What is the beep after takeoff?

5 Minutes After Takeoff: Two loud beeps of the same tone. These beeps let the flight crew know the plane has reached 10,000 feet. Below that height, there's a regulation that the flight deck only be called for safety-related issues—the sound keeps the cabin crew informed.

All airplanes will be exposed to drag during flight. They must overcome this aerodynamic force to achieve and maintain lift. Otherwise, airplanes would essentially fall out of the sky. Air brakes are control surfaces that increase drag so that airplanes slow down during flight.
