If the turn in track is between 31 and 40 degrees, the turning point must be defined as a radio navigation aid, or radar must be used to observe the turn and ensure the departure standard does not decrease until the aircraft is established on the new track.
Dep 7/7A                             Following aircraft climbing to the same level.             1. Both aircraft report reaching the cruising level;

                                                                                                3. CLIAS of the second aircraft is less than or equal to the CLIAS of the first aircraft.
Dep 8                                Faster following aircraft climbing to higher level.        1. Only useable when the first aircraft has reached 5,000 FT or above;
Distance Determined by Speed                                                                    2. The vertical difference between the aircraft must be used to determine the appropriate distance required between the aircraft. This distance must be subtracted from the DME distance of the leading aircraft (see table);
                                                                                                3. The following aircraft must be instructed to reach 1,000 FT above the leading aircraft's cruising or maintain level, by the DME distance determined at 2;
                                                                                                4. Where both aircraft are airborne, the DME distance and levels of both aircraft must be required. Otherwise, only that of the leading aircraft is required; and
                                                                                                5. When the procedure is applied to a following aircraft that has not departed, the requirement must be updated once that aircraft has departed.

An F50 climbing to FL160 reports 50DME; an A320 ready for departure is required to reach FL 170 by 45 DME. After departing, the A320 reports 7,000 FT at 9 DME and the F50 65 DME, cruising FL160; the A320 may be given an updated requirement to reach FL170 by 55 DME.
                                                                                                2. A DHC8 reports cruising 9,000 FT at 30 DME. A B737 just departed is required to reach 10,000 FT on climb to FL250 by 20 DME.
                                                                                                3. An F50 climbing to FL180 reports 45 DME and is maintained at FL130. A B737 after departing and climbing through 4,000 FT is required to reach FL140 by 35 DME.
                                                                                                4. A C130 climbing to FL230 reports at 45 TACAN leaving 10,000 FT. An F18 ready for departure
