Every pilot requires a record of their flight experience
In addition to regulatory requirements, data inaccuracies and errors not only create additional work for regulatory agencies, but also pose potential flight safety risks due to experience-based conditions.
What are the legal requirements for pilot logbooks?
Some of the fields to be recorded are listed explicitly in AMC1 FCL.050 Recording of flight time. In addition, there are a number of data elements that are implicitly defined by conditions in Part-FCL, Part-SPO, Part-SPA, Part-ORO, Part-NCC, Part-NCO and Part-CAT.FCL.050 certified pilot logbooks
When maintaining your logbook, ensure you follow these general guidelines:
Date and times
Crew operation info
Single pilot operated flights
Multi pilot operated flights
Takeoffs & landings
Operational condition times
Refresher training SEP
Familiarization and differences training
Hours (HH:mm) instead of decimal
UTC vs. Local
Keep FSTD sessions separately
Simulator or FSTD experience must be recorded separately. Do not mix their times and other characteristics, e.g. do not count "sim session time" towards flight time/block time.
Common error sources in pilot logbook entries
To maintain the accuracy of your logbook, familiarizing yourself with common pitfalls is crucial. They include:
Miscalculation of time differences
Flight time/Block time/Total Time of Flight: This refers for all categories to the time between two points in time (refer to Flight time). These time differences should be carefully monitored and accurately calculated to prevent discrepancies.
Airborne time: This is the time between Takeoff and Landing. The Airborne time (sometimes called Actual or True Flight time) is the duration the aircraft is in flight, starting from when the wheels leave the runway (Takeoff) and ending when they touch back down (Landing). Misrecording these specific times can lead to errors not only in the logbook but also in other systems like maintenance, accounting and invoicing.
Confusion between distinct time points
Mix-ups can occur when recording values for Off-block and On-block times. Make sure to accurately note these times in their respective fields to prevent confusion.
Additionally, when tracking Takeoff and Landing times, exercise extra caution as these can often be confused or interchanged with Off-block and On-block times. The correct order of the times is Off-block, Takeoff, Landing, On-block. Special care must be taken for flights through midnight where the date changes as well.
Inaccurate calculation of page totals
Each page of your logbook should have the totals calculated for each column, even those that stand at zero. Simple oversights or mathematical mistakes can cause significant discrepancies over time.
Accuracy is critical when calculating page sums. To prevent potential errors, always cross-check your totals.
When introducing 'new' columns, they can become a source of error. Exercise diligence in recording and calculating any newly added categories to ensure their accuracy.
Transferring data to a new page can lead to transcription errors. Always double-check with previous entries for continuity and precision.
Making a mistake here might suddenly put you in a position with way too little experience, which is unpleasant for you, or way too much experience, which might become a serious liability problem.
Be careful not to shift columns during this transition, which could result in recording a value in the wrong category. Ensuring column alignment from one page to the next is crucial for maintaining accurate records.
Misinterpretation of abbreviations and codes
Logbooks often contain numerous abbreviations and codes. Misunderstanding or misinterpreting these codes can lead to inaccurate entries. Regularly review the meaning of these codes to ensure you are using them correctly.
Incorrect date and location entries
The accuracy of date and location entries is vital for tracking flight times and locations accurately. Ensure that you record the correct date and location for each entry. Double-check for common errors, like confusing the day and month in the date format.
Incorrect aircraft registration or make, model, variant
Always write the full aircraft registration, including the country-specific prefix. After some time, it can become difficult to identify and classify the registration.
The type of aircraft must be the one in the official documents of the aircraft and especially engine types, number of engines, required class or type rating may be affected by a wrong type entry.
When must a flight be entered in the pilot logbook at the latest?
Flight crew logbook entries should be made as soon as practicable after each flight. It is recommended that this is done before leaving the aircraft.
Comparing logbook formats: paper, spreadsheet, and digital
In the rapidly evolving world of aviation, pilots are offered a variety of methods to maintain their logbooks. Each method has its own set of advantages and challenges:
Digital Logbook Tools
Digital logbooks have become increasingly popular due to their efficiency and the automation they offer. They perform automatic calculations, reducing the risk of errors in entries. These tools often come with built-in data validation. However, note that different tools offer different level of validation and not all can be fully relied upon.
However, it is essential to understand where your data is stored. Depending on the provider, data can be stored locally on your device, or cloud-based storage might be used. Understanding your digital logbook's data storage method is critical for privacy and data recovery considerations.
Beyond standalone digital logbooks, many tools designed for other purposes such as reservation, training syllabus, and maintenance have started adding 'personal logbook' features. While this might seem a convenient feature, pilots should be wary of using these integrated logbooks as their primary experience record. The need for an independent and personal record that is not tied to any specific software or institution cannot be overstressed.
For those who appreciate a traditional approach, paper logbooks still have a nostalgic appeal. They provide a tangible, personal record of your flying history. They can also be a less expensive option than some digital solutions, and serve as a solid backup method of keeping records.
However, paper logbooks require manual entry and calculation, increasing the risk of errors. They also cannot offer the convenience and features that digital tools provide.
Spreadsheet-based logbooks such as Excel
Spreadsheet-based logbooks like Excel provide a more economical digital solution compared to specialized digital logbook tools. They offer some of the benefits of digital tools such as easier calculations and data manipulation.
However, developing a high-quality, error-free logbook in Excel is not possible. Spreadsheet formulas can be prone to errors, e.g. in some not tested cases, and data validation is not as rigorous as specialized digital logbook tools. In addition, regulatory bodies in some jurisdictions may still require you to maintain a paper logbook alongside your Excel version.
In general, the trend is shifting towards digital logbook solutions due to their convenience, features, and compliance capabilities. However, it is essential to maintain a personal, independent logbook that is not tied to your professional affiliations or the tools they use. Regardless of the method you choose, always keep an eye on regulatory compliance requirements for your logbook.
