BOEING 707 circa 1970 - Overhead Panel
The Overhead Panel is accessed by clicking the
button
or by pressing Ctrl + Keypad 5 (with NUM LOCK off).
Engine Starter Switches
These switches are used for starting the engines. Set the switches to GND for starting the engines on the ground. Ground starting requires a source of compressed air, which may be either a ground power unit or an already-started engine, providing air by means of an engine bleed or turbocompressor (see Flight Engineer Panel page). To allow the air to flow to the engines, the covered GND START switch must be set to 'Low Pressure'. High Pressure starts are only possible on a real 707 on engine 3, and are not simulated in this panel.
To re-start engines in-flight, set the switches to FLT - the engine will be spun round by the airflow through it, in order to start. The IGN1 and IGN2 positions are continuous-ignition settings - these are not simulated in this panel.
To communicate with the attendant to connect and disconnect the ground power unit click the "Ground 1 button" in the "Crew Call" section.
Supplementary Panel Night Lighting
This Boeing 707 panel includes a full set of night lighting switches as found in the real plane. An additional switch is available for lighting on the flight engineer panel, located on that panel. Note that the gauge backlighting, the lighting of the overhead and flight engineer's panels and the compass light can work with battery power alone, while the other lights need electrical power from engines or the ground power unit.

Late-model 707s moved the emergency engine shut-off handles from the glare-shield to the overhead panel. These handles may be pulled to shut off the engines. When the handle is pulled, clicking on the lower part activates the extinguisher (this is indicated by a light next to the handle), while the upper part resets the handle. |
Other overhead panel switches
Twin ADF radios - on these later-model 707s, the ADF radios are on the overhead panel.
Pitot Heat - The actual 707 has 2 pitot heat switches - since FS2004/2 only allows for a single pitot heater the two switches move together. The ammeters indicate current flow to the heaters.
Engine Anti-Ice - these switches are simulated, as FS2004 does not actually simulate jet engine icing. The VALVE lights indicate valve transit and come on whenever anti-icing is switched on or off.
Wing Anti-Ice - this controls structural de-icing. This section also includes temperature gauges which indicate the temperature of the hot air applied to the wing. A third switch position is also included which tests the temperature gauges.
Windscreen Wiper - the panel includes a windscreen wiper with 4 speed settings. If the switch is set to OFF, the wiper stops at its current position - to move it fully down out of the way, the switch should be set to PARK.
In addition the panel contains oxygen, emergency lighting and seat belt/no smoking sign switches. These are included for completeness, mostly having no function in the sim.
