FCL.050 certified pilot logbooks

What does it mean for a digital pilot logbook to be FCL.050 certified?

A certified digital logbook meets the requirements of an official standard established and assessed by EASA. It must be accepted by national authorities as proof of experience.

The certification process must be carried out by an officially competent authority and in accordance with an established standard.

This required standard result from the consolidation of various regulations such as Part-FCL, Part-SPO, Part-NCO, Part-NCC, to name the most important.

An FCL.050 certified logbook can replace your paper logbook.

It is from a legal perspective equivalent to a classic paper logbook and may therefore be kept as a stand-alone record.

What must a FCL.050 certified digital pilot logbook contain?

Here is an overview of the standard in short.

Basic requirements

Your logbook will need a very high standard of data security and storage to adequately protect it from data loss (more than one copy and secure servers are just two examples). It is also important to specify the generality of entries across different aircraft categories and simulators.

Format of the record and supported values

Each FCL.050 certified logbook requires specifications for structured data collection for electronic processing. It is also important to have definitions of the relevant data elements for the complete collection of data for the processing of licence entries and endorsements in accordance with the above regulations.

Integrity of the record

Specifications for automatic calculation and structured input of aircraft registration, FSTDs and aerodromes must be included in every certified logbook. All data must pass rigorous validation for plausibility, completeness and accuracy when entered by the user, when imported from external sources such as files, and when stored in the data repository.

Entry signatures

Logbook entries that require signatures and allow instructors, examiners, ATO, DTO, HoT, airports and other parties to sign records must be automatically identified by the logbook. It's important that the signatures cannot be manipulated by the user and that changes to the underlying data are prevented.

Exports / print outs presented to the national authority or its representatives

Certified logbooks must comply with the precise definition of the ability to export a pilot's entire experience in a printable format for licence and endorsement evaluation.

Ask our support team

Is capzlog.aero the only certified logbook?

No. As of today (7/1/2024), there are two FCL.050 certified pilot logbooks worldwide. One is capzlog.aero and the other is the dLogbook provided by FOCA for Swiss licence holders.

Can I easily transfer my data from another digital flight log into capzlog.aero?

Yes and no. We cannot give you a general answer to this question, as it is strongly dependent on the data quality. However, we will be happy to check your data and tell you what adjustments you need to make such that an import is possible. And from that moment on, you no longer have to worry about whether your data is correct or not.

Do I have to keep a logbook as professional air transport pilot?

Flights performed as part of commercial air transport may be recorded by the operator. However, the recording must meet the same requirements, and often companies do not pay much attention to this concern. However, since you are obliged to provide a clean record, it is worthwhile to keep a reliable, independent record yourself.
