Use the Correct BARO Setting for Approach
Using an erroneous barometric reference setting during approach may cause the aircraft to fly lower than the published approach path, when the vertical guidance and trajectory deviations use the barometric reference. This can lead to a risk of controlled flight into terrain in poor visibility conditions or at night.This article explains the potential consequences of an erroneous barometric reference. It also provides guidance to flight crews on how to detect it, and describes the available system enhancements to alert flight crews when an erroneous BARO reference is detected.
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.
