Hi Herve,
It's been quite a while since I've been to your web page... see quite a few changes here and there... the forum... totally shocking. LOL
I have just started toying around with AJPC, using it to compare aircraft dynamics versus documentation and ran into an unexpected thing. When using calculators that require an N1 input value, I can never dial it down low enough to do actual testing. As example... the Take off calculator. Most business jets that have FADEC tend to run N1 values around 85% or so... and you can't set the N1 value in the calculator that low. If you per chance do any updates again... could you allow for N1 values down to around 78% N1? Please?
Other than that, I find it is an excellent way to see what changing values will do to the aircraft's performance. Very well done sir. Thank you.

Hello Ed
It has been a long since I didn't go inside AJPC design and functions (by the way, it was one of the hardest piece of software I had to deal with since the very beginning). I will have a look to your suggestion. Hope that this N1 limit I set is not linked to some table or internal calculation restrictions. More precisely, so as I can focus on it, on which pages would you think it could be decreased. Feel free to use my private email (as per my home page link) if you prefer

Herve,
I understand how difficult that had to be to write... I have many thick books on aerodynamics that I use to make my brain hurt. LOL I think the only part that doesn't allow for a low enough N1 is the take off calculator. Everything else appears to be ok as far as I can tell. I'm not seeing any restrictions on other pages like I am there.

Ok Ed. Will have a look to it. Give me a few days to bury myself in the code again. Will send you a mail when the new version is available
