I suspect that my comments about Flytec having announced that the 7000 series will come in 2014 and that I expect an imminent announcement of the 7030 may have stirred up some curiosity about the hardware and especially the display. I will try and get some confirmation about the hardware and comeback to that later but in the meantime here is what I know about displays.
Not necessarily from a functional or practical stand point but from merchandizing stand point I have been bugging Flytec for a color display since the 5030 days. Unfortunately the problem today is the same as it was then, that an affordable and practical sunlight readable color display simply is not available. Yes, there are color displays that are sunlight readable but they are not truly transflective and require an inordinate amount of power (think of how long your smart phone lasts with the brightness all the way up). For a display to be truly sunlight readable in needs a reflectivity ratio of about 15% which is what the original Garmin 76C had. The currently available transflective displays have a reflectivity ratio of about 7-8% and their sunlight readability is poor. For anyone interested in why transflective displays are not readily available there is a good article here: http://www.ecnmag.com/articles/2012/06/ ... e-displays. There are a handful of good transflective displays manufactured like the one used in the Garmin 78, however, these are too small and the producer is not interested in selling in quantities below several hundred thousand units!
Of course, one way to achieve some level of sunlight readability is to just run up the backlighting on a conventional or marginally transflective color display. This approach is fine for a Nuvi or TomTom since they can plug in to vehicle power. Without an external power source the device will either have a short runtime or require a very large internal battery. Short runtimes are at best inconvenient and at worst, render the instrument into a brick when the battery is exhausted inflight. A short runtime can be compensated for with an external battery pack but for hang glider or paraglider this is a cumbersome proposition since it requires a connection cable and means another device to mount, charge and keep track of. Marginal runtimes are also problematic because a rechargeable battery's runtime will deteriorate with age, so a battery that is just adequate when new will become inadequate over time. Large capacity internal batteries are also a poor design choice because of the bulk and weight added to the device as well as longer charge cycles. None of these solutions are elegant, compact, aerodynamic or convenient.
Another possibility that I hear requested is an e-ink display. The contrast and readability of this display is quite good and their availability is better than the transflective displays but they have significant problems for our application. E-ink displays have a relatively slow refresh rate, which is why they are typically used as e-book readers (the display only needs to refresh when you turn the page). In our application, the image is continuously refreshed (2-5 times per second) and at that rate, changing numerical values would be overwriting themselves and a moving compass or map would appear either frozen or blurry. Furthermore, at the cold temperatures we routinely experience, these displays perform significantly slower. The other major problem is that these displays washout with use. Flytec tested e-ink displays and found that at a 5Hz refresh rate, the life of the display would only be about 250 hours of flight time before the quality of the image would appreciably deteriorate.
So considering these limitations and based on my discussions with engineers, I expect a greyscale display on the next instrument. Greyscale has the distinct benefit of being highly readable in direct sunlight, capable of showing greater detail on maps and generally improve readability and aesthetics, while at the same time, meeting low power consumption and low operational temperature requirements. Most importantly, a greyscale display will allow a very powerful device to fit into a very compact housing. I also expect that the hardware is prepared for a transflective color or e-ink display if/when an appropriate one becomes available. However, in the meantime, there is no reason to stall advancement while we wait for a display that may or may not become available. I expect the 7030 display to have a light sensor for adaptive back lighting and be temperature and ambient light compensated to yield the best contrast in the varying temperatures and lighting conditions experienced in our sport. For example, when flying under a well developed cloud, where the sunlight is considerably obscured, adaptive backlighting will automatically bring up the contrast and appreciably improve readability. Adaptive backlighting should have a negligible impact on battery consumption.
At this point in the technology world it is hard to find an advanced device that does not have a touchscreen and I expect that the display on the next instrument will be no exception. Over the years I have discussed the touchscreen concept with many pilots and conveyed the challenges to the engineers. As anyone who has tried to use a smartphone/tablet with gloves on will tell you, it can be quite frustrating. This is due to the fact that most of these devices use capacitive digitizers which rely on the capacitance of the users skin, whereas, resistive digitizers rely on pressure. I know that Flytec has been testing various resistive digitizers to find one ideal for our use. It cannot be too sensitive that a light incidental contact would register and it cannot be too numb that you have to press with so much force that it moves the instrument out of position. The other challenge of touchscreen is ergonomics. Anyone who has used the Garmin Oregon or Montana will tell you that it can be very frustrating to perform certain operations on the touchscreen because a virtual button is too small or too close to the display edge to select while wearing gloves and/or being tossed around in rough air. Users of these devices either cut a finger tip out of the glove or glue a stylus tip to their glove finger tip. The engineers are aware of these challenges and I am confident that activation pressure and ergonomic issues have been appropriately addressed for in-flight use with gloved hands.
Of course, a discussion of display options would not be complete without mentioning the heads-up-display (HUD) concept. Some huge strides have been made in the wearable HUD in the past few years, namely Recon and Google Glass. This is an intriguing technology with potential application for paragliding and hang gliding, however, it is more likely to be a supplemental display rather than the primary display. Since it is impractical (and undesirable) to have all of the information typically shown on a flight instrument presented full-time in your field of view, a HUD cannot negate the need for a display on the instrument. However, Flytec has fully embraced Bluetooth 4LE which should make it relatively easy to send flight data to one of these wearable HUDs.

After my public discussions of the development of the upcoming 7000 series I have been able to confirm preliminary specifications of the hardware in the next instrument and it seems quite impressive.
Dual ARM CPUs. An ARM9 as the main processor for computational and user processes like the GUI (graphical user interface) and a smaller ARM processor responsible managing all of the sensor data, power management and data recording. This dual CPU approach provides operational redundancy and flight recording security.
Grey scale display, fully reflective for optimal readability in direct sunlight with low-power backlight. Light sensor for automatic control of backlighting to improve readability in low light situation. Size is same as 6030 LCD
Anti-glare resistive touch screen (works well with gloves)
3 function keys
High performance 56-channel GLONASS/WAAS GPS with up to 10x per second sample rate
Ultra sensitive and responsive state-of-the-art pressure sensor
Full sensor package like SensBox (gyro, magnetic compass, accelerometer, temperature)
Built-in BT4LE for connectivity to phone/tablet to run flight apps (e.g., FreeFlight, XCSoar, FlySkyHigh, etc.). Also send flights, exchange waypoints, routes and settings between instruments
Built-in FlyLink for connection to remote accessories
Built-in WiFi for connectivity to phone/tablet/e-book readers. Also send flights, exchange waypoints and tasks with scorekeeper/task-setter's computer/hotspot
Audio out/airspeed jack with auto detection of external speaker or airspeed sensor
MP3 audio (voice prompting possible)
Micro USB download and upload (cross platform - no drivers required)
Micro SD card virtually limitless recording
Super easy firmware updating - just copy new firmware to SD card
Cross platform compatibility for upload/download/firmware update (instrument connects as mass storage device)
