5.7.1. Objective. Maintain proper spacing and a ground track parallel to the runway. Apply drift correction and offset inside/closed downwind ground track into the wind to account for the effects of wind on the final turn. Arrive at perch point at 120 KIAS minimum, properly configured, trimmed, and ready to perform a planned 30-degree bank final turn.
p. 64
5.7.2. Description. Airspeed - 120 KIAS minimum or according to local directives. (T-2)

5.7.3. Procedures. (T-2)
p. 64
5.7.3.1. On inside/closed downwind, 10-20% torque will smoothly slow the aircraft until ready to configure. Lower power may be required if airspeed at level off is higher than anticipated and/or distance to begin configuring prior to the perch is becoming compressed. Zero torque (idle) may be used if the pilot determines airspeed is excessive but should only be used momentarily due to the higher drag and time to spool the engine back up to hold safe airspeed.
p. 64
5.7.3.2. When airspeed is below 150 KIAS, make an intercockpit “gear clear” call and pause momentarily before moving the gear handle. On student pre-solo sorties, the IP must acknowledge the “gear clear” call with “clear” before the student pilot lowers the gear. On all other sorties, “gear clear” is an advisory call only.
p. 64
5.7.3.3. Lower the landing gear and flaps as required. As the flaps are lowered, the nose of the aircraft pitches up slightly due to the increase in lift. Maintain level flight by slightly increasing forward control stick pressure and trim for zero control stick forces. The objective is to be trimmed-up, hands-off as described in paragraph 2.9.1.4.
p. 65
5.7.3.4. Adjust power between approximately 30% – 45% depending upon flap setting to maintain airspeed (120 KIAS minimum) and pattern altitude.
p. 65
5.7.3.5. Adjust spacing and perch point for winds. No wind spacing is approximately 0.7- 1.0 mile. Drift correction is approximately twice the correction used on initial. Visual references are given in Table 5.1.
p. 65
5.7.3.6. PF verbally confirms completion of Before Landing checklist. PNF physically checks the gear handle down and acknowledges the aircraft configuration IAW T.O. 1T-6A-1 and local directives.
p. 65
5.7.4. Techniques. Upon arrival on inside downwind, common techniques to arrive at the perch are the memory devices “3 S’s” or “4 T’s.
p. 65
5.7.4.1. 3 S’s:
p. 65
5.7.4.1.1. S – Speed – approximately 10-20% torque and maintain min 120 KIAS.
p. 65
5.7.4.1.2. S – Spacing – adjust pattern ground track for wind correction.
p. 65
5.7.4.1.3. S – Speak -make appropriate radio call.
p. 65
5.7.4.2. 4 T’s:
p. 65
5.7.4.2.1. T – Torque: approximately 10-20% (or as required to maintain min 120 KIAS)
p. 65
5.7.4.2.2. T– Track: adjust pattern ground track for wind correction.
p. 65
5.7.4.2.3. T – Talk: make appropriate radio call.
p. 65
5.7.4.2.4. T – Trim: trim off control pressure as airspeed decays.
