Great quality content and extremely helpful
Glad to hear it!
Beautiful... made it very easy to grasp...
Glad you like the video.
Can you give a quick intro of yourself?
Are you a pilot?
Type?
thanks a lot for such great video Sir.....👍👍
thank you for watching
What a gem of a channel, I am so glad I found you, you deserve way more subs man.
Thank you for the compliment.
Could you give a quick bio of yourself. Nothing too detailed.
Just if you're an airman or enthusiasts etc. What you want to see education or GoPro videos.
Thank you again
@@flightlevelview2115 of course, means a lot that you care, currently I am an “enthusiast” I guess you could say, but I am working towards my PPL and have flown planes in real life (mainly a Cessna Grand Caravan 208) since I work at a dropzone (skydiving center) packing parachutes and editing videos. So while I don’t have my license, becoming a pilot is a dream of mine and a strong ambition. Honestly both content sounds absolutely amazing for different reason but if I had to chose one, it would GoPro, because it’s more beneficial to see what’s going on inside the cockpit and observe what your doing, especially if you talk through your process. So I guess it’s kinda mixing the two isn’t it xD. Your educational content is great though and definitely important as well. Keep up the good work!
(Just read the part where you said not detailed, whoops)
@@apogee9973 I so want to get my USPA class A license as a bucket list.
Feel free to write any topic you want in the comments section. Ill try to make the video ASAP
@@flightlevelview2115 Awesome, thank you man! I will bare that in mind.
Really amazing video. Please do keep making them whenever time allows. Shared with my friends and subscribed, would love to do what I can to help the channel..
PS : You also motivated me to work on my drawing skills xD
Thanks for watching. Could you give a quick intro of yourself, nothing too detailed. Just are you a pilot or dispatcher or up coming pilot etc.
My drawings aren’t that great, I’m trying to up my youtube game.
Thank you for watching
Also are your friends pilots or dispatchers or up comers.
@@flightlevelview2115 I’m a pilot about to start an airline career, just got a TR on A320. Also my friends are pilots at various stages of their training and careers.
@@kinshuk-311 thats good to hear. You're on a great jet. 👍
Thank you for watching and commenting.
You can ask anything aviation anytime.
Excellent explanation! Greetings from 747-4 FO
Thanks for watching. I won’t ask for anymore of your details.
Only, do you have any other questions or suggestions?
Thank you for the explanation! You did a great job with that drawing app too.
SmartChannel thank you
Nice job. Thank you.
Thank you for commenting
Thanks for this 🙌🏻
CASA lists the concept of derating as part of our syllabus knowledge required for an ATPL (A), but the aircraft used for the performance exam is the 727, with no graphs or procedures provided for derating take-offs 🥴🤣🤦🏻♂️🤷🏼♀️. As such, the main theory provider for the ATPL syllabus here in Aus does not cover the concept of derating at all 😂
Thanks for watching and commenting. If you want to know something else listen to off some ideas.
Ill see if i can make the next video.
Hey, man. Thanks.
Nuit Sindhuvanich thanks for watching. If you want to see something else plz write it down in the comment sections below.
Thanks for the video. Good explenation. on a technical note - try not banging on stuff while recording. It gets distracting.
Thanks Kuba. I'll make sure not to bang on stuff in the future.
Ok explanation
Thanks you for commenting
Thank you for the great video, helps me a lot as someone new doing a Boeing type rating. Just a quick question: it states in the FCTM for the 737 that when using a combination of derate and ATM that we must always select the derate first and then the assumed temperature, is there any specific reason for this?
First of all thank you for watching and commenting…
I think i understand what youre asking.
If you wish to use both DERATE and ATM. You need to first select the derate (TO 1 TO2) because if you don’t
The FMS would by default be set to D-TO (“FULL RATE”)
If you do not select TO 1 or TO 2 first before you insert the ATM temperature, you will just be using solely the ASSUME TEMP METHOD. (D-TO)
In a way, pilots are ALWAYS using a mixture of (De/Rating and Assumed Temperature Method.)
Example.
D-TO 53C FULL RATE with ATM. (This is what pilots consider using only ATM with no derate)
D-TO1 53C Derate 10% with ATM
D-TO2 53C DERATE 20% with ATM
I hope this helps
I need to make a correction to my video.
Once you are above the V1 speed VMC is not a factor. V1 speed is greater than VMCG.
The concept still holds true. The PIC shouldn't just shove the Thrust levers beyond the Derate thrust limit, unless the PIC determines that more thrust is needed. Example: wind shear scenario.
This video was was far by the best I’ve seen!
Would love to see more content on anything you prefer but Assumed thrust method please.
Keep up the good work
Really inspiring

@@Zfx13 if you have any specific requests please writing them in the comments. Best regards
Thanks for the video!
Can you please explain how does a lower Vmcg allows higher takeoff weight?
Thank you very much.
Thanks for commenting. I will get back to you once im on the ground.
Are you a pilot by any chance?
You want an explanation or are asking for a video?
@@flightlevelview2115 it would be very kind of you to make a video. But if it's going to take a lot of your time, I would appreciate a reply with the explanation of the topic.
I appreciate your effort!
@@mi-789 are you a pilot by any chance? Not too much detail. If you are, just wondering if a student or commercial or airline etc. or just an enthusiast.
@@mi-789 I’m asking because i want to know who my viewers are and what they want to see. Educational video or just Go Pro videos.
Can you give a better explanation on VMCG is a go or stop speed? And why does GE use N1 and Pratt use EPR?
"Vmcg is a go or stop speed?" Not sure what you're asking.
Are you asking me to explain what VMCG is?
And what accelerate stop and go is?
I am not sure why engine manufacturers choose to use N1 or EPR over the other
I meant to say is VMCG a go speed to maintain directional control; while continuing the takeoff, whereas if you are going to stop VMCG is no factor? I'm new to some of these terms thanks for your videos.
@Fr Li Vmcg minimum control speed on the ground. Is the speed at which the rudder can counter the asymmetric thrust developed during a engine fail scenario.
Vertical tails are like wings. More speed more effectiveness, less speed less effectiveness. So, more asymmetric thrust means harder to keep control with rudder and less asymmetric thrust means easier to control with rudder.
Not directly related to accelerate Go or accelerate stop.
The decision to Go or Stop is predicted on more factors than just Vmcg.
Decision speed V1 involves being able stop safely on the runway and be able to takeoff whilst maintaining a certain climb gradient above terrain or obstacles. Winds, wet rwy/ rwy contamination, etc…
Also V1 takes into account the aircraft ability to completely stop. If you’re too fast the brakes might not be able to stop you on the runway. Vmbe. Max brake energy
