 We want to give a bit of an overview on the current autopilot setup before getting into more detail about what changed. One important aspect is that there are only two autopilot implementations in Aerofly FS2 currently. There is the basic autopilot that is found in the Cessna 172 and Baron B58 and there is an advanced autopilot which has more features and controls all the airliners: Airbus A320, Boeing B737, Boeing B747, C90GTx King Air, Learjet LJ45 and Dash8-Q400. These airliner-autopilots can be split into three groups: Airbus, Boeing and Bombardier autopilots. This autopilot update only affected the autopilot found in the airliners, the basic autopilot wasn't touched at all.  We want to give a bit of an overview on the current autopilot setup before getting into more detail about what changed.

-====Boeing====+====Basic A320 Advanced Flight Tutorial==== 
 + 
 +Here is a short step by step for users getting started with advanced autopilot systems in the A320. 
 + 
 +1.**Plan your flight;** this will be loaded automatically into the A320 
 + 
 +2. **set the aircraft onto the runway;** this will set the cruise altitude and prepare everything for takeoff 
 + 
 +3. Advance thrust to **TOGA** or **FLX** and lift off 
 + 
 +4. After a couple of seconds after lift off **engage autopilot** 
 + 
 +5. when **LVR CLB** flashes on the PFD move the thrust levers down to **CLB detent** 
 + 
 +6. as speed increases above -S speed **retract the flaps** 
 + 
 +7 when the PFD shows **DECELERATE** or you see the top of descent on the Map and are close to it, scroll down the selected altitude so the arrival airport elevation + 2000ft or so. Push the **altitude** button in to begin descending 
 + 
 +8. when ILS is received and you're flight plan is about to make the last turn: press the **APPR** button to arm the ILS localizer and glide slope. **Engage second autopilot** 
 + 
 +9. set **flaps 1** and monitor speed. increase flaps when you are below the **amber =** on the speed scale 
 + 
 +10. **gear down** at about 2000ft radar altitude 
 + 
 +11. **flaps full** prior to reaching 1000ft, set autobrake to **MIN**, move the spoiler lever all the way forward to arm them (white marking visible) 
 + 
 +12. after the fully automatic landing **disconnect the autopilot**, touch the brakes to disengage them, taxi to gate, raise flaps, disarm spoilers, etc. 
 +

 +
 +Here is a comparison before and after: note that HOLD and V/S are not correct in the first picture, this has been fixed.
 +
 +{{:wiki:747beforeafter.jpg?500|}}
 +
 +   * added crew alerting system (CAS) with messages like auto-break status, autopilot warnings, takeoff configuration warning for spoilers, flaps, etc.
 +   * added THR REF limit for the auto-throttle system. Uses full thrust for takeoff and reduces to 90% after thrust reduction height
 +   * added buttons on glareshield are now moving
 +   * added vertical deviation to navigation display
 +   * added airport elevation visible on PFD
 +   * added autopilot bank limit selection
 +   * added auto-throttle keeps speed at or above flap retraction speed in VNAV during the approach
 +   * added VREF display
 +   * changed flight mode annunciator on PFD highlights new modes and displays correct names
 +   * changed flap retraction speed visible on PFD speed tape
 +   * changed top right information on ND
 +   * changed trend arc for turn doesn't overlap with center line and is white
 +   * changed total drag of the aircraft is reduced
 +   * changed when set to runway selected speed is V2
 +   * changed flap display is removed when flaps and flap selector are up, same with gear
 +   * changed ND plan mode
 +   * changed MCP buttons illuminated when its dark
 +   * changed: autothrottle "ARM" no longer displayed on PFD, "ALT" armed no longer displayed (and a few others)
 +
 +====Bombardier====
 +
 +**Changes to the autopilot in the C90GTx King Air, Learjet 45**
 +
 +These autopilots are again very different to Airbus or Boeing aircraft. They don't have an auto thrust or auto throttle installed and they have a manual navigation source selection. This means you have to give the autopilot a deviation and course that it fly towards. This can either be the localizer deviation, VOR deflection or FMS lateral offset. Depending on the selected source on your PFD or the PFD of the copilot side the aircraft will either fly the route or an ILS or VOR. And this can be used for either navigation receiver or FMS.
 +Also automatic frequency tuning (auto tuning) is not available here. And it can't autoland and therefor disengages at 50ft AGL.
 +
 +   * Added source selection:
 +      * C90Gtx: press obscured "NAV/BRG" key to the right of the PFD (see screenshot below). This steps through FMS, NAV1, NAV2
 +      * LJ45: press the button "FMS" or "NAV" in the glareshield in front of you repeatedly to select either FMS1/FMS2 or NAV1/NAV2
 +      * XFR or CPL pushbutton selects either left or right PFD (default left). The arrow -> or <- on the PFD indicates which side is used for the autopilot. And on that side the NAV source can be found near the compas rose, top left corner.
 +   * Changed lateral modes:
 +      * corrected basic modes: same as boeing: Bank hold if above 6deg, wing level followed by heading hold if below that
 +      * HDG: can now turn 360°
 +   * added lateral modes:
 +      * NAV key: either arms FMS or VOR (depending on nav source)
 +      * VOR: captures and flies a VOR radial (requires CRS and frequency to be set manually)
 +   * Changed vertical modes:
 +      * no VNAV climb available
 +      * VNAV PATH can be armed prior to top of descent if selected altitude is lower than current alt.
 +      * IAS climb/descent now synchronizes airspeed
 +      * VS now always synchronizes with current vertical speed
 +   * Added vertical modes:
 +      * APPR key: either arms LNAV + VNAV approach or LOC + G/S (depending on nav source)
 +      * basic vertical mode is pitch
 +      * added GA PITCH - just a fixed pitch guidance, cannot be flown by AP
 +      * VNAV can be used for the final approach
 +
 +**C90GTX**
 +
 +A Few changes here and there but mostly implementing the nav-source selection here. This is still work in progress.
 +
 +{{:wiki:sourse.jpg?500|}}
 +
 +   * added navigation source selection: FMS, NAV1, NAV2 including coupling to left or right HSI
 +   * added autopilot target vertical speed to vertical speed indicator
 +   * added autopilot buttons now move in virtual cockpit
 +   * added label “next page” to radio management unit
 +   * changed HSI displays course even if no signal is received, only course deviation indicator is removed
 +   * changed flight mode annunciator on PFD displays correct names for modes
 +   * changed navigation source legend on primary flight display now displays more realistically if no signal received or no if data present
 +   * changed flap display is not displayed all the time and but only if flaps actually change
 +   * fixed ADF frequency on radio management panel and PFD now visible again 
 +
 +**LJ45**
 +
 +{{:wiki:ljsourse.jpg?500|}}
 +
 +   * added crew alerting system (CAS) with info like status of auto-spoilers, warning spoilers extended, take off configuration warning: flaps, trim, etc.
 +   * added take off warning affected items boxed in red on EICAS
 +   * added altitude alert
 +   * added FMS mode (TERM, APPR or enroute) displayed on PFD
