Navigation by Dead Reckoning Briefing by: Tomas Linnet
Briefing 1st January 2018
Overview This is my first event as the newly appointed Events Manager, so I've decided to make this month's event a navigation exercise suitable for new members of the Club as well as the old hands who think they know it all! The departure airport is our Club base, Gloucestershire (EGBJ) and arrival airport is Swansea (EGFH), an airfield we haven't visited during an offical Club event since 2007.
Start Time and Place This event may be flown on any day in January. Being a navigation exercise, it may be best to fly it on your own, in order to concentrate on the all-important headings, altitude and location (visual fixes), but it is up to you.
Route

Take off from EGBJ and if possible do an overhead dearture(more info in Training Exercise 4a, as it will help you on the 1st leg.

  • GST NDB(331KHz) to NE01 heading 312°M for 34 nm
  • NE01 to NE02 heading 164°M for 40 nm
  • NE02 to NE03 heading 313°M for 37 nm
  • NE03 to NE04 heading 133°M for 19 nm
  • NE04 to NE05 heading 208°M for 7 nm
  • NE05 to NE06 heading 165°M for 5.5 nm
  • NE06 to NE07 heading 105°M for 9 nm
  • NE07 to NE08 heading 075°M for 7 nm
  • NE08 to NE09 heading 313°M for 18 nm
  • NE09 to NE10 heading 281°M for 22 nm

NE10 is the final waypoint, and with a bit of luck (and low winds) you should now be within range of the SWN NDB(320.5KHz). Proceed to EGFH and land.

Flight Planning

"Dead Reckoning" is the art of arriving where you intented to by flying a fixed heading for a precise period of time. You need to calculate the times from your planned airspeed, any heading correction due to the forecast wind and the distances given above. There is no pre-prepared Plan-G file of the route, BUT please avoid using Plan-G to navigate – part of the “fun” will be to navigate by Dead Reckoning, or by identifying ground features. (N.B. if flying in company don't blindly follow your companion – you might infringe a danger zone or controlled airspace by doing that!).

Your VATSIM flight plan should show: -
Departure = EGBJ Destination = EGFH
Route = VFR remaining outside CAS
Comments = /V/ DAYLIGHT / CIX VFR CLUB /
At 140 knots this Route should take about 1hour and 30 minutes, (plus the time from the end of the exercise to Swansea). So in the flight plan I suggest 1hour and 50 minuttes, of course adjusted to allow for the actual airspeed of your aircraft.

Notes

1. NE is short for Navigation Exercise, NE01 is Navigation Exercise Waypoint 01 and so forth.
2. This flight is primarily outside controlled airspace.
3. Plan to fly at 4000ft msl if possble, because of terrain, but remain clear of cloud. That means below it, as "VFR on top" is not permitted in the UK! From NE05 to NE06 you should be very close to Cardiff airspace with a base of 4000ft, so make sure to go below, after NE08 you can safely climb to 4000ft again.
4. Some of the NE's are interesting or famous landmarks.

Weather Before starting we will check the weather. Please use VATSIM weather if at all possible for greater realism, and a more interesting challenge.
Note that the Maximum Elevation Figure (MEF) en route, is around 3000ft AMSL.
ATC At the time of publishing this event, ATC has not been confirmed. However, you may find that Gloucester Approach and/or Gloucester Tower is manned, plus Swansea Radio.
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.
