HC-16 Marliner is the short-to-mid range, rear-mounted, twinjet airliner at the same class of DC-9.

HC-16-200 was the longer sized version from the HC-16-100, capable up to 60 extra pax so in total 140 passengers and usually used for mid-range and mid-to-high-density short-range flights.

Controls (note the controls is same as HC-16-100) :

AG.1 = Left engine/engine #1
AG.2 = Right engine/engine #2
(Note : you can perform engine failure simulation even perform gliding with this config)

AG.6 = Turn on navigation lights (beacon and signal light)
AG.7 = Turn on interior lights
(Note : the exterior view of interior light looks strange in the day flight lol, but in when in the night flight with AG.7 turned on along with AG.6, it looks gorgeous)

VTOL = Flaps
Trim = Adjust flaps and tail stabilator
