Viewing and Exporting Logs

Overview

The Flight Logs page is more than a place to submit new entries — it's the authoritative record of how your club's aircraft have been used, and it's designed to make that record useful in the ways that matter most. Filtering lets you focus on a single aircraft or a specific pilot. Date range controls let you zoom into the billing period you care about. Tach continuity checking catches missing entries before they cause problems downstream. And CSV export puts the underlying data into the format your accountant, your mechanic, or your insurance broker can actually work with.

Consistent, well-maintained flight logs are what allow a flying club to operate with confidence. When the maintenance team needs to know how many tach hours are on the engine since the last oil change, the flight log is the source of truth. When a member disputes a billing charge, the log provides the evidence. When an insurance renewal comes around and the underwriter asks for a utilization report, the export is how you provide it. None of that works without accurate entries — but assuming the entries are accurate, this page is where their value becomes visible.

Flight Logs require the Time Tracking feature to be enabled for your organization. If you don't see Flight Logs in the navigation, contact your club's account owner to confirm the feature is active.

Filtering the Logs

The logs table opens defaulted to Last 30 Days across all aircraft and all pilots. Three filters at the top of the page let you narrow that view:

• Filter by Aircraft — Select a specific tail number from the dropdown to see only entries for that aircraft. The filter persists in your browser's local storage, so if you navigate away and come back, the same aircraft will still be selected. Select All Aircraft to clear the filter.
• Pilot — Filter by a specific club member to see only their entries. This is useful for reviewing a member's flight history or compiling individual pilot logs for review.
• Date Range — Choose from Last 30 Days, This Month, Last Month, Custom, or All Time. Selecting Custom reveals two date pickers — set a From and To date to define an arbitrary window. The date range filter works together with the aircraft and pilot filters, so you can ask for, say, all of Jane's flights in N12345 during March.

At the bottom of the filtered table, Centerline shows the Total Hobbs and Total Tach for the current filter — the sum of all elapsed times across every visible entry. These totals update immediately as you change filters, making it straightforward to answer questions like "how many hours did we put on the Archer last month?"

Tach Time and Aircraft Status

When a log entry is submitted with an End Tach value, Centerline updates that aircraft's current tach time in the fleet status system. This is what drives tach-based maintenance interval tracking — oil change intervals, 100-hour inspection countdowns, TBO awareness, and any other schedule your maintenance team has configured against tach hours.

This means the integrity of tach time in the maintenance system is only as good as the flight log. If entries are missed, partial, or entered with incorrect tach readings, the maintenance schedules will drift out of alignment with the aircraft's actual state. Encouraging members to complete both the start and end tach fields on every entry is one of the most operationally important habits a club can build.

Gap Detection

When you filter the table to a single aircraft, Centerline performs continuity checking on the visible entries. If the Start Hobbs or Start Tach on one entry doesn't match the End Hobbs or End Tach from the previous entry, Centerline inserts a highlighted gap row between the two entries. The gap row shows how much unaccounted time exists, flagged in orange with a warning icon.

Gaps usually mean one of three things: a log entry was forgotten, a partial entry (no end values) was submitted and never completed, or a meter reading was entered incorrectly. To resolve a gap, click the + button on the gap row. Centerline will open the New Log Entry dialog pre-filled with the expected start values and the next entry's start values as the end values, bridging the gap as cleanly as possible. You can adjust any values before submitting.

Gaps aren't just a bookkeeping issue — an unresolved gap represents time the aircraft was flying that isn't in the log, which means tach-based maintenance intervals may be understated and billing records may be incomplete.

Phantom "Next Entry" Row

When you filter to a specific aircraft, Centerline also shows a Next entry row at the very top of the table. This row displays the expected Start Hobbs and Start Tach for the next log entry — pulled from the end readings of the most recent entry for that aircraft. Click the + button on this row to open the New Log Entry dialog pre-populated with those values, making it easy to start a new entry without having to look up where the gauges last left off.

Exporting to CSV

The Download CSV button exports the currently filtered set of log entries to a CSV file, which you can open in Excel, Numbers, Google Sheets, or import into accounting and maintenance software.

Who can export: CSV download is available to members with the ACCOUNT_OWNER, BOOKING, or MAINTENANCE role. Regular members (MEMBER role) can view the logs table but cannot download the export. This restriction reflects the sensitivity of full fleet utilization data, which includes every pilot's flying activity.

What the export contains: Each row in the CSV represents one log entry and includes the following columns:

Column	Description
Date	Entry date and time, formatted in your organization's timezone
Aircraft	Tail number
Aircraft Type	Make and model
Pilot	Pilot's full name
Start Hobbs	Hobbs reading at engine start
End Hobbs	Hobbs reading at engine shutdown
Hobbs Time	Elapsed Hobbs hours (End minus Start)
Start Tach	Tach reading at engine start
End Tach	Tach reading at engine shutdown
Tach Time	Elapsed Tach hours (End minus Start)
Maintenance Flight	Yes or No
Fuel Added	Gallons added, if logged
Oil Added	Quarts added, if logged
Comments	Free-text notes from the entry

Filename format: The downloaded file is named automatically based on the filters in effect. For example, filtering to N12345 with a date range of March 2025 would produce a file named flight-logs-N12345-2025-03-01-2025-03-31.csv. This makes it easy to keep multiple exports organized without renaming them.

Filtered exports: The CSV reflects exactly what you see in the table — if you filter to a specific aircraft and a custom date range, only those entries are exported. Apply your filters before clicking Download CSV to produce a purpose-built report. To export the complete log history, set the date range to All Time and leave the aircraft and pilot filters on All.

Tips

• Export monthly for bookkeeping — Set the date range to Last Month and export at the start of each month to create a clean billing-period record. File the CSV alongside your invoices or share it with your treasurer.
• Use aircraft filters for pre-annual review — Before each aircraft's annual inspection, filter to that tail number with date range set to All Time to give your A&P a complete picture of the engine's usage history and any logged anomalies.
• Check for gaps regularly — Make a habit of filtering to each aircraft once a week or after a busy flying weekend to catch and resolve any gaps while the flights are still fresh in members' memories.
• Export before purging or migrating data — If your club ever transitions systems or archives older data, download a full All Time CSV export first to preserve the historical record.
• Maintenance role holders should audit tach continuity — Because End Tach values feed directly into maintenance scheduling, anyone responsible for the maintenance program should periodically review the logs for each aircraft to ensure tach readings are continuous and plausible.
