Like continuous descent operations, continuous climbs allow an aircraft to take-off and reach its cruising altitude in one smooth manoeuvre. The flight can attain the most fuel-efficient flying conditions quickly and also reduce the fuel used by levelling-off at different altitudes.

Whilst the benefits are often not as great as with continuous descents, there can be emissions and noise reductions. The ability for air traffic management to work with airlines and airports to implement such measures depends on the capacity conditions and complexity of the airspace, but continuous climbs have been implemented at a number of airports including:

The Sustainable Aviation partnership has promoted continuous climb techniques at UK airports, with the procedure being used up until 10,000 feet. From 55% of departures using the technique in 2006, implementation has grown to 67% in 2014. Sustainable Aviation is also promoting best practice in take-off and landing cycle operations through the publication, in partnership with others, of codes of practice.

As part of the REACT-Plus project of the SESAR programme, at Budapest Airport in Hungary, aeronautical engineering company PildoLabs worked with stakeholders to implement continuous climbs on nearly all departures from the airport as of March 2013.

Part of another SESAR project, the Atlantic Interoperability Initiative, looked at the benefits of continuous climbs from the two main Paris airports and was jointly investigated by Air France and the French air traffic management provider DSNA The demonstrations showed around 100 kilograms of CO2 savings per departure at Charles de Gaulle Airport and about 300 kilograms at Orly Airport.
