If you're lucky enough to be able to fly on weekdays then you should be aware that you may well be sharing the air with low-flying military traffic e.g. Hercules from Brize Norton or helicopters various from Middle Wallop or Odiham. There is also the occasional fast-jet from Boscombe Down or Salisbury Plain. You would therefore be wise to notify the military via CANP (Civil Aircraft Notification Procedure) .
The details on how to do this are on the BHPA website https://www.bhpa.co.uk/documents/safety/canp/
Here's a form I made that takes all the thinking out of this process!
It is each pilot’s responsibility to check the NOTAMS provided by the National Air Traffic Service Ltd. This applies to both local site flying and XC.
They are available at www.nats-uk.ead-it.com/public/index.php.html. This site requires free registration, but it is possible with the Narrow Route briefing facility to restrict the list to only those NOTAMS relevant to where you intend to fly. Alternatively you could use www.nats.co.uk/operational/pibs/index.shtml. This site does not require registration, but provides just a plain listing of all NOTAMS. There are many programs available to us now that will plots NOTAMs over a map of the UK, this makes it easier to see which are relevant to the area we are intending flying in.
If you are unable to use the web based services then use the AIS (Aeronautical Information Service) Information Line: 0500 354802.
This telephone information line provides pre-recorded information on UK Airspace Upgrades and Temporary Restricted Areas notified within the UK. It is regularly updated and only contains information on activities taking place for that day.
A great alternative and simple tool is http://notaminfo.com/. It's free and once registered you can obtain graphical representations of the NOTAMs.
Also check the club website for latest site news. If you are not able to do this call the Sites Officer. If you are unable to contact the Sites Officer then contact another member of the committee.
