Appropriate airplane configuration.

Bottom line

Before takeoff, avionics are set with the appropriate frequencies, initial navigation sources and courses, autopilot preselects, transponder codes, and other settings based on the airplane's equipment and flight requirements. As power is brought to full takeoff power, the last check includes confirming the controls are positioned to account for any crosswind. In a go-around, the configuration element means flap retraction, and it comes only after establishing the proper climb attitude and power settings.
