Question

Which tail profile is shown in below diagram?

(a) Cruciform tail

(b) T – tail

(c) H – tail

(d) Conventional tail

The question was posed to me in an international level competition.

I'd like to ask this question from Tail Geometry and Arrangement topic in section Airfoil and Geometry Selection of Aircraft Design

Answer 1

The correct answer is (a) Cruciform tail

To explain I would say: Cruciform tail viewed from front will look like a ‘plus’ as shown in figure. T – tail will look like letter T and similarly H tail has shape of letter H.
