I just did my solo long xc, over 150nm, from one airport, to another, to a third, and then back to home airport. My question is how to put all this in the entries section, do I put all three squeezed together in the "TO" block, which would be my preferred method, or do I split it into multiple lines. Which is the legal and correct way? Can't ask my instructor since he is on vacation this week. Thanks to anyone who can help.
Each flight should go on its own separate line, if you fly from A to B then A is from and B is to. If you fly 4 legs, A->B, B->C, C->D and D->E, landing at each then you'd have 4 lines in your logbook. If you fly from A to E, but pass by B, C and D on the way without landing then you'd have only one entry in your logbook from A to E, and you could say via B, C and D in notes.
Note that there's no legal requirement to do it this way, at least in the regulatory frameworks I'm familiar with, however as you are in training you want to be completely clear on the details so you can demonstrate your flights and times to an examiner, the FAA or anyone else who needs to see it. They will expect to see a separate line for each flight, so it's best to give it to them.
I would recommend that you log them as 3 separate flights for simplicity and clarity.
For example, 14 CFR 61.51 (b)(3) - Conditions of Flight, requires that you record whether the flight was "Day or Night," "Actual Instrument," etc.,). If you squeezed all three separate flights/legs between the "FROM and TO" columns you would have to break this time down somehow, perhaps in the "Remarks" section of your logbook, showing on which flight/leg the Day, Night or IMC time took place. This could become a bit cumbersome and add unnecessary complexity to your logbook. But what ever method you use to record your flight time, I recommend that you do it consistently throughout your lifetime as a pilot.
However, as long as you entered the record of your flights containing all of the required information in accordance with 14 CFR 61.51 (note specifically 61.51 (b)(1)(iii)), you could use the logging method of your choice.
The simplest approach is to log each leg as a separate flight, and that’s completely legal.
However, my personal opinion is that this wastes space for multi-leg flights. Instead, I use a single entry and write all the points of takeoff/landing across the FROM and TO columns, ignoring the divider between the columns.
The regulations arguably say that each time you stop the engine, that ends your “flight”. And that rule is nearly as simple to abide by yet still improves over an entry per leg.
If you do decide to combine legs, the key is to never get yourself into a position where you can forget to log one leg if the next leg gets delayed or canceled for some reason—and the odds of forgetting go up the longer you wait to log it.
