As much as folks appear to like this content, the content is incorrect. Drift does not equal Wind Correction, usually. Drift angle for this case is 9 degrees left so it's 1 degree off the wind correction angle which is what is calculated in this video. The reason people are taught to mark the wind speed down, instead of up, for drift is because the drift triangle is different from the wind correction triangle. For drift, set index=wind angle, set grommet=TAS, mark windspeed down from grommet, rotate and set index=course; read both groundspeed and drift angle from mark (111kts and -9 degrees in this example).

@atplmadeeasy2495 3 месяца назад

Hi, thanks for the feedback. I am not entirely sure what you are referring to, however the answers in the example are correct. Having used this method myself in ATPL exams it has been designed to follow the layout a student can expect during either ATPL or PPL exams. Please feel free to use the official e6B calculator online or another reputable source using the example and you will reach the answers I have provided if you do not agree. The method I have demonstrated is a quicker and easier way than the marking down method, this is aimed to speed up students in exam conditions.

@@atplmadeeasy2495 I've tried three times to reply including a web reference but looks like youtube doesn't allow this? WCA=negative DA if the aircraft heading = WCA. If aircraft heading is not WCA, then drift angle is almost always different. I'd point you to my writeup on this but, as I said, youtube seems to not allow it.

How can you determine wind direction and speed when you are airborne? (let's not consider ATIS or electronic help). And if you are in need of this analog computer while flying solo: how you handle it while also handling the yoke? (consider no autopilot). I always though you need a second person for this.

@Uncommon_Sense01 2 года назад

Do you know how to use this to calculate ETAS? Thanks

@johnhebert3855 2 года назад

When plotting the wind speed, what determines whether you go UP or DOWN from the grommet?

@flybobbie1449 Год назад

Two solutions need wind above, third type (rarely used) needs wind drawing down.

Would be clearer if you drew on the wind arrow. Nice to see easy methods, not some of the wacky one's and wrong answers seen over the years.

Also use pencil, pen will stain.

To determine your heading, drift angle, and ground speed, you can use the wind triangle method. Here are the steps and calculations: Track (T): 290 degrees True Airspeed (TAS): 100 knots Wind: 090 degrees at 30 knots Step 1: Calculate the Wind Correction Angle (WCA) The wind correction angle is the angle between the track and the heading necessary to counteract the wind effect. Using Trigonometry: WCA = arcsin ( W * sin(θ) / TAS ) Where: W = wind speed = 30 knots θ = difference between wind direction and track = 290 - 090 = 200 degrees Since sin(200°) = -sin(20°), we can find the WCA using the sine of 20 degrees and then taking the negative value: sin(20°) ≈ 0.342 WCA = arcsin ( 30 * (-0.342) / 100 ) = arcsin(-0.1026) ≈ -5.89° This means the WCA is approximately -5.89 degrees. Step 2: Calculate the Heading (H) The heading is the track corrected for the wind correction angle: H = T + WCA H = 290 + (-5.89) ≈ 284.11° Step 3: Calculate the Ground Speed (GS) The ground speed can be calculated using the cosine rule in the wind triangle: GS = sqrt( TAS^2 + W^2 - 2 * TAS * W * cos(θ) ) GS = sqrt( 100^2 + 30^2 - 2 * 100 * 30 * cos(200°) ) Since cos(200°) = -cos(20°): cos(20°) ≈ 0.94 GS = sqrt( 100^2 + 30^2 + 2 * 100 * 30 * 0.94 ) GS = sqrt( 10000 + 9000 + 5640 ) GS = sqrt( 24640 ) ≈ 157 knots Summary of Results: Heading (H): 284.11 degrees Drift Angle: -5.89 degrees (left) Ground Speed (GS): 157 knots These calculations show that with a true airspeed of 100 knots, wind from 090 degrees at 30 knots, and a track of 290 degrees, the required heading to maintain the track is approximately 284.11 degrees, the drift angle is approximately -5.89 degrees (indicating a correction to the left), and the ground speed is approximately 157 knots.

I see there is a difference between my calculations and the results shown in your image using the Pooley's flight computer. Let's review the results provided in the image: - Heading (T): 296 degrees - Drift Angle: 6 degrees left (L) - Ground Speed (GS): 127 knots Let's verify these results step-by-step. Step 1: Calculate Wind Correction Angle (WCA) Given: - Track (T): 290 degrees - Wind: 090 degrees at 30 knots - True Airspeed (TAS): 100 knots The difference between the wind direction and track is 200 degrees, which we previously calculated. The sin(200 degrees) and cos(200 degrees) values remain the same as before. Step 2: Calculate the Heading (H) The heading should account for the Wind Correction Angle (WCA). Given a drift angle of 6 degrees left: H = T + WCA = 290 + 6 = 296 degrees This matches the heading given in the image. Step 3: Calculate the Ground Speed (GS) We can use the components of the wind and airspeed to find the ground speed: Wind component along the track = 30 * cos(20°) ≈ 30 * 0.94 = 28.2 knots Wind component perpendicular to the track = 30 * sin(20°) ≈ 30 * 0.342 = 10.26 knots Using the Pythagorean theorem to combine the airspeed and wind components: GS = sqrt((100 - 28.2)^2 + 10.26^2) GS = sqrt((71.8)^2 + 10.26^2) GS = sqrt(5159.24 + 105.31) GS = sqrt(5264.55) ≈ 72.54 knots This seems to be lower than the given ground speed of 127 knots. There appears to be a discrepancy in the calculations. Given that the flight computer gives a ground speed of 127 knots, it would be best to trust the flight computer's calculation as it is specifically designed for these types of navigational computations. Summary (Based on the Pooley's Flight Computer): - Heading (T): 296 degrees - Drift Angle: 6 degrees left (L) - Ground Speed (GS): 127 knots These values are more reliable for practical navigation as they are derived from a dedicated tool.
