-The '''Droop Nose''' was a distinctive feature of both [[Concorde]] and the [[Tu-144]]. When these aircraft were in service, the pilot would lower the nose to improve visibility of the [[runway]] and [[taxiway]]s. When in flight, the nose would be raised. Concorde also had a moving [[visor]] that would slide into and out of the nose. The Tu-144's visor was part of the nose and did not retract.
-The [[Fairey FD2]] experimental aircraft had used a droop nose; when one was converted into the BAC 221 as a testbed for the Concorde wing shape, the droop nose was carried over.
-The [[Concorde]] droop nose was designed and manufactured under sub contract by [[Marshall Aerospace]] in [[Cambridge]], UK.
-The nose can be drooped to one of two positions - 5 degrees (for taxiing and for take-off), and the fully drooped 12.5 degree position (used during landing, when the nose-high attitude of Concorde requires this lower nose position so the pilots can see the approaching runway). The nose and visor are hydraulically operated, by a small lever on the co-pilot's side of the cockpit. There is also a standby droop system if the main system fails (operated from the cockpit centre console), and as a last resort if both hydraulic systems fail, a lever can be pulled in the cockpit which releases the mechanical latches, allowing the nose to fall under gravity to the 5 degree position.
