Problems solved by technology

Another way is to monitor the flight technical error (FTE) through the lateral deviation indication, that is, the full scale of the lateral deviation is the limit value of FTE, and the pilot can ensure that the FTE does not exceed the limit value by observing that the lateral deviation does not exceed the full scale, while The navigation system error (NSE) needs to be alerted through the algorithm of the flight management system, which cannot be displayed intuitively on the display
Another way is to display both FTE and NSE on the lateral deviation scale band, and the NSE value is coupled to both sides of the lateral deviation scale band. This method is more intuitive than the previous two methods to see the direct relationship between NSE and FTE, but No limit value is given for NSE

Embodiment Construction

[0029] Embodiments will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References made to particular examples and figures are for illustrative purposes and are not intended to limit the scope of the invention or the claims. The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as superior or superior to other implementations.

[0030] During RNP operation, it is necessary to monitor RNP-related errors in real time and provide an alarm when the error exceeds the limit value. In general, the total systematic error (TSE) of RNP is divided into FTE and NSE. Common allocation methods may include, for example, following one of two formulas:

[0031] TSE = FTE + NSE (1)

[0032] TSE 2 =FTE 2 +NSE 2 (2)

[0033] ...

Abstract

The invention relates to a method and equipment for displaying required navigation performance (RNP). The method comprises the following steps: showing at least two parallel bar frames, one or more first bar frames in the two parallel bar frames show NSE, and one or more second bar frames show FTE.

Description

technical field [0001] The present disclosure relates to the field of aviation navigation, in particular to the field of Performance Based Navigation (PBN) in Aircraft Communication Navigation Surveillance / Air Traffic Management (CNS / ATM), and is suitable for aircraft display supporting RNP operation. Background technique [0002] There are usually several ways that RNP display schemes. One way is through numerical display, that is, directly displaying the actual navigation performance (ANP) value and RNP value on the display, and monitoring and warning through the comparison between the two. Another way is to monitor the flight technical error (FTE) through the lateral deviation indication, that is, the full scale of the lateral deviation is the limit value of FTE, and the pilot can ensure that the FTE does not exceed the limit value by observing that the lateral deviation does not exceed the full scale, while The navigation system error (NSE) needs to be alerted through t...
