October 28, 201213 yr What are the respective take-off (v2) and landing speeds (vref) for the various plane models? I take it that at this point of the development all weights of the planes remain constant (no fuel consumption), Correct, we have no fuel consumption at this time. (It is supported but disables, the fuel tanks always return 100%). The issue with V speeds is that they vary with a lot of factors. It would be hard for us to compute those in real time. Our planes are typically loaded to 50% of the range from Empty Weight and Max Gross Weight. So if you have access to a chart, you can use those numbers to figure out the V-Speeds Matt
December 8, 201213 yr Author Team, I have done some research and test flights.

December 9, 201213 yr Thanks for the numbers. This should be close to what you can use in Infinite Flight. We're working on the weight and balance system so you can tweak the total weight of the planes. Just FYI, these speeds are not part of the flight model, not more than they are in real life. We set the weights, wings specifications and see how the plane flies, kind of like what happens in real ife. We don't set a "stall at 125kts with flaps 25 degrees" Matt
December 9, 201213 yr Author Team, I have also looked up the E175 to enjoy those commuter flights in the LAX area.

December 9, 201213 yr Great, thanks again We're tweaking some of the flight models for a future update, we'll try to make sure those match. -- Matt
