In June 2017 FASVIG submitted a document to the CAA proposing improvements to Aeronautical Information Management (AIM) data. Please see below for details of the proposals.

The CAA have now responded to FASVIG’s proposals. The response from the CAA can be read here:


14th June 2017AIM Effectiveness for Single Pilot VFR Operations

FASVIG has published a new 5 page document proposing improvements to AIM data. Here is an extract from the document, which can be accessed via the link below.


1.0 The FASVIG Implementation Programme (FASVIP) contains an AIM efficiency enablers element which has significance to airspace safety and infringement reduction. FASVIG sought views from VFR stakeholders and from providers of GPS mapping devices and services commonly used by pilots flying VFR in the UK. Its objective was to identify policies that tend to make the user interface less effective than it might be and propose potential changes to improve airspace safety and support infringement reduction. As GPS mapping devices are developed the displayed AIM information and warnings are increasingly focussed and reliable pilots rely on the information and honour warnings and information messages. However, where displayed information is not relevant to the route flown or the time of flight, pilots have to make a decision to honour or ignore the information. Forcing pilots to make such decisions invites error and reduces airspace safety.

1.1 FASVIG produced a report of the same title as this proposals paper dated 28 Sep 2016 that was submitted to the CAA. This proposals paper is to move the matters forward as a series of proposals that can be progressed as work packages. Due to FASVIG funding there is a need to gain agreement from the CAA’s NATMAC AIM Working Group for these proposals as soon as possible, and definitely by early September 2017.

1.2 The paragraphs that follow discuss these areas by FASVIP package. This work is closely allied to other FASVIG work on Listening Squawks and Airspace Infringement reduction. Where there is overlap we indicate this in the text.
