To takeoff:
- Push parking breaks at Launch.
- Close hatches (both of them).
- Stage - ignite the proppellers
- wait about 10 seconds
- Stage - ignite the jets.
- wait about 5 seconds
- Full Throttle
- When the airplane starts to move, release breaks
- At 10 m/s, activate Flaps (0)
- Rotate at 50 m/s
- Keep a positive vertical speed of 5 m/s steady. Full throttle. Gears up.
- At 300 meters high, retract flaps (0). Keep full throttle.
- Climb at 5 m/s vspeed until cruising altitude
- At cruising altitude, turn off jets (9) to save fuel
- Aim to keep the airspeed at cruising speed
- Keep full throttle while the plane is too heavy to keep the cruising speed.
- Down throttle as fuel is consumed and the plane gets lighter to keep an airspeed at the cruising speed.
Cruising
For maximum autonomy, the ideal altitude is the one in which you keep the airspeed at 100m/s and pitch at 0°.
As the plane is getting lighter you will notice she will drop the nose below the horizon to keep the altitude steady. Climb until the pitch is 0° to correct it.
If you are using mechjeb, just set the airspeed to 100, the pitch to 0° and let mechjeb do the rest.
To land:
Avoid landing with fuel on the external tanks. If an unplanned landing is to be executed, eject the external fuel tanks still with fuel on the sea or above not inhabited land.
- Ignite the jets
- Approach at *60m/s with full flaps
- Gears down at 300M high
- Touchdown with -7m/s vspeed max
- Turn jets off
- Reverse propellers (R), full throttle
- Breaks
- Cut down the throttle at 10 m/s ground speed. Unreverse propellers.
- Parking breaks at full stop.
Emergency Procedures
NEVER engage breaks while flying. NEVER !!
Propeller engine failure
- At takeoff
- Above 50% of the maximum takeoff load, eject external fuel tanks immediatelly.
- Declare pan-pan.
- Climb to 1.000M.
- Deactivate the counter part engine to prevent unbalanced thrust. Keep jets burning.
- Land in the nearest appropriate airstrip
- At cruising
- Ignite the jets
- Deactivate the counter part engine to prevent unbalanced thrust
- Recalculate the autonomy and proceed to the destination if the safety limits are satisfiable.
- Divert to an adequate airstrip otherwise.
- At landing
- Deactivate the counter part engine to prevent unbalanced thrust
- Declare pan-pan
- Proceed with the landing
Jet engine failure
-
At takeoff
- Above 25% of the maximum takeoff load, eject external fuel tanks immediatelly.
- Declare pan-pan.
- Climb to 1.000M.
- Deactivate the counter part engine to prevent unbalanced thrust. Keep jets burning.
- Land in the nearest appropriate airstrip
-
At landing
- Eject external tanks.
- Turn off jets.
- Declare pan-pan.
- Proceed with the landing.
Multiple engine failure
- At takeoff
- Eject external fuel tanks immediatelly.
- Declare mayday.
- Climb to 1.000M.
- Rebalance the remaining engines to keep the thrust vector acceptable
- Land in the nearest appropriate airstrip
- At cruising
- Ignite jets immediatelly
- Declare pan-pan.
- Recalculate the fuel consumption to the nearest airstrip, add 20%.
- Eject the external fuel tanks with the surplus fuel.
- Eject them manually, one by one, from the outermost to the innermost
- Proceed to the nearest airstrip.
- At landing
- Eject external fuel tanks immediatelly.
- Declare mayday.
- Rebalance the remaining engines to keep the thrust vector acceptable
- Proceed with the landing with caution - you may not be able to go-around.
Ditching
If you face the harsh decision to ditch the plane on a body of water:
- Powered ditching
- Declare mayday.
- Ignite all engines
- Rebalance the remaining engines to keep the thrust vector acceptable if any of them are faulty
- Keep the airspeed at 60 m/s on the descending
- At 100 M high, deploy flaps
- Proceed to the splash down at 35 m/s airspeed, no less than -5 m/s vspeed.
- Do not deploy gears
- Keep the fuel tanks - they will help absorbing the impact and providing buoyancy.
- Unpowered ditching
- Declare mayday.
- Close all intakes to save drag.
- Eject all external fuel tanks.
- Keep the airspeed at 60 m/s on the descending
- At 15M high, deploy flaps
- Pray.
- Proceed to the splash down at 35 m/s airspeed, no less than -5 m/s vspeed.
Crash landing
- Powered crash landing
- Declare mayday.
- Ignite all engines
- Eject all external fuel tanks.
- Rebalance the remaining engines to keep the thrust vector acceptable if any of them are faulty
- Keep the airspeed at 60 m/s on the descending
- At 100 M above the ground, deploy flaps
- Deploy gears
- Proceed to the touch down at 45 m/s airspeed, no less than -3 m/s vspeed.
- Unpowered crash landing
- Declare mayday.
- Close all intakes to save drag.
- Eject all external fuel tanks.
- Keep the airspeed at 60 m/s on the descending
- At 15M above the ground, deploy flaps
- Deploy gears
- Pray.
- Proceed to the touch down at 45 m/s airspeed, no less than -3 m/s vspeed.
