The patterns in this document combine observations, reinterpretations, rational reconstructions, and redesigns of Avionics Control Systems within the realm of the DSSA ADAGE project[3]. An Avionics Control System (ACS) is the main navigation system of an aircraft. An ACS continuously collects sensor data to estimate actual state of an aircraft, computes desired aircraft state with respect to gu...

The continuing development of fully autonomous aircraft requires advanced sensing and control systems in order to complete difficult tasks such as aerial refueling and close formation flight. To accomplish such maneuvers, an aircraft must be able to measure the location of nearby aircraft and position itself relative to these other flight vehicles. In visually degraded environments where vision...

The increased complexity of next generation aircraft has popularized Multidisciplinary Design Optimization (MDO) as an aircraft design tool. However, MDO efforts consistently neglect aircraft stability and control analyses beyond simple static assessments. Not only does this limit the potential of the MDO to identify an optimal design, but it also fails to assess the MIL-STD or FAR handling qua...

This paper presents results of a recent experiment in fine grain Electromyographic (EMG) signal recognition. We demonstrate bioelectric flight control of 757 class simulation aircraft landing at San Francisco International Airport. The physical instrumentality of a pilot control stick is not used. A pilot closes a fist in empty air and performs control movements which are captured by a dry elec...

In past, the aircraft control systems were based on conventional methods of mechanical and hydro-mechanical system. The present generation aircraft are using fly-by-wire (FBW) and in future likely to migrate to fly-by-light (FBL) method for aircraft control system. Mechanical & Hydromechanical flight control systems have been replaced by FlyBy-Wire due to increasing speed of modern aircraft. Du...

Loss-of-Control (LOC) is a major factor in fatal aircraft accidents. Although de nitions of LOC remain vague in analytical terms, it is generally associated with ight outside of the normal ight envelope, with nonlinear in uences, and with a signi cantly diminished capability of the pilot to control the aircraft. Primary sources of nonlinearity are the intrinsic nonlinear dynamics of the aircraf...

Aircraft deicing fluids rapid heating system is widely used in aircraft ground deicing to ensure that the operation of flights can be safe and efficient. Aiming at the temperature turbulence problem of aircraft deicing system, this paper presents the single neuron PID control strategy which combine the advantage of conventional PID control with artificial neuron control. The aircraft deicing fl...
