I've recently purchased the SSTSim Concorde for FS2004 and I thought I might as well do a little review of it, and explain it a bit more thoroughly than the promo-site (www.sstsim.com) does.

There are a number of Concordes available for FS2004, all very different to each other. The freeware one is great for a freeware plane, but when realism is important, it is found without some important features. Another is said to have great visuals, but not be so accurate. This one however has great visuals, and it has incredible accuracy. For visuals, it is accurate as you'd expect, but also features a nicely done virtual cockpit, and even a fully featured passenger cabin for those who use the Active Camera package. The cabin features the famous Concorde information displays, and is particular to each airline. BA has the very cool dark blue leather trimmed seats for instance. The 2D panel is also finely detailed.

Firstly, this is NOT the plane for those who simply want to fly, without paying any attention to aircraft systems. This is an incredibly complex plane, featuring full hydraulic, electrical and fuel balance systems. To merely start the plane requires going through many procedures.

Pre-flight preparation is important, especially setting the INS correctly, since this plane replicates the real Concorde exactly and features no GPS auto-pilot guidance of any sort. You also need to do some calculations to work out your V speeds, depending on your fuel load. Once you've arrived at the runway, you'll then need to work the fuel system to achieve the appropriate centre of gravity for take-off. This might be around 53.5% or 54%.

Take offs are simply awesome. The engines erupt into a truly thunderous roar, and you'll love the afterburner effects - especially at night where the 4 huge blasts of flame look most spectacular.

But what is most special is the autopilot, or what is properly called automatic flight control system, or AFCS for short. Those used to the standard FS9 autopilot will be staggered by this AFCS. This is a very authentic replication of the item in the real Concorde. It will have you in amazement, especially since this sort of stuff in real life belonged to a plane whose development progressed through 1960's, and was launched in the 1970's. Incredibly sophisticated stuff, and it makes flying the plane quite easy once you are airborne. The system is particularly useful because Concorde by its nature, even in holding patterns maintains higher than normal speeds, and it lands at very high speeds.

You will note that you don't have a Vertical Speed adjustment dial. Instead, climbing to specific altitudes at specific climb rates is achieved by first pitching up to the desired rate of climb, and then pressing the ALT ACQ button on the AFCS. The VERT SPEED button will light-up, and the ALT ACQ button, along with the triangular light underneath it will also light-up. Once the desired altitude has been achieved, ALT ACQ and VERT SPEED will go off, and ALT HOLD button will light-up.

Achieving desired speeds is done by selecting the speed you want in KIAS, from anything between 0 up to a maximum of 400, and then pressing the IAS ACQ button. This function is used only for subsonic flight. So you must be thinking now, well how do we maintain steady supersonic speeds? Well, the AFCS has one of its most special and unique tricks for that purpose. :D

Once you are ready to go supersonic from FL290 and Mach 0.95, you will switch off the IAS HOLD, and even the ALT HOLD! You'll also use the complex fuel system to achieve a centre of gravity of 59%.

Now you will activate full throttle along with the afterburners. You'll then press the MAX CLIMB button.

You will then note the plane start to climb. You'll also note if you watch the gauge indicating rate of climb, that the rate of climb is always changing. And if you watch the Mach Meter carefully, you'll notice that the plane is accelerating close to the overspeed warning, but NEVER overspeeding. :) You will notice that it takes quite some time to go from Mach 0.95 through to Mach 1.3. This is normal. By the time 43,000ft has been achieved, the plane will have reached Mach 1.7 already, and it is time for the afterburners to be disengaged. The plane will still accelerate to above Mach 2.0 just on dry-power! The afterburners are only needed for take-off, and for acceleration between M 0.95 and M 1.30.

