am using same system as Tarq
I was one of biggest naysayers especially with regard to VFR, head down time, lighting, and writing without looking etc
have been using them in Auckland for a while now - reasonably okay traffic levels and a good mix from light singles through med turboprop and jets ( our biggest users ) to a good level of heavies.
I'm sold.
lighting is not a problem ( and we get more sun than WN
) learning to use the lighting adjustment controls correctly solved that one.
I calibrate as soon as I sit in position and very rarely have to redo it before handing over again.
With experience I find that the head down time is actually reduced as a single touch is quicker for most information ( and I can read it again afterward).
Yes we have had ,and are still having, some minor issues but a lot of these will be dealt with in the upcoming upgrade.
have to say that for me personally, I've gone from NAY to YAY.
