Take Off Roll Call Outs

Fri Mar 03, 2006 11:25 am

I have a quick question for any Pilots (or people who know way to much about aviation to not be a pilot). . .

As the flight crew advances an airliner down the runway, what is called out just before "V1 Rotate" and what is called out just after "V1 Rotate?"

Thanks in advance for your responses.

"V1" and "Rotate" technically are seperate callouts. :p


Perhaps the callout you are talking about is the one for 80 kts. That is when the rudder becomes active.

Thats true, they are seperate call outs. Im just wondering what is the call out right before, and right after.

Is it "V1" "Rotate" "V2"?

and if so, what does V2 mean?

Callouts of "airspeed alive" followed by "80 knots ... V1 ... Rotate (some say 'vee are') ... V2" are pretty much standard on all flight decks from what I've seen.

V2 is the minium safe climbout speed. The aircraft can fly after this speed.

V1 = maximum speed that a takeoff may be aborted if an engine is lost.
Vr = speed at which rotation should occur
V2 = minimum flight safety speed. This is the minimum speed that will allow the aircraft to climb out on one engine.

There are many, many other V speeds as well, but that's not the scope of this thread.

The call outs also vary greatly from company to company.

On the 727 and ERJ for ex, V1/Vr were/are typically the same number - unless a V1 reduction is made. This would be due to a contaminated runway, for example, in which an earlier decision speed helps mitigate the probability of executing a rejected take off.

That's true, we just make the 80kt call, V1 and rotate, no V2 call in the MD-11.

V speeds are figured from performance tables set by the manufacturer. I've never heard of 'airline specific' speeds.

Goldenshield, here are 2 examples...

Embraer certifies and flys the ERJ in the landing config at the top of the white arc for an approach speed. Most ERJ operators in the US add 5-10 kts to this value for their ref and target speeds. This varies from airline to airline. Cont EXpress, before the XJT days, was white arc plus 10 for both values (which were separated by 5 kts). About 3 years ago, they went to "white arc" plus 5 kts due to the fact that 5 kts makes a big diff for a transport category a/c in terms of landing distance, which corresponds to revenue. Because these values were published in FAA approved manuals, the new values had to reapproved by the FAA, but are certainly airline specific.

Northwest uses:

100

120 (if needed)

140 (if needed)

Vee one

Rotate, ## degrees

Positive rate
gear up

Most airlines use Aerodata now anyhow, and since they are FAA approved, it's pretty much irrelevant anymore. :P

5 knots makes a big difference in terms terms of landing distance, which corresponds to SAFETY.

The 2nd example is takeoff performance...Boeing never published a comprehensive, reduced thrust takeoff profile for the 727. Why? Because it was fleet specific. NWA had a fleet that consisted of a/c from several manufacturers (Hughes Airwest, Republic, Eastern, etc) with thrust combinations that were too expansive for Boeing to consider. NWA used JT8D-9s, -15s, -17s, and 17 Aprs... and was approved for an Intermix for those engines, meaning an a/c could have 3 different dash types on the same a/c.

If you've followed this so far, then you'll follow the rest. That variation was airline specific, therefore the V speeds were as well. Not a huge difference, but a significant difference...

Goldenshield,

So now maybe you agree w/ me? What's the biggest gag in the crewroom when the weather's bad?

"How's the weather at XYZ? Doesn't matter...we GOIN' anyhow!!!"

The airline business is based on $$$....the safety part comes from crews, maintenance, dispatch and ATC, among others...

I THINK what the post is referring to is what CALLOUTS do airlines use. This would/ could be airline specific. I can say that here we used to call 80, V1, rotate,positive rate AND V2 in the 727; in the MD-11 we don't call V2 because the FMS is going to guide you to V2+10 with all eng and V2 with an eng. out so it's a superfluous call. For app/ldg there are no airspeed calls(for us) except "Betty's" calls at 500', 50, 40, 30, ..etc.

Some callouts I have seen while riding as an observer on the DC10-30:

PIC: "Auto throttles on set take-off thrust."

The FE will then watch the throttles and engines to make sure they are at the proper TO thrust setting per the TRC when it is verified the FE calls out: "thrust set"
CAN DO!

I think you may be right. It's all a matter of interpretation to what was said.

Golden's right. It's all about getting out of the trip. Unless it's the last day, then it's all about finishing early.

We have:

set thrust.... thrust set
80 knots... check
V1
rotate
V2
Positive rate.... gear up

The rest are Flight guidance callouts. Speed mode at V2+10-15, Heading or Nav mode at 400 feet, and the autopilot becomes and option at 600 feet.

I presume (with a name like mine I can presume) that's Speed Mode between V2+10 and V2+15, rather than V2-5? (Pardon the ignorance!)

During the takeoff roll it is better to have a quiet cockpit apart from the very important call outs :
Ready to go, the captain announces "Takeoff, V1 is xxx kts"
Once the thrust is set PNF announces "parameters stable"
PF calls out the FMA "Man Flex XX° SRS RWY NAV and A/THR armed "
PNF :
-100Kts (for ASIs xcheck and the signal that from now on we'll only reject for an engine failure or a severe structural damage)
-V1
-Rotate

In the US it's typically called a "sterile cockpit." Some airlines use "parameters stable" others use "thrust set, xx.x%N1". The takeoff profile callouts will vary with different thrust settings, flap settings, even MELs/CDLs...

The takeoff callouts are really airline specific. For example, on the 744, the calls vary from a few airlines I've been involved with. For instance, some airlines call "hold" and "80 knots" as two distinct calls, while others have it as one call. The V1 and Vr calls are fairly standard and most have no calls after Vr. But again, that's airline specific.

I respectfully disagree. Did you take the time to read the entire thread? I think it's been rather well made, with examples, and in fact you restated a comment I made 22 posts ago.

Like I said, judging by the comments, people either didn't read that or just didn't care. I didn't know this forum was restricted to one correct response?

Sometimes, people have to have the same response either repeated verbatum or rephrased.
