Fuji - Jeppview/Flitedeck is of the order of £2000 for
all of Europe, isn't it? (what Jepp call "Europe" is just the old "west of the Iron Curtain" bit and the rest is priced extra).
It's peanuts for some, silly-price for others.
I have used this product airborne and while it is super slick for a PNF pilot-passenger to monitor how badly the PF is doing
I don't know how good it is for the single pilot IFR scenario. Obviously every bit of situational awareness helps but if flying say an ILS, will you fly it on the HSI, or perhaps the FD, or by looking at the FliteDeck moving map? Doing the last option is likely to get you killed because the display scaling is far too coarse when approaching the runway.
By the way, speaking of various electronic VFR charts,
Fugawi (as in "where the fugawi?") has albums of American TPCs (tactical pilotage charts) for Europe (with adjacent bits of Asia), Africa (north of 4°N and south of 8°N), Mexico, Central America, Afghanistan+Pakistan, China (eastern and western halves), India, Nepal and Korea. These are 1:500000 aeronautical charts in BSB format - that is, loadable into FliteMap
Indeed, beyond Croatia/Italy, the obsolete ONC/TPC charts are the only option, but did you really mean running under
Jepp FliteMap? FM was discontinued by Jepp c. 2005, though it still functions. It is Flitestar but with an NMEA GPS input so you get a GPS moving map over your planned route. Can you really load ONC/TPC charts into FM? I see there are various 3rd party chart options but never found anything that runs there, other than Jepp's "VFR/GPS Raster Charts" which are £200 for Europe (padded out with the long obsolete ONC ones for Greece).
I bought some ONC charts from a U.S. online map shop and they run under Oziexplorer straight off.
