The Gemini does provide bank angle.

In the short term it provides pitch attitude that slowly transitions to vertical speed. Any change in pitch gets displayed immediately.

TT has promissed a user selectable option for a true attitude display if you prefer it over the current method. But that does not exist yet so don't count on that till it is available.

The display method being used on the Gemini has been used in the TT ADI and ADI pilot AP for years now.

Anyone that actually flys behind one will tell you that it would be very usable in IMC for backup.

The subject of the technical differences between the two has been discussed many, many times in the past - but - the reality is either one will functionally work just fine in a real world scenario and like Brian said, take the sales rhetoric out of it and the real world flying capabilities of both are just fine. That being said, I see the D1 as more of a backup for the flight bag...sort of like backup radio, backup GPS, etc.. and not necessarily a perfect candidate for a panel installation as a backup for an IFR panel. Firstly because the price point is such that you'd be just as well off getting a D6 for a TT PFD, secondly you have actual altitude and airspeed.

Don't get me wrong, I quite like the little D1 and think everyone should have one. I've flown it quite a bit now and it's a remarkable piece of equipment - especially for the certified folks. But for homebuilders we have access to the D6 or the TT at around the same price point so I feel that is a better expenditure of your money as an installed product.

All of the aformentioned products are excellent choices so to suggest otherwise would be dubious - you'd be happy with any of them, and any of them should keep the shiny side up in normal flight regimes.

Just my 2 cents as usual!

Cheers,
Stein

Default TT Gemini

As an aside to this conversation, if you decide on the TT, I've got a brand new in the box Gemini PFD for sale I wound up with. $1,100.00 vs. $1,300 from TT.

Thanks..
