Global Reporting Format, GRF, new regulations, etc. I´m sure you have heard all about it already. We have written multiple blog posts for this topic, also ACI and ICAO have done lot of good work to spread the word. This information flow has also got many confused what are our needs at the airport after the new regulations. What equipment is used, and which software is needed? Now there´s a need for fulfill all these new requirements from the users, can one equipment do it all successfully?

We have built one of these so-called all-in-one machines. These products have been developed individually but we have done lot of work to put up a packet which fulfills all the needs at any airport runway inspection. The solution is Skiddometer BV11 Vehicle Integrated equipped with contaminant sensor and Global Runway Reporter software. The goal has always been making runways safer with high quality equipment in a way which is still user friendly. Let´s look deeper in to the runway inspection needs at airports with different climate.

Operational needs

Airports around the world faces challenges due to changing weather conditions and are in a need of tools helping report these conditions to the pilots. We are not only talking about snowy or icy conditions, but this can also be rain. The conditions can be such that no maintenance actions can make the runway dry which means that according to GRF the actual conditions need to be reported.

Reporting the runway usually means inspecting the runway by driving it through. When using our Skiddometer BV11 friction tester while the visual inspection, friction is easily measured. This friction value can be correlated to Runway Condition Code from 0 to 6 (more information about this can be provided by request) and used for total assessment of the surface conditions, especially with up- and downgrade.

The correlation is shown in the friction graph and color coded to the map.

The contaminant type, coverage percentage and depth are essential part of runway reporting. This is done usually with human eye but sometimes the conditions are challenging for that. We can help the inspector to recognize the contaminant type and record a memory backup for the whole runway length. With water, we also get the depth of water film to be able to recognize the important 3mm water limit for standing water. The sensor can be equipped with surface temperature and dew point information. We have set up a view which is intuitive for the inspector to see all this information.

Contaminant data is shown in graphical format and on the map with color classification.

Now we have gathered information from the surfaces, logically the next step is to report these runway conditions. We have introduced our Global Runway Reporter software for this purpose. The software is running on the same measuring computer and by just one click you can report all necessary information. Based on our observation and measurements, we can select correct Runway Condition Code (RWYCC) for landing aircraft and correct contaminant for taking-off aircraft (more information of take-off from here).

Software is designed in a way that when sending the report from the Skiddometer BV11 vehicle, it goes directly to relevant networks, such as AFTN or AMHS. Preferably also ATIS is automatically updated based on our ATIS output. The delay is generally only seconds which increases the operational safety as the pilots gets the latest conditions immediately after the inspection. The way of handling this information flow varies country by country and we have been managing doing it for all our customers.

Maintenance needs

With maintenance, we focus on runway polishing, drainage, and rubber build-up problems. This is inspected with Skiddometer BV11 friction tester with watering system. The vehicle has everything on-board regarding wet friction testing: over 600 liter water tank, electrical water pump, special nozzle and computer controlling the water flow to be constant 1mm at all speeds. We determine the friction levels by doing friction testing on relevant distances from the centerline. If we reach minimum limits for the friction values, we should do corrective actions as soon as possible.

Meanwhile, if friction is under the minimum levels, we should use contaminant sensor to monitor if the surface is wet. In this case, if we recognize that significant portion of the runway is wet, we need to report Slippery Wet conditions from the runway. Again, we can use our Global Runway Reporter software to report these conditions and publish Runway Condition Report.

All-in-one

Considering the above, it´s safe to say that all-in-one solution in this case works perfectly. The vehicle can be used around the year regardless of the climate conditions. It fulfills all the needs to comply with GRF and help the runway inspectors challenging work. Top of all this, the vehicle model and software outputs can be selected based on your regional needs and regulations. Can it get better than this? Get yours now simply by contacting us.
