TM 55-1510-220-10 CAUTION Monitor TGT to avoid a hot start.  If there   is   a   rapid   rise   in   TGT,   be prepared  to  abort  the  start  before limits are exceeded.  During engine start,  the  maximum  allowable  TGT is 1000°  C  for  five  seconds.   If  this limit     is     exceeded,     use     ABORT START  procedure  and  discontinue start.    Enter  the  peak  temperature and duration on DA Form 2408-13. 7. TGT and N1 Monitor (TGT 1000°C maximum, N1 52% minimum). 8. Oil pressure Check (60 PSI minimum). 9. Ignition  and  engine  start  switch  OFF  after  50% N1. 10. Condition   lever   HI   IDLE.      Monitor   TGT   as   the condition lever is advanced. 11. DC GPU Disconnect as required. 12. Generator   switch   (GPU   disconnected)   RESET, then ON. 8-34.  * SECOND ENGINE START (GPU START). 1. Propeller Clear. 2. Ignition   and   engine   start   switch   ON.      Propeller should begin to rotate and associated #1 IGN ON or #2 IGN ON annunciator light should illuminate. Associated #1 FUEL PRESS or #2 FUEL PRESS annunciator light should extinguish. CAUTION If ignition does not occur within 10 seconds    after    moving    condition lever  to  LOW  IDLE,  initiate  engine clearing    procedure.        If    for    any reason a starting attempt is discontinued,    the    entire    starting sequence   must   be   repeated   after allowing  the  engine  to  come  to  a complete stop (5 minute minimum). 3. Condition    lever    (after    N1    RPM    passes    12% minimum) LOW IDLE. CAUTION Monitor TGT to avoid a hot start.  If there   is   a   rapid   rise   in   TGT,   be prepared  to  abort  the  start  before limits are exceeded.  During engine start,  the  maximum  allowable  TGT is 10000 C for five seconds.  If this limit     is     exceeded,     use     ABORT START  procedure  and  discontinue start.    Enter  the  peak  temperature and duration on DA Form 2408-13. 4. TGT and N1 Monitor (TGT 10000C maximum, N1 52% minimum). 5. Oil pressure Check (60 PSI minimum). 6. Ignition  and  engine  start  switch  OFF,  after  50% N1 7.  Propeller levers FEATHER. 8. GPU Disconnect.  (Check aircraft external power and mission external power light extinguished.) 9. Propeller levers HIGH RPM. 10. Aircraft inverter switches ON, check #1 INVERTER and #2 INVERTER annunciator lights extinguished. 11. Generator switches RESET, then ON. 12. Condition levers As required. 8-35.  BEFORE TAXIING. *1. Brake  deice  As  required.    To  activate  the  brake deice  system  proceed  as  follows:  a.    Bleed  air valves OPEN. b. Condition levers HI IDLE. c. Brake deice switch DEICE.  Check BRAKE DEICE ON advisory annunciator light illuminated. *2. Cabin temperature and mode Set. CAUTION Verify   airflow   is   present   from   aft cockpit   eyeball   outlets   to   insure sufficient cooling for mission equipment. 8-14
