VNAV Top Of Descent - [What Happens If Don't Start The Descent When VNAV Wants].

In today's video, we are going to talk about the VNAV Top of Descent.
We are flying from Bologna to Ibiza and, we are approaching the Top of Descent.
You will see the sequence of the Vnav/ FMC when reaching the T/D point. The target of today's video is to show you what happens if you don't start the descent when the VNAV suggests so.
At 5 Nautical Miles from the Top of Descent, you will receive a message on the FMC saying ''RESET MCP ALT'' this means that you should set a lower MCP altitude in order to start the descent and, if you are flying using VNAV PATH the Aircraft will start the descent without any other Pilot Inputs.
If you don't start the descent the VNAV path will show you, on the navigation display, that your above the profile. The ideal Path is indicated by a magenta diamond and below that you will have the Feet deviation information.

Hey Captain thanks for all these videos you've been making. I enjoy flying the simulator as close to real as I can, and a big part of that is trying to emulate real world procedures, and not just red lining it to the FAF. Also did you know, the Zibo 737 mod better let's you download the latest METAR for any airport ICAO code - use the FMC and goto menu, AOC, and somewhere within there is something like messaging requests or weather requests, I can't recall it exactly without looking, but I use it all the time with the Zibo. Big thanks again, subbed

Hey, many thanks for watching and the comment!! Welcome on board!! Don't hesitate to comment with your questions and thoughts!!

Great presentation. Thanks

You are very welcome!

No need to set the QNH at all when descending from a Flight Level until you get to the transition level. On initial descent there is NO need to select Flight Level Change and not have VNAV path descent selected altitudes protection/restrictions by the autopilot. Just select a lower altitude on the MCP and push to select a descent speed in the speed window higher than the VNAV path speed. You will regain the path ...and can adjust the rate of closure by varing your speed intervention. Absolutely no need to deploy the speed brakes with all that unecessary vibration and annoyance to your passengers. ......just a waste of energy. ...just speed up your descent whilst you can.

Thanks for sharing your way of flying! Can I ask which airline you fly for? Thanks for watching!

Good video

Many thanks for watching and the comment!!

[@robelgebru5385]

Captain.. when does VNAV pitch mode enter VNAV speed and VNAV path during descent??…..what are the criteria for either modes to engage? Thank you captain

[@PILOTCLIMB]

Hey, thanks for watching!! The Vnav stays in Vnav path unless you push the spd int button on the MCP... The Vnav path change the logic during the Approach. I hope I answered your question

[@robelgebru5385]

@@PILOTCLIMB yes captain….thank you☺️😊

[@ccharles7008]

Want happens if we only reset MCP ALT and press ALT INVT instead of LVL CHNG? I’m this case, What is the difference between actual descent profile and LVL CHNG ?

[@PILOTCLIMB]

In order to make ALT INTV works you need VNAV, this mode is similar to LVL CHG but it will respect the altitudes constraints of the FMC.

A lot of thanks！@@PILOTCLIMB

Just a quick question regarding the VOR radials, as shown in this video you're on the R036 from the IBA VOR, the QDM is 216-217 (I can't see it very good, I should watch the Course selectors) you are on the first quadrant and flying TO the VOR (the distance that I'm now reading on the MFD is 83.5 nm) Am i correct? Thanks again for the great video explanation, I'll have to try it out myself.

[@PILOTCLIMB]

@@leonegentile6081 Hey, thanks for watching!!! Yes, you are correct!! 👍

[@sagardeepraj3344]

hy captain! how do we calculate rate of descent ... an aircraft at FL330 is required to commence descent when 65nm from a vor and to cross the vor at FL100.the mean GS during descent is 330kt?

[@PILOTCLIMB]

Hey, great question!! Check the video I made regarding this topic and let me know if you have any question: kzbin.info/www/bejne/rpDVpmCtlpiIb7M

[@daftvader4218]

Hi! Construct a new waypoint VOR-65m at FL 330 Enter the FL 100 restriction at the VOR. You are not going to get such a descent speed request from such a flight level !!?? You are still in the mach speed regime! ! You are required to lose 23000ft in 65 miles....!! Normally it takes.. 23x3=69 nm. You may well have to speed intervene! !

[@salehgarwan7028]

Hey man, kindly asking if you could make a video regarding vor holds and adf holds. Please I would really appreciate it🙏 @PILOTCLIMB
