For separation of helicopters, which adjustments may be more practical than course changes?

• A. Speed
• B. Altitude
• C. Heading
• D. Vertical separation

Answer: (A)

Speed adjustments are often the simplest way to maintain or restore separation between helicopters without changing their course. Since rotorcraft can alter speed readily, you can create more space by letting one helicopter slow down or allow another to speed up, all while keeping them on the same route. Turning to a new heading would disrupt traffic flow and can introduce conflicts with other aircraft on adjacent tracks. Changing altitude to gain separation may not be feasible due to terrain, airspace structure, or other traffic at different levels, and vertical separation requires an altitude change rather than a straightforward, practical speed adjustment. So, adjusting speed is the most practical method here.
