Any Analysis is Only as Good as the Data Used in the Analysis

When analyzing a runway or taxiway for accurately assessing its surface characteristics, the type of profile device you use will matter.  If the objective is to perform a smoothness acceptance test on a new runway or taxiway, a high-speed inertial profiler would be the device of choice.  However, if you are investigating long wavelength roughness, something 300 feet (100m) or more, an external reference device  such as APR’s Auto Rod and Level – ER or a device using an incinometer would be the best tools for that job. 

Regardless of what your need is, the key is the ability to measure the pavement’s profile effectively and efficiently.  APR has experience with each of these devices and has measured hundreds of airfield pavement profiles for analysis.  If you need to evaluate your pavement for pilot and passenger complaints for roughness, APR’s surveyors can use our AR&L – ER or SurPRO 4000 to measure the pavement’s true profile.  If you are building a new runway or taxiway and need to evaluate its initial smoothness per P-401 or P-501 in FAA AC 150/5370-10H, APR’s inertial profiler and understanding of these specifications can assist your team.
