DLR tests fuel-saving, quieter approach procedures in EU project
Germany's DLR research centre has trialled new approach procedures aimed at cutting fuel burn and noise, with almost 1,000 simulated approaches flown by more than 70 pilots. The trials suggest energy-optimised descents and digitally transmitted routing are workable even in dense traffic, the centre said.
Germany's DLR aerospace research centre has tested procedures aimed at making approaches more fuel-efficient and quieter. The trials took place under an EU-funded project called DYN-MARS, and involved more than 70 pilots flying almost 1,000 simulated approaches across a range of traffic conditions.
One of the systems trialled was an extended flight management system. It automatically recalculates the vertical flight profile when air traffic control issues short-notice speed instructions, so that aircraft can descend under idle thrust for as long as possible. Expected route changes were also sent to the cockpit digitally via CPDLC.
According to DLR, the trials show that energy-optimised descents and digitally transmitted routing can be handled operationally even when traffic density is high. The work is to be taken further in a follow-up project, DYN-MAX.
