A powerful feature of RB Logbook is the ability to create filters. These filters can measure a currency or limit, e.g. EASA or FAR limits. You can also define an achievement.
The way these filters are defined, can seem complex at first, but it is very flexible. We encourage you to try it out. If you have any questions, our customer support team is there to help you out.
When creating a new filter, you are asked to specify a filter query. This has the format that resembles SQL.
SELECT Total Block
WHERE Date Within The Last 28 DAYS
This filter will keep track of the EASA limit ORO.FTL.210 (b).
Let's break it down.
SELECT is used to specify the value you want to track. In this case the Total Block time.
WHERE is used to specify under which condition flights will be included in the filter. In this case we define that the date should be 28 days ago until now. You can define multiple WHERE conditions.
MAX defines the limit. In this case 100 hours. When this limit is almost reached, you will be notified by the app.
