An additional display in the cockpit shows optimised recommendations for the entire approach process. These recommendations enable the pilots to organise the approach profile in such a way that it can be carried out largely at a fuel-saving idle speed with low noise levels.
The expert group on procedures deals with the definition, design and evaluation of innovative flight procedures. In this connection, the vertical profile is paramount. The Procedures group explores possibilities of noise reduction at take-off, depart, approach and landing in compliance with safety and economic efficiency. This development is realised in the stages of aircraft performance calculation, fast-time simulation, the use of flight simulators and flight tests. Finally the findings are tested in operational flights. The Procedures group is highly involved in DLR’s aircraft noise alleviation activities, in cooperation with external partners including Deutsche Lufthansa and Frankfurt Airport.
