Please Note: the V1.5 update includes the original ‘SP1’ updates. Because of this the SP1 update is no longer available, or necessary.

All Duke B60 installers downloaded on or after 6 January 2010 have the SP1 (V1.1) AND V1.5 files already included, so if you downloaded your installer after this date, you do not need to install the Duke V1.5 Update.

Version 1.5 of the RealAir Duke is designed to work with either the free Microsoft FSX SP2 update OR the Microsoft FSX Acceleration Expansion Pack installed. We recommend installing the Acceleration Expansion Pack over using the free SP2 update. For more information as to why we recommend this, please read the following thread on the Reality XP Support forum: http://www.simforums.com/forums/forum_posts.asp?TID=32088

The original SP1 updates are as follows:

• Mousewheel support: You can now use the mousewheel to rotate the various knobs in the virtual cockpit.
• Left-click/right-click support: Instead of using the default RealAir click-drag VC knob mouse interaction technique, you can choose to use more traditional left-click/right-click interaction. You can also choose to use click-drag on some knobs and left-click/right-click on others, it’s up to you. For more information read the ‘VC Mouse Interaction’ section of the updated Duke Flying Guide.
• Improved VC camera system: You can now assign keyboard shortcuts to jump quickly between VC camera views. There are also new VC click-spots that allow you to jump between camera views at the click of your mouse button. For more information read the ‘Views’ section of the updated Duke Flying Guide.
• Optional Reality XP GNS WAAS 530/430 panel integration: If you own either of these gauges you can now choose to use the Reality XP GNS WAAS 530 and/or GNS WAAS 430 in place of the default FSX GPS in the virtual cockpit. You can also choose between several radio/GPS layouts using the GNS 530 on its own, the GNS 430 on its own, or both the 530 and the 430 together on the one panel. These GNS gauges are completely integrated into the virtual cockpit including 3D buttons and knobs, and advanced backlighting. For more information read the ‘Reality XP GNS WAAS 530/430 Integration’ Section of the updated Duke Flying Guide. Please Note: Neither the Reality XP GNS WAAS 530 nor the GNS WAAS 430 are included in this package. They must be purchased separately. Please visit www.reality-xp.com for more information.
• Improved support for advanced hardware input devices: You can now use advanced hardware input devices such as those made by GoFlight and Elite to control the HSI heading and course knobs as well as the VOR2 OBS knob. Also, when using these or similar devices to adjust the autopilot altitude you should now correctly see your selected altitude on the autopilot screen.

The V1.5 updates are as follows:

• Optimised LOD (Level Of Detail) models in the exterior MDL file to reduce system resource use when viewing the exterior model.
• Optional medium and low polygon exterior models, in additional to the default high detail multi-LOD model. This option can be set in the updated Duke V1.5 Config Panel.
• Optional mip-mapped textures to further reduce system resource use when viewing the exterior model. This option can be set in the updated Duke V1.5 Config Panel. When using the mip-mapped textures, the FSX ‘Global texture resolution’ slider MUST be set to ‘very high’, or the Duke’s exterior and VC textures will appear very blurry!
• Improved GPS HSI integration. Specifically, the HSI should now work perfectly when being driven by the GPS units (no more Nav flag while under GPS control). This applies to the default FSX GPS and the Reality-XP GNS WAAS units. Please Note: FSX SP2 or Acceleration MUST be installed for this feature to work. Some FSX SP2 users may find that the HSI doesn’t slave properly to the Reality XP GNS gauges - installing the FSX Acceleration add-on should fix this. Alternatively there is an update available on the Reality XP website that should also fix this issue.
• HSI Auto or Manual DTK: ‘Auto DTK’ or ‘Manual DTK’ can be selected in the updated Duke Config Panel. When the HSI is being driven by the GPS, and with ‘Auto DTK’ selected, the HSI course needle will automatically move to the GPS DTK bearing. With ‘Manual DTK’ selected, the HSI course needle must be manually set to the GPS DTK bearing (this is more realistic for an aircraft like the Duke).
• Animated rain-drops on the windscreen glass. Please note: Our personal preference was to make the raindrops quite subtle - we find it more convincing that way. Because of this the raindrops will show up better against some background colours and worse against others. Please also note there are no animated raindrops on the rear cabin windows. When the aircraft is stationary there are raindrops on the windscreen only, and when the aircraft is moving there are raindrops on the windscreen and the pilot’s left and right side windows.
• Improved ‘Cold and Dark’ function. The code for this function was rewritten to make it more reliable, so if you choose ‘Cold and Dark’ in the Duke Config Panel, you will now see a ‘cold and dark’ cockpit every time the Duke is loaded.
• Improved engine starting. Starter motors now more reliable and the Duke should start at sea level on first press of the starter buttons.
• More realistic generator gauges. The generator needles now behave more realistically, indicating an increased current load when the various lights, heaters, avionics, gear and flaps are in operation.
