Everything you want to know about your intended launch site.
The UKRA
maintain a list of registered sites in the UK. If you want to launch from one
of those, then contact the UKRA
and they will put you in touch with the person responsible. They will explain
if you can join the club that uses it or how you go about getting permission o
use it.
If you have your own land or access to private land, then you
must abide by the following when assessing if the site is suitable for
launching/recovering rockets:
-
The site must be large enough. This is detailed later.
-
The site must not be within 5km of an airport or in an approach path to a main airport.
-
The site must not be in restricted airspace, or of it is, you must ensure that
you fly below the restricted height.
-
You must have permission from the land owner
-
You must abide by all local Bye Laws

Probably one of the most common questions. Your launch site
has to be at least big enough to allow you and spectators to stand the minimum
safe distances back from the rocket, but more importantly it has to be large
enough to recover the rocket. The
UKRA have published some minimum launch site data.
