The actual landing distance required is obtained by reference to the IFLD data supplied by the manufacturer either through an approved EFB or the aircraft’s Operations Manual.\n\n2 Despite subsection 11 of CAO 20.7.1B, when in-flight, except in an emergency, pilots employed by the operator must use a landing distance that is 1.15 times the IFLD.","sortOrder":0}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2983},"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"The instrument maintained its original narrow scope as a temporary, operator-specific direction providing an alternative compliance method for calculating landing distances.
