“…Because the existence of aircrafts holding is critical for cooperation, we further give some statistical data of stack holding in airports. It was investigated in summer, 2005, almost 60 aircrafts have spent more than 15 min in the holding stack each day in Hartsfield-Jackson Atlanta International Airport, which are mainly caused by rain [22]. In the summer of 2007, it was observed in Newark airport that the holding time spent for all arrival aircrafts is almost 15 000 min, and in 55% holding time, there exists more than two aircrafts in the holding stack [23].…”

The ground-to-air communications in the aircraft approach stage suffer from multipath fading. We propose to combat this problem using cooperative communication technique. The relay selection problem is formulated to minimize the spectrum cost while preserving the signal-to-noise-ratio (SNR) outage requirement of the approaching aircraft. By leveraging the position and velocity information in the automatic dependent surveillance-broadcast messages, the average channel gains can be derived with uncertainty sets based on the Ricean channel model. Because the outage probability of the received SNR is intractable, we transform the outage constraint into a simple but efficient reliability requirement. The formulated problem is a mixed integer nonlinear optimization problem, with robustness in the worst-case average SNR. A robust greedy relay selection algorithm is proposed as a solution, whereby a Kalman filter based trace prediction algorithm is adopted to determine the order of relays. Simulation results are given to show the effectiveness of the proposed scheme. -B of the aircraft under serious weather condition, the synthetic vision system (SVS) [2] has been developed to extend the visual range of the pilot. The SVS can integrate the position information from global positioning system and inertial navigation system with the traffic information from the control tower, which are displayed on the screen to help the pilot make decisions. In SVS, data link technology is adopted for the signal transmission from the control tower to the approaching aircraft. However, because of the high speed and low elevation of the approaching aircraft, the performance of point-to-point data link suffers from serious multipath fading in the flight test [3,4].In the last decade, cooperative communication technique has received much attention in the communication society [5][6][7], which is proved to be effective in combating multipath fading by exploiting the spatial diversity of the relay nodes. In our work, we consider the application of cooperative communication technique in the aircraft approach scenario. Considering the requirement RELAY SELECTION FOR COOPERATIVE COMMUNICATIONS IN AIRCRAFT APPROACH 115 ‡ Straight-in approach means the final approach has begun without first executing a procedure turn, and the trace of the aircraft approach follows the extended runway centerline. In fact, the approaching pattern only determines the mobility pattern of the aircrafts. The analysis and algorithm in our paper still work under other approaching patterns. § The simulation is conducted on MATLAB 7.0.1, where the system configurations are : Intel(R) Core(TM)2 Duo CPU E7200@2.53GHz, 2G RAM, 32bit OS.

“…Track data from the Enhanced Traffic Management System (ETMS) for June 2007 was analyzed by a hold detection algorithm [2] to find the aircraft that were held prior to arriving at these airports. The algorithm determines the position of the hold at the starting time of the hold, the ending time of the hold and the distance traveled in the hold.…”

Holding in the National Airspace System (NAS) is a necessity in the management of air traffic into the major airports in the system. The necessity follows from the desire not to waste any landing slots at the airport in the face of system uncertainties. Holding patterns maintain a ready reservoir of aircraft nearby the airport to provide a steady flow of aircraft. At the same time that this strategy provides an effective mechanism for providing pressure on the airport, it is workload intensive and inefficient in flowing aircraft uniformly to the airport.This document provides evidence of the amount of holding that is experienced for the New York airports and introduces a concept of using Automatic Dependent Surveillance -Broadcast (ADS-B) information to reduce the controller workload and increase the uniformity of the flow of aircraft out of the holding patterns. Estimates of the expected benefits are also presented as well as the next steps to be taken.
