What is the maximum speed of an air-taxi operation according to the specified parameters?

In air-taxi operations, the defined parameters typically set constraints on the maximum speed to ensure safety, efficiency, and compliance with regulatory guidelines. The correct answer is the highest speed listed, which is 100 knots. This speed allows for a balance between safe maneuverability and operational capability of the aircraft within urban environments or busy airspaces where these operations are common.

Air-taxi services are designed to provide convenient, rapid transportation in urban areas, and a maximum speed of 100 knots facilitates effective service while adhering to flight safety protocols. It also takes into account the performance capabilities of many aircraft that might be used in these operations, ensuring that they can operate safely and efficiently within such parameters without the risk of exceeding operational limits.

Lower speeds specified in the other choices do not align with the operational needs of many air-taxi flights, which aim to minimize travel time while still operating within controlled airspace. Thus, the maximum speed set at 100 knots accommodates the need for swift transportation while still remaining within safe operational boundaries.
