You claim it was ash cloud but do you have the chemical analysis of whatever it was they were dropping for us to see along with the chain of custody?
The ash used in the test was from the 2010 Eyjafjallajokul eruption. It was collected and dried by the Institute of Earth Sciences in Reykjavik. easyJet then collected it and flew it to Toulouse.
The ash, which was the consistency of fine talc, recreated accurately the conditions of 2010. Creating an ash cloud provided the team with an advantage because they knew exactly how much ash was in the atmosphere.
- lol See how easy it is whenever someone claims 100% proof of anything?

Exactly the opposite I would have thought - the OP remains to highlight exactly where the goalposts aer for this thread.
Did you mean to offer some actual evidence or comment on the content?

indeed if moving the goalposts means posting facts ahead of the chemie's using youtube videos and ignorance for arguments….

really? and since when is the OP the authority beyond all appeal and dispute here?
did you mean to provide any additional evidence or comments on the content?
[other than the usual pusillanimity and sniping, perhaps a link to contrailscience?]

It was a problem more with the FADEC more than the engines, although a couple problems did crop up that were solved pretty quickly. They began deliveries last month or so.
True full authority digital engine controls have no form of manual override available, placing full authority over the operating parameters of the engine in the hands of the computer. If a total FADEC failure occurs, the engine fails. If the engine is controlled digitally and electronically but allows for manual override, it is considered solely an EEC or ECU. An EEC, though a component of a FADEC, is not by itself FADEC. When standing alone, the EEC makes all of the decisions until the pilot wishes to intervene.
FADEC works by receiving multiple input variables of the current flight condition including air density, throttle lever position, engine temperatures, engine pressures, and many other parameters. The inputs are received by the EEC and analyzed up to 70 times per second. Engine operating parameters such as fuel flow, stator vane position, bleed valve position, and others are computed from this data and applied as appropriate. FADEC also controls engine starting and restarting. The FADEC's basic purpose is to provide optimum engine efficiency for a given flight condition.
FADEC not only provides for efficient engine operation, it also allows the manufacturer to program engine limitations and receive engine health and maintenance reports. For example, to avoid exceeding a certain engine temperature, the FADEC can be programmed to automatically take the necessary measures without pilot intervention.
