REFLECTOR: DIY EFIS

[Mark Magee]

I believe any hot/cold and screen brightness issues could be addressed cost effectively with after market products for the iPad market.
The tech at Levil said the iPad overheating shutdown issues have been occurring on glare shield mounts, and that a customer of Levils is installing THREE iPads (2 full size and a mini) as a PFD currently under the theory that they will live comfortably in their operating temp range mounted in the panel mount.

>> 2.       Tablets in the panel are dedicated to that purpose. I don't want my flight instruments to double as my email client, traveling web browser, and portable game system.
>> 3.       Software that is specifically designed to be a primary EFIS. This is the biggest hurdle. Most products that I've seen are flight-planning apps or in-flight charts that have added an EFIS screen. I can foresee these same products deleting this "add-on feature" for liability reasons when they discover pilots have started using them for critical flight information. Also, until the programmers of these systems are committed to providing a product that is reliable enough for IMC, I don't have the confidence that every revision of their software will be tested to an acceptable level of assurance.
>> 4.       High level of integration. I'm willing to pay a lot more than the cost of an iPad for a device that will integrate with my approach GPS, radios, autopilot, Vertical Power system, and engine monitor.
>>  
>> Until #3 and #4 are solved, I plan on having a dedicated EFIS and using a tablet for backup navigation and future EFIS experimentation. There's one EFIS manufacturer (GRT?) that allows a tablet to serve as a second screen for their product. This seems like the best of both worlds . . . dedicated equipment with off-the-shelf expansion options.
