From the JP-X Series, the JP-4:

With AGM-1 you open/close the Cockpit.

With AGM-2 you activate the Machine Guns.

With AGM-3 you activate the Brake Parachute.

With AGM-4 you Jettison the Weapons (Only the misiles).

With AGM-5 you activate the Refuel Probe.

With AGM-6 you turn on/off the Ligths.

With AGM-7 you activate the Arresting Hook.

AGM 8 - Nothing.

When you are in cockpit, you see 3 screns:
-The one in the left indicates the Weaponary (In you want to change the name above just erase "CPT. Ed Winters" and write your nickname), the weapons are custom names so if you want other weapons, change the names to your custom weapons names.

-The middle screen indicates the Throttle, Fuel, Brakes, Landing Gear and the percent of the Flaps (I recomend the flaps between 9% and 3% in the flight - do the VTOL down).

-The screen in the rigth indicates the Altitude (Feets), Speed (Miles per Hour), G Force and "Match" (The plane in sound speed) . Also other 2 things.

Notes:
1.- If you are in a computer, pass the mouse over the buttons to know what do they do.
2.- Literally, the half of the buttons in front (the box with a lot of buttons) doesn't do nothing XD.
3.- This plane was created in a computer.

Enjoy =D (This is my first plane in the "Inside Work" Update, the JP-3 is only an update of a old plane that I never post until now :D )
