 Symmetrical Autopilot modes.
 ============================
 Subsystem of APILOT1, APILOT2, or APILOT3.

 The 'Beaver' autopilot contains the following symmetrical con-
 trol modes:

 *  Pitch Attitude Hold (PAH), including turn compensation
 *  Altitude Hold (ALH), including turn compensation
 *  Altitude Select (ALS)
 *  symmetrical approach mode: Glideslope (GS)

 The PAH mode is also used as inner-loop for ALH, ALS, and GS.

 In Glideslope mode, a switch criterion is used to switch from
 the Glideslope-Armed phase, in which the aircraft is usually
 flying under ALH control, to Glideslope-Coupled. Note: for rea-
 sons of computing speed, GS is not included in the system
 APILOT1.

 The block 'Select symm. mode-controller signals' separates the
 mode-switch settings and reference signals for the symmetrical
 autopilot modes from the asymmetrical mode-switch settings and
 reference signals.

 More info
 =========
 See the .HLP file APILOT for more details about the complete
 autopilot simulation systems APILOT1, APILOT2, and APILOT3. The
 .HLP files MODECTRL and REFSGNLS give more info about the blocks
 'Mode Controller' and 'Reference Signals'; AP_ASYMM.HLP gives
 details about the asymmetrical autopilot modes.
