Hi Brad

Nice to meet you ...Yes this works for me too....But for some reason the last 2 flights with FSP have ended in tail strikes on takeoff and
crashes on landing which in 10yrs of simming I haven’t done that often...What I mean to say is this....

If I do this:-
1. Program the FMC when the planes is NOT loaded with pax/fuel etc
2. Then automatically populate the V Speeds as you say Brad.

Then I do this:-

1. Starup FSP
2. Load up the plane with Pax/fuel/cargo etc
3. It then shows me the load sheet and asks me to input V Speeds (I know this is optional)
4. I cannot input the same V speeds I have already in my FMC because now the planes is fully laden so they will be incorrect.

I am very frequently getting tail strikes and it has come to the point that when I take off I have to trim the Ailerons/elevators using my trim
switch on my CH Products Yoke just so I can actually leave the ground....I nearly go off the end of the runway!
I am 100% sure this is to do with the incorrect Centre of gravity.

Question:-

1. How do I actually load up FSP with any aircraft correctly so my loading and speeds are correct?

Surely someone out there has the same PMDG Aircraft and uses FSP.
But honestly it is no worry if I have to leave the V Speeds Blank and just let the PMDG Guy call em out.

This is still the BEST EVER add-on I have bought in some time.

Kind regards to you Brad and thanks to Dan for this great product...many thanks to all you guys in this great forum that is without a doubt
one of the nicest forums I visit.

Cheers Guys Paul
