TM 1-1520-238-10 8-12 Change 8 *8.18. AFTER STARTING APU – CPG. 1. Control locks – Remove. 2. Canopy door – Secure. 3. Avionics – As desired. 4. ADSS switch – On. 5. FC SYM GEN switch – As required. 6. IHADSS switch – As required (Announce to pi- lot). NOTE Do not turn the SYSTEM TADS/FLIROFF/ OFF switch to TADS immediately after being set to OFF. Damage to the TADS power supply could result. 7. TADS switch – As required (Announce to pilot). NOTE If an erroneous magnetic variation is en- tered, the compass card in the HSI will give erroneous readings. 8. Fire control system – Enter data/interrogate as desired for: a. PPOS. (Announce to pilot when present position has been entered.) b. Waypoint/target data. c. Laser codes. NOTE Steps 9 thru 15 may be performed in any or- der. 9. IHADSS boresight – As required. 10. Doppler – Program as desired. 11. TADS operational checks – As required. 12. TADS internal boresight – As required. 13. TADS outfront boresight – As required. 14. FLIR operational check – As required. 15. Weapons Systems – As desired. *8.19. BEFORE STARTING ENGINES – PILOT. 1. SHAFT DRIVEN COMP caution light – Extin- guished. Verify ECS airflow from crew station vents. 2. ANTI COL switch – As desired. *8.20. STARTING ENGINES – PILOT. WARNING Aborted engine starts may cause fuel to collect in the engine nacelle. Sub- sequent engine starts may be attempted only after the nacelle door/work platform is opened and the nacelle inspected for fuel. If during the initial start an abnormal TGT rise was evident, or fuel is evident in the nacelle, the ignition system shall be checked IAW standard maintenance pro- cedures. CAUTION During a start with RTR BK switch set to LOCK, if rotor blades begin to ro- tate, set RTR BK switch to OFF. The T700–GE–701C engine exhibits inconsistent starting capability above 6000 feet density altitude. Starts above this density altitude may be un- successful and require “over tempera- ture” abort by the pilot. 1. Area – Clear. 2. RTR BK switch – OFF or LOCK. NOTE Use the procedures in para 3.a. thru 3.e. for COLD and WARM -701 engine starts and for COLD -701C engine starts (more than 4 hours since last shutdown) and all INFLIGHT and engine starts. Use the procedures in para 3.f.(1) thru 3.f.(4) for WARM engine starts on the GROUND. 3. First engine – Start as follows: a. START switch – START. b. PWR lever – IDLE after N_G speed increases and TGT is below 150 C . c. ENG OIL pressure gauge – Monitor. d. TGT gauge – Monitor. e. N_G gauge – Monitor.
