After engine start and before takeoff, illumination of a red warning light, an amber
caution light, an alert or other indication requires completion of the associated
checklist. In certain cases, amber caution lights illuminate during MASTER
CAUTION recall to inform the flight crew of the failure of one element in a
system with redundant elements. If system operation is maintained by a second
element, the amber caution light will extinguish when MASTER CAUTION is
reset. In these situations, the amber caution light alerts the flight crew that normal
system operation will be affected if another element fails. If an amber caution light
illuminates during MASTER CAUTION recall, but extinguishes after MASTER
CAUTION reset, completion of the associated checklist is not required.
Non–Normal Checklist Use
If a checklist or a step in a checklist is not applicable to all airplanes, airplane
effectivity information is included in the checklist. Airplane effectivity can be
listed by airplane number, registry number, serial number or tabulation number. If
a checklist is applicable to some but not all airplanes, airplane effectivity is
centered below the checklist title. If a step in a checklist is applicable to some but
not all airplanes, airplane effectivity is included above the step. If a checklist or a
step in a checklist is applicable to all airplanes, airplane effectivity information is
not included.
Non–normal checklist use starts when the airplane flight path and configuration
are correctly established. Only a few situations need an immediate response (such
as CABIN ALTITUDE WARNING or Rapid Depressurization). Usually, time is
available to assess the situation before corrective action is started. All actions must
then be coordinated under the captain's supervision and done in a deliberate,
systematic manner. Flight path control must never be compromised.
When a non–normal situation occurs, at the direction of the pilot flying, both
crewmembers do all memory items in their areas of responsibility without delay.
The pilot flying calls for the checklist when:
• the flight path is under control
• the airplane is not in a critical phase of flight (such as takeoff or landing)
• all memory items are complete.
The pilot monitoring reads aloud:
• the checklist title
• the airplane effectivity (if applicable) as needed to verify the correct
checklist.
• as much of the condition statement as needed to verify that the correct
checklist has been selected
• as much of the objective statement (if applicable) as needed to
understand the expected result of doing the checklist.
