The A120 is Azure's next-generation wide-body airliner with four powerful engines that fly higher and farther away.The A380 is one of my favorite aircraft, so I designed this aircraft with the A380 as a prototype.

Start The Aircraft:

(The start checklist is on both sides of the cockpit)
1.Turn on the Parking Brake.
2.Turn on the BAT.
3.Turn on the Fuel Pump.
4.Start the APU.
5.Turn on the APU Bleed.
6.APU power 70%, open the engine electric door.
7.Press the START.
8.Confirm engine start, turn off APU BLEED, turn off APU.
9.Turn off the Parking Brake.
10.Turn on the ADIRS
11. Turn on the HYD

Control

Flaps:Pull the VTOL down to lower the flaps
Height Mode:Click ALT or AGL to switch height mode
Slimming:Click “Release Fuel” to release fuel
Fill with fuel:Click “Reful
Couplings” to fill with fuel
Landing: Lower the flaps and landing gear, and the speed of the aircraft should be controlled between 200-280km/h (124-173mph, 107-151KTS).
Cruising: Keep the speed at around 700km/h(434mph,377KTS).

Auto Throttle:

1.Press "AT" to activate the autothrottle
2.Use the "AutoThrottle" lever to set the target speed.
3.Be careful! Automatic throttle must not be used when landing.

Navigation

Note that the order in which the coordinates are entered is reversed. For example, if you enter "1145,1919", you need to enter "1919" and then press "N" to switch coordinates, then enter "E" to clear the current coordinates, and then enter "1145", and finally you successfully enter "1145,1919". Navigation tells you the direction and distance of coordinate points.(This feature is provided by @kaqiusha123, thanks to him here)
Thanks to everyone who helped during the production process.

Enjoy your flight time!
