Close to getting his first certificate in normal operation, the CFM issued a recommendation for the Leap 1A engine start time. According to the manufacturer, it is necessary to conduct the startup procedure of the motor for 50 seconds before taking the first ignition. This recommendation was also passed to the Airbus, which now expects to offer the A320neo with Leap 1A engine until the end of the first half of 2016.
Recently Pratt & Whitney launched an update package, which will be available later this month for its PW1100G engine that equips the A320neo, the driver of PW required three minutes to spool-up before you start your ignition, leaving the first customers uncomfortable with this requirement and caused by the exchange of launch customer for the aircraft. Qatar refused to receive the first A320neo with such characteristics, leaving it to the Lufthansa has agreed to be the launch customer.
In justification of PW your new generation of propellant needed more time to warm parts also before going into operation, but this will only happen if the engine stayed off for 1:30 a.m. to 2 hours continuously. The problem will be solved by the end of this month with two updates, one that reaches the propeller control software, and one that affects the physical part, which will happen upgrades axis parts.
CFM says its new engine will not suffer from such consequences in the start-up time, as the Leap 1A is described by them as "like CFM 56" due to its design minimize the Question of start-up. Recently the Boeing 737 MAX 8 held its first flight equipped with Leap 1B engines, suitable for the fan size required, meanwhile Airbus continues testing at its A320neo aircraft equipped with Leap 1A, with larger fan diameter when compared to 737 MAX.
The CFM Leap 1A received dual certification from the FAA and EASA on 20 November last year. The project time was the longest so far conducted by CFM engines were 34, 6500 hours of testing and 13,450 use cycles before equip the A320neo and 737 MAX aircraft.
Nowadays the 1X Leap engine is designed to go into service on Airbus A320neo aircraft, Comac C919 and Boeing 737 MAX, the last two being the default engine purchase.
