Re: UK AIS
Following last Thursday’s meeting at NATS, AOPA have a number of concerns.
Most Airfields have not been displaying NOTAM information for self-briefing by pilots. Where anything is
displayed it is not to any standard.
There is no backup for when the AIS site fails and at the moment no time-frame for providing one. AIS
do not have enough capacity to provide a telephone backup service that would approach the capacity of
the web-based system.
There is no provision for anyone without web access to obtain a written brief other than by asking the
Duty Officer to fax a brief.
These issues will not be dealt with until the standardised one-button brief is available (expected April 2003)
and has been made available for fax download, which will inevitably be at some later date.
We therefore request that the A1/A8 bulletins be made available as an interim measure until the following
conditions are met:-
The one-button download has been made available, has been properly trialled, and has gained general
The standardised brief has also been made available for fax download, has been properly trialled, and
has gained general user acceptance.
At least one month's notice has been given to users of the cessation of the interim arrangement
following the above.
We also request that the AI/A8 and its successor, the one-button brief, should be made available from a
different server to ais.org.uk or should be mirrored on to other servers so that it would remain available to
users in the event of a failure of the main server.
Pending provision of fax download facilities we ask that the A1/A8 (or the one button download when
available and tested) should be available on request from the Duty Officer via fax or e-mail for callers who
are unable to obtain satisfactory Web access.
These proposals would bring a number of important benefits:-
A standardised brief would once more be available at aerodromes.
A back-up would be provided in the event of further problems with ais.org.uk
The AIS Duty Officer would have a standardised brief available pending the introduction of a fax
download of the new one-button brief.
Users who have stopped checking NOTAM because of a lack of confidence in the new system would
start doing so again. They would be able to verify the accuracy of the new system by comparing it with
Those who prefer to use a standardised rather than an interactive brief could easily be encouraged to try
the new one-button brief by means of links to the new briefs.
When the A1/A8 bulletins are eventually withdrawn a link can be provided to automatically re-direct
users to the new briefs.
In terms of cost this would be very cheap to implement:-
The A1/A8 are already being compiled so there would be no additional cost of compilation.
The files could be hosted on another web server (e.g. nats.co.uk) at very little cost.
I look forward to your response.
