A nameof the Flight) and the Unique Code for

A cockpit or flight deck is the area, usually near the front ofan aircraft, from which a pilot controls the aircraft. Mostmodern cockpits are enclosed, except on some small aircraft.The cockpit of an aircraft contains flight instruments on aninstrument panel, and the controls that enable the pilot to flythe aircraft. In most airliners, a door separates the cockpit fromthe aircraft cabin. The existing flight recording system iscockpit black box. It is now orange-colored, is an electronicrecording device placed in antiaircraft for the purpose offacilitating the investigation of incidents. Any type of aircraftin any condition of flight can be viewed in terms of its inputparameters (e.g. control instructions) and output parameters(e.g. flight sensors), without any knowledge of its internalworkings, as a black box model 1.This paper focuses on the advanced version of cockpitblack box, which is cockpit white box. Unlike black box, whitebox includes on-time recording of information and replay isalso possible. It consists of two sides: Cockpit side and ATCside. The cockpit side consists of the interfaced software so asthe pilot to interact with the system and the sensors to give thedetails of the speed, flight-level, and the direction. It alsoconsists of an internal system to define its call sign (the nameof the Flight) and the Unique Code for authentication of theFlight. All the above details are sent to the base-station. Thecontrol base at ATC side accumulates all the incominginformation from the microcontroller, and display using VBfront end on PC.Cockpit white box is designed with ATMEL(AT Mega328) microcontroller, LCD, UART, sensors, GPS and RFmodule. This project contain two modules one at aircraft andanother at Ground station. Aircraft module reads fuel, speed,engine temperature, direction of aircraft and continuouslysends data to ground using RF module 2.II. BLOCK DESCRIPTIONA. Cockpit SideBlock diagram of cockpit side consists of ATMELmicrocontroller, LCD, buzzer, driver circuit, fuel sensor,temperature sensor, speed sensor, direction sensor and RFtransmitter.Fig.1. Block diagram of cockpit side1) ATMEL Microcontroller: It is the heart and wholecontroller of this project. It is an 8bit processor with lot ofperipherals. The AT89C51 is a low-power, high performanceCMOS 8-bit microcomputer with 4K bytes of FlashProgrammable and Erasable Read Only Memory (PEROM).The device is manufactured using Atmel’s high density nonvolatilememory technology and is compatible with theindustry standard MCS-51TM instruction set and pin out.2) Temperature Sensor: LM35 IC is used for temperaturemonitoring. It’s structure is same as BC547 4. This ICconsists of three pins: Vcc, GND and Vo. It’s output voltage(Vout) is equal to the Vcc, that may vary due to change intemperature. Vout will be the degree Celsius value oftemperature. Analog voltage is read out and 100 samples aretaken and average value is calculated. In order to varytemperature, a soldering iron or any hot object is brought nearthe surface of the IC. When the IC senses hot object near it,temperature value increases otherwise it shows the room
