My friend told me at 80knots you call out 80knots then V1 VR then rotate then V2 possitive rate gear up

I thought you said 80 knots V1 rotate V2 possitive rate gear up i dident think you said VR I thought it ment rotate


Who is right?

he told me that you callout VR when the front nose gear lifts up

80, V1, Rotate, V2

Positive Rate, Gear Up

Gear Up

I like to tell my FO a quote that I heard,
"Either of us can call abort for any reason before 80 kts, after 80 we only stop for engine failure or fire, V1, were goin flying..."

The main reason to call out 80 Knots or 100 knots is to acknowlege that the aircraft is entering a high speed band. Above this speed, if some minor things occur it is better to not abort the take off. V1 is the main decision point for ALL abnomalities.

At V1 the pilot must start to action the aborted take off if he chooses to do so. The allowance is V1 + 2 seconds and then the aircraft must be in the aborted configuration and power settings

Vr is rotate and V2 is the safe climb out speed.

The 80 knot thing however differs from company to company, dfifferent SOPs will tell pilots slight variations

I'm used to calling out 50 KIAS, that is the minimum that is indicated, cross check pilots and copilots indicator for less than 5 knot difference. It is also when the Rudder Pedal steering becomes effective. At that point the pilot can take left hand off the nose wheel steering and put it on the yoke.
Then Vrot, which is Rotation speed or Vr which is Refusal speed, which ever comes first.
Vrot if you have a split marker. If not Vr is irrelevant.
Positive rate of climb.
Gear up.
VMFR, climb at that speed until clearing any obstacle.
Then Flaps up.
Set climb power.

its 80 knots v1 Vr gear up and v2


v1--the minimum speed at which an aircraft pilot may continue a takeoff after the failure of the most critical engine

vr---takeoff

gearup or positive rate of climb duhh

v2 the speed where an aircraft accelerating on a runway must lift-off

Interesting question, in that there is not a standardized saying among companies and services, though some of the speeds called out are similar.

For the Navy P-3, the sequence goes like this:

Non-flying pilot:
"80 knots"
"Refusal" (if aircraft weight is heavy enough -- analagous to V1)
"Rotate"

Flying pilot:
"Positive Rate of Climb"
"Gear Up"

Non-flying pilot:
"Gear selected up"
"Gear coming up" or "Gear in transit"

You are correct. Some pilots say "VR", some say "rotate", but never both. I always say "rotate". And it's always said at a certain speed (usually a few knots above V1) and then the flying pilot rotates.

I know you guys talking about big planes, but in my training, we use C172, and we callout "airspeed alive" first, then when it reach VR, and when we start rotating, we call "rotate".
As it climb, says "positive rate" and clear obstacle, we pitch for VY, said "positive rate".
If its a retractable gear may be theres another callout, it just depends on the plane you fly, the company you worked for(if you fly for a job), and some others. But usually its technically the same.

Some companies have you say "Airspeed alive."

Some companies have you say "V1," "Vr," V2." Others say "V1," "Rotate," "V2." "Vr" isn't a command to rotate. "Vr" is a callout--an advisory.

Some don't have the "V2" call.

Some say "Positive climb."

Some have the flying pilot say "Gear up."

Vr is rotation speed. So you could say Vr or you could say rotate but you don't need to say both.

Most companies actually have detailed procedures regarding the information that the non-flying pilot will call-out for the flying pilot.

If you can rotate at 80 knots you are in a small aircraft. I usually say something like "here we go sweetheart" in my little 310. Call out implies a copilot and or a nav which small planes dont usually have.
