On a VFR flight from Mayerhofen bei Friesach (LOKM) to Zell am See (LOWZ), you overfly Mauterndorf (LOSM) four minutes later than estimated on your operational flight plan (OFP). To which conclusion does this lead?

The wind prediction may not have been correct. A stronger headwind than forecast will lead to around 5 minutes more flight time on the leg from LOSM to LOWZ. The fuel consumption will increase accordingly.

The wind prediction may not have been correct. A stronger tailwind than forecast will lead to around 5 minutes less flight time on the leg from LOSM to LOWZ. The fuel consumption will decrease accordingly.

The aircraft flight manual was not correct about the cruise performance. The other data retrieved from the flight manual, such as take-off and landing performance, should be doubted, too.

The departure time might have been noted incorrectly. As this is the most likely cause for the deviation from the calculated time overhead LOSM, there is nothing to worry about.
