CAT.POL.A.225 Landing – destination and alternate aerodromes

ALTITUDE MEASURING The operator should use either pressure altitude or geometric altitude for its operation and this should be reflected in the operations manual.

MISSED APPROACH

(a)For instrument approaches with a missed approach climb gradient greater than 2.5 %, the operator should verify that the expected landing mass of the aeroplane allows for a missed approach with a climb gradient equal to or greater than the applicable missed approach gradient in the OEI missed approach configuration and at the associated speed.

(b)For instrument approaches with DH below 200 ft, the operator should verify that the expected landing mass of the aeroplane allows a missed approach gradient of climb, with the critical engine failed and with the speed and configuration used for a missed approach of at least 2.5 %, or the published gradient, whichever is greater.

MISSED APPROACH GRADIENT

(a)Where an aeroplane cannot achieve the missed approach gradient specified in AMC2 CAT.POL.A.225, when operating at or near maximum certificated landing mass and in engine-out conditions, the operator has the opportunity to propose an alternative means of compliance to the competent authority demonstrating that a missed approach can be executed safely taking into account appropriate mitigating measures.

(b)The proposal for an alternative means of compliance may involve the following:

(1)considerations to mass, altitude and temperature limitations and wind for the missed approach;

(2)a proposal to increase the DA/H or MDA/H; and

(3)a contingency procedure ensuring a safe route and avoiding obstacles.