By now, you will have seen that the rate-of-climb has changed again, and that the plane is now accelerating very quickly. By 45,000ft, it has achieved around Mach 1.8, which is exactly as it is on the real plane. When it hits around 49,000ft, and Mach 2.0, you will see the MAX CRUISE button automatically light-up. This is indicating that the plane will automatically go into the "cruise-climb" mode. It will attempt to continue climbing as quickly as possible, while always maintaining the maximum cruise speed of around Mach 2.02. If the plane looks like overspeeding, it will climb more quickly. And if that won't prevent the overspeeding, it will temporarily engage MACH HOLD and throttle back the engines.

But in general, it will manage speed entirely by itself, and manage altitude entirely by itself without your intervention. Another thing to notice is that if the plane starts to slow down below the maximum cruise speed, it will put the plane into a slight descent in order to maintain Mach 2.02. So in a typical flight, you'll notice the plane always climbing or descending slightly, depending on atmospheric conditions, and fuel load. As fuel load burns off, the plane will climb ever higher.

Depending on atmospheric conditions, temperature particularly, you may or may not achieve or exceed the optimal 60,000ft cruising altitude. A cold atmosphere will provide the conditions for the superior climb rates and cruise altitude, while a warm atmosphere will have a significant penalty on performance.

Why does Concorde do this, and not maintain one set altitude?

It is for fuel efficiency. It is more efficient to have the engines running at constant power, rather than have them throttle back and forth. And if the plane can climb to higher altitudes while maintaining cruise speed, it will also have better fuel efficiency. Concorde is one of the most fuel efficient jet aircraft in the world when it is in its principal operating regime of 54,000ft-60,000ft flying at Mach 2.0. It can also do this because no other planes regularly fly at those altitudes.

It is also because the special supersonic flight paths are designed to ensure that no two SST's should ever encounter each other going opposite directions since they always fly on specific "tracks". East bound planes use different tracks to West bound planes. If two were to theoretically encounter each other, you could be looking at closing speeds of above 4300km/hr!

In fact, all flights crossing the North Atlantic, including subsonic flights 30,000ft below Concorde utilise various tracks to ensure they fly safely across the Atlantic, and arrive on either side of the Atlantic in an orderly fashion.

When you are ready to begin descent, you'll engage the ALT HOLD function, and simply throttle back to idle, until speed has slowed to Mach 1.6, and the centre of gravity will be adjusted to suit. Only then will descent begin. If (at subsonic speeds only) ATC should request faster than expected descent, a feature called Idle Reverse is used. On the Concorde, this activates the thrust reverse buckets on the two inboard engines.

Now when you need to land, this Concorde has some other tricks up its sleeve. It has a rather sophisticated "Auto-land" system that will land the plane automatically. To intercept the ILS glide slope, you'll use the TRK HOLD feature with the TRK heading set to whatever reasonable heading you'd like to use to intercept the glide-slope path. At this point, the ILS is tuned into NAV 1, and the VOR LOC featured is primed, and ready to activate. Once the plane nears the glide slope, TRK HOLD will disengage, and the plane will turn onto the glide-slope! Then, with the 2nd autopilot engaged for redundancy, the LAND button can be activated, and the plane will execute an automatic landing. The pilot need only adjust the throttles, since the plane will even flare at the appropriate height.

Those landing manually will also appreciate the audible altitude call-outs at various intervals. These are in English or French, depending on where you purchased the plane. My one has someone sounding quite like Mike Bannister making the call-outs.

This surely must be one of the most sophisticated and advanced aircraft to ever be offered for FS2004.

It isn't perfect though. If you have a slower computer, or one with less memory, you'll be running FS in lower detail modes, or experiencing slow-downs. Overall, very much worth its price.

Sounds very good. I just haven't into flight sims so much lately. In fact last about 3 years. Wouldn't mind getting the next MS Flight Sim, and explore the world.

Looking forward to screenshots.

Above: Close up view of the Automatic Flight Control System, the heart of this plane. It allows full "hands off" control of the aircraft and automates many tasks such as trans-sonic acceleration, acceleration to particular selected speeds, climbing to selected altitudes, supersonic cruising and of course automated landings for occasions when visibility is extremely poor.

