6th!! I wonder if Sibwings will also get their Bird dog out this coming week as well. :jump:
 
My only question has to do with the hydrodyanmics? Seaplanes have to transition to "on the step" which is a fairly critical operation at heavy weights. FS does not naturally model this and the dramatic reduction in water drag. To get on the step it is necessary to hold the stick/yoke well back and ramp up into a somewhat nose high attitude, shifting the drag center aft and then rocking down (letting the nose fall) into the planing attitude which is maintained till flying speed is achieved. As with a number of areas in FS, the sim engine is not designed to cover all circuimstances. It would take some contact point sleight of hand to achieve this but it might be possible to model. Were you guys able to achieve this to some degree?

It is a great looking plane and I am glad to see that you have gone the way you have with it!

Hi Tom

I´m Finn Jacobsen the XML Gauge developer of the Aerosoft Catalina X.

We have not done anything to make the aircraft come "on the step" more realistic, but we have made some custom coding of the water drag to make behaviour on the water more realistic.

Water in FSX ghas become less draggy than it was in FS2004 (remember the "sticky" water !).
But FSX doesn´t sense wether the aircraft is o the step or not. This means that once Your are too slow to be on the step, the aircraft still acts like it is. This means that at slow speed water drag is too low, making stopping the aircraft in the water difficult.

On the Catalina, we have added code to gradually add more drag as the aircraft slows down in the water, effectivly bringing it to a stop.

This also works when accelerating on the water. At first the water is quite draggy, but as Your groundspeed starts to build up, water drag becomes less, like if You come on the step.
I´m sure that it isn´t perfect, but still way better than the default water behaviour.

We have also added invisible watter ruders, that are extended and retracted without any user input.
This has been done to make it easier to control the Catalina i the water. These water rudders will extend when groundspeed gets below appr. 17 kts and will be retracted above.

We have also added code to add more drag from cowlflaps and floats.

Best regards
Finn Jacobsen
 
Thanks Finn:

A good explanation. I have now flown the plane quite a bit and might submit a few comments to you personally as I am trying to be helpful and not critical. It is very apparent that the drag coefficent of the water has been changed from FS9! This also appears to be the case as well with snow and other land surfaces, with some good and bad results.
