would be nice to be able to manually add frequencies to the printed PLOG, both COM and NAV, to cover such missing ones.

I now print SD PLOG for every flight I do and noticed a couple missing that I would like to have had (Solent Radar (inc listening squwak), Farnborough W (as well as east), SAM VOR etc) Obviously there is a space to write them in, but none the less having them printed all together would be very nice!

Thanks for the explanation.
I always use printed datasheets for airfields (VACs for France etc.) so knew what the frequencies were, but just surprised that they weren't in SD briefing.
I am not familiar with how SD gets their data for inclusion in the application but had assumed that if a frequency was listed on a SIA VAC datasheet it was  probably "in the database" that SD has access to.

If you look at the SkyDemon information for both those airfields, you will see we do not hold frequency information for them. So naturally, we cannot include it in the PLOG!

I believe it is our policy not to include A/A frequencies explicitly when they exist country-wide for every airfield without their own frequencies.

My planned route passed within 1-2 NM of Berck. Also, as mentioned, no frequency shown for my planned destination of Abbeville.

There is an algorithm to determine whether various airfield-based radio services are displayed in the PLOG which depends upon how close your route passes to the airfield in question. A/A in France are definitely included but probably only if your route passes quite close to the airfield (a few miles).

I have planned a flight to Abbeville (LFOI) and my route passes very close to Berck sur Mere.
Although I know the radio frequency for both these airfields (A-A 123.5) I am surprised they aren't listed at all in the pilot log.
I tried another route to a UK airfield with AFIS and the frequency is shown correctly.
Are French air-air frequencies ignored in the PLOG?
