Why are canards used?
Canards are part of an airplane that functions as a stabilizer or elevator and installed in front of the main wing. A canard is used for several reasons such as increasing lifting force, the stability of the aircraft’s controls and flow changes over the main wing.
Why do aircraft have canards?
A canard is a fuselage mounted, horizontal surface that is located forward of the main wing to provide longitudinal stability and control. Depending upon the installation, it may be a fixed, moveable or variable geometry surface and may or may not incorporate control surfaces.

Does SU 30MKI has AESA radar?
The Su-30MKI is also equipped with a N011M passive electronically scanned array radar, OLS-30 laser-optical locator system and Litening target designation pod to guide air-to-surface missile and laser guided munitions. The N011M will be replaced with new Zhuk AESA (active, electronically scanned array) radar.
Why do people say canards are not efficient?
Canard detractors (aka aerodynamicists) claim that canards are not efficient at all. They point out that most canard aircraft can’t use flaps to lower their stall speed, and the main wing never reaches its maximum lift coefficient because it is not allowed to stall.
Why are canard wings more efficient than conventional tails?
Canard Efficiency MythsCanard owners like to claim their aircraft are more efficient than conventional designs. Their technical argument is that the forward wing (canard) creates lift rather than a downforce like conventional tails.
How does a canard affect the pitch of an aircraft?
However, the canard can actually make your aircraft pitch up further. The increase in angle of attack causes both the canard and the wing to generate more lift. If the canard’s increase in lift is greater than the wing’s, the nose will pitch further up.
Which is more fuel efficient a canard or a conventional plane?
The canards cruise 10 to 15 knots faster and are more fuel efficient than conventional designs only because they give up performance in other areas. An optimized conventional aircraft designed to equivalent standards could achieve the same or better results.
