Takeoff data calculation booklet Version2

Breaking news! Version 2 available!

Hello!

Some of you might remember this thread )Seeking legal advice from developers...). Even though it was taken over by a troll, I managed to get into contact with the nice Mr. Halpern, who after consulting 3rd parties allowed me to publish my "Flight1 ATR72-500 - Takeoff and Landing Data Calculation". The link to the newest version of this file will always be at the bottom of this posting!

Description:

The ATR72-500 manual is well written in most parts, but others are terribly confusing (especially the sections which deal with various V-speeds). After reading through some very helpful forum threads, I compiled all the information into a 31-page booklet which was logically
structured and took the reader through all steps needed to come up with the neccessary bug settings (without needing to browse through 100 pages, back and forward for half an hour). I also took the freedom to borrow all needed diagrams from the orientation manual.

After including the suggested improvements, I decided to start the whole thing from scratch, instead of patching up the existing document. I also finally managed to get hold of the important pages that are missing from the ATR manual! This means that the calculation should now be realistic and complete!

So: If you want to fly the ATR even more realistic and do some proper flight planning, then this is for you.

New in Version 2.0:

* Everything was completely rebuilt from scratch - over 150 working hours were necessary
* The checklist for the Flight1 Atr72-500 was completely overhauled
* 5 colorful designs of the checklist included (most checklists are not only badly written, but also in dull black and white; not this one!)
* Updated the main booklet with incomparably better information and calculations
* Corrected all errors and and bad spelling
* Included hints and tips in the main document, making a tutorial obsolete

Notes:

This is version 2.0 of the document. I did my best to make it free of errors and omissions, but some of you sure will find areas which need improvement. Your feedback is appreciated! Please write it into this thread, so we can discuss is with others!

Go to the file library at Avsim.com and search for f1atrtldv2_0.zip, or klick the following link:

Either left- or right-clicking the link should work. Save the .zip-file to a location of your choice, then extract its contents. The "TaLDC" itself is a .pdf-file, so you will need a software that can open .pdf in order to read it.

Hello!

Many thanks for this booklet.

To be honest, I do not know what to do and why. For me some explanations would be very helpful - is that possible? Easiest to understand are examples, given airports and a given situation. And I am interested why doing the single steps. Could you put all this at the end of your booklet?

 

Thank you so much for your replies!

I will note all suggestions and include them in the next version of the document. Please keep them coming! I want this to become the ultimate aid in setting up the ATR.

Great tutorial there. Thanks for all your efforts!

Hello Peter,

very good! Looking forward to the tutorial...

Well, it is one week later that promised but most probably this weekend a new version will arive.

I wrote a small tutorial for those of you who were puzzled, included the checklist into the .zip file, fixed some small errors. Right now I am working on formatting the tutorial, so it won't look like crap. Hopefully it will be done in a few days.

p.s.: Typcial case of a premature posting... I am done. You can download it now. Please keep the feedback coming! Feedback is what helped improve this thing.

That depends on your flap setting. For flaps 0 use VmLB0, for flaps 15 use VmLB15.

ATR72-500 data.    Thank you Peter for all your work on the very useful data including the calcs and tutorial.My maths is rusty (never was very good) so your info helps a lot.I am very appreciative of your efforts and no doubt the time.  Trinidad.UK.

Peter,

I'm looking forward to your new booklet. Thank you very much.

I am really glad, you people enjoy the booklet!

Version 2 is coming along nicely... I managed to get hold of the missing pages from the Operation manual and now finally am able to do the full and correct calculation. Organizing all the data is much work. It will take some weeks to finish it...

On a positive note: I managed to get hold of a friendly programmer, and he will help me create a program (similar to the wonderful "ATR Fuel Planner"), which will calculate everything after you put the neccessary data into it. That will take even longer, though...

UPDATE: I did a few more flights with the improved checklist and the new version of the takeoff/landing calculation. They work like a charm and the resulting V-Speeds are way more realistic than in the 1st version. Now I only need to make the programmer actually start working on the calculation program...

Unfortunately I am no programmer (and have no aspirations to learn it), so I am completely depending on someone who can do it (but only when he wants to)...
