How to get the most out of LogTen Pro's airport management features
In LogTen Pro you can manage a database of airports. When you enter a From or To value for a flight it searches for a match in the places database (the Places tab). If it doesn't find one it will search the internal database of over 27,000 places worldwide; if it finds a match it will create a new entry in your places list and copy the data from the internal database. If the field is STILL not found it will simply create a new empty entry in your Places tab and set its identifier to whatever you entered in the "From" or "To" field.
The "From" and "To" fields are much more than just a few characters, they link to a specific place that allows LogTen Pro to do things like calculate the distance of your flights, instantly change how your "From" and "To" fields are displayed (in the Preferences you can select from Identifier, ICAO, IATA, or Name), as well as setting up a reverse relationship to every flight that uses that location so that you can look at a particular place and instantly see how many arriving and departing flights you have.
From and To places should always be a single identifier. Route information should be entered in the "Route" field.
Many pilots like to record a day's flying as a single entry, and it is not uncommon to see a sequence of sectors in the "From" or "To" field. For example on a flight from Denver International Airport to Seattle's SeaTac Airport via Los Angeles International and Phoenix Sky Harbour you might see something like this in the "From" field: KDEN-KPHX-KLAX and then KSEA in the "To" field. As you may have already guessed from the first paragraph, this will result in a new airport being created in your list with the ICAO ID of "KDEN-KPHX-KLAX": this is not ultimately helpful, since the next time you go to enter a flight to KPHX, you'll get "KDEN-KPHX-KLAX" auto entered because it found a match!
So, the way we have designed LogTen Pro, you need to enter the starting point, and the end point in the 'From' and 'To' fields and then enter route information in the 'Route' field. Note that at any time you can choose "Get Place Data" under the Manage menu to fill in missing data from the internal database where available. This means that if you've got an airport with just an ID, such as KDEN, running this command will look up KDEN in the internal database and fill in the IATA, the Name, Lat, Lon, City, State, Country etc. whenever that information is available.
If you've got a bunch of data entered in this fashion, and you need to clean it up, the best thing to do is export your flights to tab delimited file, then open it in a spreadsheet application like MS Excel for cleanup. Here you can create a calculated field to just grab the first identifier from your list of fields ("From" in our example above) and make a new, single identifier, "From" field. Then you can import your data back into a new empty file in LogTen Pro importing the old from information into the "Route" field and your new "cleansed" from information into the "From" field.
