Standard Turn Rate [What it is & How To Calculate The Correct Bank Angle When Performing a Turn].

In today's video, we are going to talk about the Standard Turn Rate.
By the end of this content, you will know what a Turn Rate is, what a standard turn rate is and why it is so important.
The rate of turn is the change of your heading expressed in degrees per second.
If you think about the implication that the Bank angle has over the distance traveled when performing a 180 degrees turn, for example, you will notice that the smaller the bank the bigger will be the distance that your aircraft will cover in order to perform the same turn.
So, an aircraft maintaining 30 degrees of bank will close a 180 degrees turn quicker than an aircraft maintaining 1 degree of bank angle.
A standard turn rate equals a change of your heading of 3 degrees per second.
It is important you respect this rate of turn when flying IFR since the Air Traffic Controller expects you to follow it and, on top of that, the IFR procedure, such as sids, stars, holding patterns, and so on are based on this standard turn rate.
When the rate of turn required for a specific IFR procedure is different compared to the Standard one this will be mentioned on the Procedure chart.

Great video love yaaa

Thanks for watching!!! Have a great day!!

Good video. If your bank angle is too steep say 35 deg. could that also interrupt the airflow into the engine and cause a compressor stall?

[@PILOTCLIMB]

I'm glad you like it!! No, a steep turn on the Boeing 737 should not cause a compressor stall.

Hi, Understood how to calculate bank angle and duration but how to you calculate when to initiate the turn?Example I'm on a 354 ° Heading inbound on a VOR Radial and need to intercept 43° heading to land. I know the tile of turning and bank angle but when do I start the turn?

[@PILOTCLIMB]

Usually you start the turn by taking the 10% of the Ground Speed.. the result should be the NM at which you should start the turn before your turning point

[@ro4526]

Hi, did you mean 1% of your GS or 10%? I'm asking as I know the shortcut formula to find the radius turn is 1% of GS. I should also have mentioned that based on this visual approach, I cannot make any turn before I reach 5NM from VOR CGS.
I'm at 140 knots following 354° inbound (CGS VOR).
From my heading 354° to join 43°inbound I need a right turn of 49°.
If I calculate my time for turning, would be speed/3° standard turn = 140knots/3=16.3 seconds.
Then my bank angle is (140/10)+7= 21°.
From these assumptions and the fact that I cannot turn before 5 NM from VOR, I cannot initiate the turn14 NM as you suggested.How do I know then when to turn?
If I use the other formula IAS ( approx to GS as close to RWY) squared / 10 , I get a radius of (140/60)2/10= 0.9 NM.
But this assumes a standard bank angle of 25-30° right?
Then in first assumption, my bank angle should be 21°. I'm confused there.
If I use a third formula, 1% of GS, I get a radius of 0.7 NM (1.4/2) correct?
Should I calculate the circumference of the circle and start turning from that circumference?
It would be great if you could help me understand this!

I didn't know it was possible to set a standard bank angle in the autopilot until I started building my own sim.
Thanks for clarifying the bank angle ratio for time it takes for a turn.

[@PILOTCLIMB]

You are more than welcome!! Let me know if you still have any questions...have a great day

[@mrkhan2983]

Why we divide it by 10 ? Can you tell me the detail

[@PILOTCLIMB]

Hey, Thanks for watching!! We have to divide by 10 because otherwise, the result won't make sense. In the video example, I calculate a standard turn rate of an aircraft that is flying at 100kt, if you don't divide the 100 by 10 your result will be 117 degrees of bank. This is a quick and easy calculation that we perform while flying. It is not extremely precise but it will make sure that you maintain a correct bank angle at all times.

[@moonshine3657]

25 degree bank rate would be 189 KIAS your already on the caution speed rate? going on the yellow arc is only for smooth air operations only.

[@PILOTCLIMB]

It depends on the Aircraft... Remember safety first, so if the bank angle is too much you can always reduce it and ask for vectors to keep you clear of terrain in case of IMC..
