Introduction

This document defines a series of standard callout for use in the operation of simple
single engine general aviation aircraft, for example Cessna 172 and Cessna 172RG. B
necessity these callouts are generic in nature and may need to be customized for
individual aircraft, pilots and checklists.
Callouts are generally found in structured environments and in multiple crew cockpits.
The use of standard callouts is a best practice that can be applied to all environments and
to single and multiple pilot operations. The use of callouts during instructional flights is
also useful, although pilots are encouraged to standardize on the use of callouts or not,
and not to switch between operational practices depending on the nature of the flight.
Document Conventions
This document consists of a series of actions or events that initiate a callout and the
callout itself in quotation marks.
Use of Checklists
This document does not cover the use of checklists, do-lists or flow checks. See other
documents in the series for this information. The verbalized challenge and response use
of checklists dovetails neatly into the decision to use callouts.
In this document a number of callouts start and end the use of a specific checklist. Not all
aircraft checklists are arranged in the same way, and often pilots use customized
checklists that further widen the range of options available. This is one area in which
pilots may need to customize the use of callouts.
Items in italics should be replaced with the appropriate indication – for example “Flaps
XX” would become “Flaps 10”.
In some cases the optional plural is used – for example “Green Light(s)”. This depends
on the aircraft indications. In some aircraft a more appropriate callout might be “3
Greens”.
Normal Callouts
Normal callouts are used in the course of normal operations. We differentiate them from
Emergency and Abnormal callouts as well as a separate set of callout associated with IFR
operations. IFR operations would include the normal callouts in addition to the IFR
callouts.
