Landing Speeds

Guest

Can anyone help me find a website that has information on the landing speeds for different Aircrafts (A318, B747, etc)? Im trying to figure out the Initial Vortex Circulation of an aircraft, and i need the approach speed to do that? Can anyone HELP?!?!

~Thanks in advance

I have yet to find an accurate calculation for Vref Confused I have looked around for one but have been unsuccessful. I know one exists and I know it is very complex, the problem being that it is not done by hand, rather the FMC does it for you so its rare to find it now Rolling Eyes

Sorry Sad

Arrow http://www.b737.org.uk/vspeedcalc3.htm -- Thats the only relevant information I've found.

If you come across one, let us know Wink

I know what the formula is for finding the Initial Vortex Circulation. I have all the elements besides the Approach Speed. Which is a pain to find over the net.

For some reason, the approach speed formula is hard to find Evil or Very Mad

How longs a piece of string? You need to be more specific as landing speeds vary obviously with type but also with weight etc.

Example B752 Vref 30:
Weight 92k 134kts
weight 94k 136kts
weight 110k 149kts
