Novel precise sea-way entering indication method and system

Abstract

The invention discloses two methods for accurately guiding the sea-route and relative systems. The first method (MPAPI system) comprises three lamps while each one has three light units, and each light unit can irradiate yellow, green and red lights, wherein, the angle of green light is symmetry distributed on the sea-route; the angles of yellow and red lights are individually layered distributed from the upper and lower angle lines of green light. The second method (MPAPI2 system) comprises four lamps, while each light unit irradiates two lights of yellow, green and red lights. The invention only uses red, yellow and green lights, especially the MPAPI system uses three lamps to supply accurate guide to the pilot. The invention can apply the accurate guides of variable planes; therefore, the pilots can adjust the plane figures to improve the landing accuracy and safety.

Description

technical field [0001] The present invention relates to an indication method and system for aircraft precision approach, in particular to a novel precision approach course indication method and an indication system (MPAPI) for implementing the method, a method that can provide seven types of higher-precision visual glide slopes for approach aircraft New precision approach course indication system for range indication. Background technique [0002] There are currently three approach slope indication systems: [0003] 1. General visual approach gradient indicator (GVGI): [0004] 1) The general visual approach slope indicator can only provide pilots with three approach slopes on the approach path (the system specifies that the approach path width is 0.33 to 0.5 degrees), above the approach path, and below the approach path indication signal. [0005] 2) The system is composed of multiple lamps, each lamp uses a light source and a single color, the optical system is placed v...

Problems solved by technology

[0033] The purpose of the present invention is to provide two novel precise approach channel indication methods and the corresponding system for implementing the method, to solve the problem that the existing GVGI has low indication accuracy and is difficult to find the correct approach channel; the white light fog-breaking ability of PAPI exists Poor, it is difficult to distinguish in the case of poor visibility or fog, in the case of only one pilot, it is difficult to complete the approach alone in a short time, and the debugging is complicated, and a special calibration aircraft must be used to check each lamp A series of problems such as correction of elevation angle
