What is the aggregate flight data entry page for? How is it different from the normal logbook entry page?
The aggregate page is for entering large amounts of flight data in one entry. It does not break out individual flights and is not intended to contain individual flight data. Rather, it is a summary entry of flight time from another source (such as an old logbook, for example). You may want to create an aggregate entry so all your flight time is accounted for when you view all of your flights, however it’s up to you whether you use it or not. There is no limit to the number of aggregate entries. Also, aggregate entries are not used in any flight time calculations. The only way you will see aggregate entries is if you “view all entries” in your logbook. All searches and other calculations ignore aggregate entries since it is not possible to deduce the combinations of flight times from this kind of data.
