There is a light near the elevator trim control on the left side that lights up white when the elevator trim is at the 0% (neutral) setting.
The two gauges with "α" (alpha) on them at the top right of the panel indicate "air-fuel alpha" for the left and right engines. Air-fuel alpha is a percentage that relates to the fuel to air ratio (i.e., mixture). 100% is the perfect mixture (14.7:1) but going slightly richer "reduces combustion temps. which reduces your chances of preignition or detonation". Readings below 100% are richer (more fuel) and readings above 100% are leaner (less fuel). A reading of 0.9 (90%) gives you peak rpms.
There are three fuel gauges on the Pe-2 Series 35. Two of the gauges are visible on the lower right panel, but the third one is tucked out of sight below the other two. You may need to occupy the rear gunner's seat momentarily to see the third gauge.
[Unconfirmed] There are two outer tanks and one inner tank in each wing and there is one fuselage tank (see this picture). Here are the fuel gauges for each tank:
The top left gauge is for the four outer wing tanks.
The top right gauge is for the two inner wing tanks.
The bottom gauge is for the fuselage tank.
