    Posted: April-10-2016 at 9:49am
Hi,
for the ATR 72-500 take off the tutorial manual (page 31) says to advance both PLs to TO NOTCH and specifies "right mouse button click on PLs on engine control panel ". My question is WHERE IS THE POWER NOTCH, or how can I identify it? If I right-click the power levers move all the way up. If on the contrary I click left mouse button, I can guide the PLs, but up to which point ?
Thanks

Just right click between the throttle handles when starting your take off roll and they are set into the notch. Thereafter only the mode switch is required until descent.

If it 'aint broke dont fix it.

Thanks, so the Notch is actually the upper end of the PL slide
-----------------------------
Now another question, please.
The Take off TQ is computed according to PWR MGT setting, and a yellow triangle is posted on the TQ meter.
During TO the tutorial says "check that actual TQ matches take off TQ (manual bug) and adjust moving PL if required".
Now, what's the function and need of the manual bug, if the required TQ is automatically computed and posted with the yellow triangle ?
Thanks again
C.

1. yes that's where it sets to.

2. Sorry Chestnut but this question is a little to deep for me. I just wait for the rotate call out and up we go. I then climb on auto pilot using the speed setting facility.

The computed torque setting for takeoff (solid yellow bug) is the "reserve" torque T/O setting. This is the maximum that can be used and will be provided automatically in the event of engine failure on take off/climb out.

A normal takeoff will use a lower Torque setting (manual bug), computed from the tables in the manual. This torque value is manually bugged by the crew, and is the one referred to in your quote above.

The manualy computed TQ setting is a bit like a derated T/O thrust in a jet turbine.

Thanks, that clarifies the situation. I'll now try yo learn how to compute torque.

Sorry to not be able to help but I wish you every success. Enjoy the plane, it was just about the first major attempt at producing a realistic flight model and a very good attempt it was.

David ....
thanks for having been the first to answer. Now we both know something more about torque, even if I still have to discover how to compute the valude to bug manually.Smile

Pschlute ....
thanks again for your answer. I have gone through the manual but I'm afraid I did not find any TQ computation table. Would you please assist once more telling me where I could find them ?

page 304 of the manual has the chart for T/O torque

Thanks,
found that page. Actually I was looking into the simulator manual which I printed after installing the ATR.

I have the printed Aircraft Flight Manual with all the tables etc, but I do not find anymore the digital (possibly PDF) version in the installed software.... where should it be ?
Thanks

The manual can be accessed either from your windows start button... Flight1/ATR/

or directly from your sim/Flight1 software folder.

Sorry for being still here, but after looking into all the folders where there is Flight1 ATR material I only find the Orientation Manual F1ATR_COM, but not the Aicraft Manual. Maybe if you would let me have the file name I can search and find out where it finally ended on my HD.
Thanks, have a nice week-end

The Orientation manual is the one I am referring to. The only other manuals installed are the Config manager instructions, and T-O-M instructions.

It is 481 pages long and contains everything you need to know to operate the aircraft, including the tutorial flight and the tables needed to calculate T/O torque.
