Concorde pioneered the following technologies:For high speed and optimisation of flight:Double delta (ogee/ogival) shaped wingsVariable engine air intake system controlled by digital computers[
Supercruise capabilityThrust-by-wire engines, predecessor of today’s FADEC-controlled engines[
Droop-nose section for better landing visibilityFor weight-saving and enhanced performance:Mach 2.04 (~2,179 km/h or 1,354 mph) cruising speed[ for optimum fuel consumption (supersonic drag minimum although turbojet engines are more efficient at higher speedMainly aluminium construction for low weight and conventional manufacture (higher speeds would have ruled out aluminium)[41

Full-regime autopilot and autothrottle[42] allowing "hands off" control of the aircraft from climb out to landingFully electrically controlled analogue fly-by-wire flight controls systems[35]
High-pressure hydraulic system of 28 MPa (4,000 lbf/in²) for lighter hydraulic components[43]
Complex Air Data Computer (ADC) for the automated monitoring and transmission of aerodynamic measurements (total pressure, static pressure, angle of attack, side-slip).[44]
Fully electrically controlled analogue brake-by-wire system[45]
Pitch trim by shifting fuel around the fuselage for centre-of-gravity control[46]
Parts made using "sculpture milling", reducing the part count while saving weight and adding strength.[47]
No auxiliary power unit, as Concorde would only visit large airports where ground air start carts are available.[48]
