somewhat similar to the FAA’s “Diverse Departure.” It is a departure procedure without
any track guidance provided. There are some very important differences, though,
because an Omnidirectional Departure may be published even though obstacles penetrate
the 40:1 Obstacle Identification Surface. If this is the case, PANS-OPS gives the
departure designer a number of ways to publish departure restrictions. These restrictions
may be published singly, or in any combination.
18.3.4.1. Standard case. Where no obstacles penetrate the 40:1 OIS, then no
departure restrictions will be published. Upon reaching 400 feet above DER, you may
turn in any direction.
18.3.4.2. Specified turn altitude. The procedure may specify a 3.3% climb to an
altitude where a safe omnidirectional turn can be made.
18.3.4.3. Specified climb gradient. The procedure may specify a minimum climb
gradient of more than 3.3% to an altitude before turns are permitted.
18.3.4.4. Sector departure. The procedure may identify sectors for which either a
minimum turn altitude or a minimum climb gradient is specified. (For example,
“Climb straight ahead to 2000 feet before commencing a turn to the east/sector 180°-
270°).
18.3.5. Departures with Track Guidance (SIDs). PANS-OPS uses the term Standard
Instrument Departure (SID) to refer to departures using track guidance. Minimum climb
gradients may apply. There are two basic types: straight and turning.
18.3.5.1. Straight departures. Whenever possible, a straight departure will be
specified. A departure is considered “straight” if the track is aligned within 15° of the
runway centerline.
18.3.5.2. Turning departures. Where a departure route requires a turn of more than
15°, a turning departure may be constructed. Turns may be specified at an
altitude/height, at a fix or at a facility. If an obstacle prohibits turning before the
departure end of the runway or prior to reaching an altitude/height, an earliest turning
point or a minimum turning altitude/height will be specified. When it is necessary,
after a turn, to fly a heading to intercept a specified radial/bearing, the procedure will
specify the turning point, the track to be made good and the radial/bearing to be
intercepted.
18.3.5.2.1. Turning departures are designed with maximum speed limits. These
maximum speeds may be published by category or by a note. For example, these
procedures may be annotated, “Departure limited to CAT C Aircraft” or
“Departure turn limited to 220 KIAS maximum.” You must comply with the
speed limit published on the departure to remain within protected airspace. If
you require a higher speed, ATC may approve the higher speed or assign an
alternative departure procedure.
18.3.5.2.2. If the departure is limited to specific aircraft categories, these are the
applicable speeds:
