KerbalX

This airliner is a major update of the Kerbus K-380, with newly designed wings, new intakes and more passengers, and even better fuel efficiency.

Cruising speed: 620m/s
Cruising altitude: 11750m northbound/southbound, 11950m eastbound, 11550m westbound
Fuel burn during cruising: 0.182 unit/s

Notes for taking off:
Set throttle to 1/3. Set control point to the inline cockpit. Stage the engines. When the plane is rolling at 35m/s, turn to full throttle. Pull up at 80m/s. We recommend climbing at 10 degrees. Turn on the afterburners (AG1, only the outboard ones) at 3000m. Ease off the climb at 10000m and fly level at the required altitude and speed. Turn back to dry mode and engage prograde lock for cruising. In prograde cruising mode, the plane would first climb and descend in 200m cycles, gradually converging to the optimal cruising altitude. To make convergence faster, temporary turn to SAS when the vertical speed is above 5m/s, level the flight and turn back to prograde mode.

Notes for landing:
Approach at 80-90m/s and land at 65-80m/s.

Notes for land ditching with the parachute:
Stage the parachute at the back. When the back parachute partially opens, lower the landing and lock the brake, then stage the forward parachute. Deploy the tail fin (AG3) and flaps (AG2). The parachutes are set so that the plane tumbles at the last 500m and land front gear first at minimal speed.

Notes for water ditching with the parachute:
Stage both parachutes. Set the full deployment altitude of the back parachute to 1000m or higher, and that of the front parachute to 800m. The plane should crash into water at a more vertical angle. This should protect the fuselage from breaking apart.
