What is V2 in aviation?


What is V2 in aviation? V2: Takeoff Safety Speed. V2 is the minimum speed that needs to be maintained up to acceleration altitude, in the event of an engine failure after V1. Flight at V2 ensures that the minimum required climb gradient is achieved, and that the aircraft is controllable.


Why do pilots say I have the ball?

Later, this was shorted to the “ball.” When an aircraft is on approach in the groove, the LSO will ask the pilot in the approaching aircraft to “Call the ball,” meaning “Tell me when you can see the light.” Answering in the affirmative, the pilot will then “fly the ball,” so to speak, onto the flight deck.


Why do pilots say heavy to ATC?

Wake turbulence poses a major risk to other aircraft, so pilots and ATC use the term “heavy” in radio transmissions as a reminder that the aircraft's wake may be dangerous to others passing behind or below the flightpath of these larger-mass aircraft.


Why do pilots say V1 rotate?

During the takeoff roll, the pilot monitoring the displays (PM) will call out the two important speeds: V1 and rotate. This indicates to the pilot flying the aircraft (PF) when they are beyond the safe stopping speed and when to rotate the aircraft into the air.


Why do pilots say blue?

The callout from the pilots like LOC blue serves to remind themselves of the current flight guidance modes, and to maintain awareness of mode changes. This is also to ensure that their mental idea of what the aircraft will do next is up to date and fits to the current flight situation.


Why do pilots not fly in a straight line?

If every flight took the same trajectory, the traffic would be harder to manage. Another reason why planes fly in an arc is that since it is impossible to fly in a straight line on an airplane, an arc is actually the shortest distance between two points.


Why do pilots say Roger?

(In 1957, the English phonetic alphabet changed the R to Romeo, but by that time, Roger was deeply embedded in the minds of pilots.) So, in short, Roger means r which stands for received. The word Roger means nothing more.
