767 FSX features & FSX information

FMC
- FIXED descent path wrong when a conditional waypoint was the end of idle descent.
- FIXED AT was not holding speed in VNAV PATH approach submode.
- FIXED descent restriction alt wasn't being considered in some cases.
- FIXED hard alt restrictions on runway extension points caused incorrect descent profile.
- FIXED consecutive duplicate alt restrictions would caused incorrect prediction of T/D.
- FIXED all waypoints were sometimes wiped out when selecting rwy then star.
- FIXED MCP alt can now be set above aircraft alt when in VNAV Approach mode. (enables setting of missed approach altitude during a VNAV approach)

MISC
- FIXED clock chrono timer incorrectly restored with situation.
- FIXED Speed trend vector sometimes inop.
- FIXED issues with the Level-D menu items display.
- CHANGED the "please wait while engines start ..." textbox by an FS-style line text.
- CHANGED Engravity driver removed from standard gauge. Engravity users must now download alternate gauge from website.
- CHANGED the ground request menu has been replaced by an FSX ATC-style dialog box.
- NEW GPWS Glideslope audible warning rate modified based on altitude.
- NEW a new dialog box for importing the proposed fuel from the 767 Configuration Manager Load Sheet has been added.

MODEL
[Exterior]
- FIXED engine fan animation (Since fan animation is alway idle).
- FIXED spoilers deploy timing  when touch down (Previous mdl's spoiler deploy when aircraft is bit floating).
- FIXED deleted antennas shadow on the fuselage because SATcom anttena shadow will appear on the no satcom model fuselage.
- CHANGED LVLD_strobe.fx to avoid double flash of the default strobe effect.
- NEW nosewheel movement synced with fs2crew tiller.
 
[Interior]
- FIXED daytime overhead illumination resolution and brightness.
- FIXED windshield bloom effect removed.

767-SP2 for FSX Service Pack 2 (release 1.4.2):

FMC
- FIXED hard alt restrictions near destination would cause error in descent profile under certain conditions.
- FIXED FMC would ignore waypoint alt restrictions in the climb when the climb phase covered a very long distance.
- FIXED saving "STAR to runway transitions" in the FMC was inoperative.
- NEW added code to avoid saving destination runway as part of STAR-Runway transitions
- NEW added code to compensate for missing runway and vectors waypoint altitudes in XML procedure files.

MISC
- FIXED MCP altitude was not being honoured during VNAV approach submode
- NEW added depiction of vectors legs to EHSI
- NEW FSUIPC no longer required for the Level-D software.

FOR ENGRAVITY CDU USERS
- Look in the Gauges\LVLD folder in FSX for an alternate B767at.gau file in FSX_Engravity_Driver_1.4.2.zip. Simply unzip it to the same location overwriting the current gauge.

767-SP2a for FSX Service Pack 2a (release 1.4.2a):

- FIXED Pushback dialog not displayed in full screen mode
- FIXED "About box" now displays "release 1.4.2a"
- NEW added an "abort" option in ground request menu

VNAV descent logic for PEGASUS FMC

ON Path
 within speed limits and alt limits
  Pitch mode = VNAV PTH; AT mode = throttle drops to IDLE, then enters HOLD
  idle descent phase Speed limits +/- 15 knots, up to Mmo/Vmo-11 knots or down to speed protection
  past idle phase    Speed limits +/- 10 knots, up to Mmo/Vmo-11 knots or down to speed protection

 overspeed reverts to:
  Pitch mode = VNAV SPD; AT mode = IDLE to HOLD, aircraft pitches to VNAV speed
  DRAG_REQUIRED message

 underspeed reverts to:
  Pitch mode = VNAV PATH; AT mode = SPD, aircraft throttles up to maintain min speed
  THRUST_REQUIRED message if AT is disengaged

Above path* (speed window closed):
  Pitch mode = VNAV SPD; AT mode = IDLE to Hold,
  aircraft pitches to VNAV speed + 15 (limited by Mmo/Vmo-11 knots)
  DRAG_REQUIRED message
   
Below path* (speed window closed):
  Pitch mode = VNAV SPD AT mode = SPD, aircraft pitches to -1250fpm
  thrust added to maintain VNAV speed

In VNAV PATH descent opening the MCP speed window results in the pitch mode changing to VNAV SPD. The aircraft leaves the path and pitches to MCP SPD. Programmed not below altitudes will be honored if encountered, however speed constraints will not.
 
VNAV “Approach” sub mode.

This non-annunciated sub mode becomes active when inside 25nm, or past the first WPT of an approach, or if the runway is the active WYPT, or FLAPS down. In this sub mode when the MCP Speed window is opened the FMC remains in VNAV PATH, with A/T maintaining MCP speed. This approach mode allows VNAV to be used with speed intervention on approach. (We model the option in which this mode also engages whenever flaps are selected.)
