@@tarunshalini1180 understood thanks! It's because ISA temperature between 11 to 20kms is -56.5°C whereas the actual temperature @ 14kms is -62°C. Hence ISA deviation is -62 - (-56.5) = -5.5°C. Which means Actual temperature is 5.5°C colder than ISA.
we know temp temp decreases as we go up and increases as we go down at the rate of 2*C/1000Feet Now do the maths. Answer would be fl300 for 11*C For question 2 Temp remains constant between 11km-20km = -56.5 C So -62-(-56.5) = -5.5
Hey I literally enjoy all of your videos. Thanks 🙏 It helps me a lot. I can bet no one could simplify Aviation topics soooo smooth as you do. Would you mind, I want to take classes from you? Please answer...!!!
Sir, In question 4, Isn't the temperature at FL300 = 48°c should first be converted to ISA temperature????? because the ISA temperature at FL300 is not 48°c.
@yashbansalvlogsIf you directly apply formula to find the answer you will get 4000ft ie actual. Need to apply the correction of 2° ie 1000ft to the answer... For that solve the first part of the question...you will get ISA deviation as 2°C Now while solving 2nd part...subtract 2°C to the given temperature ie 11°-2°C = 9°C (Actual-ISA) So the equation will be 9°= 15- (alt/1000×2)....6×500=alt ie 3000ft
Hey, for the topics that i have covered, i can guarantee that you'll face no difficulties in answering the questions, but there are some topics which are very straightforward and thus I have not made videos on those. If you go through those chapters from the book, I'm sure you'll pass the exam with flying colours! Wishing you the best.
Eagerly waited for this video. Finally watched and completely understood. The answer for 1st question is 2000ft. I know the answer for 2nd question is not correct but what I am getting is -5.5°C. Expecting more videos like this sir.
That’s great. The answer to the first one should be 3000ft. I think there’s a calculation error, check it again😄. The second one is correct! It’ll be -5.5 👍🏼
For your questions, FL should be 20 right instead of 30. As every 1000ft, it decreases by 2 degrees. So from 15 degrees at MSL, it should be 11 degrees, which means we subtract 4 degrees for 2000ft. In the video as well, at 10.08, you calculated temp at 2000 ft to be 11 degrees. Am I missing something here?
first of all thanks a lot for this type of videos . These are really helpful and really informative , Keep going . my question is that according to IC JOSHI tropopause has lapse rate of 1-2 degree C per km. so what should I consider the lapse rate of 1-2 degree C per km or constant temperature of tropopause? please clarify this .
Hi sir, i had recently appeared for my composite paper for PPL and scored 69/100, missed by 1 mark. A lot of the questions were bot even a part of PPL and had questions from instruments, can you guide as to what nore should i incorporate in my studies to clear it in the next attempt. Thankyou
Sir, I’ve a doubt it’s from OXFORD’s first chapter, Q6th…it will be great if you can help. [ At a certain position the temperature on the 300 hpa chart is -54^C, and according to the significant weather chart the tropopause is at FL330. What is the most likely temperature at FL350? ] how to calculate altitude by pressure ?
Hi, sorry for the late revert. So if you want to find altitude according to pressure, you can use the ISA pressure lapse rate. Take the pressure at whatever altitude is given in the question and then apply the lapse rate of pressure given in ISA. the same can be used with temperature to find altitude according to temperature, by using the temperature lapse rate. Go through the questions I have discussed in this video and you should be good!
Find the ISA Temp at 2kms (using the ISA Lapse rate ie. 6.5 deg C per 1km) and then you’ll have the ISA temperature (that you found) and the actual temperature (that is given in the question ie. 5deg C). Find the ISA Deviation (actual temp- ISA temp)
Hi, sorry for the late reply. So, use the ISA temperature lapse rate. You know the temperature at a certain altitude (given in the question) and you know the lapse rate (how much drop/gain in temperature is experienced by gaining/losing altitude. Keep in mind that when you go up, the temperature falls in the troposphere and when you come down, the temperature increases. Just use these basics and you'll be able to get the answer!

1) 3000ft
2) ISA deviation is +14°C (Actual temperature is 14 degrees warmer than ISA temperature).
Second answer should be 5.5 degree Celsius... Carefully see

@@dineshbabu1611 thats correct!🙌🏼
initially i got same answwer ans didnt realised the fl is 14km which has constanyt temp ..
@@tarunshalini1180 thankyou for finding the mistake i did the same mistake as @DineshBabu
1) 3000ft 2) -5.5 degree Celsius
2) how to solve this question
we know temp temp decreases as we go up and increases as we go down at the rate of 2*C/1000Feet
Now do the maths. Answer would be fl300 for 11*C
For question 2
Temp remains constant between 11km-20km = -56.5 C
So -62-(-56.5) = -5.5
Thank You so much for this video, it'll be really helpful if you could make more videos on Met
Sir you are doing great. Please make video more for learning it would be very helpful for us .
Thank you! Yes I’ll be posting more soon.

Just check your answers again, first one should come to be 3000ft and the second one will be -5.5 (tropopause)!
@yashbansalvlogsIf you directly apply formula to find the answer you will get 4000ft ie actual. Need to apply the correction of 2° ie 1000ft to the answer...
For that solve the first part of the question...you will get ISA deviation as 2°C
