ATR Systems - FMS part 1.1

This is Part 1 of a series of videos about the Flight Management System (FMS) in ATR 600 series aircraft. It shows the initial setup of the FMS and how a flight plan is made in preparation for flight.
Revision: The procedure for initialization of the FMS was changed with the introduction of STD 2.1.

Love how the annunciator lights go dim once you hit the starter, I have never seen that in any other plane

[@FlywithMagnar]

The annunciator lights might go to dim when you press the engine start button. This is caused by a drop in the voltage from the GPU. As soon as the voltage is normal, the annunciator lights will become bright again. Important avionics are protected from this drop in voltage, as they are powered by the emergency battery during engine start.

[@Mike25654]

@@FlywithMagnar Very interesting, maybe this is due to the fact the ATR has only one Main Battery while all comparable aircraft (Dash-8, E-Jet's, etc.) have two batteries plus an emergency battery? Therefore the voltage in the electrical system drops (apart from the Systems powered by the EMER BATT) while in other aircraft the essential DC busses would be powered by the battery not used for engine start at stable voltage.

[@aviationtalkandtutorials2456]

Great Vide Captain, is the FCOM for the ATR available online?

[@vfx7t]

💪💪💪

[@jameschen9099]

Hi Captain, pretty unnerving to returning to the main menu leaving the boxes empty in the P.Pos page ! Do you confirm the lat long on P.Pos page with your plate ? After confirming its accuracy can you pick that line and copy on to the scratch pad and then press the line key you want to copy to ? thanks for the video.

[@FlywithMagnar]

A lot has happened since the 600 was introduced. As, the FCOM states, it's better to leave the boxes empty. Yes, we confirm out position with the airport chart or signs at the parking stand.

[@eddizorzini8369]

First of all thanks for the excellent tutorials and explained in excellent and very understandable English. Then 2 questions if I may: Today I effected a planned flight using the AUTO SPD SEL speed selector (target speed indicator in the PFD in magenta) and I saw that the right speeds are automatically set for the various phases of the flight (e.g. 170 knots in climb, 240 in cruise, Vapp in final etc). The question is where are these speeds set (except the Vapp of course) ? Another question: once the flight plan has been entered, how do I change the speed in the MCDU, how can I change the speeds indicated in the SPD column ? Thank you Ciao

[@FlywithMagnar]

The speeds are defined by the FMS. Once the FMS knows the weight of the aircraft, it calculates the speeds for takeoff and landing. (Fuel consumption is accounted for.) The speeds are also adjusted for icing conditions when anti-ice is selected. The cruise speed depends on the alitude and atmospherinc conditions. The FMS also takes into account any speed restrictions published in the SID and STAR. To only way to change the target speed, is the select manual speed. We do this when ATC instructs us to fly at a certain speed, to mention one example.

[@eddizorzini8369]

Thank you Captain for your quick answer.

[@supergazell7]

Hello captain, I have a question. At minute 16:48 you enter a MAC data with a value in 26.5%, I am a simulation enthusiast in MSFS2020, I use SimBrief to create a flight plan. This value is generated by SimBrief when the ATR is selected? or how can I get it?

[@FlywithMagnar]

The MAC data is from the loadsheet. It varies with the loading of the aircraft. I do not use SimBrief, and therefore, I do not know how it works with this application.

[@gary4188]

Hi Captain, thank you for all the information you give us on the ATR. As a sim pilot i have been enjoying the ATR, but the one thing ive noticed with sim version is it seams to take alot of runaway to get up to speed, im forever having tail strikes on rotation even at Gatwick. I can't see how this would be the case in the real thing. Would love your view on this. Many thanks Gary.

[@bbgun061]

I can't comment on the accuracy of the sim. However, a tail strike is caused by either rotating at too slow a speed, (below Vr) or rotating too quickly. It should take about 5 seconds to bring the nose up to 10 degrees.

[@FlywithMagnar]

Hi Gary. Good news: The developers are working on the issue. The next update will have a better acceleration. This has taken longer time than anticipated. The reason is that the base model (FS 2000) has some limitations for the developers. This why Microsoft will launch FS 2024.

