Signs you’ve outgrown the spreadsheet
- The answer to “is this aircraft airworthy right now?” depends on who you ask.
- Dispatch decisions are made in a group chat, with no record of why.
- A medical, licence or document expiry has been caught late, or on the ramp.
- Finding an aircraft’s history or a student’s hours takes days, not minutes.
- Nobody can say for sure who changed a status or a log entry, or when.
- A second base or more aircraft means more copies of the same sheet.
If two or more of these sound familiar, the spreadsheet is no longer saving you time. The cost shows up as a double-booked aircraft, a cancelled sortie or a record you can’t produce when someone asks.
Why spreadsheets break down for flight operations
The trouble isn’t the spreadsheet itself. Flight operations data is connected, and a sheet isn’t. A sortie changes an aircraft’s hours. Those hours change when its next check is due. That check decides whether the aircraft can be booked tomorrow. In a spreadsheet each link is a person remembering to update another tab.
A spreadsheet also has no memory of who changed what. When an aircraft is grounded, the record should show who grounded it, when and why. When it returns to service, it should show who signed it off.
What to gather before you switch
Whatever system you move to, the work starts with the same records. Get these together first:
- 1
Aircraft
Registration, type, current airframe hours and cycles, base, and copies of registration, airworthiness and insurance documents with their expiry dates.
- 2
Maintenance schedule
The checks your engineers track for each aircraft, with intervals by hours and/or calendar, and when each was last done.
- 3
Open defects
Every open snag and any aircraft currently grounded or AOG, with the reason.
- 4
People
Instructors, students and engineers, with licence, rating and medical details and expiry dates.
- 5
Training progress
Each student’s hours to date and current training phase.
Treat this as a clean-up as well as a move. Expiry dates and hours that don’t agree between sheets are worth resolving with your engineers and instructors before they go into any new system.
How to move without disrupting the flying
- 1
Start with the fleet
Aircraft status and maintenance due are the highest-stakes data, so get them right first.
- 2
Add people and expiries
Once credentials are in, expiry reminders start working for you straight away.
- 3
Run both for a short overlap
Keep the old sheet read-only for a few weeks while the team builds trust in the new record. Don’t keep updating both.
- 4
Move daily logging last
When flight logs and snags are entered in the new system, hours and maintenance due update themselves. That’s when the spreadsheet can retire.
- 5
Make one person responsible
A named owner for the move, usually the fleet manager or CFI, keeps it from stalling.
What to look for in flight school software
- Aircraft status that updates from flight logs, not manual entry
- Maintenance due by both hours and calendar
- Warnings at booking and dispatch, not just a report somebody has to check
- Credential expiries with escalating reminders
- A full, exportable change history: who, when, before and after
- Works on a phone, for the ramp and hangar
- Priced for a small fleet, in rupees
