Hint 2

Speed

Front 3

What are the provisos for T1, 45°? 2.

Back 3

Hint 3

Tracks

Front 4

What are the provisos for T1, 45°? 3.

Back 4

Where the leading aircraft is to turn more than 90° action must be taken to ensure the departure track of the following aircraft does not cross the departure track of the leading aircraft.

Hint 4

Turn

Front 5

What are the provisos for T1, 45°? 4.

Back 5

May be used when the leading aircraft is slower provided the leading aircraft reports established on a track that diverges by at least 45° from the track of the following, prior to the following aircraft being cleared for take off.

Hint 5

Slower first

Front 6

What are the provisos for T1, 45°? 5.

Back 6

T1 shall not be used where both aircraft are to turn in the same direction and the angle of turn of the following aircraft is greater than the angle of turn of the leading aircraft.

Hint 6

Same direction turn

Front 7

What are the provisos for using T2, 40kt? 1.

Back 7

The leading aircraft will maintain a speed of 40 knots or more faster than the following aircraft.

Hint 7

Speed

Front 8

What are the provisos for using T2, 40kt? 2.

Back 8

Both aircraft propose to follow the same exact track or tracks that diverge by less than 45°.

Hint 8

Tracks

Front 9

What are the provisos for using T5, higher level? 1.

Back 9

T5 while vertical separation does not exist if a departing aircraft will be flown through the level of a preceding departing aircraft.

Front 10

What are the provisos for using T5, higher level? 2.

Back 10

Both aircraft propose to follow the same exact track or tracks that diverge by less than 45°.

Hint 10

Tracks

Front 11

What are the provisos for using T5, higher level? 3.

Back 11

Action must be taken to ensure that T5 is maintained or increased while vertical separation does not exist.

Hint 11

Action

Front 12

30° successive departure separation, leading aircraft same speed or faster, provisos. 1.

Back 12

Initial departure tracks diverge by 30° or more; and

Hint 12

Initial tracks

Front 13

30° successive departure separation, leading aircraft same speed or faster, provisos. 2.

Back 13

Visual or radar observation confirms that:

• the leading aircraft has turned to clear the proposed departure track of the following aircraft and adequate separation will exist, or
• the leading aircraft has reached a point where adequate separation will exist with the following aircraft; and

Hint 13

Observation

Front 14

30° successive departure separation, leading aircraft same speed or faster, provisos. 3.

Back 14

The aircraft tracks will continue to diverge by 30° or more until some other form of separation exists; and

Hint 14

Continuing tracks

Front 15

30° successive departure separation, leading aircraft same speed or faster, provisos. 4.

Back 15

Aircraft performance, including the radius of turn of the following aircraft, is taken into account when applying the separation; and

Hint 15

Aircraft performance

Front 16

30° successive departure separation, leading aircraft same speed or faster, provisos. 5.

Back 16

Meteorological conditions, including wind direction and strength, are taken into account when applying this separation; and

Hint 16

Meteorological conditions

Front 17

30° successive departure separation, leading aircraft same speed or faster, provisos. 6.

Back 17

Where necessary, traffic information is passed to the following aircraft.
