	This package contains replacement airfiles for the following aircraft : - 777-200 GE - 777-200 PW - 777-200 LR - 777-300 PW - 777-300 GE The spoilers drag has been improved to match reality more. Now the aircrafts will slow down better when using the spoilers. The original idea was by Ben ( Saratoga ) http://members.casema.nl/gsalden/CS%20777%20custom%20FDE.rar

	I hate to ask, but are these based off real world numbers and experience? -Tom

	Hate to be the bearer of bad news but only the 772_LR has been modified? The others are still set to 20! I used 55 back at V0.2 just based on trial and error. No real working knowledge of the dynamics known to me. http://captainsim.org/yabb2/YaBB.pl?num=1338411771/81#81

You can see my results under the Flight Dynamics section. I used a value of 60 for drag and it is perfect. I also looked at the Continental Flight Manual and they have very slightly higher fps descent than Qatar, but it is also based on the plain -200 and not the ER and LR models. I do not know what data Libretto put in the other airfiles as I did not look at them. Ben

	Just checked and forgot to include Ben's airfile. My apologies. This evening I will load up the correct package. I used Ben's value as a test for the other 777 versions. After having done several landings with the 777-200 GE and the 777-300 PW �with their original airfiles I came to the conclusion that they too had little spoilers drag. Then I tried Ben's value and it was way better. Therefore I used that value for all liveries. CS also used the same value for all liveries. I am at work now. Line I wrote , this evening I will upload the correct package. Just try it out. Edit : the correct package has been uploaded
