In past several applications of Fly-By-Wire (FBW) flight control systems to civil aircrafts had been experienced. In FBW flight control systems the commands for controlling of the aircrafts internal and external functions are computed by the on board flight control computer on the alkali of instructions by the pilot and without any mechanical linkage1. This resulted in the lessening of pilot workload and in general improvement of the Flying Qualities (FQ) characteristics. up to now the high development cost of a FBW flight control system made it unaffordable for the small aircrafts 2. Moreover, FBW flight control system is the ability to march aircraft configurations and parameters which provide increased aerodynamic efficiency, but at a cost of reduced natural stability. Moreover, this can cause instability of the aircraft at particular(prenominal) speeds and height conditions (or flight envelope).However, maintenance and troubleshooting of air vehicles, such as switch chanceion and monitoring systems of modern fly-by-wire (FBW) flight control system cannot detect incorrect location accurately, so that experts can t roubleshoot them in a shorter prison term. However, troubleshooting time depends mainly on the personnels skillfulness and experience 3.Flight Control SystemsFly-By-Optics(FBO) flight control systemFBO control system as the name implies that this kind of flight control system is based on the light signals which are transmitted through optical fibers. It uses electronic signals, transmitted through the fiber optics at heart the air vehicles to control the employed electro-hydraulic actuators such as flaps, spoilers, slats, ailerons and rudder, in result to input commands. Some times, it is utilize because of higher transfer info pass judgment. The data generates by the software and interpret by the controller. It is besides called as fly-by-light flight control systems.Power-By-Wire (PBW) flight control system 4Power-by-wire (PBW) is a control systems employed in near aircrafts to eliminate the bulky and heavy hydraulic circuits to deputize by self contained electro-hydrauli c actuators or electrical power circuits that are controlled by the digital flight control computers.Proposed Fly-By-Sensors (FBS) Flight Control SystemThe proposed flight control system is Fly-By-Sensors (FBS) flight control system to employ on any kind of air vehicle. As the name implies this type of control system will base on latest Zigbee technology which is low cost, low power consumption and short distance radio receiver communication technology that is developed for tuner personal area network (WPAN) 5. By using this technology, the reduction in high cost in the manufacturing of electrical wires, gross take off weight of the air vehicles, fast maculation of faulty equipment, landing and taking off of the air craft on auto pilot function of the aircraft, safety, security and so on, can be achieved.Zigbee Wireless TechnologyZigBee is similar to IEEE 802.15.4 protocol, which is a one of the latest investigate in the field of communications in short distance wireless communi cation technology. Its main advantages are low-power, short-distance, low-complexity, self organization, low-speed, low-cost, and so on. It is widely using as monitoring and controlling devices in many fields. It is suitable for low data-rate and low power consumption applications 6.Figure Difference of other wireless network standards with Zigbee earnings standards (Source www.zigbee.org)Zigbee CharacteristicsThe IEEE 802.15.4 or Zigbee standard includes the features of low power consumption that is needed just for two major modes (Tx/Rx or Sleep), high parsimoniousness of nodes per network, low costs and simple installation of devices. Following are some more features for ZigbeeIt operates on radio bands of 2.4GHz in this high band is used in most of the jurisdictions of world wide, 868/915 MHz, this lower band in the areas of northwesterly America, Europe, Australia and New Zealand.High density of network nodes which is up to 65,000 network nodes. small(a) in cost, complexity power consumption as compared to competing technologies.Data rates ranges are 250Kbps for 2.45GHz, 40 Kbps for 915MHz and 20Kbps for 868MHz band.Handshaking and 3 Frequencies bands with 27 channels.Extremely low duty-cycle (Star, cluster tree and mesh topologies can be used in Zigbee technology with the devices named as network coordinators, routers and end devices.Figure Zigbee Devices CharacteristicsZigbee Wireless Network used for landing of aircraftZigbee technology has been used for landing of the Unmanned Air Vehicle (UAV) and tested. The results showed that the recognition rate is over 90%, and the calculated delusion of position in landing of the UAV is less than 3m with 5000m distance and 0.2m with a throwaway of 500m distance. 7.Figure Landing of UAV through Zigbee Wireless Sensors Networks 7.As the Figure 3 shows the landing of UAV by using Zigbee sensors so we propose that Zigbee devices can also be used to control the aircrafts or UAVs for taking off purposes overl y so that the function of auto pilot can be used in an unfavorable climate conditions for safety and security purposes.Figure Proposed rising Concept of Taking off of the Aircraft through Zigbee SensorsProposed Fly-By-Sensors (FBS) over Fly-By-Wire (FBW) flight control SystemIn FBW flight control system, as the all electrical signals to Electro Hydraulic Actuators, Aileron, flap, rudder etc. are transmitted through wires. So the cost and weight of electrical wires limits the FBW control system to the commercial aircrafts only. Moreover, maintenance and troubleshooting of the faulty electrical wires consumes time and cost. The Safety and security of FBW flight control system is costly and non reliable for long term usage.Whereas, FBS flight control system will have the following advantages over FBW or PBWIt will be cheaper to use Zigbee technology than using electrical wires as it will costs almost 80% more than using the wireless sensors.The low power feature of Zigbee wireless sen sors makes it to use for years without rechargeable batteries.The operating radio frequency is license free that is 2.4GHz with 16 channelsFBS control system will provide the safe monitoring system for controlling the aileron, rudder, electro hydraulic actuators etc.The Zigbee wireless sensor can also provide the portion communication between pilot and co-pilot and the remaining staff for commercial aircrafts.The smart features of Zigbee technology will improve the reliability in the in-flight fault diagnostics and identification (FDI) as well as fault-tolerant control (FTC).By using Zigbee wireless sensors we will achieve the remarkable decrease in weight of the aircraft that will also help in more stability of the aircraft. At the result, there will be increase the number of passengers, goods or any material for transport purposes etc.Proposed Fly-By-Sensors (FBS) Flight Control Systems Block draw StructureFigure Block Diagram of proposed FBS flight Control SystemsAs Figure 5 s hows the commands from the Pilot or from the Autopilot function of the aircraft will transmit by Zigbee Wireless Sensor Network through the on board computer on the aircraft.
