Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: 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?

### Accurate SQL ###

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
