Hi there! I found a significant discrepancy in SimBrief’s climb profile compared to the AFM. ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/6/e/6eeb5209d6f69af20506554e97a135e063a3facc.png) In this flight plan, the TOC is 109nm (45+10+27+27) after T/O. ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/a/a/aab65cab4d682086c5f045aba9c41177e72c9ea9.png) It’s actually impossible to achieve this climb distance according to the AFM. When flying the SWS PC-12 at a TOW of 8560 lbs, I reached FL210 just before GUBAT. Please adjust the climb calculation. Also, please check the cruise fuel flow, as it also seems incorrect. There is no cruise profile named “MCR” in the AFM; the actual profiles are MCP (Max Cruise Power), LRC (Long Range Cruise), and MEC (Max Endurance Cruise). Does “MCR” stand for Long Range Cruise? With best wishes Alexey Z. ---

@SimBrief Dear SimBrief Team, I would be happy to help you develop and refine the aircraft profile. I’m ready to run any necessary tests and can share all the documentation I have for this aircraft. Please let me know if this would be helpful — I’d appreciate your feedback. ---

Hi, > [@the10882](#): > > It’s actually impossible to achieve this climb distance according to the AFM. When flying the SWS PC-12 at a TOW of 8560 lbs, I reached FL210 just before GUBAT. Please adjust the climb calculation. Looks like you made a significant mistake in your custom airframe. You entered the following weights: ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/a/e/ae6402ad31450a66edc7dab85be945773a21c814.png) These are much too high obviously. Perhaps you entered the LBS values while the weight units were set to KG, then converted them back to LBS (which essentially doubles them). Then, in your generated flight plan, you set the units to KG instead of LBS. So your estimated takeoff weight (6,864 kg) looks reasonable at first glance, but the units error means it is actually 15,132 lbs. When a PC12 is configured to weigh almost twice as much as the real aircraft, it’s normal that the climb distance will take much longer. 😉 I regenerated your same flight using the proper weights and got a TOC around GUBAT, which took 15 minutes, 130 lbs of fuel, and 44 nm. This is very close to the real charts when you also consider the temperature deviation of ISA+10, so SimBrief’s profile looks perfectly correct. > [@the10882](#): > > Also, please check the cruise fuel flow, as it also seems incorrect. There is no cruise profile named “MCR” in the AFM; the actual profiles are MCP (Max Cruise Power), LRC (Long Range Cruise), and MEC (Max Endurance Cruise). Does “MCR” stand for Long Range Cruise? MCR is short for “Max Cruise”, but we can simply update the acronym to “MCP” too. MCR in SimBrief is the same as MCP, so if you were seeing incorrect fuel flows, this was likely also caused by the units error above. Please try correcting your airframe and generating another flight to see if the values looks better for you. We have also made a few small refinements to the PC12 profile as well now, including renaming MCR to MCP. Best regards, ---

Thanks! Now I set up my airframe as well and it’s really works perfectly. Thank you very much! ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/f/6/f62de3c8ce663ad2f929a221cb8062c4186cbe37.png) ---
