Transcript Bristol airspace changes - Avon Hang Gliding & Paragliding

Bristol airspace changes
and how they affect us…
Background
• Air traffic in and out of Bristol and Cardiff is
growing
• Bristol and Cardiff airspaces are merging
and expanding
How does this affect us?
• The “Bath Gap”
• Ubley
The Bath Gap - now
The Bath Gap –

Activation
• Can only be activated between 1000 local
and 1900 local or official night (whichever
is earlier)
• Can be activated by the local gliding clubs
and by five nominated members of the
Avon HG & PG Club
• Can only phone Bristol ATC no earlier than
2 hours prior to the ETA of the first glider
at the boundary of the Bath Gap
In practice
Having arrived at Leckhampton (or Mere)
1. Phone Bristol ATIS (01275 473666) to check
whether the Bath Gap has been activated
2. If yes (and this will most often be the case), no
further action needed
3. If no, contact one of the five nominees (Tim
Pentreath, Ken Wilkinson, Stafford Evans, Nev
Almond & Richard Hellen) who will phone up
and activate the Bath Gap
4. Wait a few minutes and then confirm by going
back to step 1
Glider Flight Rules
•
•
Gliders operating within the Bath Gap
are to operate in accordance with VFR at
all times (ie. 500’ below cloud!)
NB. IFR traffic (ie. airliners) will remain at
least 500ft above the glider block (ie.
5000’)
Ubley - now
Ubley – after 31st August 2006
• The Ubley Glider Block is a chunk of airspace
from 1500’ to 2500’ that can be activated to fly in
• If flying xc you will also want to activate the
Halesland Glider Block which is south of the
UGB
• This raises the base in this part of the CTA from
3000’ to 4000’
• Activation will work in the same way as at
present - ie. calling Bristol ATC on 01275
473714/15, not one of the five Bath Gap
nominees
