This report collects and summarizes the results of a series of engineering design studies and tests of methods for acceleration augmentation of airplane control systems for approach and landing. Emphasis was on the use of body-mounted accelerometers, which are reasonably inexpensive. Control laws were developed for several aircraft (CV-880, DC-10, B-727) and tested by simulation with both automatic and human pilots; they included automatic landing systems, flight director with full ILS, and flight director for nonprecision approach. The modified flight director (MFD) control algorithms (pitch, roll and thrust) were also tested in large-scale piloted flight simulations under Task 2 of the AWLS project. The objectives were to achieve approach-and-landing performance on Category I and II ILS beams comparable to that with current systems on Category III beams, and to obtain improved performance over current systems in coping with low-level wind shear. The low-cost system designs met these objectives, and exhibited performance comparable to that attainable with an expensive full inertial navigation system. Collins supported tests of the methods in DC-10 and B-727 flight simulators. The MFD controls were implemented in a Gulfstream I test airplane for FAA tests. (Author)
