gradient one engine inoperative required by the regulations is 2.1 % at a speed not exceeding 1.4
Vs. This requirement is also called approach climb performance by regulations.
The following pages allow to determine the go around limiting weight which satisfies the required
gradient with the certified go around configurations 3 and 2.
The required gradient of 2.1 % is considered at the airport reference altitude. The power setting
is “GO AROUND” thrust with the air conditioning ON. The speed is 1.23 Vs of the specified
configuration. For the occasional cases where approach climb performance is found restrictive, a
correction is given for an increased speed, up to 1.4 Vs.
Note: Landing climb performance (2 engines running) is never limiting.

In the go around configuration corresponding to the all engine procedure, the minimum steady
gradient one engine inoperative required by the regulations is 2.1 % at a speed not exceeding 1.4
Vs. This requirement is also called approach climb performance by regulations.

According to airport pressure altitude and temperature determine if the slats/flaps setting must be
restricted as a function of the landing weight, in order to meet the go around gradient requirement of
2.1 %.
Establish the final approach configuration with one more step of flaps. If the approach is interrupted,
retract the flaps by one step during the go-around.

In case of category II approach, JAR-OPS requires a regulatory approach climb gradient of 2.5 % to
be maintained.
Use the tables for CAT II approach to determine the maximum approach climb limiting weight
according to airport pressure altitude and temperature.
Note: 1. If circumstances dictate, landing may be made at a weight corresponding to the
maximum structural takeoff weight. (Refer to STLO-ABN-80 OVERWEIGHT LANDING).
2. When icing conditions are predicted during the flight and TAT is 10 °C or below and there
is an evidence of significant ice accretion, to take into account ice formation on the non
heated structure :
decrease the approach ‐ climb limiting weight by 4.5 %.
‐ in CONF FULL, the approach speed must not be lower than VREF +5 kt and the
landing distance must be multiplied by 1.1.
or
in CONF 3, the approach speed must not be lower than VLS +10 kt and the landing
distance must be multiplied by 1.15.
3. In the following tables corrections for anti ice are only valid for OAT lower than 10 °C.
