Centre Panel
Fuel Load The fuel load for left (wing), centre & right (wing) fuel tanks in kilograms. The engines only ever draw fuel from the wing tanks (left & right). The centre tank only pumps fuel into the wings. Under normal running, the wing tank levels will not drop until the centre tank is empty.
| Hydraulic System There are two separate systems (left & right), each has two pumps. One pump runs from the engines & the other is an AC electric Auxillary pump. A DC electrical pump operates a completely separate hydraulic backup system. The top dial shows the level of fluid in the resvoir of each system. The next dial down shows the pressure in each system. The three dials along the bottom show brake pressures for the combinations of foot & hand brakes. The top row of four switches operate the hydraulic systems. Without engines running only the inner 'Aux' switches will provide hydraulic power. If the engine powered system is running, the Aux system can be turned off. Although it is not covered in any detail by FS, on this model the flaps, tail trim, spoilers & gear do not operate properly without hydraulic power.
Standby Attitude A basic standby attitude indicator.
Altitude Alert The amber light gives a warning when your altitude is approaching the set value. It also warns if your altitude slips more than 200 feet from the set altitude.
Engine Vibration & Overheat Shows the amount of engine vibration. A reading of '2' is normal. Engine overheat lights red whenever the engine EGT gauge goes into the red.
Reverser Unlocked Lights when reverse thrust is active. One either side of the engine gauges.
Thrust Index The real aircraft had tables of thrust index settings, according to temperature & pressure. The pilot set the relevant index number (the yellow numbers in the centre) so that during take off the gauge reads a true power level for the conditions. The gauge does work in FS and will automatically calculate the index number using the current temperature & pressure. The lower the index number is, the more power is needed to produce the 'normal' thrust level. The pointer should always read at least 100% during take off and if it can not reach this level take off should be aborted. You can manually alter the index number by clicking on the bottom half of the gauge. Clicking the top half of the gauge resets the index number according to the current temperature & pressure.
N2 Percent RPM Engine revs. The scale allows for 110% because original maximums were often extended after the aircraft's launch.
EGT Exhaust Gas Temperature Temperature in Celsius. The temperature should normally be in the green section, occasionally in the yellow and never in the red. Engine overheat also gives a warning light at the top of the centre section of the panel.
Fuel Flow Fuel flow for each engine in kilograms per hour.
Oil Temperature Oil temperature in Celsius.
Flap Position Shows the position of the trailing edge flaps. The gauge can be used to move the flaps by clicking with the mouse. Click on the left side to raise a notch, click on the right side to lower a notch. 8 degrees - Takeoff 18 degrees - Short Takeoff 26 degrees - Approach 45 degrees - Landing Many One-Elevens used a different range of flap settings for takeoff - 6, 13, 20 degrees giving Long, Normal, Short takeoff run. Some also had an option of 3 degrees. All marks had the same 26 & 45 for approach & landing.
Tail Trim This shows the position of the variable incidence tailplane. This is the 1-11's elevator trim (or pitch trim) setting. The scale runs from -2 degrees (nose down) to +10 degrees (nose up). The thicker white line shows the allowable trim range for takeoff. The model needs 3 degrees nose up for takeoff, otherwise it may not rotate at the correct speed. For simplicity, 3 degrees was the standard takeoff setting for the 1-11, regardless of loading (though some used 4). The gauge can be used to move the tailplane by clicking with the mouse. Click on the left side for more nose up trim, click on the right side for more nose down trim.
| Landing Gear Lever & Indicators Click the lever to raise or lower the landing gear. If the landing gear is raised & locked up, no lights are lit. If the gear is in transition the 'GEAR UNSAFE' light is lit. If all the gear is down & locked the 'GEAR UNSAFE' light goes out & the three green lights at the bottom are lit.
OAT (Outside Air Temperature) Ambient temperature outside in degrees centigrade.
Fuel Temperature Fuel temperature entering engines in degrees centigrade.
Cabin Alt to Baro Pressure Used to regulate cabin altitude (cabin pressure). The 'A' knob on the left selects the required cabin altitude selectable from -2000 to +9000 ft. The 'R' knob on the right selects the rate at which cabin altitude is altered (between 150 & 1000 ft/min) The knob in the middle adjusts the reference poiner at the top. Set it to 'current pressure' in inches of Mercury.
Cabin Altitude VC only. Shows the current cabin altitude from 0 to 40,000 ft. Also shows the current pressure differential on the hull in psi 0 to 10 (max 7.5). The required cabin pressure is set using the 'Cabin Alt to Baro Pressure' gauge above.
Cabin Altitude VSI VC only. Shows the current rate of change in cabin altitude from 0 to 2,000 ft/min. The required cabin pressure & rate of change is set using the 'Cabin Alt to Baro Pressure' gauge above.
Water Injection This simulates the system fitted on some Spey 512 engines. Not all One-Elevens had water injection. Water injection versions of the Spey engine can be identified by a 'W' in the name, e.g. Spey 512-14DW Used on takeoff, the system injects water into the rear of the engine to reduce the temperatue. This allows more power to be used for a longer period without overheating. To operate, simply click the switch on the pedestal (VC only). Alternatively, on the 2D panel you can click either amber light to turn the water injection system on. The amber lights show when the system is switched on & the blue show when the water is being injected. Once switched on, water injection occurs automatically when the engine RPM goes over 92%. 12 gallons of water is available which is enough for two takeoffs. Water level is displayed on the dial above the switch (VC only). In FS the water tank is automatically refilled whenever the aircraft is stationary.
