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).

Genuine B-737 Throttle Quadrant - Purchased!

I was very surprised to have found a real 737 throttle quadrant at more or less the same time I was debating which throttle to use in my simulator.  Negotiations have been successful and I've been told my new TQ has just arrived in Florida (from Arizona) where the TQ will be refurbished.

The TQ belonged to a scraped South West Boeing 737-300 series aircraft. 

Attached to the TQ is a two-tier avionics bay.  I was going to replicate a 737NG bay from MDF wood, so the addition of the bay is a added bonus. 

The bay still has workable DZUS rails so adding avionics is just a matter of drop and screw!  Although the NG has a three-tier bay, I was never intending to add all the instrumentation that a NG would have.  I cannot see the benefit in duplicating avionic modules which will never be used.  

Therefore, the two-tier bay will work very well for me.  As I've mentioned in the static section of this blog (tabs) everything with a simulator is about compromise, and the level and detail and realism that you want.  For me, a real avionics bay (even if not a NG bay) is a bigger plus than a wooden bay full of fake instrumentation.

The TQ will be completely dismantled, cleaned and serviced.  Parts that are not required for simulation will be removed.  The lower section of the TQ and bay will be cut off  as this section of the quadrant is not necessary.

The unit will then be retrofitted with appropriate SYS hardware which is to be mounted in the avionics bay out of sight, but easily serviced by removing a few avionics modules.   USB cabling will be routed along the inside bottom of the TQ to come out at the front of the throttles.  This will allow easier connection to a computer.  FD to Phodgets will be used to configure the Throttle to flight simulator.

The unit will be a non motorized unit, however, with the use a a DC motor (run from electrical power) the trim wheels will spin and manual trim will be able to be changed.

Finally, a new coat of paint will be applied along with repaired or replaced labels.  A trim stab will also be attached to the unit.

One of best things in my opinion with using a genuine throttle is the realsism involved.  But another positive aspect is the fact that the chance of breaking a real throttle quadrant is next to impossibel!

I've seen a few TQ's now and it shocks me the condtion they are in - I wonder what pilots do in the flight deck.  Often the throttles are scratched, stained and even chipped by continuous use.

The images here are the throttle straight from the aircraft.  Over time I'll be attaching devlopment photographs as the throttle is converted.
