,What are the two major categories of pavement? - ANS Flexible and rigid
What are some types of flexible pavement? - ANS Grass, dirt, gravel and asphalt
Why are paved surfaces necessary at airports? - ANS To support the critical loads imposed
A
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? - ANS It
R
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.
U
What are two major elements that make pavements deteriorate? - ANS
aircraft loads
weathering and
LA
For bearing strengths of 12,500lbs or greater, what method is used to express the effect of an
individual aircraft on different pavements? - ANS 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? - ANS
PCN is the maximum pavement bearing strength for unrestricted aircraft operations.
C
What is the Load Classification Number (LCN) used to describe? - ANS Pavement bearing
strengths less than 12,500lbs
O
What are the five major categories of pavement distress? - ANS cracking, joint seal
damage, disintegration, distortion, loss of skid resistance
D
How far are landing distances increased on wet pavement? - ANS By 15 percent or more
Where are wind cones located? - ANS 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? - ANS daily; when
required by an unusual condition; immediately after an accident or incident
,How long must airfield self-inspection records be kept? - ANS 12 consecutive calendar
months
How often must operations personnel be trained on self-inspection related activities and how
long must training records be kept? - ANS training every 12 consecutive calendar months,
records maintained for 24 months
How long must a record of airfield condition NOTAMs be kept? - ANS 12 months
What are four types of inspections? - ANS Regular scheduled; continuous surveillance;
periodic; special
A
How is safety oversight defined? - ANS those means and activities by which airport
management ensures effective implementation of safety-related standards and procedures
R
Why does an airport need a Safety Management System? - ANS to increase the likelihood
that airport operators will detect and correct safety problems before those problems result in an
aircraft incident.
U
In November 2005, the International Civil Aviation Organization (ICAO) required what? - ANS
Required certificated international airports to establish an SMS
LA
What are the four pillars of the Safety Management System? - ANS policy/objectives, risk
management, assurance, and promotion
What are four key elements of airport safety policy and objectives? - ANS Safety program
methods, processes, authorities and accountability
C
What are the five phases of the safety risk management process? - ANS Phase 1: describe
the system; Phase 2: identify the hazard; Phase 3: determine the risk; Phase 4: assess and
analyze the risk; Phase 5: treat the risk
O
What four items enhance an airport's ability to identify hazards? - ANS operational
expertise; training in hazard analysis techniques; use of a hazard analysis tool; documenting the
D
process
What are four risk mitigation strategies? - ANS avoidance (stop or shift the operation),
assumption (accepting the risk), control (minimize or eliminate the risk), transfer (shift risk to
another area)
What are four types of risks taken by airport operators? - ANS Informed, uninformed,
benefit-driven, pointless
What does safety assurance include? - ANS auditing and oversight
, What does safety promotion involve? - ANS training, education, communication and
continuous improvement
What are a few communication methods that may be effective for a safety program? - ANS
seminars, bulletins or notices, lessons-learned, and cross-tell
