ICAO publishes a number of recommendations for the design and operation of airports, including the rate of change of longitudinal gradient per 30 m length of vertical curve.<\/p>\n<p>For A and B type of airports, the ICAO recommendation is that the rate of change of longitudinal gradient per 30 m length of vertical curve should be limited to a maximum of 0.2%. This means that the slope of the runway should not change by more than 0.2% for every 30 m of length.<\/p>\n<p>This recommendation is designed to ensure that aircraft can take off and land safely. A sudden change in slope could cause an aircraft to lose control, so it is important to limit the rate of change of gradient.<\/p>\n<p>The other options are incorrect because they do not correspond to the ICAO recommendation.
