For FSX Developed by iFly, published by Flight1

The newest members into the 737 family (600/700/800/900) continue to make the 737 series the most popular and reliable commercial jet transport aircraft in the world. Such is the popularity of the 737 series the order book has passed the 6,000 mark.

The 737 is a short-to-medium range aircraft and is a big favourite with airlines due to it's reliability, simplicity and reduced operating and maintenance costs. The newest NG variants move the 737 into the 21st century and continue to make it a fantastic airliner. Advanced technology such as winglets allow airlines to save fuel, extend the aircraft's range, carry more payload and reduce engine maintenance costs.

We are already given a 737-800 as a default aircraft in FSX, but words cannot describe how much better the iFly version is. FSX has long needed a high quality 737 simulation, and within a short space of time we got 2.


Included in the Download
The add-on is available from the Flight 1 website as a download or boxed version (I am reviewing the download version) and costs, depending on exchange rates, about £40. But before you go running for the hills after seeing the price tag you should know that you get 7 (seven) variations of the 737. Those being the 600, 700, 800, 900, BBJ, BBJ2 & BBJ3 variants. You can customise each variation via the configuration manager (more later) including engine types and wing-tips.

What you do not get with the download is a wide choice of liveries – you only get the iFly house livery. That's not a massive problem as there are now lots of free liveries available to download from the internet (See below). These are easy to install via the configuration manager. In some ways I like this approach as your hard drive doesn't get clogged up with liveries you don't want, but on the other side of the coin I would like 4 or 5 liveries included.

You are also given 6 manuals that tell you everything you need to know about the 737NG, including a tutorial which is more than adequate for a crash course in the aircraft (pun not intended!). Don't expect to read the manuals in a few minutes though, more like a few days. They are very comprehensive.

External/Internal Model

The flight deck of a 737 will be familiar to most tube-liner fans and the iFly team have done a fantastic job and have produced a brilliant 2D and virtual cockpit. Some developers have tended to shy away from creating 2D cockpits but iFly have made this one a great place to fly from. Then you get to the VC which is quite simply stunning. The viewpoint is spot on and combined with Track IR I almost felt as though I was in the aircraft for real (even without Track IR it's still superb). Not all buttons and switches are fully functional, but the ones that you need to get up and running all work perfectly and have the click-sounds as you would expect.

Hud Full Auto LAnd
 
Captain IFR

In the BBJ variants you are given a HUD (Heads-Up-Display) which I have not encountered on any other airliner add-ons. I can see the advantage of this and sooner or later all commercial airliners will have this technology, but for some reason it didn't appeal to me. Whilst it worked and gave all the required information I struggled to take my eyes off the PFD when landing in minimums. I think that the HUD is a great inclusion and other people may get more from it that I did.


Overhead Panel
 
Radio Stack

Most people will want to show off their add-ons by way of screen-shots meaning that developers have to get their external models perfect, and I'm glad to say that the iFly 737NG is one of the very best. It doesn't look bad from any angle and I couldn't find any rough edges. I'd go so far as to say that it's perfect. Add in one of your favourite liveries and you'll spend more time outside the aircraft that inside it (British Airways 737-900 is particularly nice). Whilst you are taking screen-shots you will need to let the auto-pilot take over...


Auto-Pilot & FMS
The heart of any commercial airliner is the auto-pilot and flight management system (FMS), and to people like myself who love delving into the depths of the aircraft it is essential that you learn how to operate this correctly. If you own other Boeing add-ons the FMS wont be anything new to you, but you can always learn more, so much more in fact that the manual devotes over 100 pages to the FMS (the operations manual is 529 pages long). If you are new to complex procedural airliners it will take a long time to fully understand how everything works, but once it clicks you'll never want to fly a default aircraft again.

Programming the FMS is fairly simple and importing a flight plan from FSBuild is very easy. Even when asked to perform holds, fly direct to another way-point the FMS is very easy to navigate around and make the changes. Just make sure that you enter the correct way-points or you may have problems!
Configuration Manager
If you want to get the most from the iFly737NG you will need to use this.

Prior to each flight, even before loading up FSX, you are required to set your payload and fuel load for the variant you will be flying via the configuration manager.

Setting the payload is easy; you can do it manually or select 'random'.

There isn't a fuel planner included which is a shame so you will need to either use a conservative estimate or find a fuel planner on the internet.

Once you are done and the information has been passed to FSX you will need to make a note of the zero fuel weight (ZFW) and centre of gravity (CoG) as these are both needed in order to program the FMS correctly.
 
Once the aircraft is loaded into FSX you will need to open up the panel state program via the FSX menu bar to set the panel state and establish ground power. It took me a few times to remember to do this, but it's a lot easier than creating a default cold and dark flight only to find out it wont work with your add-on.

The configuration manager is also where you add new liveries to the variants. This was a little tricky at first but I soon got the hang of it – just double check the model you are adding the livery to is the correct one.

Flight Handling
Whilst this is an add-on that will predominantly be flown with the auto-pilot I encourage you to hand fly it during departure and arrival; the hand-flight characteristics are sublime. Quite often I wouldn't engage the auto-pilot until I was above 20,000 feet because it's so much fun to hand fly. Even on approach and landing I hardly ever made a poor landing because the 737 is so easy to get down to the runway; almost every touchdown will be silky smooth.

Sound Package
If you've ever flown in a 737 cast your mind back to the sounds of the engines because that is exactly how they are in this add-on. The take-off roar is amazing and the constant drone of the engines during cruise is spot on. Something odd that I noticed was that upon touchdown the engines sounded like they were on fully throttle for a split second until the reverse thrust kicked in, even though the throttles were at idle.

Addon Liveries
As mentioned earlier, the download base pack only gives you the models and variations with the iFly livery, but there are 15 recommended repaints available for download via the product page, if that is not enough, then the Flight1 file libraries will give you more along with other updates and files. See below for a sample of those liveries.


Boxed DVD Version
Many users of this type of simulation prefer to have the DVD version, this just takes the enjoyment that little further with printed manuals, a very good tutorial, poster sized panel overview and of course, a nice box to proudly display in your bookcase! Flight1 inform me the boxed version also comes with 35 airline liveries as well.

At only 5 USD more it is well worth considering too. More here



Verdict

I began this review a little apprehensive as I wasn't sure that anyone could match up to the fantastic PMDG737 that I was still flying in FS9.

After 1 flight all that was forgotten and I fell in love with this fantastic add-on. I had considered buying the PMDG NGX package, but after looking at the base pack price which is almost 25% more than the cost of this whole package I won't even entertain it.

This add-on that iFly have produced is an absolute classic and by far the best airliner add-on I have used for FSX.

Without any hesitation I can award the iFly Jets: The 737NG the 'Mutley's Hangar Award for Excellence' and a 10/10 rating.
