Mission Statement 

The purpose of FLAPS-2-APPROACH is two-fold:  To document the construction of a Boeing 737 flight simulator, and to act as a platform to share aviation-related articles pertaining to the Boeing 737; thereby, providing a source of inspiration and reference to like-minded individuals.

I am not a professional journalist.  Writing for a cross section of readers from differing cultures and languages with varying degrees of technical ability, can at times be challenging. I hope there are not too many spelling and grammatical mistakes.


Note:   I have NO affiliation with ANY manufacturer or reseller.  All reviews and content are 'frank and fearless' - I tell it as I see it.  Do not complain if you do not like what you read.

I use the words 'modules & panels' and 'CDU & FMC' interchangeably.  The definition of the acronym 'OEM' is Original Equipment Manufacturer (aka real aicraft part).


All funds are used to offset the cost of server and website hosting (Thank You...)

B737-800 NG EVAC Panel - A Nice-looking Panel 

A quick post to showcase an OEM (Original Equipment Manufacturer) panel just installed to the center pedestal.  The evacuation (EVAC) panel is usually mounted in the AFT overhead; however, as I am still developing the overhead panels I have temporarily installed it into the center pedestal.  

The EVAC panel’s use needs no introduction – it is triggered by the flight crew if and when evacuation of the aircraft is required / occurring.  A switch in the passenger cabin can be triggered by the cabin crew alerting the flight crew that an evacuation is imminent.  The panel is only used when on the ground (obviously).

The EVAC panel is from a B737-800 NG and incorporates an arming/off switch, flashing red coloured EVAC annunciation, alarm cancelling pull knob and a piecing alarm (horn). 

The panel is not connected to any function within Flight Simulator; therefore, an interface card is not required.  A continuity test, using a multimeter, is used to ascertain which pins in the Canon plug correspond to which switch/toggle/alarm.  The backlighting is 5 Volts whilst the alarm and annunciator is 28 Volts.

Although the panel serves no true function in the simulator, it is a good-looking panel that improves the aesthetics of the center pedestal.  Once the overhead is fully developed the EVAC panel will be removed from the pedestal and placed in the aft overhead panel (the correct location).

The EVAC panel is an airline option and is not stock standard to the aircraft.

Below is a video showing the panel’s use.

Isn't the EVAC panel located in the forward overhead, just behind the electric metering module?

Best regards,

Hello Youssef

The EVAC panel is located in the AFT Overhead. I have currently installed it temporarily into the center pedestal as I am still working on the overhead. When the overhead is completed the panel will be relocated to the correct area. Cheers, F2A

Hi, I was wondering where you obtained the EVAC panel from? I've been searching for one for a long time!

Best wishes,

Hi Nick

The panel was an e-bay purchase.

I've had a few of these panels and they turn up from time to time. If I see one I'll let you know. Best, WilloW
