Test flights for Airbus A320neo with LEAP-1A engines begin

[fungus]

"CFM International’s LEAP-1A engines powering the Airbus A320neo have taken flight for the first time.

The first A320neo flight equipped with a pair of LEAP-1A engines, operated by F-WNEW, took off from Toulouse Airport on May 19, Airbus said in a statement.

During the four hour and 25 minute flight, experimental test pilots Philippe Perrin and Malcolm Ridley took F-WNEW to a maximum altitude of 39,000ft, conducted tests on engine speed variation and did system checks. Also on board were flight engineers Jean-Michel Pin, Tuan Do and Philippe Pupin."

Next-generation plane engines take a LEAP towards delivery

If there's one key selling point that aerospace giants Airbus and Boeing have both been using in marketing their new aircraft, it is fuel efficiency.
But neither of the two major plane makers are directly responsible for much of the promised improvement in fuel usage.
It is in fact largely down to French company Safran and GE, whose joint venture CFM International is making the LEAP motors that will power most of the next-generation of the planes which will be the future workhorses of airlines.
