GNSS for IFR flights. Learning material for students and instructors

Pilots flying IFR (Instrument Flight Rules) nowadays are expected to come across with GNSS usage. The main reason behind this is that the RNAV 5 (alias Basic RNAV) navigation specification is mandatory above FL095 in almost the whole European airspace. Today’s knowledge for IFR flying is insufficient for safe and trouble-free flying in the PBN environment. As the EASA’s new regulation (EU 2016/539) is resolving this issue with the requirement of a PBN clause to Instrument Rating, it will be in effect from 25 August 2018. The first section (part A) of this publication was designed to guide General Aviation (GA) pilots towards basic principles of PBN. The GNSS receiver is almost an exclusive navigation device used in GA which enables PBN operations. Therefore, the publication is GNSS-orientated. The second section (part B) provides Learning Objectives identified by the CaBilAvi project consortium, as they are relevant and important for PBN flying and missing from the required theoretical knowledge of pilots. The proposed Learning Objectives are explained throughout part “B”, and they are relevant to every Instrument Rated pilot and beyond. Due to the structure of the proposed Learning Objectives, some of the content of this Part may be duplicate to part A. On the other hand, part B is also incorporated into the e-learning application available for free use on CaBilAvi project webpage (http://cabilavi.gnss-centre.cz/web/elearning)
