Standard calls are used to:
.  
Give a command (task delegation) or transfer an information;

.  
Acknowledge a command or an information transfer;

.  
Give a response or ask a question (feedback);

.  
Callout a change of indication (e.g., a mode transition or reversion); or,

.  
Identify a specific event (e.g., crossing an altitude or a flight level).

Defining Generic Standard Calls
The following generic standard calls often are used to express a command or response:
.  Check ( or Verify ):
- a command for the other pilot to check an item;

.  Checked:
-a confirmation that an item has been checked;

.  Cross-check(ed):
- a call (response) confirming that an information has been checked at both pilot stations;

.  Set:
-a command for the other pilot to set a target value or a configuration;

.  Arm:
- a command for the other pilot to arm an AP/FD mode (or to arm a system);

.  Engage:
- a command for the other pilot to engage an AP/FD mode (or to engage a system);

.  ON / OFF:
-ON or OFF following the name of a system is either:
.. a command for the other pilot to select / deselect the related system; or,
.. a response confirming the status of the system.

Specific Standard Calls
Appropriate standard calls should be defined for the following events:
.  
Flightcrew/ground mechanics communications;

.  
Engine start sequence;

.  
Specific event-markers along the takeoff phase;

.  
Landing gear and slats/flaps selection (retraction or extension);

.  
Initiation, interruption, resumption and completion of normal checklists;

.  
Initiation, sequencing, interruption, resumption and completion of abnormal and emergency checklists (paper or electronic checklist);

.  
Mode transitions and reversions (i.e., FMA changes);

.  
Changing the altimeter setting;

.  
Approaching the cleared altitude or FL;

.  
TCAS / TA or RA events;

.  
PF/PNF transfer of controls;

.  
Excessive -deviation of a flight parameter;

.  
Specific points along the instrument approach procedure;

.  
Approaching and reaching minimums;

.  
Acquisition of visual references; and,

.  
Landing or go-around decision.

Use of standard calls is of paramount importance for optimum use of automation (i.e., for awareness of arming or engagement of modes by calling FMA changes, target selections, FMS entries, …):
.  The standard calls should trigger immediately the question “ what do I want to fly now ? “, and thus clearly indicates which:
- mode the pilot wishes to arm or engage; and/or,
-target the pilot wishes to set.
When the pilot’s (PF) intention is clearly transmitted to the other pilot (PNF), the standard call will also:
-facilitate the cross-check of the FMA and PFD/ND, as applicable; and,
-facilitate the cross-check and backup between both pilots.
Standard calls should be defined for cockpit crew / cabin crew communications in both:
.  
Normal conditions (departure and arrival); and,
