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 River 3 charts for Rwy 07 and 14.
The STAR River 3 is a common arrival routing into Ottawa Intl from the East for FMS equipped aircraft, such as B767 or Airbus A320. This STAR services all of the runways and has a common routing up to the AGLIN intersection, at which point arriving aircraft fly to runway-specific intersections 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 would be 2 nautical miles north of the airfield.
River Arrival - All Rwys
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 approaching the AGLIN intersection when landing on Rwy 25! This will potentially result in IFR aircraft flying through Pendleton's proximity within soaring altitudes.
Ottawa TCA assumes control of inbound IFR aircraft prior to the AGLIN intersection but typically not before the THURO intersection. Should an IFR aircraft request to be cleared directly to an approach fix for a particular runway (ie. direct TEXAN for runway 32) while still with Montreal Centre control, Montreal Centre first must ask Ottawa TCA. Ottawa TCA will only approve clearing an aircraft directly to an intersection if there is no known traffic.
For aircraft arriving on runway 32, it is possible to see aircraft that have been cleared direct the TEXAN intersection when landing on runway 32 at any time inside the THURO intersection! Potential for collision exists with Pendleton local traffic during VFR conditions if Ottawa TCA is unaware of Pendleton operations!
