BMS 4.35.1 JFS START 1 Fail all the time. Is a bug??? Perhaps.
-
Starting with JFS START 1 mode fails almost always and I get the impression that it is a bug, please developers check it because the manual says something different, not what actually happens.
-
IIRC chances of fail is 70%
No bug here

You have more luck my friend. It surprises me that in real life it is like that. Maybe it failed due to cold weather, but if it failed at random I do not see it logical.

In real life they never use jfs1
guess why ?
In real this is not probabilistic this is mainly dépendant on wind force and orientation
Will do when I will find the time

THANKSSSSS for all forget my words teacher.

This might depend on the force in question - I recall chatting with an RSAF crew chief on the difference between START 1 and 2 some years ago. I forget which way around he had it… but between the USAF and the RSAF, he reckoned one of them used START 2 exclusively, and the other would use START 1 so they had a second chance to start.

What I have been told is that you have 2 bottles of high pressure to start the engine…
JFS1 uses only one bottle but it requires a good weather and favorable winds otherwise it will fails (that’s why it is never used)…
JFS2 uses the 2 bottles and will most likely work as intended in all weather situation.So yes… with JFS1 you have a second chance but let’s face it, the odds are low to work correctly.

Most pilots are trained to use JFS2. That being said if JFS2 is used, both bottles are depleted. If the engine still does not start they can try again, but the maintenance crew has to hook up a T-handle in the left main landing gear well and pump the hydraulics back up to 3000 psi. They are not easy pumps either….believe me…I have had to do it a hand-full of times and it sucks. If a hydraulic cart or MULE is close by, they can use that too. If it still does not start, it is a maintenance issue and the pilot will have to step to a different jet or cancel his sortie.

Jfs 1 is likely used for airstart because first the wind flow helps and second if your engine fails to start and you have used JFS start2 to try both your accumulator are depleted and you have no more brakes if no more hydraulic pressure
Having 1 bottle left guarantees braking
