Ottawa Intl airport procedures

Procedures

Airspace

Ottawa airport is a class C airport. The 7nm control zone (C) extends to 4000ft ASL.

The airport lies within the Ottawa TCA, which also covers Ottawa-Gatineau (CYND), Ottawa-Carp (CYRP) and many smaller uncontrolled airfields. The TCA extends to 13'000 and is class C, D and E transponder airspace below 12'500ft, then B above that.

The real-world shape is somewhat irregular, but we have rounded it out for IVAO use. Note the close proximity of the Gatineau and Rocliffe airports.

Noise abatement procedures

Noise abatement procedures exist at Ottawa during the day (0700-2300 local), as well as at night (2300-0700). Please see charts for complete noise abatement procedures.
Bear in mind all times are local (UTC -5/-4 in summer)

Clearance

An agreement has been set up between the airport and the TCU allowing the Clearance controller to issue IFR clearances without requesting them from Terminal. In this arrangement the prefix "ATC clears" will be dropped, as the clearance is not being relayed. Also the phrase "Clearance on request" should not be used, as this implies that you are waiting for someone to give you the clearance. If you have to delay the clearance use something along the lines of "Standby, I'll call you" .

To co-ordinate the smooth flow of aircraft away from departing airport area all departing aircraft must comply with the following routing restrictions.

Route / Clear direct	Direction	Route / Clear direct	Direction
YOW / YMW	North	YOW / REEDO V140	South
YOW V360	East / North-East	YOW / CELAR V300-308	West / South West
YRR dct LAFIT	East (MEA 5'000)	YOW / CELAR J546	West / South West
ULAMO / AVVON V300	East (MEA 10'000)	YOW / WRANG V316	South
ULAMO V104	East / South-East

Exits via LANRK, CYRIL, THURO, ABCOT are prohibited.

All IFR flights are to be cleared via the Ottawa 2 (O2) Standard Instrument departure

Squawk codes

Internal flights (flights remaining in the Montreal FIR): 4230-4237
External flights (flights leaving the Montreal FIR): 1060-1077
VFR Remaining within the Ottawa TCA: 0301-0377

Ground

Standard ground procedures apply.

Be alert to push backs on taxiways Bravo and Echo.

Tower

Runway configurations

All runways are available for arrival and departures, though 04/22 is only available to light aircraft due to it's length, and as it's unlighted it may not be used at night. Check favourable winds for assigning runway in use.

There are no "preferred" runway assignments, but when you select runways try and keep taxi time as well as type of approach in mind. For instance runway 14 and 25 have no ILS.
A pilot may request a different runway and the request should be approved unless it would create a conflict with other traffic.

Departures

A permanent agreement is in place with the Capital TCU which places the responsibility of ensuring the initial separation and release of IFR traffic with the Tower. The required radar wake turbulence separation minima must be ensured by the Tower controller and is described in MANOPS section 533.2. Besides providing the radar/wake turbulence separation between departures, the Tower controller must ensure that the initial separation between aircraft does not decrease. Factors such as aircraft performance and pilot technique vary even in the real world so be wary when attempting to run departures with minimum spacing, especially when departing a jet behind a prop, even if their wake category are the same.

During the day, props may be issued a turn off a SID by the Tower controller from runway 07, 25 and 32. The significance of this exemption is that by turning a Prop aircraft on departure, it allows subsequent departures to be expedited. The procedure is described in MANOPS section 554.1. No prior co-ordination with the Terminal controller is required provided the aircraft are always turned to a heading +/- 30° of runway heading All turns must be made to the south on runways 07/25. Remember to update the datatag if using this procedure with the assigned heading instead of the SID identifier, as described in the Clearance SOP.
On Departure IFR traffic is handed to "Ottawa Departures" with the take-off clearance.

Arrivals

Though it is a responsibility of the Arrival controller to provide the appropriate separation between successive arrivals on final approach, responsibility for spacing between arriving aircraft is transferred to the Tower automatically once the aircraft crosses the Final Approach Fix (FAF).
With the use of radar the Tower assumes control of arrivals at the FAF regardless of the weather conditions. See MANOPS section 362.5 for the proper control transfer procedures.

If using IvAi in conjunction with FS to operate a visual tower viewpoint you may decrease the 3 nm separation of aircraft on final provided both aircraft are in sight. Aircraft conducting visual approaches in accordance with MANOPS section 566 and 567 are responsible for maintaining their own separation.

On Arrival traffic will be handed off to Tower once established on the approach, at or slightly before the FAF.

VFR traffic

Arrivals
VFR traffic will be transferred to tower prior to entering the control zone.

Departures
Assign a maximum altitude of 3,000 feet to all VFR departures. A higher altitude may be requested from Terminal.

Aircraft going to Gatineau will be transferred directly to the Gatineau FSS.