For automatic landings, both auto-pilots must be engaged for safety and redundancy. The piano-switches will not "latch" unless all supporting systems are functioning correctly

The various buttons are:

MACH HOLD: Holds the mach speed. This activated by the MAX CLIMB/MAX CRUISE modes automatically.

IAS HOLD: Holds the Indicated Air-Speed. This is activated once the IAS-ACQ has acquired the selected air-speed.

IAS ACQ: This acquires the speed set on the SPEED SELECT switch. Once the desired speed has been reached, IAS HOLD is automatically engaged.

INS: The plane is guided by the co-ordinates programmed into the Inertial Navigation System. For this to work properly, the INS must have been aligned and programmed correctly.

BACK BEAM: Allows reverse tracking of ILS.

TRK HDG: This will make the aircraft fly along the requested heading, as programmed into the HDG/TRK selectors. If NAV1 is programmed to a VOR and VOR LOC is primed (indicated by lit triangle under VOR LOC button), the aircraft will fly the requested heading until it nears the NAV1 course, and then VOR LOC will be automatically engaged, and the plane will turn onto the NAV1 course. Can also be used with GLIDE or LAND when an ILS has been tuned into NAV1. In those cases, it would activate GLIDE or LAND when the final approach course is near, and the plane will automatically acquire the glide slope.

VOR LOC: Acquires desired VOR Localiser.

HDG HOLD: Holds current heading.

TURB: This mode is used in conditions of turbulence, and adjusts the way the aircraft is flown by the autopilot so that it is less sensitive and less reactive to turbulence.

PITCH HOLD: Holds the current pitch.

LAND: This performs an automated landing, provided supporting systems are functioning or have been programmed correctly, and provided AP1 and AP2 are engaged for safety/redundancy. The plane will perform the landing based on the data it receives from the ILS, and from the radio altimeter. It will even flare the plane appropriately before touch-down. The pilots are expected to control throttle and thrust reversing.

MACH HOLD: As before.

GLIDE: Acquires and holds ILS glide path. This is used when the pilot will manually land the plane, and he/she merely wants Concorde to acquire the glide slope. The pilot is then expected to take over once the glide path is acquired.

MAX CLIMB: Used for trans-sonic acceleration. This mode will start the plane climbing, and will adjust climb rate to prevent overspeeding while maintaining maximum possible acceleration. As Mach 2.0 is reached, MAX CRUISE will automatically be engaged.

MAX CRUISE: Used in combination with MAX CLIMB. This will put the plane in a supersonic cruise mode. With both modes engaged, plane will climb or descend as needed to maintain Mach 2.02, or engage MACH HOLD temporarily if excessive overspeeding is about to happen.

IAS HOLD: As before.

VERT SPEED: Holds the current vertical speed. This is used with ALT ACQ.

ALT HOLD: Holds the current altitude.

ALT ACQ: Acquires the altitude as set on the ALTITUDE SELECT. Once desired altitude has been reached, ALT ACQ, VERT SPEED disengage, and ALT HOLD automatically engage.

By now, you are probably thinking this is indeed a very sophisticated plane, especially for 1960's/1970's. Another feature debuted on the real plane was a fly-by-wire control system, the first of its type. The engines were also computer controlled (FADEC).

This plane represented the white heat of the British and French technological revolution.

:eek: That control panel... oh my poor head. &(
I never got into flight sims, but absolutely very impressive graphics. -^

Another screenshot, this time of the passenger cabin, at night, with lighting off.

Notice the information displays! :D They cycle between various information. At the moment, it is showing Mach 1.55 at 40,800ft, the outside temperature is a -57°C, and it is also telling us that the speed in MPH is 990.

This is a view from inside Concorde G-BOAD, British Airways. This is in the 80's colours and interior design:

http://www.totalnfs.net/cpd/temp/sstsim_conc_cabin2.jpg

This is on a flight from London's Heathrow to New York's Kennedy International airport. We are at Mach 2.00, 54,500ft, and the temperature outside is -66°C.

