The Vref equals 1.3*Vso, where the Vso is the stall in landing configuration.
This speed is very important since is the minimum speed of your final approach. During the descend and approach briefing you need to calculate the Vref and the Vfly for that specific approach.
Since the Vref is closed related to the Stall speed, the higher the stall speed the higher will be your Vref.
The stall speed changes with the weight and the flap configuration. The heavier the Aircraft the higher the stall speed and, the higher flap setting the lower the stall speed.
The Vfly or V approach is the Vref corrected by the wind, this speed is your target final approach speed.
In order to obtain the Vfly we add half of the headwind component to the Vref, so, once you know the headwind component you divide it by two and then you add the result to the Vref.
The V approach will give you an extra margin on top of the Vref.
So, if you take your Vso (stall speed in landing configuration) and multiply it by 1.3 you obtain the Vref and, if you add the wind correction you get the Vfly.

Excellent channel and content; how should i calculate Vfly when having a tailwind component?

@PILOTCLIMB 3 года назад

I'm glad you found the content interesting! Usually, with Tailwind you simply add 5kt on top of the vref

@ACB70 Год назад

Vfly is also commonly known as Vapp which stands for V approach . And Vapp= Vref + Wind Factors. Cheers

@PILOTCLIMB Год назад

Thanks for your comment!! That's correct, Vapp is commonly used on the Airbus.. Have a great day!

@spidey2085 2 года назад

PilotCLimb firstly great channel! my question is this: if the wind is really low, do you add a basic +5 kts always to Vref? so from any headwind from 0 - 5 kts you add 5kts to Vref and then add the headwind/2 to that?

@PILOTCLIMB 2 года назад

Many thanks for your support... When the wind is low you still add 5 KT

@slicker55 2 года назад

Thank you for another great video... I am a flight sim enthusiast trying so hard to improve my landing rates. In your Vfly example (160 knots) do you maintain and touch down at this speed or do you bleed off the speed once you're over the threshold and aim to touchdown at VREF?

@PILOTCLIMB 2 года назад

Hey, great question!! You should try to touchdown at the Vref..

@@PILOTCLIMB is the vref threshold crossing speed?

@corrosiveshurikenyt 3 года назад

Love your videos!! But I do have 1 question. So max wind correction is 20kts generally speaking so if you apply Vref +20 then, the headwind increases by lets say 10-20 kts, will there be a chance of overspeeding the flaps since your airspeed will increase? Thanks!

@PILOTCLIMB 3 года назад

Many thanks for watching!! Your question is great!! Yes, when flying in gusty winds with heavy weight (higher Vref) you might have this threat. Well done!

@corrosiveshurikenyt 3 года назад

@@PILOTCLIMB thanks!

@mrsmith8224 3 года назад

Thats why you use Vref plus 20 or 15 depending on the operator or maximum flaps plackard speed minus 5 kts ,whichever is lower

@ATRbig 3 года назад

And some sources talking about Vref= 1.23x VSr. How to understand different between V stall and V reference stall?

@PILOTCLIMB 3 года назад

Let's say that the Vsr is a safer stall stall speed. Everything being equal, the Vsr is a higher value compared to the Vso.

@norbert.kiszka 3 года назад

What about slow airplanes like a Cessna 172or even slower one? If Vref is 40 knt, then... add 20 knots? I think, this should be calculated another way on another aircraft.

@PILOTCLIMB 3 года назад

Hey, thanks for watching! The wind correction should be in accordance to the Airplane Flight Manual and Operator Operating Procedures so, it might change from one Aircraft to another and, from one operator to another. However, the general rule is to apply half of the headwind component. Have a great day!

@DSAEAyushSK 3 года назад

Hello! I had a question regarding the best rate of climb on an aircraft. I'd be grateful if you could clear my doubt. My doubts are :Why do aircraft manuals have a specified 'best rate of climb speed'? For eg:A cessna has best roc speed (Vy) of around 74kn. But why not 76 or 80? It will be faster if its more wont it? And what angle does one climb at even if it is at 74kn? At what attitude do you point the nose if you want to fly at Vy?

@PILOTCLIMB 3 года назад

Hey, great question. The problem of having an higher climb speed (as you mentioned) is that your rate of climb will be lower in order to achieve a higher speed. So, you will move forward faster but your rate of climb per minute will be lower..Let me know if I answered your question..

@DSAEAyushSK 3 года назад

@@PILOTCLIMB oh ok. Yes, that answers part of my doubts. But I dont understand at what angle or attitude to pitch the aircraft for Vy to work best? If one pitches too steep then you will stall but if its too shallow then it isnt a very high climb rate. And thank you very much!

@MrCed0802 Год назад

Hi Gabriel, Something I am confused about. I thought we stall at a certain angle of attack, no matter which speed we have. So why do we talk about a stall speed? as all what matters is an angle of attack and critical angle. Thanks a lot

@PILOTCLIMB Год назад

Hey, the problem is that when you fly slow you need to increase the angle of attack, so if you fly too slow your angle of attack will be very high and above certain values you will stall...
