What is a common characteristic of flight planning software used in helicopters?

The characteristic that the flight planning software for helicopters includes routing and performance data for specific aircraft highlights its tailored functionality for safe and effective flight operations. This software is designed to meet the various needs of helicopter pilots, offering them specific information on the aircraft’s performance capabilities, which are critical for planning flight routes that account for factors such as weight, fuel efficiency, altitude capabilities, and airspace restrictions.

Routing data provides pilots with the necessary information to plot safe and efficient courses, while performance data ensures that these routes are appropriate for the specific helicopter being used. This enhances situational awareness and allows pilots to make informed decisions in real-time.

While weather information is an important feature of such software, it is not the only function and therefore doesn't encompass the full utility of the tool. Additionally, the software is specifically designed for helicopters rather than commercial jetliners, which have different requirements and flight planning needs. Lastly, while it can assist with navigation, it is not merely a backup system; it plays an integral role in flight planning from the outset, ensuring that all aspects of the flight are well-coordinated.
