What type of navigation aids do helicopters primarily use?

The correct answer is GPS and VOR (VHF Omnidirectional Range) navigation aids, which are essential for helicopter navigation. GPS provides precise positioning, allowing pilots to determine their exact location anywhere on Earth. It is especially important in navigation, as it enables route planning and real-time updates on the helicopter's position, crucial for safe operations, particularly in low visibility conditions.

VOR, on the other hand, is a type of radio navigation system that helps pilots determine their position relative to the navigation aid. VOR stations transmit signals that allow pilots to use their aircraft's navigation equipment to navigate along specific radial courses leading to or from the station. This reliability makes VOR a practical tool for helicopters, especially when flying within controlled airspace or near airports.

In contrast, while GPS and radar systems can be utilized together for enhanced navigation and situational awareness, radar is typically more relevant in air traffic control and surveillance than for helicopter navigation itself. Inertial navigation systems (INS) are sophisticated technologies that can be used, but they are less common in helicopters compared to GPS and VOR due to complexity and cost. Satellite communication systems are vital for maintaining contact and relaying information but do not directly assist in navigation. Thus, the combination of GPS
