MATLAB在飞行动力学和控制中应用的工具

-----------------------------------------------------------------
The masked subsystem block ILSTEST, from the sublibrary ILS of
the library NAVLIB, is called from within the masked Simulink
block ILS, in order to check if the localizer and glideslope
signals are valid at the position of the aircraft.

Inputvector: utst.
==================
  utst = [Gamma_loc Gamma_gs Rloc Rgs]'.

where:

  Gamma_loc: 2D-angle between line from c.g. of aircraft to lo-
             calizer antenna and runway center-line (as seen from
             above), [rad]
  Gamma_gs : 2D-angle between line from c.g. of aircraft to
             glideslope antenna and runway center-line (as seen
             from above), [rad]
  Rloc     : 2D-distance from aircraft's c.g. to localizer antenna
             (as seen from above), [m]
  Rgs      : 2D-distance from aircraft's c.g. to glideslope anten-
             na (as seen from above), [m]

Outputvector: yils4.
====================
  yils4 = [LOCflag GSflag]'.

  GSflag = 0 if aircraft is in area where glideslope signals can
  be received with appropriate accuracy LOCflag = 0 if the air-
  craft flies in area where the localizer signals are receivable.
  If the aircraft is too far away, GSflag = 1 and/or LOCflag = 1!
