equipment, the most appropriate level of automation 
and visual cues should be used to achieve and 
monitor the stabilization of the aircraft. 
When breaking-out of the cloud overcast and 
transitioning to visual references, the pilot’s 
perception of the runway and outside environment 
should be kept constant by maintaining the: 
. Drift correction, to continue tracking 
the runway centerline, resisting the tendency to 
prematurely align the aircraft with the runway 
centerline; 
. Aiming point (i.e., the touchdown zone), 
to remain on the correct flight path until flare 
height, resisting the tendency to move the aiming 
point closer and, thus, descend below the 
desired glide path (i.e., “duck-under”); and, 
. Final approach speed and ground speed, to 
maintain the energy level.

Introduction
Planning and conducting a non-precision approach (NPA) is certainly the most challenging and demanding part of a flight, this includes:
.  
Decision making on strategies and options;

.  
Effective task-sharing;

.  
Crew coordination (monitoring and callouts); and,

.  
CFIT awareness (response to GPWS or EGPWS / TAWS warning).

Various types of NPAs (also called non-ILS approaches) share common features but also involve specific techniques, depending on the navaid being used or on the strategy being adopted for:

.  
Lateral and vertical guidance;

.  
Descending from the final approach fix (FAF) down to the minimum descent altitude(height) MDA(H); and,

.  
Making the decision before or when reaching the MDA(H).

This Briefing Note describes the features common to all types of non-precision approaches and the specific features of each individual type of approach.
This Briefing Note highlights the technique of constant-angle (constant-slope) non-precision approach, as opposed to the traditional step-down technique.
