The Air Data System (ADS) is measuring the various data of two different air craft or air plane. The Air Data System (ADS) is measuring the various data of the air craft by the help of some various instruments or devices. The various data or information of the air craft is collecting the various data such as, the pitot pressure, static pressure, temperature of the air craft devices or instruments, flow angles of the air craft or air plane, angle of attract, angle of sideslip of the air craft or air plane (Di, Wu and Zhou, 2014). This all various data or information are measuring for the better control and manage the air craft or air plane. This all various values are analyze by the help of some various parameters like position of the air craft or air plane, velocity of the air craft, attitude of the air craft, angular rate and liner acceleration of the air craft or air plane. 2. The Pitot-Static air data system is the analysis value or part of the air data system of the air craft or air plane. The Pitot Pressure is the value of the total sum of the static pressure and the increasing value of the dynamic pressure or air flow rate of the air craft or air plane. This pressure is situated in pitot tube. The Static pressure value or rate is measuring by the help of the pitot-static tube of the air craft or in other word, the static pressure rate or value is calculating by the help of the flush mounted port, which is present in the fuselage of the air craft or air plane. Other variable like, total pressure is measuring very accurate by air data system. The pitot tube opening is depends on the air crafts outside layers and the air flow in the direction of incoming. The pitot tube shape and size is always dictates the flow angle of air craft or air plane (JuhaÃÅ' sz, Kacsuk and KranzlmuÃÅ'ˆller, 2005). 3. In todays modern technology the presence of digital and analog signal are quite important. The digital data is considered important as it stores from 0 to 1. Whereas the analog data is the data that produces continuous waves that represent a certain amount of values for indication. The basic advantage of the digital data over the analog data that is recorded for better usage and it also makes sure that the quality is not lost even if it is copied for a numerous times for maintaining the same quality. The analog data signal is quite low in quality for the transmission. The transmission of the analog data signals for the long transmission is in very bad quality, which is difficult for the analysis by air data system. The low quality of the data signals is due to the induction and the resistance in the wire (Forlenza et al., 2012). As well as the digital signals is like original signals. The digital data signal of the air craft or air plane is transmit or send one device to other device to 16 bits. The digital signal of the air craft is much faster than the analog signals, but some time the digital signals are lost due to some bad quality of the data transmission over one device or instrument (sending device) to other device or instrument (receiving device). 4. The Flight Director System (FDS) is the system which is consists by the help of various devices or instruments of the air data system. The Flight Director System (FDS) is without any trouble interpreted display path or route of the air craft or air plane. The Flight Director System (FDS) of the air craft is fully pre programmed system, which is consist according to the requirement of the air craft or the controller. The main section of the Flight Director System (FDS) are Flight Director Indicator (FDI), Horizontal situation Indicator (HSI), air craft director system or computer and also mode selector of the air craft or air plane (JuhaÃÅ' sz, Kacsuk and KranzlmuÃÅ'ˆller, 2005). 5. The three types of air display system in integrated flight system are Primary flight display, Multi Function display and electronic centralized aircraft monitoring. Primary flight display If we look at the flight deck we can figure out the display units that are the most important part of the EFIS system and the features that are termed as glass cockpit. This display unit secures the place of the ADI and is often termed as primary flight display. Multi function display The MFD displays all the weather and navigational system. These MFDs are designed quite frequently that are quite chat-centric (Lu et al., 2015). The aircrew system forecasts all the information that is displayed on a map or chart. The examples of the MFD information student include the route plan of the aircraft. Electronic centralized aircraft monitoring (ECAM) The EICAS that is also known as the engine indication and the crew system display all the information that is related to the aircraft system and at the same time includes the propulsion and the electrical system. The EICAS are often designed for traditional round gauges that supplies digital reading of the parameters. 6. The construction and operation of the integrated flight instrument system are stated below: The flight director system: The use of system inputs, computation, Horizontal situation indications, aircraft control panels, interface to the aircraft system and other mode selectors (Redling, 2001). Electronic Display: The alphanumeric displays, ambient light sensors, symbol generation, cathode ray and liquid crystal. Electronic flight instrument system: Electronic indicator system, electronic horizontal indicators, system input device, aircraft case study, reliability and failure.
