Context: CREATE TABLE table_name_19 (max_height__ft_ INTEGER, time_to_ft__m__at_55°__seconds_ VARCHAR, m_v_ft_s VARCHAR)
Question: What is the average maximum height of a shell that travels for more than 16.3 seconds at 55° and has a maximum velocity of 2200 ft/s?
Answer: SELECT AVG(max_height__ft_) FROM table_name_19 WHERE time_to_ft__m__at_55°__seconds_ > 16.3 AND m_v_ft_s = 2200
