Visual Approach Indicators are visual aids used in aviation to assist pilots during the landing phase of flight. These indicators help pilots align their aircraft with the runway and provide essential information about altitude, distance, and approach angle. Common examples include PAPI (Precision Approach Path Indicator) lights, which indicate whether the aircraft is on the correct glide slope. These indicators enhance safety by allowing pilots to make real-time adjustments to their approach. They are especially useful in low-visibility conditions, where traditional navigation aids may be less effective. Overall, Visual Approach Indicators play a crucial role in ensuring safe landings at airports.
