CASA C-101 Aviojet

The CASA C-101 Aviojet is the primary jet trainer of Spain and clearly has the same basic features as contemporary aircraft, especially the tandem cockpit in which the instructor in the back seat sits higher than the student pilot in the front. Straight low mounted wings can also be found on similar aircraft. What is different on the Aviojet are the long, narrow air intakes in front of the wing roots and the single exhaust below the tail instead of at the very end of the aircraft. The horizontal stabiliser is at the junction of the rear fuselage and vertical stabiliser.

The long, narrow oval air intakes are one of the main features of the CASA Aviojet. Additionally, the nose is more pointed than similar aircraft.

The other key recognition point of the CASA C-101 is that the exhaust is way before the end of the aircraft, below the horizontal stabilisers.

Different versions

The different versions of the CASA Aviojet can externally only be distinguished by the presence of hard points under the wings, for storage of weapons.

C-101BB & C-101CC

The BB and CC versions of the Aviojet have a provision for storage of weapons under the wings. Additionally, they seem to have ventral fins under the exhaust, but we don't know if this is standard. For the rest they looks the same as the decicated trainer versions. The difference between both versions is that the C-101CC is a dedicated light attack version, while the C-101BB has a dual training/attack rol. In Chili these aircraft are designated T-36 And A-36 Halcón respectively.

This Aviojet of the Honduras air force clearly has hard points under the wings, making it a C-101BB or C-101CC. We know that it is also used for training so it must be a BB model. (photo USAF/WikiMedia)

On the side view of the C-101CC you can better see the ventral fins near the exhaust, which seem typical for the C-101BB and C-101CC. (photo Mike Freer/WikiMedia)

C-101EB

This is the dedicated trainer version, used exclusively by Spain. It has no weapons or provisions for them, nor ventral fins.

A part of Spain's Aviojets - all C-101EBs - is used by its demonstration team, Patrulla Águila.

Confusion possible with

Aermacchi MB339

mb339pan

The canopy and straight wings are similar to that of the Aviojet, but there are many difference in other parts. The landing gear of the MB339 is shorter and the air intakes are much smaller and nearly round. Furthermore the MB339 has the exhaust at the very rear of the aircraft.

AIDC AT-3

This is a twin engine jet trainer with engines at the sides of the fuselage but for the rest it looks quite similar to the Aviojet. 

British Aerospace Hawk

The Hawk has smaller air intakes, more D shaped, swept wings, a curved leading edge of the tail and horizontal stabilisers with anhedral. This should be enough not to mix it up with the CASA.

Aero L-39 Albatross

The Aero Albatros also has wider air intakes than the Aviojet. They have nearlky the shape of half circles, and are placed at the side of the fuselage, just after the cockpit. The exhaust it at the rear of the fuselage.
