Jetliner climbing speed

  1. Apr 14, 2013 #1
    Hi all,

    I am wondering which speed is used for the commercial aircraft to climb after take-off. I have heard that aircraft climbs at constant airspeed until reaching a certain mach number and then continuing with constant mach. Is that the most common procedure for jet aircraft? and what kind of airspeed is it? is it EAS or TAS? Finally, since the engine performance varies with altitude, how can the pilot maintain constant speed while climbing without having to keep adjust the thrust setting? I also know that there is a certain thrust setting for climbing for climb, if so, how can it related to airspeed?

    thank you
