BOEING 707/720 panel circa 1959 - Centre Panel

707 Engine Gauges

The Main Engine Instruments

  • The 707 has 20 main engine dials, arranged in columns for each of the four engines. From top to bottom they are Engine Pressure Ratio (EPR), N1 RPM, Exhaust Gas Temperature, N2 RPM and Fuel Flow.
  • For Pratt & Whitney JT3C, JT4A and JT3D engines, EPR is the main indication of thrust.
  • Above the EPR dials, there are thrust reverser indicator lights.
  • Appropriate gauges are included for Pratt & Whitney JT3C, JT4A and JT3D engines (JT3D gauges are shown left).
  • Fuel flow rates are given in pounds or kilograms per hour, depending on your International preferences.

Left Side Instruments

Autopilot Warning Light and Ice Warning Light - the light turns on as a warning when the autopilot is disengaged - the switch turns it off. The Ice Detector light indicates when there is a risk of icing. Since it is not possible to detect moisture from within the FS2004 SDK, this light is faked - it may come on when below FL 230 with the temperature between -15 deg. C and 5 deg. C. The light is more likely to come on in low-pressure conditions (as more moisture exists in such conditions).

Backup Altimeter- the three needles indicate hundreds, thousands and tens of thousands of feet.

The Flight Control Positions Indicator

This instrument, located on the First Officer's panel, indicates the position of the flight controls. When the control column or autopilot are commanding a roll to the left, the aileron position indicator rolls right - this symbolizes the movement of the ailerons up on the left hand side of the aircraft, and down on the right hand side.

Glide Slope Warning Light- this light flashes if you go dangerously below the ILS glide slope during a landing approach

Right Side Instruments

Configuration Warning - this light flashes (and an audible warning sounds) if the aircraft is put into a dangerous or illogical configuration

  1. Throttle above 60%, on ground, with flaps not at take-off setting (20 or 30 degrees)
  2. Throttle above 20% with spoilers extended
  3. Gear down above 270 KIAS
  4. Flaps down above 223 KIAS
  5. Flaps less than 40 in a descent at less than 160 KIAS
  6. Flaps 40 or greater with gear up
  7. Speed below 135 KIAS with gear up

Flap Indicators - these indicate the position of the flaps.

Leading Edge Flap Lights- the leading edge flaps deploy automatically when the trailing edge flaps are set to 20 degrees or greater.

Engine Fire Handles

Stowed fire handle Pulled fire handle Pulled fire handle, extinguisher on The 707 has characteristic emergency engine shut-off handles for each engine on the glare-shield. These handles may be pulled to shut off the engines. When the handle is pulled, clicking on the upper part activates the extinguisher (this is indicated by a light next to the handle), while the lower part resets the handle.
