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...)

Headset Communication - Flight Sound X Adapter - Review

Occasionally you come across a device which really makes your simulation life simpler.  I wanted to use the David Clark headset (model H10-13-S) I have owned for sometime in the simulator; however, the two plugs on the headset are the large style plugs suitable for insertion into an appropriate audio module in the real aircraft – not a computer sound card.

Real Headsets Verses PC Headset

Apart from the obvious difference, a real aviation headset is constructed to a very high standard, is robust, and provides a high fidelity sound rarely replicated by an inexpensive PC style headset.  Unlike a PC headset, real aviation headsets are designed to produce excellent sound whilst providing maximum buffering of ambient sounds (aircraft engines, wind, etc). In the simulation world, ambient sound can be dogs barking, cars driving down the street or daughter's yelping... 

Flight Sound X

The Flight Sound X adapter allows you to use a variety of real aviation headsets with your simulator, to filter out engine and ambient noise and hear and communicate with air traffic control (VATSIM, etc).  It’s as easy as plugging in the two plugs from your headset into the device and flying – it is that easy!

The device does not require a separate power source, is small, and connects directly to the USB of your computer via a USB cable.  WIN7 64 bit recognises the device on start-up and additional software and drivers are not required.  A small LED light on the device indicates the unit is operational (red light).

Initial device set-up requires you open the sound module in Windows, navigate to the appropriate menu and change a few settings within your sound card to allow sound and microphone ability to be transferred to your headset.  Instructions (with pictures) are supplied with the device, so you cannot make a mistake – even if you do not read English.

A benefit to using this device is that it’s small and can fit more or less anywhere within your flight deck.  Another pleasant surprise is the device’s construction; it is made from aluminium (painted black) rather than plastic.  As such, it looks quite attractive and is far more robust than plastic counterparts.  Another benefit is the actual placement of the plugs which is at the side of the device rather than at the top of the device.  This ensures that your headset cable and plug are not in a position where you may accidentally stand on them!

Technical Details:

  • USB 1.1 and 2.0 compatible
  • Plug and Play with Windows 7/Vista/XP and Mac OS X
  • Uses standard General Aviation headset connectors (PJ-068 and PJ-055B)
  • Supports headset impedances of 100 to 600 Ohms
  • Supports Mono and Stereo Headsets
  • Compatible with standard microphone types (electric, dynamic and powered dynamic)
  • Powers microphone bias (+9V) from USB port (no external power needed)
  • Zero delay voice feedback (side tone) feature
  • Output frequency response (20Hz-20KHz)
  • Weight: 100g
  • Size: 65 mm(L), 55 mm(W), 25 mm(D)
  • Compact, robust, anodised aluminium enclosure  

Made in New Zealand

The device is made in New Zealand.  The Kiwis usually make innovative and functional products – good work New Zealand…

If you navigate to PC Aviator (Australia), they have a good blurb on the product which has Frequently Asked Questions section.

The Flight Sound X website is www.flightsounds.com

This device would have to be the simplest item I have purchased, set-up and used with flight simulator.  And it WORKS too!

My rating is 10/10


In a future post we will discuss how to separate sound, so you can hear engine sounds from one pair of speakers and ATC, call outs and navigational aids through the head set.

Live ATC - Listen to ATC In Real Time

Many virtual aviators are confused when it comes to understanding the language used by air traffic control and pilots.  The three questions  that are often queried are:

What to say ?

When to say it ?

How to say it ?

There are several on-line tutorials available to learn air traffic control and aviation language, however, often a far easier and more interesting method is to actually hear ATC talking to pilots and vice versa.  This in conjunction with a little reading can get you up and flying quickly without making mistakes  when flying on-line.

To listen to live ATC, go to Live ATC, select your airport code and frequency and sit back a listen.  The frequencies are already on the website, so all you need is the ICAO or IATA code of your airport.  Here is a link to find your airport code.

Live ATC can be be listened to either via the web or if your "on the move" and really cannot be without ATC, then your android or i-phone. ATC is a volunteer organization, so expect some adverts on their website.

I've also made a link in the navigation bar (right hand side column).  Click the link to be directed to the ATC page.
