Nooch Posted May 11, 2019 Posted May 11, 2019 (edited) Very small issue here. NATOPS p.147 says that zulu time is configured as an offset in plus or minus hours from local time. Problem is right now in the sim it's not displayed accordingly, the plus and minus are inverted. Zulu time is - 4 hours from local Caucasus time and NOT + 4 hours like it is displayed ingame. Here is a very short video showing exactly what I'm talking about. Link here. Edited May 20, 2019 by Nooch Removed a quote to better comply with rule 1.16 [sIGPIC][/sIGPIC]
imacken Posted May 17, 2019 Posted May 17, 2019 I agree that the manual is badly worded there, however, the offset is correct, i.e. the local time is +4 hours from Zulu. It's the use of the word 'from' in 'plus or minus hours from local time' that is ambiguous. The offset from Zulu has to be related to the base Zulu time, i.e. +4 hours.

Nooch Posted May 18, 2019 Author Posted May 18, 2019 (edited) The offset from Zulu has to be related to the base Zulu time, i.e. +4 hours. According to what the Natops says, the offset is actually from local, not Zulu! Actually on the Hornet it's the local time that serves as reference, not the other way around. Hence why, logically at least, it should be -4 hours in this case. Edited May 18, 2019 by Nooch [sIGPIC][/sIGPIC]
imacken Posted May 18, 2019 Posted May 18, 2019 As I said, I think the wording could be better, but as this has been marked as [NO BUG], I'm pretty sure the time must relate to Zulu. Zulu is a constant, and times are always related to it as local times vary. So, it makes sense for the time to be +4 hours from Zulu.

Yes but was it marked as [NO BUG] because of your initial response or because they got the word from their SME? You could be wrong, I could be wrong... I guess only somebody who actually sat in a Hornet cockpit could be able to tell for sure and that's what I'd like to know. [sIGPIC][/sIGPIC]

Caucasus time is UTC(aka GMT)+4. No rocket science there. https://en.wikipedia.org/wiki/Time_zone Check Georgia time zone. Russia UTC+3 in the same area, that's related to political choices. S!

Nooch Posted May 18, 2019 Author Posted May 18, 2019 I already know what Zulu time is, thank you. The thing is, the Hornet doesn't care if you think Zulu is the reference or not. Hornet's reference (from the computer point of view) is local time not Zulu. I haven't invented it, this is what's written in the Natops. Also you can tell it was engineered that way in the jet because you can set up local time but not zulu. Zulu can only be selected as an offset from local time. [sIGPIC][/sIGPIC]

Look, you may be right, or you may be wrong, but, in my opinion, it would make no sense to make local time the reference and for the Hornet to calculate Zulu time from your input. I mean, what if your input was incorrect? Zulu would be wrong which is a nonsense. Zulu time is fixed and the Hornet computer must know it! It surely must be up to the pilot to state the local offset from Zulu. No matter where in the world the aircraft was, it should always know Zulu, and the pilot can input the offset for local time.

Yes, logically, from our point of view, it should have been designed like you just described. However, as stated in the NATOPS and as you can see by yourself if you go set up time in the IFEI, it is the other way around in the Hornet. Why? I guess we'll need to ask a Boeing engineer or some navy expert in order to know. [sIGPIC][/sIGPIC]

NATOPS can be wrong indeed, or just wrongly worded, anyway nobody cares since it's not a legal source, right? :lol: S!
