Hi people!Little problem: when I use the 737-800 Ryanair I hear two V1 calls, with two different voice tones. The first V1 is called just few before the correct velocity while the second is called AT correct velocity.Last,when I use the KULULA's 737-800 only one V1 in called.Can you help me?Thanks.Emanuele

Sounds like you have FO callouts enabled

That is normal, and can be adjusted I believe.. One of the V1 calls is the pseudo F/O.The other one is the airplane itself calling it out. I think those can be toggled off and onin the CDU. I leave both of mine on. How those are used will vary to the company I think.

V1 is the maximum speed at which you must take the first action to reject a take-off if you want to safely bring the plane to a stop without running off the runway (in a critical runway length scenario). That means if you only decide to reject at V1 you will take the first action about a second later, at which point you will be above V1 and thus overrrun. Hence a number of airlines now have it as their policy for the pilot monitoring (PM) to call V1 5 knots prior to reaching the actual V1. That way if the pilot flying (PF) decides to reject the moment he hears the V1 call the first action will still take place before or at V1. The plane itself will call out V1 at the actual V1 speed set. Which call-outs you get depends on the aircraft options you (or the livery maker) have set.Some airlines have adopted the practice of calling 'Go' instead of 'V1' at the V1 speed, but I'm not sure if that's an Airbusism.

It was added in SP1b

where can i unable the rotate call, it had called by the time the v1 is called

Same place as you enable/disable the calls..FMC->Menu->PMDG Setup->simulation (I think - I'm at work!)

thanks, i have looked for it there without luck, thanks anyway(:

FMC > MENU > PMDG SETUP > AIRCRAFT > EQUIPMENT > and then look for a page with all callouts.( I am also at work but I've got the 737NGX's pdf's on my computer... :( Still can't check if the setting you need is actually there...)

Oh the things that could be solved if people paid attention to the release notes in SPs, and simply went searching for themselves in the settings...Maybe it's just me...

+1But I don't like to post 'RTFM'... :( so I always look it up for them. I'm too good for this world. :( But it's true: it's amazing that there are so many question of which the answers can be found in the pdf's... People don't seem to know that you can SEARCH pdf's? :(

probably you are in reason but - for me . the main question is: WHY TWO V1 calls?We need ONLY ONE v1 call and ONLY ONE Vr call.To the user only the possibility to hear or not to hear the calls; in few words ON/OFF calls... and stop!So, returning to thread... why I hear TWO V1 calls?

Your question was already answered by a few people.PMDG added the F/O callout 5 knots before V1 in a service pack. The airplane itself calls out the actual V1, Vr, V2..You can disable the F/O callout in the EQUIPMENT menu in the FMC.

To answer your question directly, some airlines dictate (in their SOPs) that the pilot not flying (PNF) call out V1 approaching V1. As V1 is passed, the aircraft will also announce V1. It's a company option on both accounts.
