while one engine is being started. The other engine is being dry motor, to get the temp down. This way it reduce the amount of time to get both engine started.

F9 plans us to land around 5k fuel for NEO vs 7K fuel with the CEO, is that similar to what you guys are landing with?

4600 is landing fuel for our NEOs.

There are many things wrong with that statement. Why did you post a response if you knew so little about the system?

seems pretty spot on to me, if you trying to summarize it to someone.

now maybe if you are an engineer from Pratt & Whitney, you could be more technical.

Meh, dual cool. Press button works long time. Also an accurate statement.

Not really a proper explanation of why or how the system works or exists. But I’m proud to show my lack of knowledge of the system on a public forum too.
