CAT.OP.MPA.303 In-flight check of the landing distance at time of arrival - aeroplanes

  1. No approach to land shall be continued unless the landing distance available (LDA) on the intended runway is at least 115% of the landing distance at the estimated time of landing, determined in accordance with the performance information for the assessment of the landing distance at time of arrival (LDTA) and the approach to land is performed with performance class A aeroplanes that are certified in accordance with either of the following certification specifications, as indicated in the type-certificate:

    1. CS-25 or equivalent;

    2. CS-23 at level 4 with performance level “High speed” or equivalent.

  2. For performance class A aeroplanes other than those referred to in point (a), no approach to land shall be continued, except where:

    1. the LDA on the intended runway is at least 115% of the landing distance at the estimated time of landing, determined in accordance with the performance information for the assessment of the LDTA; or

    2. if performance information for the assessment of the LDTA is not available, the LDA on the intended runway at the estimated time of landing is at least the required landing distance determined in accordance with point CAT.POL.A.230 or point CAT.POL.A.235, as applicable.

  3. For performance class B aeroplanes, no approach to land shall be continued, except in either of the following situations:

    1. the LDA on the intended runway is at least 115% of the landing distance at the estimated time of landing, determined in accordance with the performance information for the assessment of the LDTA; or

    2. if performance information for the assessment of the LDTA is not available, the LDA on the intended runway at the estimated time of landing is at least the required landing distance determined in accordance with point CAT.POL.A.330 or point CAT.POL.A.335, as applicable.

  4. For performance class C aeroplanes, no approach to land shall be continued, except in either of the following situations:

    1. the LDA on the intended runway is at least 115% of the landing distance at the estimated time of landing, determined in accordance with the performance information for the assessment of the LDTA; or

    2. if performance information for the assessment of the LDTA is not available, the LDA on the intended runway at the estimated time of landing is at least the required landing distance determined in accordance with point CAT.POL.A.430 or point CAT.POL.A.435, as applicable.

  5. Performance information for the assessment of the LDTA shall be based on approved data contained in the AFM. When approved data contained in the AFM are insufficient in respect of the assessment of the LDTA, they shall be supplemented with other data which are either determined in accordance with the applicable certification standards for aeroplanes or determined in line with the AMCs issued by the CAA.

  6. The operator shall specify in the OM the performance information for the assessment of the LDTA and the assumptions made for its development, including other data that, in accordance with point (e), may be used to supplement that contained in the AFM.