It looks very serene and comfortable here, but up front at the flight deck, I was managing an INS failure. =[

Not too dangerous, but just something that needs to be carefully managed, and the plane navigated manually.

I should have taken more noticed when I noted the INS units appearing out of sync right before take-off.

Another screenshot attached, this time on a flight from Heathrow to Washington. The outside air temperature is a chilly -70°C, and for a while, the plane raced along at Mach 2.03, before dropping back slightly to Mach 2.02 at around 57,400-57,500ft.

As fuel load decreased, it gradually started to climb higher and higher. Not quickly climbing, but just gently climbing maybe 5 feet per minute, or maybe even less.

No INS failures this time either. I did DME updating of the INS units before I took off. In fact the only failure was a pilot relating one. Yours truly was too tired to finish the flight, even despite being somewhere quite close to Gander. (almost getting near the East Coast of the USA).

Once the peculiarities and complexities of this plane are mastered, it is quite pleasant and easy to control on long journeys. I do prefer flying the BA Concordes though, since they have rather more informative cabin displays.

The Air France ones have just a blue/white Mach Meter in the cabin, instead of BA's excellent multi-function displays showing speed in MPH and Mach, altitude and distance to go (DTG), along with the initial "Welcome to Concorde" message, and the final "Thankyou for flying Concorde" message shortly before the plane lands.

Did a flight with this plane from Lisbon to London (Heathrow) just before. It had just a light fuel load of about 41,500kg.

I've never tried a short flight with this plane before, with such a light fuel load. For take-off, I found that I really didn't need to use the reheat at all. The climb rate was spectacular! By the time I'd reached 22,000ft, I was already at 400KIAS, so I simply hit MAX CLIMB at engaged the reheat again.

The plane managed to achieve 62,700ft altitude at the highest point in the flight, not long after the screenshot I've attached. :)

And this time, when I was on landing approach to Heathrow 27L, I didn't land the plane manually. I decided to try the auto-land. Following the instructions from the British Airways Concorde manual on the automatic landing phases, the plane was set on the interception course at 210kts, course was set to the runway heading (273), NAV1 and NAV2 were tuned to ILS frequency (109.50mhz) ,LAND button was pressed, and AP2 was engaged.

The triangular light underneath the LAND button illuminated, indicating that the LAND mode was primed, along with GLIDE and VOR LOC.

I got a couple of "glideslope, glideslope" announcements, and then the plane captured the glideslope. Not long after that, it started to intercept the final approach course, and the LAND button illuminated. At 1 dot glide slope deviation, I dialled back the speed to 165kts, and the plane proceeded with its automated landing. :) I got a go-around notice from ATC, but I was determined I would continue to land regardless of the BA Airbus A320 still turning off the runway.

Just before touchdown, I switched off the speed hold, and reduced throttle to idle, while also engaging idle reverse. Concorde touched down nicely on RWY 27L, and I completed the rest of the tasks of slowing the plane down. :)

Next time when I have more than 13.5 tonnes of fuel left over, I might just try the go-around feature. If this plane is completely accurate, then the plane should do an automatic go-around if 2 or more throttles are put in maximum forward position. The plane should begin climbing again, and it should hold the wings level and wait for the next command from the pilot.

That's so over my head all those terms, but very impressive. Btw after taking the Concorde-747 pictures in PSP and highly upping the brightness I could finally see what was on them apart from a few letters, VERY good camera-setting :cool:

That was very neat to watch too! Great way to see just how quick a Concorde is. At cruise altitude and speed, it is going 2.4 times as quick as that 747-400. :)

And you really notice it as this very high glow of light races past so quickly. Before long, it had disappeared into the distance and out of sight.

The lot on the SSTSim site are tempting me into flying this Concorde online, and dealing with actual real ATC rather than FS2004's inflexible ATC. :)
