GNSS Interference
Signals from the Global Navigation Satellite System (GNSS) are one of the main inputs used for aircraft positioning or time reference for Communication, Navigation and Surveillance functions on-board most of the Airbus aircraft.Operators report an increasing number of events related to the loss of GNSS signals due to Radio Frequency Interference (RFI) during operations in some areas of the world.This article explains the causes of RFI, the effects on the aircraft systems and provides recommendations for flight and maintenance crews.
Safely Flying Non-Precision Instrument Approaches
Historically the distinction between flying ILS/MLS and non-precision approaches was very clear. However, many new kinds of instrument approaches are now available and this makes the distinction less obvious. What remains true today for any approach is that disregarding basic flying techniques and procedures reduces safety margins.This article clarifies which technologies are available to perform approaches using an Airbus aircraft. It also emphasises the safety messages that are important to remember whenever flying an approach.
