It is common for soaring conditions to be favourable during calm, West or Northwest wind conditions. In all of these cases it can be expected that Ottawa Intl will be using runway 25 and 32 for arriving and departing aircraft. As such, the VNC chart has overlays only for Rwy 25 and 32. Reference can be made to the actual STAR Cyril 6 chart for Rwy 07 and 14.
The STAR Cyril 6 is a common arrival routing into Ottawa Intl from the South for non-FMS equipped aircraft, such as B737-200 or Dash-8. This STAR services all of the runways and has a common routing up to the CYRIL intersection, at which point headings and/or vectors will be assigned to the arriving aircraft depending on the runway assigned.
If an aircraft were to remain on this arrival routing, the closest point of proximity to the centre of Pendleton Airport not be any factor to local traffic.

Sailplanes are not necessarily seen on ATC radar. ATC may have no awareness of your presence! If you are seen on ATC radar, the raw radar returns from a sailplane are often confused as a flock of birds. It is always considered to be superior airmanship to use the radio to contact the Ottawa TCA periodically to inform them of your position, altitude and intentions should you be approaching any airspace boundary or if you suspect you may be a potential conflict for other aircraft.
Arriving aircraft may be cleared to as low as 3000' when North of the CYRIL intersection when landing on Rwy 32! This will result in IFR aircraft flying across common cross-country soaring corridors at typical soaring altitudes.
Arriving aircraft are typically cleared to approximately 6000' when North of the CYRIL intersection when landing on Rwy 25. This may result in IFR aircraft flying across common cross-country soaring corridors within soaring altitudes.
For aircraft arriving from the South, it is possible to see aircraft that have been cleared direct the TEXAN or TEFLY intersections when landing on runway 32 or 25 respectively at any time, therefore may not be following the exact tracks depicted by the STAR Cyril 6.
The transitions from Watertown or Massena are not necessarily part of the Cyril 6.
