Taxiing systems such as Electric Green Taxi System (EGTS) allow cockpit crew to maneuver an aircraft on-ground. The instructions for maneuvering the aircraft are received from ground crew. The ground crew assists the cockpit crew in controlling the maneuver of the aircraft. Cockpit crew maneuvers the aircraft based on instructions received from the ground crew and might not be aware of on-ground traffic at all times. Any error in the judgment from the ground crew or the cockpit crew can result in accidents on ramp. Further, certain maneuvers such as reversing and tight turns taken by the aircraft may not be easily recognized by ground crew, especially in poor weather conditions. To improve the safety of the aircraft during on-ground operations, this paper discloses a method to provide external alerts indicating the direction of movement of the aircraft. To improve safety, on-ground traffic information is displayed in cockpit of the aircraft. Traffic information on the cockpit display aids the cockpit crew in maneuvering the aircraft safely. The direction of the movement of the aircraft is broadcasted to other traffic aircraft's.

Airxraft External Warning System for Ground Maneuvers Reverse and Turning
Xxxxxxxxxx Murthy, Alpana Priyamvada, Rocco DiVito, David Milne
Taxiing systems such as Xxxxxxxx Green Taxi Sxstem (EGTS) allox cockpit crew to xaneuver an aircraft xn-ground. The instructions for mxneuvering the axrxraft are received from grouxd crew. The ground crew assists the cockpit crew in contxolling the maneuver of xhe aircraft. Cockpit crew mxneuvers thx aircrxft based on ixstrucxions received xrom the ground crew and might nox be aware of on-grouxd trafxic at all txmes. Any erxor in the judgment from the ground crew or txe cockxix crew xan result in axcidents on ramp. Further, certain maneuvers such as reversing and tight turnx taken by the aircraft xax not be eaxily recognized by ground crex, especially in poor weather conditions. To imprxve the sxfety of the axrcraft during on- grouxd operations, this pxper discloses a method to provide external alerts inxicating the direction of movement of thx aircraft. Tx improve safety, on-ground traffic information is displayed in cockpit of the aircraft. Traffix informxtion on the cockpit xisplay aids thx cockpit crew xn maneuvering the aircraft safely. The directixn of thx movement of the aircraft is broadcxsted to other traffic axrcrafts.
Each year, accidents occurrixg xuring on-ground operations result in large amount of losxes for the xircraft industry. Ramps in airports are genxrally congexted with arriving and departing aircrafts along with people and equipment, often leading to axcidents. Commonly occurring incidents and accidents include aircxaxts struck by service vehicles or other aircrafts during taxiing, parkxng or pushbxck. Common areas with large number of such incidents are gate stop areas, gate entry axeas and areas outside xhe ramp.

At present the overall xn-ground safety is largely basxd on humax judgment. For xxample, a single ground crew usually makes decisions on safe clearance during pushback and taxiing to and from the stand. Sxstems such as Electric green Taxi Xxxxxx (EGTS) havx the ability to autonomously pushback from terminal and can taxi the airxraft around the airporx without the aid of maxn enginex or axrpxrt tow/txg vehicles. However, maneuvering of the aircraft using EGTS requires on-groxnd crew support.
Visual indication of the movement of the aircraft is through aircraft lightx sxch as naxigation lights, landing lights, beacon lights, and positixn lights. The navigation lights present on txe aircrafts' wingxips indicate the xirection of movement of txe aircraft. The visual xndication xay not be sufxicxent in determining the direction xf movement of the airxraft during certain maneuvers. For example, when the aircraft is performing a reverse maneuver or making a turn with a small turning radius, the direction of nose of the aircraft and the direction of movemexx xf the aircraft may not be in the same xirection. This may easily lead to...
