* '''A/P''' - Engage/disengage autopilot | * '''A/P''' - Engage/disengage autopilot | ||
* '''F/D''' - Flight director | * '''F/D''' - Flight director | ||
==== How to use ==== | |||
* '''Default mode of when autopilot engage''' | |||
HDG HOLD mode: Maintain heading when engage. | |||
ATT mode: If bank angle exceeds 5deg when engage, keep that bank angle. (there's bug, will be fixed) | |||
VS mode: using vs value when engage. | |||
If FD mode was engaged, mode is inherited. | |||
* '''Mode''' | |||
Lateral control | |||
HDG HOLD: keep set heading. | |||
HDG SEL: follow the heading set on counter. Change value when HDG HOLD or press SEL button when other mode such as VNAV, LOC mode. Once reach to setting heading change to HDG HOLD. | |||
LNAV: follow the activated route. | |||
LOC: when arming, keep previous mode and then capture ILS or VOR course, follow that course. | |||
Eg: VOR course capture. | |||
Location->Position Aircraft On Ground. Enter RJAA to Airport and select Ranway 16R then press OK. | |||
Equipment->Radio settings <F12>, Set 114.50 of KZE VOR frequency to Nav1 and set radial 260. | |||
Take off and once ship is steady then AP on and set heading 220. | |||
Press LOC button. | |||
Select EFIS control knob to VOR and VOR L on. | |||
Once you get to near cause of VOR AP changes to VOR mode then ship follows VOR radial as long as signal healthy. | |||
Vartical control | |||
VS : keep targeted vertical speed to reach selected altitude. | |||
FLCH : keep fixed climb thrust or flight idle and control the pitch to maintain speed thus vertical speed varies. | |||
VNAV : Follow the FMS target altitude and thrust. | |||
ALT HOLD : When you press HOLD button, keep altitude when button pressed. Counter value does not change. Once VS of FLCH reaches targeted altitude, it holds that altitude. | |||
* '''Autopilot using LNAV/VNAV e.g. From KATL to KMIA.''' | |||
#Location->Position Aircraft On Ground. Enter KATL to Airport and select Parking A1111111 then press OK. | |||
#Press BATTERY button on OHP then rotate APU knob to START. This switch automatically spring back to ON. Press APU GEN button if its not on. | |||
#Adjust backlight of Overhead panel and Instrument using OVHD and PNL/FLOOD outer knob. | |||
#Autopilot->Route Manager. Enter KMIA to Arrival: and select Rwy: 27. | |||
#Click 001 KMIA-27 (27) in route window and note distance 518.0nm then press Route button. | |||
#Equipment->Map. Check and modify route not to have sharp angle way point. Click 002 ATL then press Remove button. Remove 011 DHP and 012 LUVLY as well. Add any way point using Fixes in Map to intercept the KMIA-27 localizer. eg. Add HILAY, HOXIL, HENDN after THNDR. | |||
#Equipment->Fuel and Payload. Set Total fuel wight to noted mileage 518 * 45 + 10000 = 33500lbs then press Balance button. Check Gross Weight not exceed Maximum Take Off wight then Press Close. | |||
#Set cruise altitude in Route Manager to 41000 feet. Be careful that if you have heavy weight you can not reach high altitude and of cause if you don't have enough distance you can not reach that cruise altitude ether and that will cause VNAV not available. | |||
#Now you can save this route for later use. | |||
#Press Activate button then Close Route Manager. | |||
#You may close Map or keep it open with Transparent to check course. | |||
#Set cruise Alt to MCP Altitude counter to 41000. Left click on AUTO to 1000 then press and hold the left button or scroll center button on left lower of knob to adjust. | |||
#Set IAS counter to V2+15knot. This time 185knot. Press and hold center button of mouse on IAS knob you can decrease the value. | |||
#Press LNAV, VNAV buttons. | |||
#Set A/T ARM switch to arm. | |||
#Adjust QNE. Set Autobrake to RTO. | |||
#Rotate SEAT BELTS knob to ON 4 times to notice cabin crew to close door and set door mode to auto. | |||
#Set Left START IGNITION knob to start. | |||
#Once engine start to rotate, set left FUEL CONTROL switch on pedestal to RUN. | |||
#When engine starts and is stable, continue to Right engine as well. | |||
#Stop APU. | |||
#Make sure no warning light is lit on overhead panel. | |||
#Release parking brake (Shift + b). | |||
#Then taxi to runway 08R While taxing lower the flap to 5 according to take off weight. This time the weight is light so 5 is enough. | |||
#Turn on Landing Light, Logo light and Wing light. Turn off the cabin light (Ctrl-l). | |||
#Once you are on runway 08R, then press Heading HOLD button to set heading to runway heading. | |||
#Turn off the Taxi light. | |||
#Advance thrust lever to half way then press Ctrl-t to engage A/T to TO/GA mode. | |||
#Rotate when you reach VR. (Around 140knot, middle of orange bar of speed tape. I will add V1, VR and V2 indicators in future) | |||
#Keep pitch angle 15deg then gear up when V/S ind plus. | |||
#Wait until gear up, then adjust pitch trim to maintain F/D pitch bar center. | |||
#Flap up according to the speed. | |||
#Once ship stable without any force apply to control, then press AP. | |||
#Turn on the cabin light. | |||
#Now ship follows LNAV course and climb to cruise altitude by VNAV. | |||
#Around 10000ft, turn off the landing light. | |||
#When you pass the FL14(Japan) FL18(USA) press STD button to set STD to QNH. | |||
#Once reach to the cruise altitude and before you reach the TOD(Top Of Descent) (approximately 100NM before Airport depends on cruise altitude), set Altitude counter to 2500 (Arrival airport AGL 2500, this time KMIA elevation is 8ft thus 2500ft). If you get “Reset Altitude” warning message you may not use VNAV any more so please use normal Autopilot such as V/S or FLCH mode till approach. | |||
#When ship reaches TOD, automatically start to descent with 0.78M or 280Knot. | |||
#When pass the transition altitude (FL14) press STD button and adjust QNH. | |||
#Around 10000ft, turn on the landing light. Turn off the cabin light. | |||
#Equipment->Radio settings <F12>, Set 109.50 of KMIA 27 ILS frequency to Nav1. | |||
#Press IAS knob to speed intervention. Set 210 when you reach 3200AGL. | |||
#Flap to 1. | |||
#Press APP button at place 3nm to HENDN. | |||
#Once you capture localizer then set speed 190. | |||
#When GS capture set Flap to 5. Set speed to 130. | |||
#When you reach 2500ft set Flap to 15. | |||
#Gear down during 2000ft to 1500ft AGL. | |||
#Set AUTOBRAKE to desired position. Usually position 1 is enough. | |||
#Set SPEEDBRAKE to arm. | |||
#Set Flap to 20 then 25 according to the speed. | |||
#Reducing speed around orange bar + 5knot and Flap full down. | |||
#Be stable before 1000ft AGL. | |||
#Once touch down, set thrust revers on until 60knots this time A/T is disengaged.. | |||
#AP disengaged automatically at 50knots then exit nearest taxi way then go to your parking spot with flap up. Turn off landing light. Turn on taxi light. Start APU. | |||
#Stop at parking, set parking brake then shut down the engine. | |||
#After embankment, stop APU then BATTERY off. | |||
