LONDON (Reuters) - There are some signs of a decline in airline yields but this is not yet affecting demand for new aircraft, Airbus's planemaking chief Christian Scherer said on Sunday.

Speaking ahead of the Farnborough Airshow, Scherer also said Airbus aimed to beat its recently reduced delivery target of 770 planes for this year.

At the same event, Airbus CEO Guillaume Faury said that demand for widebody jets in particular was very strong.

Airlines including Lufthansa and Norwegian Air have recently warned of a softening in yields - a measure of flight profitability.
