Ciao Gabriele. Thank you for the video. My comment is that Vmca is only applicable to light multi engine airplanes. For jet transport category aircraft: VR must not be less than V1, and not less than 1.05 times Vmca. When you lift off you must be over Vmca. For a transport category aircraft, V2 (attained at screen height 35ft or 15ft wet) cannot be less than both 1.10 Vmca and 1.20 Vs1 (1.13 Vs1 FBW). Also, twinjet transport category aircraft are considered to have no critical engine. Lastly, I am unaware of piston airplanes taking off with ATM or derates (less than full T/O power). I have not flown turboprop so unaware of those.
thanks captain for this informative video ...will u please consider to make a video about how boeing system is different from airbus fly by wire system ?thanks again
Hello Captain! I have question in relation to V2. Is it also affected by thrust settings and density altitude like in case of Vmca? Or factors like weight of the aircraft affects it as well? Have a good day!
Great Video! So assuming wind speed and other environmental factors are the same, since at VMCG the aircraft on ground has full controllability via control surfaces, shouldn't VMCG be very similar to VMCA if not the same since ie at 120 kts you reach VMCG so technically you can control the aircraft's Yaw on ground. Once you lift off,(in theory if speed is the same which I know practically is highly unlikely) the airflow across the control surfaces should probably be similar at the same speed so shouldn't VMCG and VMCA be very close? I know Vr is higher than V1 or close to V1 which means the aircraft could rotate, but in theory is the VMCG and VMCA very similar? This is the only part that I don't understand. Thanks!
Hey, many thanks for watching! Your question is great! The Vmca and Vmcg could be similar, however, we need to thing about these two speeds as a separated speeds that are required for different reasons. Try not to find a relationship between Vmca and Vmcg since these two speeds are tested using different parameters, for example, the Vmca allows up to 5degrees of bank angle while the Vmcg not. Let me know If I answered your question
@@PILOTCLIMB Ah I get it now, so both Vmca and Vmcg while could be similar, but have completely different meanings. And when you mention about 5 degree bank, is it done in order to reduce side slip in air due to asymmetric thrust for which needs the rudder to counteract? Like flying sideways so you can still maintain directional control but banking slightly left or right so less rudder = less drag?
Thank's a lot ! Plz I have a question they told me that with this speed, in case of engine failure we will be able to control the airplane and maintain straight flight with a bank of 5 degrees max Could you explain this point for me ?
@@PILOTCLIMB alright ! Thank's for your help ✨ Plz If you could, I ask you to make a video about toda tod Toda Tora and ASDA and thank you again All the best !
You are more than welcome! I'll take your suggestion into consideration for a future video, I have done a video about critical angle of attack.. you might find it interesting.. 👍
