Hi, i found a table for various flap speeds based on weight, but i have found a problem.
On the chart that i have posted below is the speeds for flap maneuvre speed depending on weight. so what i done is, set up a test and loaded my 737 800W to 59t. So if you look at the chart, find my weight - 59t and use that line (58.9) is closest. So next, go along that line you will see various speeds for those flaps F0 F1 F2 F5 F10 F15 F25
Now for flaps 15 you can see the speed is 153 kts for my weight at 59t and you can see on my other picture of my PFD with my plane at flaps 15 command speed set at 154 well it should be 153, but lets say i did set it at 153 lol. Now look at my FMC for flaps 15 at 59t gives me 148kts why is there a difference in my chart and the FMC? i know the FMC is setting wind cor + 5 that gives me 153. but why hasn't the FMC giving me the correct speed that shows on my chart 153 kts for 59t?
For 59t flaps up speed on my NG is the same as the chart 203 kts. i just can't see why the difference.
