I'm curious how SD chooses which radio frequencies to show in the PLOG. For example, for my regular journey EGTR-BNN-OX-EGBS, I get every known frequency for Northolt, which is in the opposite direction of travel and is a highly-restricted military airport unlikely to have much GA interest, but no mention of the Farnborough LARS frequencies. Generally, but not always, I find myself having to write the LARS frequencies in by hand.
