Good subtopic choice, Paul. 

I think a redo of the FS IFR system would be nice. Holding patterns, crossing points at certain altitudes....the elimination of the zig zag malarkey on approach, etc.

Plenty more things will come to mind later....

A few more ideas:

Maybe a Bendix-King GPS, such as the KLN 89 or 90?

Ability to pick up radio stations through tuning the correct NDB signal (could be amusing).

Nav Aid reliability problems (especially NDBs) based on weather conditions, and maybe just a random state of the station.

Ability to speak to the ATC service rather than pressing a button (although that option should still be available).

Goodly morning all...

Yes excellent topic Paul.

I read in one of the other posts regarding MSFlight about being able to go back in time in the program.

Perhaps there could be three choices for Navigation and this is just a thought.
1...Modern Aids to Navigation that are used to-day.
2...Aid's that were used during the time period 1939 to 1965
    for example.  I would like to see the Second World War
    Nav Aids up to the invent of the VOR perhaps.
3...1909 and the First World War Years 1914 to 1918 and up
     to 1939 or the start of the Second World War.

I think this would be interesting to have a choice for the type of flying and aircraft one uses.

However this should not stop the use of a VOR, ADF or GPS being used during any time period in any aircraft if selected and that I think is very important.

Map Reading and Navigation is very important even to-day so having a very good map would be important to have in the system which should be capable of using while flying and not having to bring it up separately like FSX or FS2004 unless one is using two monitors.  Something like they do with the GPS now in FS2004 or FSX.

Just my input on an interesting topic.

Cheers...Happy Landings...Doug

(Rough copy-paste from another thread)

Emergencies - If I set my transponder to an emergency number, I would appreciate it if the ATC took notice and landed me first. If my engine is on fire I don't want to be 4th in line and have to go around!

Realistic transmissions. ATC has changed over the years a bit and some commands are now different and need updating. A slightly more realistic speaking voice would be nice too. There should be different voices for different countries, but if you're talking to some controllers they should be a little more casual. A nice 'good morning' or something like that.

More support for multiplayer ATC, or ATC mode? Allow you to run an airport when you're in that area? Again with the 'real world trains, planes and walking' suggestion, if you could just hop into the role of an ATC that would be interesting. If there was some story line/character progression then time as an ATC seems quite interesting.

Some kind of distortion and increased speed of voice would make it more realistic yet. Some people aren't veterans of flying and need the ATC to speak slower so that they can be understood, but real world pilots may get annoyed at having to listen to the ATC droning on. So if they picked up the pace for you (through an option) and added radio distortion depending on your location/distance/weather/general radio qualities then there would actually be a reason to have the 'repeat last instruction' button.

I would like a new option

"Nightmare 7-1 cleared for takeoff"
"Nightmare 7-1 requiest unrestricted"
"Nightmare 7-1 hold position..."
"Nightmare 7-1 cleared unrestriched to flight level 180"
