| * All aircraft should be retrieved quickly from the airfield to keep landing areas clear (particularly the South Field and the aerotow strip) and increase launch efficiency; the retrieve team and vehicle should be ready to go as soon as a glider lands or even better, in anticipation of its landing. The PIC remains responsible for the glider until it is handed over to the next PIC or parked up on- or off-line.

| - | Gliders should be towed back to the launch point according to the diagrams below – do not try and tow the glider directly into the launch queue with a buggy. Please use the tail dolly when towing the DG505 (or any other heavy-tailed glider) to avoid putting unnecessary stress on the glider when turning. Please push the nose down slightly on a K21 when turning to unload the tailwheel. | + | ===== 5.10 Ground operations ===== |

| When parking up gliders place them well to the rear of the launch point keeping a through-route for other gliders and aircraft. Turn them so they get a quartering tailwind. In strong winds all gliders should be parked with the into-wind wing securely weighted with one or more tyres, a tyre wedging the nose and another on the downwind side by the tail. In lighter winds two seaters (which are heavier) may be parked with the into-wind wing up and tyres at nose and tail. Switch off the electrics, lock the canopy and close the vents. Watch for control surfaces gybeing and slamming onto the stops in strong winds. | When parking up gliders place them well to the rear of the launch point keeping a through-route for other gliders and aircraft.

The gliders will need cleaning to remove mud from the underside, insects, and the like – use either the cleaning station adjacent to Clubhouse or the one by the club hangar. If the gliders are wet from rain, etc. then please squeegee them dry especially in winter as the water may end up freezing on the wings overnight. | Gliders can be progressively put away as they are no longer needed.

| Please note that “Portmoak Base” is an unofficial station and cannot issue clearances or specific aeronautical information such as QFE/QNH. Airfield information that can be given to passing aircraft or joining gliders is purely for situational awareness, e.g. “winch launching to the West from the Centre Strip, multiple gliders active in the area”. A plain English wind direction and strength can also be given to joining aircraft if requested. The predominant circuit direction and runway in use may be a useful aid to safety. | Please note that “Portmoak Base” is an unofficial station and cannot issue clearances or specific aeronautical information such as QFE/QNH.

The key point is that Flarm is a supplement to your visual scan and not a substitute for it. Furthermore do not assume that all gliders have Flarm. | + | Flarm can be a very effective supplement to a good look-out; it helps improve situational awareness of gliders particularly in blind spots. |
| Note that Flarm works on track, not heading, and may give confusing indications of direction for hill-soaring gliders crabbing along the ridge or a wave bar. If you get a Flarm alert the key thing to do is **look out**, especially ahead and either side of the nose, and not to look at the instrument. | Note that Flarm works on track, not heading, and may give confusing indications of direction for hill-soaring gliders crabbing along the ridge or a wave bar.
