Nice. Just adding that the GRAD corrections are ONLY used when OAT< to the temperature of the first line (highest weight) as stated in FCOM PER-TOF-TOC-18-10: ..."In some cases, it may happen that the first temperature value (displayed for the highest weight entry) is higher than OAT. In this case, it is allowed to extrapolate the weight value to avoid unnecessary penalty. Use the Grad 1/Grad 2 gradients provided at the bottom of the corresponding column." this is to get a better MTOW. The A4 as not enough space to put all the weight/temperature info so we have to extrapolate :)
well, first of all thanks for the great efforts for explaining this....second, How to calculate the V speeds at any given RWY? Should we have those charts? if yes, where could we find them? Thanks in advance
These are the charts which help you find v speeds, it will be specific to a runway and intersection. You cannot find them anywhere, it is given by the company.
If ***/*** is given it means no grad corrections can be applied because the temperature in the box at the top in the same column is way below TREF to be able to add any weight to compute MTOW.
Can you please make a video tutorial on how to compute for the landing distance using the QRH? I've been searching on youtube and google but i can't find a really good explanation or video. It would really help a lot if you did. Thanks sir!
Just wondering, if we could use a chart with more Temperature Options.? Like i have been using the Runway Analysis charts from APG, for Airbus A318 and Embraer E190, we have option to select "full temperature". If we select it, it will produce the chart with -20 Degree or so to all the way upto 50 Degree. So we can avoid painful calculation of Grad.?

Thank you Captain for this absolutely amazing explanation. It makes each the FCOM much simpler and easier to understand.
You saved my day and made the preparation for the performance test easier. Appreciate it!
You're welcome

All correct.
Since our structural MTOW is less than the performance MTOW, do we carry on the takeoff with 146/47/48 as our final speeds from this chart?

Hi, What if the GRAD1/GRAD2 correction is given as ****/****. what does this mean?
If ***/*** is given it means no grad corrections can be applied because the temperature in the box at the top in the same column is way below TREF to be able to add any weight to compute MTOW.
@@poh thank you sir
How to get rtow charts for other airports like Kolkata ,Guwahati etc etc
You can't get it, it's an airline thing
@@poh 😭😭😭.
@@poh do pilots have access to these charts or only despatchers ?
@@anikbhowmick1044 Both pilots and dispatchers have access.

+Justin Basco I will be doing that too. Just stay tuned in and subscribed, you'll automatically get notification when the video is uploaded. :)
Thank you so much!! :)

+jesil rahman Yes you can use that, grad correction won't be applied then. Simple as that. 🙂
sir why didn’t you do a speed check after two steps?
It's not needed because you anyway can't go below minimum speeds.
Were you can find this charts for example scel
Generally given by the company that you'll fly for. Not available as an open source.
Planes Over Head thanks !!!
Planes Over Head and you know a app for Ios for calculate this ???
Thank you , great explanation.
You're welcome!
Thanks 😊 🙏
