Canardvinge
En canardvinge ((fransk): and) er en mindre vinge på hver side af et flys forende. Begrebet omfatter både bevægelige og fastmonterede små vinger langt foran på flyet. De bevægelige canardvinger kan have samme funktion som højderor på et mere traditionelt bygget fly, og de kan bruges med modsat bevægelsesretning for at give rotation langs længdeaksen.
På de fleste flymodeller vil canardvingerne bidrage til bedre kontrol af pitch / rotation om tværaksen og give større stabilitet, således at det ikke er så kritisk, hvor langt foran eller bagved i flyet vægten af brændstof, passagerer og bagage/gods er placeret. Canardvingerne bidrager endvidere en smule til flyets opdrift.
Enkelte moderne jagerfly er bygget således, at vingerne sidder så langt fremme, at flyet er ustabilt, idet der i tilfælde af, at næsen rettes op, risikeres, at bevægelsen bliver kraftigere, hvorved flyet bliver ukontrollerbart. Under flyvning er disse fly styret af en computer, der registrerer flyets bevægelser og korrigerer i tilfælde af manglende stabilitet. Flere af disse fly er fremstillet med canardvinger for at give mulighed for korrektion af flyets bevægelser.

‘Shark Attack’ by Squadron Leader John Eklund, an RAF Reservist with 7644(VR) Squadron.An RAF Typhoon appears like a shark from the depths. This photograph was taken from the back of a transport aircraft over a lake in the Baltic region where the Typhoons are currently deployed in the NATO Baltic Air Policing Role. Typhoons also secure the skies over the UK and the Falkland Islands to protect the Nation’s airspace. In order to do this they maintain a constant 24/7 QRA (Quick Reaction Alert) force. RAF Typhoons were also deployed in support of Op ELLAMY over Libya.Sqn Ldr John Eklund is an RAF Reservist and in his military role he works for 7644(VR) Media and Communications Squadron based at RAFHigh Wycombe.

Saab JAS-39 Gripen's Canards.
Viewed from the front the #1 XB-70A (62-0001) is shown climbing out during take-off. Most flights were scheduled during the morning hours to take advantage of the cooler ambient air temperatures for improved propulsion efficiencies. The wing tips are extended straight out to provide a maximum lifting wing surface. The XB-70A, capable of flying three times the speed of sound, was the world's largest experimental aircraft in the 1960s. Two XB-70A aircraft were built. Ship #1 was flown by NASA in a high speed flight research program.
