Abstract

Electronic Flight Bag (EFB) is an electronic information management device that helps pilot to perform flight management tasks easily and efficiently. There is a challenge in mounting the EFB device in a location that can be easily accessed by the pilots. This paper talks about a communication system to provide easy access for the pilots to the EFB device. The proposed solution provides an Infrared Data Association (IrDA) port along with a cursor control device (CCD) which can be used to communicate with the EFB device. The data transmission from the CCD can be provided by using IR LED(s) and the data reception by the EFB device can be made possible by using IR photo-diode(s). A selection button can be used to switch communication from the CCD to FMS (Flight Management System) or to the EFB device.

SMART WIRELESS COMMUNICATION FOR ELECTRONICS FLIGHT BAG DEVICES

ABSTRACT

Electronic Flight Bag (EFB) is an electronic information management device that

helps pilot to perform flight management tasks easily and efficiently. There is a

challenge in mounting the EFB device in a location that can be easily accessed by

the pilots. This paper talks about a communication system to provide easy access

for the pilots to the EFB device. The proposed solution provides an Infrared Data

Association (IrDA) port along with a cursor control device (CCD) which can be used

to communicate with the EFB device. The data transmission from the CCD can be

provided by using IR LED(s) and the data reception by the EFB device can be made

possible by using IR photo-diode(s). A selection button can be used to switch

communication from the CCD to FMS (Flight Management System) or to the EFB

device.

1. INTRODUCTION

A flight management system (FMS) is a fundamental component of a modern airliner's

avionics. An FMS is a specialized computer system that automates a wide variety of in-

flight tasks, thereby reducing the workload on the flight crew. Cursor Control Device

(CCD) is an electronic input device which allows pilots to select, guide, or influence the

operations of the FMS through a cursor on display.

An electronic flight bag (EFB) is an electronic information management device that

helps a flight crew perform flight management tasks easily and efficiently. It is a general

purpose computing platform intended to reduce or replace, paper-based reference

material often found in the pilot's carry-on flight bag, including the aircraft operating

manual, flight-crew operating manual, and navigational charts. Mounting the EFB device

in a comfortable location that can be easily accessed by the pilot is a challenging task.

Hence, a mechanism is required to provide easy access and communication with the

EFB device.

2. PROPOSED SOLUTION OF THE PROBLEM

The proposed solution provides easy access to the EFB device using the cursor control

device (CCD). The CCD can be a touchpad or a trackball which can act as a human

machine interface (HMI). A CCD controller is provided along with the CCD to process X-

Y data received from the HMI. The CCD is provided with an Infrared Data Association

(IrDA) port that works based on optical wireless communication (OWC). IrDA is a

standard for transmitting data via infrared light waves without any cables. The

prerequisites to facilitate IrDA communication includes IR LED(s) with a reflector

mounted in the CCD and IR photo-diode(s) with a lens placed in the EFB device. While

the IR LED(s) are used to transmit the processed X-Y data from the CCD, the IR photo-

diode(s) are used to receive the transmitted data. The data transmission from the CCD

to the FMS or the EFB device is controlled by using a selection button. Based on the

button selection, the processed X-Y data is transmitted to the FMS through ARINC...
