Hello

I have found the ATC Preparation Sheet and want to ask, if anyone can tell me, which kind of information must be entered in the following fields:

AVG W/C
GC%
CI (Cost Index)
Reserve (This may be the additional fuel on board)

I think, that these things are only for information ad not really important for flying, aren't they?

Hope to see some of you this evening

Oliver, you can use this data for your FMC.
AVG W/C is the average wind direction and speed of your route. You will get this information if you are using programms like Active Sky or FS Flight Keeper.
GC% is the Gravity Center. You need this valua to get your Trim data. You will get this information if you are using programms like FSPassenger or TOPCAT.
CI yes is the Cost Index. The cost index is up to you.
Reserv is the planed fuel you will have in your tanks after landing. (Reserv = Alternate+Final Reserve)

See you this evening :)
 
Flying across Europe I start to prepare for the flight here:

Knowing the route it's very easy to estimate the winds.

Hello Tomaz

thanks for the links. They are very interesting :lol:

No, but the weather forecasts thing ist really fine, the other ones are too technical for me (Especialy the Center of Grvity Thing - and the CI Document - well it ist nice to know, that it exists - but its to theoretical for me.

But the Weather Center is added to my favors and it will be a very good tool for the future.

Thanks for sharing

With my cost index in flights with Boeing/Airbus I take 100 as a value for a high speed flight and 50 as a value for an economy cruise.

Seeing as Air-Child VA doesn't seem to be too badly off in the recession I find a value of 70-80 ticks all the right boxes in my FMC setup. ;)
 
Using fspax you can sett the approximate value of cost index - of course only very approximate ;)

I have a simple rule for Ci calculating ;
depending on the number of my virtual passengers, I set the value proportional to the percentage of pax.
For example (B752, 200 pax config), number of passengers on the flight is 174, which gives respectively 87% of full occupancy, so I set my value of Ci to 87. Based on current fspax fuel prices I round this value up or down maintaining the maximum value as 90 because I do not know any airline which flies with 100 :lol: Maybe kind of government flights, paid from our taxes so it does not matter :p
Assume, in this case I have a medium-haul flight, prices are defined as normal, fuel prices are within reasonable limits, so I type 80, execute and fly with it :)
 
Hah, I employed slightly less maths but we ended up in the same ballpark. ;)

Curse my mental arithmetic!
