Manual PPC calculation is still an ATM task during contact phase in the 47 course. I find it beneficial, especially because you learn more about HOW you’re limited (e.g. PTIT, XMSN, NG when FAT is super low). Our IPs and company SP also go into great detail about the implications through scenario-based training. Good stuff! Thanks for posting this video! Performance planning is a subject I’m fascinated with
Its always good to manually compute PPC to determine whether the FMS computations are also accurate. it also helps big time with the planning prior to the mission.
That’s a great question. From what I’ve read the continuous torque value is concerned with TGT so that is the torque you can pull and be under the 30 minute limit for TGT. The torque time limits would still apply in this case because we know the chapter 5 limit says we can only exceed 100% torque for 10 seconds above 80 kts. However, if you are below 80 kts you do not have a time limit for this torque because you are allowed to pull up to 120% and not be limited to time at 80 kts or below.

Hell yeah man! I see a huge benefit in manual calculations. I’m glad you liked the video. Thanks bro!
Great job..PPC helps us frying the helicopters with our minds not our hands
Thanks a lot man, currently in flight school and this really helped!
Great to hear! Good luck.

Very true. The biggest issue I see when calculations are off is inaccurate GWT or inaccurate wx data.
Thanks for your videos . This one was especially helpful!
No problem. I’m glad you found it helpful.
Great lesson, would you be able to explain asterisk on the predicted hover line (*140*)?
In short, it’s telling you that you don’t have single engine hover capability.
For this example with continuous torque being over 100%, are we still restricted to -10 continuous torque limits of 0-100%
