Hello Ed, Thanks a lot for your courses ! It helped me on some subjects. I passed my last ATPL examination today, with Performances and flight planning.
Hi there, great videos! Thanks for sharing! I’ve noticed a couple of comments on Vs that cannot be higher than Vmca. Since I’m sitting Performance subject soon (fingers crossed) I may know where do they come from: There’s an explicit question in EASA bank where the only correct answer is: Vs < Vmca < V2min And I guess the reason is Vmca is varying according to density. It is very possible that in high density Vmca is higher than Vs that should be a fixed value. Hope that may help.. again thanks for your videos!
Hello Ed, Thanks a lot for the videos!!! I have a couple things to point out in this one though. According to the Bristol ATPL course (v.2020): Vr > or = Vs for Class B single engine aircrafts Vr > or = 1.1 Vs for Class B mutliple engines aircrafts Vr > or = (Vmu + x) for Class A aircrafts Can you also confirm that Vmu is supposed to be located AFTER Vs1? I can't seem to find any proper resource on this. Thanks again for the videos!
thanks so much for watching, thats what im going for DIRECT and to the POINT i hate all these videos with intros and bla bla, just get to the point haha
This diagram is incorrect. From Bristol online question on Performance ATPl "VS< VMCA< V2 min". Which makes all sense, how could you rotate your aircraft (lift-off) if the VR< VS (you would stall while rotating...). Can you please clarify?
same place as v2 mate. Certification requirements specify only minimum values for V2. Manufacturers and operators often choose to use the minimum value of V2 because it will get the aircraft airborne in the shortest distance.
Vmc is minimum control, there are various mc speeds. never heard of U one but it may exist. VMCG, VMCA, VMCA1, VMCA2, VMCL, VMCL1, VMCL2, these ive heard of. :) Vmcl is minimum control speed, landing configuration , one engine inop XD
PilotEd I see,You may be right.I don't have a true reference to confirm my idea,but I read somewhere that for short field t/os are done at Vmu to get the wheels out of sfc to continue to accelerate.This made me confused.So from which sources can I get official reference? And many thanks for your respond:) I have an interview very soon.All infos mixed in my mind.Thanks for help
@@PilotEd ok. captain i want to know some real information about take off condition such as angle of attack and speed to calculated the lift force at takeoff 😔😔

Thank you so much great video.... Can you please write all the V speeds definition in description of your video it will help us
Short but effective. Thanks for your help.
welcome :)
Thanks a lot for all your videos, very helpful during ATPL 🙏
Your videos a short and to the point... Amazing help thank you for taking time to male them
thanks for the kind words! more on the way soon
Very brief, very clear, very useful video! Thanks!
thanks for watching

You are a real MVP! Thank you!
Thank you very much Ed. Great explanation
cheers
Fantastic!
Hi, congrats on your video, the best and direct to the point...

thanks buddy very helpful video channel

Don't confuse rotating with lift off mate. I think your getting them mixed up. :) When I rotate my aircraft its not flying yet.
PilotEd Roger, thanks. But the point is your stall speed can never by higher than Vmca. If I reply that in Performance it's wrong...
Great videos!. Keep them coming.
thanks and wilco!
Thank you for the video. Just on question, where in the speeds sequence you apply the V2 min?
same place as v2 mate. Certification requirements specify only minimum values for V2. Manufacturers and operators often choose to use the minimum value of V2 because it will get the aircraft airborne in the shortest distance.
Thank you so much my friend, it really helped. Great video. Subscribed
thanks for watching more on the way soon
Could you please explain about hydroplanning. Thanks
sure ill put it in my todo list :)
V(LO) is max Landing gear operation speed and not lift off speed V(LOF)!!
Nice explanation, Thanks for sharing...!
your welcome thanks for watching :) more on the way
Well explained , thank you 👨✈️
your welcome more coming soon :)
Why if is hot outside thrust requirement is less? If air is hot is less dense
its to do with EGT temp
Efficient explanation. Thanks
Vs cant be higher than vr and vmca, in fact vs should be lower than vmcg
im sorry, but I think your wrong. but please elaborate remember vr is only rotation, where not flying yet.
Is there a Vmcu speed or is it possible Vmcu=Vmcl ? I can't find proper explanation about it.
Vmc is minimum control, there are various mc speeds. never heard of U one but it may exist. VMCG, VMCA, VMCA1, VMCA2, VMCL, VMCL1, VMCL2, these ive heard of. :)
Vmcl is minimum control speed, landing configuration , one engine inop XD
PilotEd I see,this is helpful enough.Thanks:)
Hi again,what's relation between Vmu and Vr?As far as I know Vr is greater than Vmu,isn't it?
other way round i think Vr comes before Vmu, a little counter intuative i know ;) but you start the roatation and then the unstick speed occurs
PilotEd I see,You may be right.I don't have a true reference to confirm my idea,but I read somewhere that for short field t/os are done at Vmu to get the wheels out of sfc to continue to accelerate.This made me confused.So from which sources can I get official reference? And many thanks for your respond:) I have an interview very soon.All infos mixed in my mind.Thanks for help
U missed f after vlo because should be vlof, and vlo, is the max speed at which landing gear can stay extended.
well spotted thanks! :)
Small correction there. Vlo is the max landing gear operating speed (when the gear is in transit). Vle is the max speed when it is extended.
yep corrected in the description thanks :) just a typo
PilotEd no I'm talking about the guy who commented. He was slightly mistaken
Isnt Vmca less than V2? why is it less than Vr....the aircraft is still not in the air....
have another watch at the video and see if it makes sense :)
hi Captain , can i get any social media to Connect with you, i have equations
haha not on social media sorry, :)
@@PilotEd
ok.
captain i want to know some real information about take off condition such as angle of attack and speed to calculated the lift force at takeoff 😔😔
