Final answer:
A 705 aircraft can fly beyond 60-minute one-engine inoperative range from a suitable alternate if it meets specific safety requirements and regulations. Historical aviation incidents demonstrate the critical nature of proper unit conversion and regulation compliance for flight safety. Specific clearances such as ETOPS allow operations outside of standard alternate airport requirements.
Step-by-step explanation:
A 705 aircraft may fly on a route with a point that is further than the distance that can be flown in 60 minutes at a one-engine inoperative cruise speed to a suitable alternate and not within the Canadian Domestic Airspace if applicable regulations and exemptions allow it. In certain cases, such as over oceans or uninhabited areas, alternate airport requirements may be relaxed or not applicable, provided specific safety measures and equipment are in place, such as ETOPS (Extended-range Twin-engine Operational Performance Standards) which dictate the maximum allowed flight time on one engine to the nearest suitable airport for twin-engine aeroplanes flying on certain routes.
Historical incidents like the emergency landing of an Air Canada Boeing 767 due to fuel miscalculation highlight the importance of accurate measurements and adherence to regulations for the safety of both crew and passengers. This error was a result of failing to properly convert between the metric system and the English unit system. Similarly, maintaining safe distances between aircraft, as regulated by the Federal Aviation Administration, ensures that planes avoid mid-air collisions.
Therefore, while standard regulations require proximity to suitable alternates, 705 aircraft may operate beyond these limits when additional criteria are satisfied and with proper authority clearance. This relates to multifaceted safety and regulatory procedures ensuring aircraft can divert and land safely in unexpected circumstances.
