Takeoff

The tail trim setting is important for takeoff.  For simplicity the 1-11 always used 3 degrees of nose up trim on takeoff, regardless of flap setting or weight. If you do not set the nose up trim, it will not rotate at the correct Vr speed. The Tail Trim gauge can be used to accurately set the nose up trim.  Click it to alter the trim setting. Click the top half of one of the Thrust Index gauges to automatically set the correct index number before a take off.  Correct take off power is with Thrust Index reading 100% or above (too much thrust may result in engine overheat warnings unless Engine Top Temp is switched on) If the runway is short or the atmospheric conditions may require it (hot / high altitude), switch on the water injection system to allow for more engine power to be used. Flaps should always be set at 18 degrees, unless excess runway length permits 8 degrees. Click the 'Speed Reference Chinagraph' on the left of the main panel to get the correct rotate speed (Vr) for the aircraft's current weight & flap setting. The 'checklist' toggle button gives the essential settings needed for a takeoff.  Each setting is shown with a tick or a cross, making it easy to quickly check if your configuration is correct. Normal speed for the climb is 300 kts, with the power setting not exceeding 94% RPM or continuous EGT not exceeding 540 degrees (green area). If the climb rate needs to be higher, reduce speed.

Cruise

Normal cruise altitudes range from 18,000 ft to 32,000 ft.  Operational ceiling is 34,000 ft Normal cruise speed is Mach 0.70 - 0.73.  Mach 0.77 is the maximum cruise speed. With climb configuration set, the aircraft has a natural maximum altitude depending on its speed & weight.  It is usual to rise to higher cruise altitudes when fuel is burnt off.   If the tail trim is registering more than 0.8 deg nose up, you are probably pushing the model too high.  If the tail trim is going nose down, you are probably cruising too low.

Landing

Click the 'Speed Reference Chinagraph' on the left of the main panel to get the correct landing speed (Vat) for the aircraft's current weight. It is normal to use a constant engine RPM between 83% to 86% during approach & landing (depending on weight). Approach at Vat+40, 16 degrees flap. Speed at Vat+40, select 26 degree flap when the GS indicator is between 2nd & 1st dot. Speed at Vat+20, select 45 degree flap when the GS indicator is passed 1st dot. The flaps will cause some nose down attitude.  Compensate with nose up trim.  It is normal for the model to need around 4-5 degrees of nose up trim with full flaps selected. When flying at the correct speed on the glideslope, the One-eleven should be level, showing zero degrees of pitch on the Attitude Indicator. Be aware of the maximum landing weights & their speeds.  While the aircraft can land safely at full weight, over weight landings were only done in an emergency. Normal landing weights will give Vat speeds of between 115 & 135 kts. This 1-11 does not have auto spoilers.  Extend spoilers when main wheels are down.  Lift dumpers will also extend when aircraft is on the ground (except 200 series). For best results with landing the 1-11, it was normal to leave the power on until just before touchdown, rather than using a prolonged hold off with large flare.  It is normal to touchdown fairly flat, almost on all three wheels.

Range, Payload & Fuel

With a maximum payload, the amount of fuel must be limited to keep below the maximum takeoff weight (MTOW) The model is set up for maximum range, with a full fuel load & a light payload.  If you would like to carry more payload, you will need to reduce the fuel to make MTOW. Maximum payload is 26,000 lb for the 500,  23,000 lb for the 510 & 20,500 lb for the 475. The models are all set up to be under MTOW, with maximum fuel load by default.
