Hello, I found some issues. But hey, only these!
I verified all airfields in Finland and read finnish AIP to found these.

THE LEVEL OF VFR FLIGHTS
4.5 VFR is fixed in FPL.
https://ais.fi/ais/vfr/gen_en/flight_plans.html#1003270

12.6 missing airfields, eg. EFMN, EFLL, EFLN, EFPA, EFVL, EFVP, EFVI
https://ais.fi/ais/vfr/aerodromes/aerodrome_toc.html

1.3 Missing FIR sectors, 1-7 FIR sectors
https://ais.fi/ais/vfr/gen_en/airspace_classification.html#1010287
and sector frequencies. See "TAMPERE RADAR" in
https://ais.fi/ais/vfr/gen_en/air_traffic_services.html#1003963

1.2.1 Missing Protection zones eg. around EFFO
https://ais.fi/ais/vfr/gen_en/airspace_classification.html#1003418

Closed RWs are missing like EFHJ, EFHI, EFJP, EFMP, EFVU
See link.

Missing noise abatement area around Helsinki downtown. See VAC.
https://ais.fi/ais/eaip/aipcharts/efhf/EF_AD_2_EFHF_VAC.pdf
There are several abatement areas in Finland. Above is one example.

Missing two protection zones for industrial plants.

Nice to have feature
-Visualize upper air sounding balloons mentioned in the previous link. Would be nice if wind direction is used to shade probability of area where it might be.
- route warnings about bird migration. See.

I do not understand how the link to the level of VFR flights is relevant to SkyDemon.

Example: I'll fly EFHF-EFTU and like to climb A065. It's controlled class C airspace. If I fill Cruising Level as VFR in FPL, ACC don't know my wish to fly A065. There is instructions how to file this wish in FPL.
See.
FPL instructions main page and Instructions PDF. Page 10, ROUTE(Item 15), (b) Cruising Level

This is a common mistake.

In a VFR FP - and that is what SD is about - you can not specify a crusing level other than VFR.

In a VFR FP - and that is what SD is about - you can not specify a crusing level other than VFR.

Where do you get this information? I certainly have files VFR flightplans giving a definite cruising altitude. Also, in some places I have been requested to enter my initial cruising altitude, no matter that I was flying VFR.

So it seems that different ATC units prefer things to be done differently.

In Denmark a VFR flightplan will be rejected if the level is other than VFR.

Here an extract from the Danish VFR Guide:

3. Completion of the flight plan item 15 in connection with VFR-flights within København FIR, the following specifications regarding level and positions apply:
- irrespective of which class of airspace a VFR flight is planned to fly in, the data element 'Cruising Level' in the flight plan item 15 is only to be completed by the letters 'VFR' and
- in the data element 'Route' in the flight plan item 15, specification of either commonly known geographical place names or ICAO Doc 7910 location indicators are allowed.

It might be different in other countries but at least in Sweden and Germany it is the same as in Denmark.
