About the Duke
The Beechcraft Duke B60 is a pressurized, turbocharged, twin engine aircraft with retractable landing gear that first flew in 1966.

The B60 was the final variant of the Duke with the 60 and A60 being made pre-1975. 584 aircraft were built, around 350 or these being B60's with production finishing in 1982. The B60 is regarded as the best developed of this series, but due to the complexities of the design, the cost of running and the servicing requirement relatively few aircraft were purchased.

It accommodates 4 to 6 passengers with typically 1 passenger sitting in the cockpit beside the pilot and 4 passengers in the back of the cabin in a club-seating arrangement. 

The engines on the final version were turbocharged Lycoming TIO-542's producing a maximum of 380hp each.  Either engine was capable of maintaining cabin pressure which was good up to at least 25,000 feet where it could maintain a cabin pressure of 10,000.

About RealAir
RealAir are one of those innovative aircraft developers that everyone loves. Not happy with the shortfalls or the default flight sim engine, they try to add new dimensions for the experiences of the GA flyer.  RealAir have pioneered the development of smooth gauges, accurate stall & spin behaviour, slide slipping and RealView which gives the pilot that  sense of being there by simulating forces experienced in the real world such as stall buffeting.


• High resolution exterior textures with bump mapping
• 3D Ultra-smooth gauge animation
• Accurate simulation of the Duke's pressurised cabin
• Reflections on cockpit glass

Installation and setup
My Duke B60 is the boxed version so no downloading involved and I have a nice colourful dvd box to add to my collection! The box comes with a nicely presented manual which holds most of the things you need to know. After installation you have the RealAir manual, charts and checklists in pdf format available. 

The first thing I did, as I do with all my aircraft, is to print out the check list for easy reference, there's nothing worse when on approach than trying to get the kneeboard up on the display or trying to navigate to the pdf file and write down or remember the check points!

Auto-run takes you to the welcome screen which guides you through the installation and should auto detect your FSX folder, it does allow for an override if you do not have your flight sim on your C drive.

In familiar RealAir fashion there is a configuration utility, the first tab has links back to all the installed manuals for reference and to the RealAir website where you can help help on their support forums.

The options tab allows you to set nose wheel steering, GPS on startup, DME indicator and VS glass reflections. Also here there are settings for  cold & dark or a fully running start up and a strength setting for the stall buffeting.

The panel tab allows you to change the way the mouse interacts with the controls by either click and drag or left/right mouse button. For those of you fortunate to have the Reality XP GNS 430 and 530 units you can set the integration and layout options here.

Finally, there is a tab for download and updates which, if you are connected to the internet will allow you to update your system.

Once you have finished in the Config Utility you will need to set your sim realism to maximum and the p-factor /Torque slider to 75& or more as the flight model relies on this for accuracy.

External Model
There are two versions modelled, one with winglets and one without.  Both have a single vortex generator on the leading edge near to the tip to help reduce the possibility of flow separation over the wing.

The Duke comes with 7 texture variations, 5 North American, one German and one Canadian, I would have like to have seen at least one British livery in the package.  I haven't seen a paint kit available yet for the more creative of us but I am sure one will come along eventually.

Being a true FSX model it takes good advantage of bump and specular mapping. As you can see from the banner shot above it really gives the feeling of depth to the panels and rivets.

It has Nice bright spinners and prop animation in flight with a believable smoke puff on start up.

The animation of the cowls, flaps and doors is very smooth. 

The Doors will not fully open above 30kts, if you should be careless to leave it open on take off, it will be blown shut by the force of the wind, illustrated in the short video clip to the right!

The animation of the nose wheel twisting 90°just before the door closes is very nicely done indeed.

However, I was (at first) disappointed not to see any prop feathering animation, so I took to the manual.  The real Duke doesn't feather the prop when it has stopped, the prop angle actuators only work when the propeller are spinning.

So that was the best response to that query.  I feel sure they have been and will be dogged by that question, R.T.(Choose adequate word).M!!

 I tried this out by feathering first then leaning the  engine and closing the throttle. Sure enough it stopped feathered and could be seen to be so.

VC or not VC?
Well there is no option here as there is no 2D option.  Living in a multi-dimensional world I prefer using the VC, however, a lot of people don't, especially when flying IFR and looking out of the widow is no use, then and you need good clear displays.

