T-Tail

Example

T-Tail

A T-tail is an empennage configuration in which

the horizontal surfaces (tailplane and elevators)

are mounted to the top of the vertical stabilizer.

looks like the capital letter T when viewed from

the front or back, hence the name.

horizontal control surfaces are mounted to the

fuselage at the base of the vertical stabilizer.

T-tail is especially popular

on gliders.

Advantage

The tailplane surfaces are kept well out of the

airflow behind the wing, giving smoother

flow, more predictable design

characteristics, and better pitch control.

It can operating at low speed, where clean

airflow is required for control.

T-tail configuration also allows high

performance aerodynamics and excellent

glide ratio as the empennage is not affected

by wing slipstream.

The T-tail arrangement is also commonly

found on airliners with rear-mounted engines,

including trijets. The Douglas DC-9,

Disadvantage

• The T-tail aircraft may be

Susceptible to a deep stall.

• In a deep stall, the airflow

over the horizontal tail is blanketed by the disturbed

airflow from the wings and fuselage.

• In these circumstances, elevator or stabilator

control could be diminished, making it difficult to

recover from the stall.

Due to a lack of airflow over the elevator from

a forward mounted engine (piston or

turboprop), low speed control is reduced and

low speed operation is more difficult for

aircraft not designed for low speed operation.
