Left Side Instruments
Flight Director Switch and Ice Warning Light - the switch turns on the Flight Director cross-hairs on the ADI. 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).
True Airspeed Indicator- this indicates knots TAS, and is useful for navigation purposes.
Backup Attitude Indicator - unlike the ADI, this can run from battery power alone, and is used when AC electrical power is unavailable (for example, failure of all engines).
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
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 14 degrees or greater.

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. |
Altitude Alerter
The altitude alerter is used as a reminder of assigned flight level. On approaching the selected altitude, a tone sounds and a light comes on on the altimeters when 700 feet away. The light also comes on (and the tone sounds) if deviating more than 300 feet from the selected altitude. The Altitude Alerter is not an automatic altitude capture function - one must manually level off when reaching an assigned altitude! | .![]() |
