NOTE Where  there  is  excessive  gravel/debris  or the ramp is slippery, the pilot may consider starting   the   engines   with   the   props   in feather   and/or   ice   vanes   extended,   but must closely monitor ITT and oil temperature on engine start. c.   CONDITION levers – FUEL CUTOFF. d.   Trim tabs – Set. 9.   Lower console switches – Set. a.   Avionics – As required. b.   RUDDER BOOST switch – On. 10.  Gear ratchet handle – Stowed. 11.  Free air temperature gauge – Check. 12.  Pilot’s instrument panel – Check and set. a.   COMPASS control – SLAVE. b.   EFIS POWER – OFF. 13.  Copilot’s instrument panel – Check and set. a.   COMPASS control – SLAVE. 8A-22.  FIRST ENGINE START (BATTERY START). Starting     procedures     are     identical     for     both engines except the second engine generator is kept off line  after  the  second  engine  start  to  allow  performing the  current  limiters  check.    When  making  a  battery start,   the   right   engine   should   be   started   first.      A crewmember   should   monitor   the   outside    observer throughout the engine start. 1.   BATT switch – ON. 2.   EXTERIOR LIGHTS – As required. 3.   Propeller – Clear. 4.   Engine – Start. a.   IGNITION  AND  ENGINE  START  switch –   ON.      IGN   ON    annunciator   should illuminate  and  associated  FUEL  PRESS annunciator extinguished. CAUTION If ignition does not occur within 10 seconds    after    moving    the    condition lever to LOW IDLE initiate Engine Clearing procedure,   Paragraph   8A-25.      If   for   any reason the starting attempt is discontinued,  the  entire  starting  sequence must be repeated after allowing the engine to   come   to   a   complete   stop   (1-minute minimum). b.   CONDITION  lever  (after  N₁  stabilizes  at or above 12% for 5 seconds minimum) – LOW IDLE. CAUTION Monitor  ITT/TGT  to  avoid  a  hot  start.    If there is a rapid rise in ITT/TGT, be prepared to     abort     the     start     before     limits     are exceeded.    During  starting,  the  maximum allowable ITT/TGT is 1000 °C for 5 seconds. If  this  limit  is  exceeded,  discontinue  start and     use     the     Abort     Start     procedure, Paragraph     8A-24.          Record     the     peak temperature and duration on DA Form 2408-13-1. c.   ITT/TGT   and   N₁   –   Monitor.      ITT/TGT 1000 °C maximum.  N₁ minimum 56%. d.   Oil pressure – Check (60 psi minimum). e.   IGNITION  AND  ENGINE  START  switch – OFF after 50% N₁. 5.   Engine and systems instruments – Check.
