Adaptive flight control is a potentially promising technology that can improve aircraft stability and maneuverability. In recent years, adaptive control has been receiving a significant amount of attention. In aerospace applications, adaptive control has been demonstrated in many flight vehicles. For example, NASA has conducted a flight test of a neural net intelligent flight control system on ...

Optimal scheduling of airport runway operations can play an important role in improving the safety and efficiency of the National Airspace System (NAS). Methods that compute the optimal landing sequence and landing times of aircraft, while delivering high quality solutions, must accommodate practical issues that affect the implementation of the schedule. One such practical consideration, known ...

This paper addresses the real-time problem of coordinating aircraft ground and air operations in an airport area. At a congested airport, airborne decisions are related to take-o↵ and landing operations, while ground (taxiway) decisions consist of scheduling aircraft movements between the gates and the runways. Since the runways are the initial/terminal points of both decisions, coordinated act...

This paper presents a polynomial time algorithm used for solving a Mixed Integer Linear Program (MILP) formulation of a scheduling problem applicable to Air Traffic Control. We first relate the general MILP (which we believe to be NP-Hard) to the Air Traffic Control problem, which consists of performing maneuver assignments to achieve scheduling constraints for airport arrival traffic. This MIL...

We address a scheduling problem in the context of military aircraft maintenance where the goal is to meet the aircraft requirements for a number of missions in the presence of breakdowns. The assignment of aircraft to a mission must consider the requirements for the mission, the probability of aircraft failure, and capacity of the repair shop that maintains the aircraft. Therefore, a solution b...

Airline disruptions incurred huge cost for airlines and serious inconvenience for travelers. In this paper, we study the integrated aircraft and crew schedule recovery problem. A two stage heuristic algorithm for the integrated recovery problem is proposed. In the first stage, the integrated aircraft recovery and flight-rescheduling model with partial crew consideration is built. This model is ...

The airline industry has a long history of developing and applying optimization approaches to their myriad of scheduling problems, including designing flight schedules that maximize profitability while satisfying rules related to aircraft maintenance; generating cost-minimizing, feasible work schedules for pilots and flight attendants; and identifying implementable, lowcost changes to aircraft ...

-This paper describes the design, development and results from a high fidelity human-in-the-loop simulation of an integrated set of trajectory-based automation tools providing precision scheduling, sequencing and controller merging and spacing functions. These integrated functions are combined into a system called the Terminal Area Precision Scheduling and Spacing (TAPSS) system. It is a strate...

The dynamic response characteristics of modern aircraft vary substantially with ight conditions. These changes require scheduling of the ight control system with variables such as dynamic pressure and Mach number. This scheduling can be accomplished easily for simple controllers but is much more diicult for complex controllers which result from the use of most modern control design techniques. ...

The capacity of a runway system represents a bottleneck at many international airports. The current practice at airports is to land approaching aircraft on a first-come, first-served basis. An active rescheduling of aircraft landing times increases runway capacity or reduces delays. The problem of finding an optimal schedule for aircraft landings is referred to as the “aircraft landing problem”...
