1. Circuit Patterns

Powered aircraft are required to circuit South of the airfield. Gliders are required to circuit to the North of the site. This means that when operating on Runway 27, gliders will be on a right-hand circuit and when on Runway 09, a left-hand circuit.

Visiting powered aircraft unfamiliar with Shobdon may descend to the North of the airfield to around 1000 feet QFE before crossing overhead to the circuit on the South. Therefore, if you are to the North of the airfield at 1000 to 2000 feet, watch out particularly for descending powered aircraft. Avoid circling inside a line drawn between the brickyard at the West end of the field and the village.

The normal powered aircraft circuit is shown on the map here. Stay clear of this area below 1500 feet QFE when local soaring. If you are returning low to the site, inform the tower on 123.5MHz. Remember to keep a good lookout, especially since the visibility from the inside of many power aircraft is very limited.

A square pattern is mandatory and a dim view is taken of unorthodox approaches, which may lead to confusion with other airfield users. Aerobatics or racing finishes are prohibited unless clearance has been obtained from the tower.

2. Landing Areas

On Runway 27R: Normally, landings are made on the grass area marked on the above map and cleared to the left. During the winter, avoid landing within the first 50m since it is likely to be waterlogged and not capable of supporting traffic. If the grass is congested, landings may be made on runway 27, but only after contacting the tower on 123.5Mhz (see Radio below). DO NOT STOP in the middle of either runway, there is always following traffic.

The Eastern edge of the airfield is bounded by a perimeter road and a one metre high heavy wooden post fence. NEVER approach LOW over this fence, as there may be turbulence and/or heavy sink, especially in Northwesterly winds. 27R is about three field lengths and so there is little chance of over-shooting it.

On Runway 09L and 09: Landings may be on either runway after contacting the tower. On the grass area 09L, gliders should clear to the right after 75m, which will avoid the earth ridge between the grass and the paved area. Large span gliders of 18m or more should use 09 when standing crops are in the adjacent field. Landings on 09 should be made short on the centreline and cleared to the left. It is important that gliders DO NOT STOP in the middle of either runway, there is always following traffic.

The Western end of the landing strips are bounded with a wire fence which has RED conspicuity markers attached. The area between the boundary and this fence contains debris from farm sales and should not be used, except in an emergency. Tugs or gliders are to be parked to the North of the resurfaced section. Hanger flights, the landings can be made on the same grass area normally used when operating on 27R provided that the instructor in charge agrees on the day and the tower has been informed.


3. Powered Aircraft Taxi Areas

These are marked on the above map. The taxiway to Runway 09 should not offer any problems as it is between two cropped sections of the airfield. The taxiway from Runway 27 however is approximately midway along the grass area. Although gliders will normally have stopped by this point, it is worth watching carefully for any powered aircraft failing to look before crossing the grass landing area. When operating on 09, gliders being towed from the trailer park must tow out on the Southern side of Runway 27 (on the rough) taking great care when crossing the approaches.

4. Motor Gliders

All motor gliders operating at Shobdon are to be treated as gliders i.e. you have no priority over them. Motor gliders being flown as powered aircraft are to obey the rules for powered aircraft i.e. fly the powered circuit and give way to gliding traffic.

5. Radio

Shobdon powered aircraft are operating on a frequency of 123.5MHz. Gliders are expected to report their position in the circuit to the tower on this frequency. Normal calls (operating on 27) would be:-

  • High key "Glider xxx downwind for 27R grass"
  • Base leg "Glider xxx base leg"
  • Approach "Glider xxx finals"

6. Airfield Access

  • Cars are permitted on the North side peri-track but care must be taken because power aircraft, who have priority, may be crossing between the hangers/pumps and the grass. When helicopter refuelling with Avgas is taking place, the fuel line will be laid across the peri-track and you must not drive across it under any circumstances. Normally, a warning board will be placed on the track.

  • The glider trailer park is at the East end of airfield and gliders may be rigged on the trailer i.e. Cobra style or on the grass area opposite, but note that this part of the perimeter track may have a high volume of farm vehicular traffic. Visiting owners of very large span gliders 22m plus which have to be rigged on their trailers should use the stub of the peri-track on the South side of 27. The C.A.A. have imposed strict rules on the proximity of items to the runway. Therefore ensure that your trailer is parked as far away as possible from the edge of the surfaced area and runway threshold. If in doubt, ask the duty instructor.

  • Cars may tow gliders to the launch point situated on the rough ground North of runway 27, remember that when you cross 27R (grass) it is active and you must maintain a good lookout. One car only may be left at the launch point; all other cars must be removed to the North and clear of the landing and rigging area. During the winter the grass threshold of 27R is very soft and some areas are not capable of supporting the weight of gliders or cars. Get advice from the duty instructor.

  • When operating on 09, gliders may be towed from the trailer park to the launch point in the rough ground area. North of runway O9 via the rough area immediately to the South of the main runway, remember that when you cross runways 27R and 27 to the South side they are active and you must maintain a very good lookout. One car only may be left at the launch point; all other cars must be removed to the South side of the surfaced runway 09, in the parking area as shown on map.

  • Access to and from the launch point 09 by car or on foot is via the North side peri-track. Be aware that the power aircraft taxiway joins from the active side approximately level with the airfield main access road Give way to power. To reach the parking area you will have to cross 09L and 09 thresholds, which will be active.

  • Occasionally when operating on 09, trailers have been towed down the North side peri-track to the parking area situated on the South side of 09 and the glider rigged on the rough ground. You are requested to remove the trailer back to the trailer park before commencing flying. The C.A.A. have imposed strict rules on the proximity of items to the runway, therefore ensure that your trailer is parked as far away as possible from the edge of the surfaced area and runway threshold. Do not obstruct other people parking.

    8. Cloud Flying

    Because of the volume of power flying, no cloud flying is permitted within 5 nautical miles of the site unless a call is first made on 123.5MHz (using l30.4MHz alone is not acceptable) giving exact position and height AMSL. You must then maintain a listening watch on the airfield frequency.

    9. Military Activity

    There is an increasing amount of military low-level flying these days especially midweek - KEEP A GOOD LOOKOUT AT ALL TIMES. Occasionally the airfield will be used as a target, but always with the prior permission of the airfield manager. Notice of these events are posted on the information board in the Aero club on the morning in question, giving time, type and number of aircraft. Do not rely on the duty instructor to pass on this information, but make it a habit of checking the information board yourself. Gliders in transit may receive details transmitted by the military aircraft on Shobdon tower frequency but do not expect warning transmissions on 130.1MHz.

    10. Airfield Rules

    You are advised to read the Aero Club FLYING ORDERS even if you only fly gliders, remember there are other users of the airfield with differing requirements. This airfield can be busy, especially at weekends, and the flying activities may be considerably more intense and varied than you are likely to experience at other sites. So be prepared to THINK AHEAD of all the eventualities BEFORE FLYING and do ask the duty instructor if you are unsure of anything. Ample good fields are available if a rope-break should necessitate an out landing. If an abbreviated circuit should be necessary, then aim to keep the whole manoeuvre clear of all powered traffic. THINK about this before flying rather than when it happens, you may not have sufficient thinking time available at a few hundred feet. Downwind landings are high risk and on an active airfield, can be extremely dangerous.
