Abstract

With increasing demand for air transportation, the air traffic at airports is increasing exponentially. Initiatives such as NextGen and SESAR are being implemented to allow aircraft to fly close, take direct routes and avoid delays at the airports. Delays associated with aircraft waiting for departure clearances is rising with increasing air traffic. Currently, the controller assigns a departure runway for each aircraft based on aircraft type. At times, the assigned departure runway may be insufficient for the aircraft, as the controller may not be aware of current aircraft load and thrust settings. Communications between cockpit and the controller regarding sufficiency of the assigned runway leads to delay in departure. This leads to increased queue for departure clearances and reduces efficiency of operations. The proposed solution utilizes the connectivity between cockpit and ground systems. An Advanced Surface Movement Guidance and Control System (A-SMGCS) utilizes Lift-Off distance (LOD) calculated by the Flight Management Computer (FMC) to check if the computed lift off distance is available on the assigned departure runway. The proposed solution aids the controller in selection of departure runways which are sufficient for the aircraft.

ABSTRACT

With increasing demand for air transportation, the air traffic at airports is increasing

exponentially. Initiatives such as NextGen and SESAR are being implemented to allow

aircraft to fly close, take direct routes and avoid delays at the airports. Delays associated

with aircraft waiting for departure clearances is rising with increasing air traffic. Currently,

the controller assigns a departure runway for each aircraft based on aircraft type. At times,

the assigned departure runway may be insufficient for the aircraft, as the controller may

not be aware of current aircraft load and thrust settings. Communications between cockpit

and the controller regarding sufficiency of the assigned runway leads to delay in

departure. This leads to increased queue for departure clearances and reduces efficiency

of operations. The proposed solution utilizes the connectivity between cockpit and ground

systems. An Advanced Surface Movement Guidance and Control System (A-SMGCS)

utilizes Lift-Off distance (LOD) calculated by the Flight Management Computer (FMC) to

check if the computed lift off distance is available on the assigned departure runway. The

proposed solution aids the controller in selection of departure runways which are sufficient

for the aircraft.

1. INTRODUCTION

Currently, the controller assigns departure runway for each aircraft based on aircraft type

and runway availability at an airport. The controller calculates if the assigned runway is

sufficient for a type of aircraft before clearing the runway for departure. Currently, there

are many instances when the assigned runway for the aircraft is cleared without checking

2

aircraft parameters. The aircraft parameters can include, but are not limited to, ability to

perform the takeoff for current configuration, takeoff weight, and airframe capacity.

Further, there are chances of manual errors in calculation. Based on the received

departure runway from the controller, the pilot checks if the aircraft can perform the takeoff

for available runway length with current load sheets, outside temperature, and thrust

settings. In many cases, prior to take off, the controller and the pilot exchange

communications on the cleared departure runway if the pilot feels that the aircraft may

not be able to perform lift off on the assigned runway. Negotiations between the controller

and the pilot can be time consuming. Further, assigning a runway gets more complicated

when runways are partially closed or if declared runway distances are different than the

runway distances referenced by onboard navigation systems.

To aid the controller with calculations, systems such as Advanced Surface Movement

Guidance and Control System (A-SMGCS) are used for route planni...
