Aircraft Operations

III-4-1-2
Procedures — Aircraft Operations — Volume I
1.3 Operators should ensure that flight personnel are aware of the risk factors in the aerodrome surface operations
listed in 1.1. Such risk factors should include, but not be limited to:
a) human error due to excessive workload, loss of vigilance and fatigue;
b) potential distractions associated with the performance of flight deck tasks; and
c) failure to use standard phraseology in aeronautical communications.
Note.— The safety of aerodrome surface operations is especially vulnerable to the failure to use standard
phraseology in aeronautical communications. Frequency congestion, as well as operational considerations, may
adversely affect the issuance and read-back of clearances, leaving flight crews and controllers vulnerable to
misunderstandings.