RealAir are the masters of smooth flowing 3D gauges, they are astonishingly clear, this should help to placate the 2D enthusiasts.  Most of the gauges and radios modelled would not be found in the original Dukes but reflect the sort of updated equipment you would fly in the real world such as Bendix/King gauges and digital radio equipment.

The VC comes with left click spots to take you to a closer up view of that area and a right click to always take to back to the main view. Try clicking in the coloured regions below to see the view.

The default Garmin 500 GPS system allied to the autopilot is quite good enough and the most familiar for most FS pilots.  There is an option to plug in the RealityXP GNS WAAS 530 and/or the GNSWAAS 430. Not owning this unit I cannot comment on how it interfaces with the Duke.  Be sure to check the instructions though as incorrect set up can result in blank panels.

Operating the switches is easy enough if you are familiar with flying from the VC but also easy to pick up if you are not.

I find it easier to fly in the VC with the yokes hidden so you can see the switches behind.  If you use the excellent TrackIR you can look around them of course.  I figure that I have the yoke bolted to my desk so I don't need to see it on the screen.

Now that's what I call a great 3D view!

Flying the Duke
The emphasis here is on realism so lets give her a spin.

Following the check lists to start her up is easy enough, she's pretty straight forward to fly, almost as easy as a single. RealAir were good enough to model stall buffeting, spins and slide-slipping and gear-up landings so I just had to try them all!

Taxiing with differential brakes is my my choice I think the Duke would be good at a slalom.  Take off with one notch of flap is the way to go. Not much trim is required although I found her hesitant to rotate at her 90kt target, perhaps I wasn't pulling back hard enough or a little more trim could have been added.

Although I had the realism settings to max the torque effect soon dissipates on the roll and didn't require much input from the right rudder to keep her straight.  After rotate the AoA does accentuate the p-factor again but only momentarily.  Flipping the gear lever results in a wonderful clattering and whirring of the gear in a very wide spatial sound quality.  This is thanks to another feature of this product that adds a true stereo quality to most of the sounds that are modelled.

With everything cleaned up the response from input via the yoke and pedals is very sure and smooth.  She didn't require too much trimming to keep her level.  The autopilot was very good and followed a flight plan without deviation.  It accurately maintains the height you dial in too.  It was all very calm with no surprises.

  So I could just sit back and let George fly but what about the stall buffeting?

Sure enough, nose up, throttle back the speed dropping below 70kts the stall buzzer alerts us to the onset of the buffeting. 

The tendency for a spin to follow unless you nose down and throttle up immediately was quite worrying but accurate and resulted in taking recovery actions of neutral ailerons and opposite rudder. 

I got into a few spins trying out the stall and the rate of the loss of altitude is very alarming, stay calm and keep as much height as you can!

Next up was the asymmetric flying, to make the effect worse I shut down the left engine, this should make the torque more noticeable.  Certainly the yaw was very noticeable, after featuring the prop. (See picture above) I was now flying with one foot on the rudder, a bit like the wife resting her foot on the clutch pedal!  Be sure not to increase the AoA as this will make things worse needing more rudder input.

The secondary affect of the right rudder is to make the aircraft bank so some opposite aileron is required as well to keep her straight.  The inclinometer shows the ball to the right and the wings to the left but with only one engine the result is zero slip. Actually it wasn't that bad, returning to the airfield and landing was straight forward enough once you get used to it.

So on to side-slipping proper. On another sortie with both engines I tried this out on approach to bleed off the speed, it seems unnatural to apply opposite rudder to aileron the inclinometer shows the ball to the right and the wings to the left and in a twin not really recommended for more than 30 seconds as it inhibits airflow through the engine on the opposite side.

Finally with much trepidation I tried gear up landing on grass and on water.  You will be pleased to know I made it safely down thanks to my realism setting of ignore crashes. Not my favourite manoeuvre and one I hope I never have to experience in real life but the sparks, dirt and water flying up were impressive.

After trying out all the "extreme" manoeuvres the Duke is happy to go any where you point her (Or should I say him?!)

Short in fancy animations and frills but tall in realism. Test flying the Duke now for more than 5 hours has made me a real fan and presently this is my twin of choice.

A very high quality exterior model although I would liked to have seen more liveries for the flight simmer that does not live in North America.

You have to hand it to RealAir, their dedication to produce accurate sims has more than been demonstrated here.  This simulation will get you wanting to fly twins all the time
I would score this one 8.5 /10 - very impressive.
