Excellent !!! I wish this were available when I was doing my initial ATR type rating.
Really love such videos where you get to dissect a checklist and really understand why it calls for certain actions to be executed. Would be great and appreciated if you could do more like this. Cheers skipper.
Fantastic video. I've been flying the ATR for 4 years and am still learning. The way you explain these systems is very easy to follow and understand. Keep up the good work!
Hello Captain, I am an ATR Pilot as well and your videos are very much useful in better understanding of systems. Can you please make a video on
OEB 56 Issue 1: POTENTIAL TEMPORARY LOSS OF ALL COCKPIT DISPLAY SYSTEMS
and its effect during DUAL DC GEN FAULT.
Thanks, Rohit.
Great overview of the problem in the different ATR versions, thanks
Thank you for this great video, Captain. I have a PPC renewal coming up and this is helping me refresh my memory. Cheers!
Nice... Really nice Captain... Always a pleasure to see you ! We had during an OPC, on a SID, a DC Gen 2 faut followed by an engine 1 parameters overheat, so we needed to shut it off... So there, we were... After the assemment, we also had hydraulic green pump overheated... Was though but good... We survived 😅
Very clear and informative video. I would enjoy and appreciate any ATR failure video as well as deeper background info on systems already covered as an introduction. Maybe by using QRH procedures -like in this video- as a guideline to explain the direct and also the indirect consequences of a (combination of) failures? Thank you for all the work you have put in already 🙂.
As usual, another excellent video...thanks a lot Magnar!!! I always learn something new and I find it very useful for review the systems and procedures!!! Please, keep making more videos about emergency and abnormal procedures!!
Great work!!
As a PPL pilot, looking forward to two "study level" ATRs in Flightsim, I really enjoy your channel. I hope I am prepared to fly the ATR when it is released next year. Thanks for your efford, making these videoes. So interesting.
Our company fly both the 46 and 76, and we always turn on the TRU after both engines have been started, and leave it on the whole flight until after landing checklist.
Great video Captain. Please, continue with the excellent work, helps a lot! Thank you for for all those excellent videos.
Thank you so much Captin. For all presentation very useful If u pls and have time. I need to show us the drive down above high train and low train and how airplane work and the right procedure
Great Video Captain. It'll be very great if you share more videos regarding Abnormal Procedures which occurs during daily flights and as a Captain, what will be my procedures and actions. Regards.
I learned and revised alot from you, thanks capt!
As always Captain, great video and great knowledge transfer to all us Pilots, you are a great instructor. A BIG Pura Vida from Costa Rica.
Thank you!
Love your videos sir! Please continue making them 😊
Very interesting. Thank you.
Thank you Sir. This has been a lot informative.
Thank you Capt.
Excellent video….
What an awesome tutorial. Thanks Captain, can you explain approach plates in an upcoming upload. Thanks Captain. - Surry Virginia
Thank you! I will put your request iin my to-do-list.
Funny that they tell us to shut off the green hydraulic system to reduce the load on the ACW generator...
When we've all been flying for two years with the hydraulics and the TRU on all the time...
A protection trip initiated by the associated GCU. If it is caused by a
generator underspeed, reset will be automatic. For the other cases,
a manual reset has to be performed (but can result in a loss of the
opposite generator) .
In regard to the above statement excerpt from FCOM would you recommend reset in case of s single DC GEN FAULT
As long as i see only one amber light, I would try a reset. But only once. The risk of losing the opposite generator during a reset is very small. Each generator has its own GCU. According to the QRH "At flight crew discretion, one RESET of a failed system associated to an amber caution may be performed by selecting the related pb (push-button) OFF (for 3 s) then ON except for systems listed below..."
Thank you for the prompt reply
Very interesting! Please make more videos!
Will do!
He has made numerous detailed videos about each major ATR system.
Made that comment before I watched to the end. Yes! More contingency procedures!
Excellent video thank you. I hope the atr coming to flight simulator is detailed enough to practice these procedures!!
I hope so too!
The ATR is coming to MSFS?
Yes, it is the making.
@@jimlthor it's being made with milviz and asobo. Will be the glass cockpit version
So just did some reading and apparently it will be study level and they have more than 10 atr pilots testing it now. Should be released soon.
Hello, do you have more information about the new procedure regarding the TRU? Do you know if it affects other systems while putting it on?
The procedure was implemented after some incidents where the crew lost all DUs and IESI in flight. Here is one: avherald.com/h?article=4da477c1&opt=0
Engaging the TRU after engine start prevents this from happening. ATR is working with a more permanent solution. No, other systems are not affected.
Exellent video Cpt thx and Could you tell me if a turboprop like ATR is subject to ICAO noise restrictions in the vicinity of airports exactly as well as jet planes ? if so, what is the anti-noise procedure on departure? I can't find it anywhere ..
There's no noise abatement procedures for ATR aircraft. They comply with current noise requirements.
Hello magnar, I have a question, please help me. Why some push buttons like BTC, ACW, DC SVCE, in the overhead panel have a yellow rectangle around it. I apreciate your help.
The yellow circle around some pushbuttons is to help the pilot to identify them in case of electric smoke.
Great video I just had a question about the ATR : Why during the start-up the propeller looks like its in full feather ? Sorry if the question has not much to do with that video I was just wondering. Keep doing great videos much appreciate it.
Yes, the propeller is in feathered during engine start and shut down. This is normal for engines with free turbines, like the PW120 and PT6.
Is there are chance to recover one generator by selecting DC BTC isolation and then trying to reset generators?
No. The reset is done in an attemt to re-engage the GCU - Generator Control Unit.
Thanks for an interesting video. I have not dived so deep into this checklist for the AT76 so I was not aware of this 3 yes/no-items (stall warning, speed/alt or none…). But exactly what do they mean with speed/alt? I guess it means that if we are low on speed and below 1000’ agl we cannot engage the AP until we have speed 160+ and 1000’ agl? But what about approach later? Must the AP be disconnected when we are descending through 1000’ agl or when we start to configure for landing with speed below 160? Not super clear in the procedure I think.
"If IAS
@@FlywithMagnar Thanks Magnar, yeh it does say Prohibited but why not during the item “For approach” have the followwing item?: When speed below 160kt and/or below 1000’: AP disconnect (if engaged). But I guess we have to “think our selves” ;) Like on eng 1+2 flameout leading to forced landing. On FORCED LANDING checklist it says before the item “if no engines operates”: LDG GEAR….down as req. In the case where we dont have any eng running, we will need to use gravity extension which the checklist does not take into consideration really. It helps us with flaps via the AUX HYD P/B only in the case of no engines operating. Easy enough, but during that stress with no engines running it would be nice with all the help and hints one could get from a checklist :) Thanks again for your videos Magnar
Why is there a Flight level cruise limitation of FL200 if ISA+25??
The higher you fly, the less air there is to cool the remaining generator, which has double load.
Hey cap have you used the atr albatross software it's really cool to simulate failures
Hello Ahmed. Does thr Albatros software available for anyone or just from ATO? Thanks
Kevin
@@kevingire793 they provide it to MRO as far as I know. But the subscription is quite expensive
@@ahmednasrulla4766 thanks 🙏🏽
This might be a stupid question but where does APU and RAT comes in?
ATR aircraft do not have APU or RAT. Instead of APU, the propeller on engine #2 can be hold in position by a propeller brake. This allows for the engine to supply the aircraft with electrical power and air conditioning. RAT is necessary for aircraft with hydraulically operated flight controls. ATR has manually operated flight controls and doesn't need RAT.
