AAAE ACE Operations Module 2
(2022/2023) (Verified Answers)
What are the two major categories of pavement? ✔✔Flexible and rigid
What are some types of flexible pavement? ✔✔Grass, dirt, gravel and 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
Airport surfaces are distinguished by operational control and FAA design standards into what
two areas? ✔✔Movement and non-movement
What constitutes the movement area on an airport? ✔✔Runways and taxiways. At ATCT
controlled airports, the surfaces under ATC control. These areas must meet Part 139 design
restrictions.
What constitutes the non-movement area of an airport? ✔✔Taxiways and aprons not under
ATCT control
,How are movement and non-movement areas determined at an airport with an ATCT? ✔✔By
Letter of Agreement (LOA) between the airport and the ATCT.
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)
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
Edges of abutting pavement or pavement and other areas must be no more than how many inches
in elevation difference? ✔✔3 inches
What are the maximum dimensions of a hole that are allowed by Part 139? ✔✔Any hole with a
diameter greater than 5 inches and either 3 inches deep or a slope of greater than 45 degrees
How far are landing distances increased on wet pavement? ✔✔By 15 percent or more
What are the three types of hydroplaning? ✔✔Dynamic, viscous, and rubber reversion
What are three pavement elements that help to mitigate hydroplaning? ✔✔pavement grooving,
porous friction course, wire combing
