7. PERFORMANCE
The performance in Chapter 6 is applicable, except as modified by the following:
The data in this supplement are applicable to steep approaches from 4.5 to 5.5 degrees
(inclusive), except for this section, which is applicable only for approaches conducted at
5.5 degrees. For all other approach angles, the performance data in Chapter 6 is applicable.
A. Landing Performance
The reference screen height used for landing is 50 feet.
The reference steep approach glide slope angle is 5.5 degrees.
(1) LANDING FIELD LENGTH AND SPEED
The landing field length required for 5.5 degree approach operations for varying
conditions of airplane landing weight, airport pressure altitude and wind is provided by
Figure 07−12−1. The actual landing distance required is also given within this chart.
The landing approach speed (VREF) for varying airplane landing weights and airport
pressure altitude for steep approach operations is also given by Figure 07−12−1.
The actual landing distance given on Figure 07−12−1 is the distance from a 50 foot
height at VREF with flaps 45°, to a full stop on a smooth, dry, level, hard-surfaced runway
and ISA temperature for steep approach operations.
NOTE
1. The landing field length derived from Figure 07−12−1 includes
factors for operational rules which require use of 60% of the
available runway (landing field length required).
2. Operational rules may require that for wet or slippery runway
surfaces, the runway length available be at least 115% of the
landing field length derived from Figure 07−12−1 .
Example:
Associated Conditions:
Landing gross weight = 15,000 kg (33,069 lb)
Airport pressure altitude = 4,000 feet
Wind = 20 knots, headwind
The example in Figure 07−12−1, shows that for the above conditions, the actual landing
distance is 705 meters (2,313 feet) and the landing field length is 1,175 meters
(3,855 feet).
VREF for the same conditions as above is 126 KIAS.

(2) ADDITIONAL LANDING INFORMATION
The distance from the visual glide path system runway position to full stop for varying
conditions of airplane landing weight, airport pressure altitude and wind is provided by
Figure 07−12−2. This is the minimum stopping distance achievable on a dry runway past
the intersection of the approach path and the runway surface. It is derived from an
approach to landing glideslope of 5.5 degrees maintained to a threshold crossing height
of 50 feet, a firm touchdown and maximum braking.
This distance is provided to cater for runway variability in position of the visual glide path
systems and threshold crossing heights.
The most limiting distance from Figure 07−12−1 or Figure 07−12−2 is to be used.
Example:
Associated Conditions:
Landing gross weight = 15,000 kg (33,069 lb)
Airport pressure altitude = 4,000 feet
Wind = 20 knots, headwind
The example in Figure 07−12−2, shows that for the above conditions, the distance from
glide path system position to full stop is 540 meters (1,772 feet).
