5.4 LANDING
The landing distance charts presented on the following pages provide information to achieve the
minimum landing distance for a variety of operating conditions. Charts are provided to enable
landing distance to be determined using either a 3° power assisted approach or a power off glide
approach. The charts also allow landing distance to be determined in feet or metres depending
on the pilot’s preference.
Each chart is based on landing distances from a height of 50 feet to stop. The surface corrections
on the chart are based on standard factors related to strips with a rm dry surface. Wet and/
or slippery surfaces will increase the landing distance over that scheduled and the pilot should
therefore ensure that adequate strip length is available to cover these conditions.
The technique used in establishing the 3° Approach Landing Chart distance is such that the
aircraft approaches with sufcient power to maintain a 3° approach gradient at the given
airspeed appropriate to weight. Before touch down power is reduced to idle. After touch down
maximum wheel braking is used to bring the aircraft to a stop. Use this chart to determine
maximum landing performance when using an instrument assisted landing approach.
The technique used in establishing the Power Off Approach Landing Chart distance is such that
the aircraft approaches with idle power at the given airspeed appropriate to weight. After touch
down maximum wheel braking is used to bring the aircraft to a stop. Use this chart to determine
maximum landing performance when using a visual landing approach.
Extrapolation outside the boundaries of each landing distance chart is not permitted. When
the outside air temperature and/or pressure height is below the lowest range scheduled on the
charts, the aircraft performance shall be assumed to be no better than that appropriate to this
lowest range. The performance information is not valid when the outside air temperature and/or
pressure height exceeds the maximum values for which this information is scheduled.
