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...)

No advertising on this website - EVER!

New Interface Module Installed - SMART

The installation of an OEM flaps gauge to the simulator was the catalyst to the design and development of an additional interface module. 

The module, called 'SMART' is a platform to accommodate the various components necessary to configure and drive the flaps gauge.

LEFT:  OEM Flaps gauge installed to Main Instrument Panel (MIP).  A new interface module was designed to incorporate the 400 hertz needed to power the gauge.  Furthermore, SMART is also responsible for the interface a several other OEM gauges.

SMART has also been used to accommodate the interface cards necessary to use the OEM AFDS units, Autobrake Selector knob and the Used Fuel Toggle.

The SMART module has been discussed in a separate section as a subset to the Interface Module section.


Also of note, is that the throttle page, a subset of the Flight Control pages (main menu) has been updated.

The page now refers to the most recent throttle quadrant used in the simulator.  There is also a internal links section, at the bottom of the page.
