Abstract

Awareness of the runway conditions is a key parameter in safe landing of an aircraft. Real time information of runway conditions at decision height (DH) is critical in enabling pilots to make a decision on touching down or aborting landing. A high resolution infrared camera fitted in the nose of an aircraft can be used to capture runway visibility conditions at various strategic altitudes starting from initial approach to touchdown. These images are transmitted to the next aircraft queued up for landing using high bandwidth connectivity. This approach ensures awareness of runway conditions for the pilot of the aircraft even before reaching the decision height. Such advanced awareness helps pilot in avoiding go around decision made too close to the terminal thus enhancing the economy and safety of air traffic management.

1. Introduction

The runway visibility and awareness of the runway conditions during final approach phase is a key for safe landing. There are many situations that could make aircraft landing potentially unsafe. Debris or foreign objects may occur on runways, which can be due to jet blast, aircraft take-off/landing, natural causes etc. Certain weather conditions such as clouds, rain, fog, smoke, snow decrease the visibility or completely prevent the pilot of the aircraft from visualizing the runway and to monitor the aircraft's approach along the landing glide path. With the increase in global air traffic, aircrafts are often queued up for landing while airport authorities are under tremendous pressure to ensure that the runways are safe and utilized to their maximum potential.

related accidents, e.g., due to airport runway congestion and Foreign Object Debris (FOD), are more likely to occur with more aircrafts on runways.

Most existing approaches to monitor runways rely on means of capturing runway conditions using one or more imaging devices located near the runway and sharing the images with key stakeholders (airline crews, ATC, etc.) to aid in safe landing of aircraft.

One type of aircraft landing system uses a radar system having scanning antennas located near the runway that scan the aircraft approach path in both azimuth and elevation. Reflected radar waves from the aircraft are detected and displayed on a monitor in a control facility in both the elevation and azimuth relative to the desired landing path. From this display, a ground controller instructs the pilot of the aircraft by voice transmissions of the aircraft's position relative to the desired glide path to allow the pilots to adjust the aircraft position for a proper landing.

An instrument landing system (ILS) is another type of known aircraft landing system that include antennas positioned near the runway that radiate localizer and glidepath beams to provide left-ri...
