Regulations Governing Aircraft Takeoff and Landing Quota in Domestic Airports Article 9

The CAA may provide unused airport quota of an enterprise to another enterprise on a temporary basis if and when the runway needs an overhaul or any other emergency arises.The enterprise may apply, to CAA, for additional airport quota, which is unused and available for a short term period, in order to meet a temporary market demand if its original allocated airport quota is insufficient, however, the additional airport quota shall not be used for more than six months during the whole year.If any allocated airport quota is used on an air route that apparently has a peak season and a low season, and the average rate of its usage does not reach seventy percent (70%) for six consecutive months, the CAA may then retract the unused portion thereof.In addition to an air route mentioned in the preceding paragraph, the CAA may also retract the unused portion of any airport quota whose average rate of usage does not reach eighty percent (80%) for six consecutive months.Any unused portion of the airport quota that is not attributable to an enterprise will not be considered when calculating the rate of usage mentioned in the preceding two paragraphs.The air route that apparently has a peak season and a low season as mentioned in Paragraph 3 hereof means one whose highest monthly average passenger capacity for three consecutive months during the past year is one and half times that of the lowest monthly average passenger capacity during the same period.In the event that an enterprise terminates any of its domestic scheduled air routes, the CAA may retract its original allocated airport quota, wherein, such retracted airport quota thereto will be calculated based on the average quota of its usage of such air route in a period of six consecutive months prior to the actual termination month.
中文原文 國內機場航空器起降額度管理辦法第9條
民航局因跑道整修或其他緊急需要,得將業者未使用之機場額度,暫時提供其他業者使用。
業者因市場臨時性需求,原分配之機場額度不敷使用時,得向民航局申請核准短期使用未分配之機場額度,但全年使用期間不得逾六個月。
經分配用於具顯著淡、旺季特性航線之機場額度,其連續六個月機場額度平均使用率未達百分之七十時,民航局得收回未使用之額度。
除前項航線外,經分配之機場額度,連續六個月平均使用率未達百分之八十時,民航局得收回未使用之額度。
因不可歸責於業者之因素,致未使用之機場額度,不列入前二項使用率之計算。
第三項所稱具顯著淡、旺季特性航線,係指前一年連續三個月之最大平均月載客量為最小平均月載客量之一點五倍以上之航線。
業者終止國內定期航線時,民航局得收回原分配予業者之機場額度,其數量依該航線終止當月之前六個月平均使用機場額度數計。
