AAAE ACE Modules 1-4
What are the two major categories of pavement? CORRECT ANSWER -
Flexible and rigid
What are some types of flexible pavement? CORRECT ANSWER -
Grass, dirt, gravel and asphalt
Why are paved surfaces necessary at airports? CORRECT ANSWER -
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? CORRECT
ANSWER -
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? CORRECT ANSWER -
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? CORRECT ANSWER -
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? CORRECT
ANSWER -
PCN is the maximum pavement bearing strength for unrestricted aircraft operations.
What is the Load Classification Number (LCN) used to describe? CORRECT ANSWER -
Pavement bearing strengths less than 12,500lbs
What are the five major categories of pavement distress? CORRECT ANSWER -
cracking, joint seal damage, disintegration, distortion, loss of skid resistance
How far are landing distances increased on wet pavement? CORRECT ANSWER -
By 15 percent or more
Where are wind cones located? CORRECT ANSWER -
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? CORRECT ANSWER -
daily; when required by an unusual condition; immediately after an accident or incident
How long must airfield self-inspection records be kept? CORRECT ANSWER -
12 consecutive calendar months
How often must operations personnel be trained on self-inspection related activities and how long must
training records be kept? CORRECT ANSWER -
training every 12 consecutive calendar months, records maintained for 24 months
How long must a record of airfield condition NOTAMs be kept? CORRECT ANSWER -
12 months
What are four types of inspections? CORRECT ANSWER -
Regular scheduled; continuous surveillance; periodic; special
How is safety oversight defined? CORRECT ANSWER -
those means and activities by which airport management ensures effective implementation of
safety-related standards and procedures
