TM   55-1510-219-10 Section   VIII.   OTHER   LIMITATIONS 5-35. INSTRUMENT LANDING SYSTEM LIMITS. During  ILS  approach  do  not  operate  the  propel- lers  in  the  1750  to  1850  RPM  range. 5-36.  FERRY  CHAIR. A  ferry  chair  may  be  installed  in  the  cabin  area for   use   on   ferry   missions.   The   seat   may   be   installed in  the  forward  or  the  aft  facing  positions.  The  side  facing lavatory  is  limited  to  170  pounds. 5-37.   INTENTIONAL   ENGINE   CUT   SPEED. Inflight  engine  cuts  below  the  safe  one-engine  in- operative  speed  (V_sse  -  104  KIAS)  are  prohibited. 5-38.   RADOME   ANTI-ICE   OPERATION. The  following  limitations  apply  to  operation  of the   radome   anti-ice   system: N O T E Ice  accumulation  on  the  forward  data  link randome  does  not  adversely  affect  the  fly- ing   qualities   of   the   aircraft,   however   ice accumulation  does  affect  the  data  link  op- eration.   Therefore   radome   anti-ice   should be  used  only  in  conjunction  with  the  mis- sion   equipment. 1. Radome  anti-ice  shall  be  off  during  takeoff, landing,  and  any  single  engine  operations. 2. Maintain   85%   N₁   or   above   during   simulta- neous  operation  of  the  radome  anti-ice, brake  deice,  and  surface  deice  systems.  If  ad- equate   pneumatic   pressure   cannot   be   pro- vided   for   simultaneous   operation   of   these systems,   turn   off   the   radome   anti-ice   and brake  deice  systems. 5-39.  CABIN  DOOR. The  cabin  door  is  weight  limited  to  300  pounds to   prevent   possible   structural   damage. 5-40.  MAXIMUM  DESIGN  SINK  RATE. The  maximum  design  sink  rate  below  13,500 pounds   gross   weight   is   600   feet   per   minute.   The maximum  design  sink  rate  above  13,500  pounds gross   weight   is   500   feet   per   minute. Section  IX.  REQUIRED  EQUIPMENT  FOR  VARIOUS  CONDITIONS  OF  FLIGHT 5-41.  REQUIRED  EQUIPMENT  LISTING a. A   Required   Equipment   for   Various   Condi- tions  of  Right  (table  5-3)  is  provided  to  enable  the pilot   to   identify   those   systems/components   required for   flight.   For   the   sake   of   brevity,   the   listing   does not  include  obviously  required  items  such  as  wings, rudder,   flaps,   engines,   landing   gear,   etc.   The   list   also does   not   include   items   which   do   not   affect   the   air- worthiness  of  the  aircraft  such  as  galley  equipment, entertainment   systems,   passenger   convenience items,   etc.   It   is,   however,   important   to   note   the   ALL ITEMS   WHICH   ARE   RELATED   TO   THAT   AIR- WORTHINESS   OF   THE   AIRCRAFT   AND   NOT INCLUDED   ON   THE   LIST   ARE   AUTOMATI- CALLY  REQUIRED  TO  BE  OPERATIVE b. It  is  the  final  responsibility  of  the  pilot  to determine   whether   the   lack   or   inoperative   status   of a   piece   of   equipment   on   the   aircraft   will   limit   the conditions   under   which   the   aircraft   may   be   operat- ed. (-)Indicates   item   may   be   inoperative   for   the specified   Right   condition. (*)Refers   to   remarks   and/or   exceptions   column for   explicit   information   or   reference. Numbered  items  contained  in  (  )  are  required for   flights   by   AR   95-1. c. The   pilot   is   responsible   for   exercising   the necessary   operational   control   to   assure   that   no   air- craft  is  flown  with  multiple  items  inoperative,  with- out   first   determining   that   any   interface   or   interrela- tionship  between  inoperative  systems  or  components will  not  result  in  a  degradation  in  the  level  of  safety and/or  cause  an  undue  increase  in  crew  workload. d. The   exposure   to   additional   failures   during continued   operation   with   inoperative   systems   or components   must   also   be   considered   in   determining that   an   acceptable   level   of   safety   is   being   main- tained.  The  REL  may  not  deviate  from  requirements of   the   operators   manual   limitations   section   emer- gency  procedures  or  safety  of  flight  messages. 5-10 C h a n g e    2
