May I know if there are any turn and bank indicators on the pilots instrument panel and where is it located at?

As has been pointed out in other posts, the top right instrument, appears to be a VSI (white needle) with an overlaid bank indicator (gold dial) over a ball slip/skid indicator.

$\begingroup$ That's not a VSI, the scale is wrong and it doesn't have a negative indication for descent. I have a Cuban friend who trained in Russia, I will ask him what it is. $\endgroup$ Aug 7, 2022 at 0:53

1$\begingroup$ It goes 10-20-30 clockwise, and 10-20-30 counter-clockwise, as a VSI would. You posted the picture! ;) See also i.stack.imgur.com/liZTS.png $\endgroup$– Max RAug 7, 2022 at 1:50

$\begingroup$ Turns out you nailed it. Combo VSI with an appropriate range for the behemoth's performance, with turn and bank. My friend Guajirovich confirmed it. 🤣 $\endgroup$ Aug 7, 2022 at 1:54

1$\begingroup$ And sadly, these questions and comments are all worded present tense. The An-225 had a turn and bank. :( $\endgroup$– Max RAug 7, 2022 at 2:58

1$\begingroup$ @UshbyTechnicalTeam presumably the device has both a canted bank gyro AND a connection to to the static ports inside the same enclosure. Your intuition is correct, there’d be no way to accomplish both objectives with just one mechanism. $\endgroup$– Max RAug 11, 2022 at 4:12

$\begingroup$ Are you sure that that's not only a slip and skid indicator ? the VSI is a pitot static reading, how come it's combined with a gyroscope ? I am not sure about your answer, sir. Do you have manual reference ? $\endgroup$– user64784Aug 10, 2022 at 15:36

$\begingroup$ From my point of view it makes sense to have a combined instrument. When you are trying to make a coordinated turn often you want to maintain your altitude, or maintain a stable sink or climb rate. It makes sense to me to have that information centralized in one instrument. The part immediately above the center of the instrument is the bank indicator. As far as I know, the POH for the AN-225 is not publicly available. At least I have not been able to find it. $\endgroup$ Aug 11, 2022 at 16:31
