Final answer:
The 'Day of Discovery' is included in the calendar days allocated for the repair of an inoperative item as specified in the MMEL. It marks the beginning of the repair period, and calendar days include all consecutive days following the discovery. The specific rules can vary by jurisdiction and airline policy.
Step-by-step explanation:
When a student asks whether the "Day of Discovery" is included in the calendar days or flight days specified in the MMEL (Minimum Equipment List) for the repair of an inoperative item of equipment, they are inquiring about maintenance protocols and aviation regulations that apply to aircraft operations. In this context, the MMEL is a document approved by aviation regulatory bodies, such as the Federal Aviation Administration (FAA), that specifies which pieces of an aircraft's equipment can be inoperative while still allowing the aircraft to operate safely under certain conditions for a specified period.
The "Day of Discovery" refers to when a discrepancy or inoperative item is first identified. According to FAA regulations and guidelines, this day is considered the first of the calendar days allocated for repair or replacement of the inoperative item. This means that if an MMEL stipulates that a particular item must be repaired within 10 calendar days, the count starts on the day the issue is discovered. However, the definition and application of the 'Day of Discovery' can vary by country and specific airline policies, so consulting the applicable MMEL and airworthiness authorities is essential.
