The CANP procedure (commonly referred to as a NOTAM, which it isn't) is a way of informing low flying military aircraft of where we will be flying.
The technical definition is:
A voluntary system whereby civil operators notify their intention to fly at low level (at or below 1,000 feet agl, when crop spraying or powerline inspecting for example), aimed at avoiding conflict with low flying military aircraft.
There are two linked systems for letting the military know where we will be flying on any given midweek (non English bank holiday) day.
Five hundred of the busiest flying sites in the UK have allocated Site Codes. You can find these by going to the site page and looking for the Site Code - for example, Balladen is 8.052. On these sites it is possible to activate a temporary avoidance zone around the notified site (1nm diameter/1000ft agl) by contacting the Low Flying Booking Cell by 20:00 the day before (16:00 on Sun). (Later submissions will still be passed on to military pilots, but as a warning rather than creating a temporary avoidance zone.)
For all other sites the standard CANP (Civil Aircraft Notification Procedure) should be used if five or more gliders are likely to be operating. This does not establish an avoidance area but it does ensure that military pilots will be alerted to your presence. Because it can take up to four hours to get the information out to all the military pilots before they take off, the notification procedure should be started as soon as possible - ideally the evening before.
The Low Flying Booking Cell would prefer if we co-ordinate our activities so that we don't duplicate notifications. So if you intend to fly a site, take the following steps:
Follow the PSC on Twitter or Facebook - see if anyone else has notified the site for the day and time that you intend to fly.
If the site has already been notified, you don't need to do anything.
Ring Freephone 0800 515544 (Fax 0800 3892225)
Provide the following details:
State "Hanggliding or paragliding". If the site is one of those with a site code then state "Hang/paragliding Avoidance Area" here.
If the site is one of those with a site code then state that first. Then provide the site grid reference (2 letter 6 figure) and it's name e.g Larkhill is SD 998 080. Quote the grid reference in the site guide as this is the recognised grid reference.
AREA OF OPERATION
With the notification system this is a maximum of 2nm radius. With the avoidance area system it is always 1nm diameter.
DATE / TIME
Date and time flying will start/finish. They prefer a date in 10 October 2012 format (i.e. no day suffix and month in text) and times in 24 hour format
EXPECTED NUMBER OF GLIDERS
CONTACT PHONE NUMBER
Ideally a mobile that will work on the site
Normal contact details if different from above.
You will be given a unique Reference Number to note.
The Low Flying Booking Cell is manned Monday to Thursday 07:00 - 23:00 and Fri to Sun 07:00 -17:00. If you use the fax out-of-hours you will be called back by phone with the Reference Number when the office is next manned and the associated notification has been passed to military pilots. You can only assume that you have avoidance/notification status once you have received this.
If you do not fly, for whatever reason, phone again and cancel your notification quoting the reference number. For maximum effect the Freephone should be called at least 4 hours before you fly, and remember, Freephone does not give you exclusive access to the site, it simply warns the RAF pilots that there is very likely to be low slow moving traffic rather than just maybe.
