From Gloucestershire to Shoreham via Lewknor Briefing by: Tony Driver.
  Briefing Tuesday 15th April 2008  
Introduction This is an event to say thank you to Mike Pike's real world counterpart, the former Senior ATCO and now Operations Manager at Gloucestershire airport, Darren Lewington.
Mike says: 'I have spent many a happy morning in the control tower with him and his staff learning how they do this air traffic control lark for real. I can safely say that he is the main reason why I am able to make the virtual Gloster Approach sound so authentic. He has been very supportive.
Last summer he was diagnosed with cancer but has made a full recovery. He and his colleague Rob are making a sponsored free-fall parachute jump in Mid April at Lewknor and on Tuesday 15th April, we will undertake a cross country navigation exercise to the site from Gloucestershire airport and then on to Shoreham. The coordinates from Pooley's Guide are N51 40.25 W000 58.82. The site is west of Lewknor village just off Jn 6 of the M40 but in my scenery there is nothing to see but a patch of grass in a cornfield.
If you would like to read about Darren's sponsorship request for this jump have a look here. As you will see, he still has a great sense of humour.'
Start Time and Place 19:30 zulu - The CIX Hangar at Gloucestershire.
Departure and Duration We will depart and fly individually or in small groups. The distance is approximately 115 nm. The following times do not include time spent on the ground.
Cruising at 105 knots, the flight will take about 1 hr 5 mins.
Cruising at 180 knots, the flight will take about 40 mins.
Weather ...or not Before starting we will check the weather en route. If it is unsuitable for our trip as planned, then we will fix it. Something we can do in the simulator - wouldn't it be nice if we could do it in real life!
FSInn has a "CAVOK" button. Click this and you get calm clear weather.
Those using SB3 will need to turn off the on-line weather updates, and select calm in the FS weather options.
Routing Overview The route will take us to the north of RAF Benson, via the Northleach Roundabout VRP, and over Kidlington, crossing the Benson MATZ to circle over Lewknor. We will use the NDB and DME at Kidlington to help locate Lewknor. Leaving Lewknor we turn towards the Woodley NDB, then to the Guildford VRP and the Washington Intersection VRP to Shoreham
Club members will find more information in the Events forum.
Flight Plan Your flight plan should show: departure = EGBJ, destination = EGKA, alternate = EGHR, route = Northleach Roundabout VRP - Kidlington - Lewknor - Woodley NDB - Guidlford VRP - Washington Intersection VRP, and comments = /V/ DAYLIGHT / CIX VFR CLUB
All bearings and headings given in the briefing below are magnetic, and no allowance has been made for any cross wind.
Airfield charts and information for UK are available from the AIS web site. You need to register, but it's free.
Don't forget to include information for your alternate destination, in case you need to divert.
Two spreadsheets have been prepared, with Flight Plans for different cruising speeds: one for a Cessna 172, and the other for a Beech Baron 58. Each covers both the outbound and return flights.

Gloucestershire to Lewknor

Before departure, file your flight plan, set your ADF radio to GST 331.0 with standby OX 367.5, and NAV1 radio to 115.55 with standby 117.70 - these are the Gloster and Kidlington NDBs and TDMEs. Set your transponder to 7000. Set the local QNH by pressing the 'B' key. Contact ATC for taxi instructions and clearance for your departure as filed. Follow the instructions you are given to taxi out to the active runway. Set squawk mode Charlie as you take up the runway. Departure will be to the east, to the Northleach Roundabout VRP. Your track from Gloucestershire is 106 for 13nm. You can make use of the Gloster NDB to check your outbound track. It should point to 286 degrees. The Gloster TDME will show the distance from Gloster.
As you reach the Northleach Roundabout VRP, turn to 092 for a further 19nm. Swap your radios to the Kidlington ADF and TDME to check your track.
Leave Kidlington on 130 degrees for 16nm to Lewknor, crossing the Benson MATZ. Lewknor is on the edge of the zone. Make a left hand orbit over Lewknor.

Lewknor to Shoreham

Over Lewknor, set your ADF radio to WOD 352.0, and turn towards it. Your track should be 167 degrees, and the distance 14nm.
From Woodley head 142 for 17nm to the Guildford VRP
Set your radios to the Shoreham Navaids, ADF to SHM 332, and NAV1 to the TDME on 109.95.
Over Guildford, turn to 163 for 21nm to the Washington Intersection VRP
From there, Shoreham should be in sight a further 6nm at 138 degrees.

Divert to Goodwood

If you have to divert to Goodwood, it is 18nm at 275 degrees from Shoreham. Use the Goodwood VOR/DME, GWC 114.75 to help you find it.

NDB and VOR Tracking

The Instrument Flight document in the Training section of the club web site contains a section on NDBs and how to use them. If you are unsure how to track NDBs, download and have a look at this.
The document covers the use of VORs for direction and distance measurements as well.

Radio Discipline

Take care not to let our Teamspeak chat cut across ATC. Stop any conversation immediately the R/T comes alive, then continue if "he wasn't talking to us". This is difficult because when transmitting on Teamspeak you can't hear the R/T. So be brief on Teamspeak, and be aware that ATC might be trying to get through. If anyone hears an R/T message which seems to be being ignored, just say "ATC is calling G-CIXN" if you have identified the callsign, or "ATC is calling us" which is a cue for everyone to be quiet on Teamspeak until ATC call again (which they will). Remember too that if asked to "Stand By" by ATC, you do not reply - not even "Roger", but simply wait until you are called again.
Remember also that there are several different ATC frequencies in use, and you may not be able to hear when communications are taking place. Make sure you have set and know how to use a Teamspeak mute switch.