[@danielmartello9621]

Hi Captain, your videos were really helpful for my initial training. One question. Why is V2+5 selected in the SPD Sel before take off? Thanks!

[@FlywithMagnar]

Less drag and therefore better rate of climb. For the same reason do many airliners use V2+10 or 15. V2 alone is only usd when there's an obstacle close to the runway end.

[@abuibrahim2153]

Hello Capt Magnar, do you know or if there is any application that is a computer based trainer for the FMS 200. Also what’s the best way or source to learn the FMS 200. I have looked for applications like the boing or airbus has to help with practicing. Or is there any similar app from airbus that someone can use to practice. Thanks.

How do you store a list of flight plans?

[@hariomch]

Hello Capt. Hope you are fine and healthy. What if Xtalk fails in flight. I had the same once in flight. LHS was fine. RHS was way off. Hence we completed the flight normally from LHS. Thanks and regards

[@FlywithMagnar]

Cross-talk fault does not affect the performance of both FMSs. They will switch from dual mode to independent mode. Each FMS are still functional and can be controlled with its respective MCDU. But you must remember to enter the same information into both of them.

[@corinaolarescu590]

Hello Magnar! How many DME units does an ATR 72-600 has? I am a little bit confused about the chanels/dme units difference....

[@FlywithMagnar]

Two, one for each VOR/ILS recevier.

[@eddizorzini8369]

One last information: would it be possible to anticipate or delay the TOD point established by the Flight Management System ? Thank you

[@FlywithMagnar]

Yes, you can change the descent gradient.

[@bbgun061]

I'm an ATR pilot and I have a question about the POS INIT page. After completing a flight and while setting up for the next one, I check this page. However, now the INIT POS does not match the GPS position. (Or the LAST POS) It is often many degrees different, so it is not a small error. Can you please explain why this happens? I always select GPS POS for this reason, and because my airline has not updated its procedures. Thank you!

[@FlywithMagnar]

Hi, according to the latest revision of the FCTM, we do not check the POS INIT, NAV DATA and UNITS pages. Not even during initial setup. The reason is that the FMS uses many sensors (GPS, DME, VOR, etc) to compute your position. When you select GPS POS as your current position, you exclude the other sensors. That means your position is less accurate than it should have been. If there's any problem with your position, the FMS will give you a message.

[@bbgun061]

@@FlywithMagnar Thanks. I understand, but my airline has not updated its procedures to match the latest revisions. My question was about why the position shown is so far away from our actual position. In one case it was at a point 415 NM away...

[@braininavatnow9197]

Is it possible to go out on a sunday afternoon VFR pleasure flight with the FMS turned off?

[@FlywithMagnar]

I would keep the FMS on because it computes speeds for takeoff and landing. This requires you to insert the weight of the aircraft and weather information into the FMS. However, it is not necessary to insert a flight plan into the FMS when you fly VFR.

Hello Sir I know you are a real pilot/certified flight instructor for the ATR but I was wondering if you could make a video about what is correctly/incorrectly modeled in the ATR 72 -600 that is offered in the Microsoft Flight Simulator and what needs addressing. Thank you in advance.

[@FlywithMagnar]

Hi, such a video will require a new edition every time an update is released. And they will be frequent in the first months. Most errors are cosmetic, such wrong color in an indication. The FMS is incredibly complex, so there are still some issues to be solved. I will release a video soon, showing what is working.

Magnar I am not a pilot. You may delete this comment if you feel it detracts from your video or if it might confuse someone. I thought that most commercial aircraft have load sensors to determine the actual weigh on wheels. Does the ATR 72 lack this feature or am I misunderstanding about larger aircraft. Thank you.

[@FlywithMagnar]

Hi, thank you for your question. There are no stupid questions; only stupid answers. To my knowledge, none of the today's transport aircraft have load sensors. Honeywell developed such a system in the 1960s, and it was offered for Boeing 707, Lockheed L.1011 and Boeing 747 freighters. However, the reliability of the load sensors was poor, and it was considered to be waste of money. If you cannot trust a system, you better not using it.

[@paulloveless4122]

@@FlywithMagnar I see. And because the weight is such a critical number it must be delivered reliably. Thank you sir!
