Narrative:

I began to descend below the floor of class B airspace while flying a visual approach to runway 27 at houston's george bush intercontinental airport. The problem arose because I did not refer to the commercial chart 10-1B page for my approach briefing. The situation was discovered by the so, with concurrence by the captain. Corrective actions included leveling the airplane, then utilizing GS information for vertical guidance. Human factors considerations included timely recognition by other crew members and verbal guidance from the captain to resolve the situation. Their assertive monitoring, challenging and guiding skills reflect their ability to apply cockpit resource management techniques to everyday line flying. To prevent a recurrence, I will include a review of class B airspace limits in my visual approach briefings as is appropriate.
