? ✔✔ 12 consecutive calendar
months
How often must operations personnel be trained on self-inspection related activities and
how long must training records be kept? ✔✔ training every 12 consecutive calendar
months, records maintained for 24 months
How long must a record of airfield condition NOTAMs be kept? ✔✔ 12 months
What are four types of inspections? ✔✔ Regular scheduled; continuous surveillance;
periodic; special
How is safety oversight defined? ✔✔ those means and activities by which airport
management ensures effective implementation of safety-related standards and
procedures [Show Less]
