520 ‡aA practical method of determining measuring system requirements for instrument low visibility approach is presented. The method is made to depend on system analysis of the airplane, its control system, and the guidance system, as well as on atmospheric turbulence inputs and radio guidance system fluctuation noise. Requirements on the system are set in terms of a low value of the accident exposure multiplier which is related to the probability of a missed approach in the assumed environment. The application of the method is demonstrated in connection with two examples: manual-flight director approach in the A-7D attack airplane, and automatically coupled approach with an advanced 'windproof' flight control system in the DC-8 transport aircraft. The results, including particularly the implied requirements on scan rate for a scanning beam instrument low visibility approach system, demonstrate the interconnections between scanning rate, flight control, and overall system performance.
