To illustrate the setting, please find below a) the Skydemon chart, b) the VFR approach chart, c) the IFR obstacle chart, d) a topographic map e) Jeppesen mobile flight deck of Klagenfurt and the immediate region north of the airport.

2. VFR approach is by sectors (see b)) with a maximum altitude of 3500ft

3. two small holdings at 3000ft (see b))

4. directly north of the aerodrome are hills of 1000ft agl (see c), d), e))

Skydemon depicts only the VRP (1). The sectors (2) are missing, max. sector altitude is not shown, the holdings (3) and their altitude are not shown, the terrain (4) is not displayed. But it is the terrain that forces an atypical close and atypical high downwind for an international airport.

All this gives the false impression using Skydemon of a free approach sector north while there are hills 1000ft agl. The mental picture provided by the Jeppesen chart is fundamentally different: in fact, the north sector is anything but free of obstacles.

Hello,

I'm not trying to take side in this little discussion but I'm interested as I'm not used to flying in mountainous areas and try to gain all means to get a better image of the terrain I'm flying to.

One tool that I use in SD is the ability to color terrain, I usually set the projected flying height as the reference altitude it then shows in red all terrain only 500ft below me.

For flying into an airfield like LOWK one could set the reference as 3000ft which will show in red all terrain 1000ft AAL, in orange all terrain 500ft AAL and yellow all terrain below 500ft AAL. (see picture)

It is great as a planning tool, maybe less for flying as it clutters the screen a bit.

I know it does not really answer your request but to me seems at least an interesting workaround.
