The crosswind math is genius as is the crab angle. Thank you very much for that.

Captain I have a question regarding the XWC. What if I encounter the situation of a tail wind. And it is above 90 degrees diference. Example: HDG 290 Wind from 170/20 290-170= 120 degrees difference 180-120= 60 degrees With the graph you provided 60 deg is WIND -1 so: XWC = 20-1 = 19 WCA = 8 degrees to the left HDG CORRECTED 288 degrees Is this simplification correct?

The DME ARC rule can be used for NBD arcs as well?

@ATPLStudent 7 ай бұрын

Of course it can, provided you know the radius of the arc (how far away the arc from the NDB) if it’s about 13/14/15/16 miles then you may use the rule of thumb as explained in the above video.

How can you assume the WCA is half of the crosswind component without taking into account your airspeed? Your example would only apply if your were flying at 120kts. Any other speed and you'd have to apply a different w.c.a..

@ATPLStudent 10 ай бұрын

You are right, that is why I mentioned that that method is applicable mostly for General Aviation and single engine low performance aircraft where the TAS is about 100 to 130 kts

@bruno84 10 ай бұрын

I didn't see you mentioning it. That's why I commented so that people wouldn't think it would be always half the crosswind coponent. Anyway one easy rule to calculate your w.c.a. with any aircraft and speed is to divide the crosswind component by your speed in Nautical Miles per Minute. E.g. 120kt = 2nm/min. Given a 20kt crosswind: 20/2 = 10 degree w.c.a. 300kt (5nm/min) 20/5 = 4 degree w.c.a. Easy to apply to any speed. Still, thanks for the video!

Are calculators allowed when factors like sinus come in play? And are basic calculators there in the interviews, or is it purely mental! Thanks for the vid btw!

@ATPLStudent Жыл бұрын

You hardly ever get to use sin and cos in flight, there are many rules if thumb for most of the calculations needed in flight, so don’t worry about that. As for ground school especially in Gnav and Mass and balance you are allowed to use a calculator. In interviews they only expect you to know rules of thumb and 1 in 60 rule and other very basic mental calculations just like the ones demonstrated in the video above.

Why did you mulipl GS*5 for rate of descent. Just trying to get an understanding of where you got the 5 from and not any other number?

@ATPLStudent Жыл бұрын

It's a rule of thumbs for easy mental math. it comes from the glide path in percent 3 degree glide path = 5.2% so it is actually GS x 5.2 but we drop the 0.2. If you want to go deeper of where it comes, you will find out that it comes a result of basic trigonometry

Why do you divide by 4 on the DME arc ?

@ATPLStudent Жыл бұрын

Because of the 1 in 60 rule. For a 60 NM DME Arc each degree is1 min 30 NM DME Arc each degree is 30 sec 15 NM DME Arc each degree is 15 sec and since this calculation is merely a rule of thumb we consider 12/13/14 all as 15NM DME Arc. because of 15 seconds is 1/4 of a minute we multiply by 1/4 or simply divide by 4 the difference in radials. Hope this has clarified your doubt

Did I miss something how did you get FL260- FL110= 15000ft- isn't cruise altitude 5500 minus target altitude 1500 would be 4000 Which would make rate of decent 4000/10= 400

@ATPLStudent 6 ай бұрын

I think you are confusing two examples with each other. FL260 is 26000 and FL110 is 11000. So, 26000 - 11000 = 15000 Got it ?

5:33 Your calculation does not match exactly. This is correct; 5500-1500=4000ft GS120KTS 120kts/60h=2nm path per munite 4000ft/600fpm=6,66 minute (descends in 6.66 minutes with 600fpm) 6,66*2= 13,32nm. (it make progress 13.32 nm in 6,66 minutes at 120 kts.)

@ATPLStudent 10 ай бұрын

You are using two different methods at the same time. you wont get the correct answer that way. I see the point you're trying to make here but that method of your corresponds to high altitude/high performance aircraft where during the descent the GS changes. if you are looking for Propeller/Low Altitude operations stick to the method in the video it's pretty accurate to manage your VNAV profile/TOD. thanks for your comment

@1Mr.Legend1 10 ай бұрын

No, I just calculated it on 120 kts. The process changes if we take wind into calculate. You shared a method without taking the wind into calculate, but it was not exactly correct.@@ATPLStudent

GIVEN: True course : 105 degree , True heading : 085 degree , True airspeed : 95 kts , Groundspeed : 87 kts. Determine the wind direction and speed. (A)020 degree and 32 knots. (B)030 degree and 38 knots. (C)200 degree and 32 knots. According to u video the answer should be (B) but the answer is A why?

@richievaldez3607 Жыл бұрын

105-085= 20 degrees 95-87= 8kts crosswind According to table, 20 degrees is closer to 15 degrees off track = 1/4 of wind speed so: 8x4= 32kts wind speed So answer (A) is correct.
