What is the typical cruise speed of a commercial helicopter?

The typical cruise speed of a commercial helicopter is generally within the range of 120 to 150 knots. This speed is indicative of the performance capabilities of many commercially used helicopters which are designed for a mix of efficiency and versatility in various operational scenarios, including air transport, utility work, and medical evacuations.

Helicopters designed for commercial use often prioritize speed and range, making them capable of maintaining cruise speeds in this bracket. This enables operators to complete missions in a timely manner while still allowing for operational flexibility. A cruise speed of 120 to 150 knots strikes a balance between efficient fuel consumption and the ability to reach destinations swiftly, which is crucial for commercial operations.

In contrast, other ranges listed would either pertain to slower helicopters, often used for training or typical private use, or faster models that may include military or specialized transport helicopters which exceed the speeds listed in the range of 150 knots. Therefore, the option that states 120 to 150 knots accurately reflects the standard operational speed for many commercial helicopters.
