Is the ATR empennage configuration considered a T-tail or a cruciform tail?

Question

How is the ATR 42/72 empennage considered? Is it a T-Tail or a cruciform tail? From the image the elevators are placed quite high on the tail that they can be considered as a T-Tail but is it so?

Looking at the tail of a 727 the elevators are placed at the top of the tail but just leaving the space for the mechanism to move them, whereas on the ATR they are placed in a slightly lower position.

Are there any technical specifications and measurements that clearly define the difference between the two mentioned configurations?

I understand that cruciform means "similar to a cross" but it would be interesting to know, as previously mentioned, if there are specifics about this definition making it clear for everyone from a technical point of view. (briefly, when does a T-Tail become cruciform?)

Answer 1

As far as technical specifications are concerned, some explanation is:

Excerpt from Wikipedia (formatting is mine):

T-tail

DESIGN: The horizontal stabilizer is mounted on top of the fin, creating a "T" shape when viewed from the front.

PURPOSE:

• T-tails keep the stabilizers out of the engine wake, and give better pitch control.
• T-tails have a good glide ratio, and are more efficient on low speed aircraft.
• However, T-tails are more likely to enter a deep stall, and are more difficult to recover from a spin.

T-tails must be stronger, and therefore heavier than conventional tails. T-tails also have a larger radar cross section.

Cruciform tail

DESIGN: The horizontal stabilizers are placed midway up the vertical stabilizer, giving the appearance of a cross when viewed from the front.

PURPOSE: Cruciform tails are often used to keep the horizontal stabilizers out of the engine wake, while avoiding many of the disadvantages of a T-tail.

In reference to your comparison between ATR 42/72 with Boeing 727, if we take out the difference in tail heights (ATR 42: 24' 11"; ATR 72: 25' 1"; B727: 34' 0"), the position of horizontal stabilizer on vertical stabilizer is almost the same on these three airplanes. So they all match closely to a T-Tail configuration rather than a cruciform.
