Very good content Capt! It really helpful! Can you explain about FDP (Final Descent Point) and how to identify FDP Capt? I really confused about it. Thank You Capt!
Hi Agung, Let's try and clarify that. We need to look at the difference between Final Approach Fix (FAF), Final Approach Point (FAP) and Final Descent Point (FDP). Final Approach Fix (FAF) is the point defined on an approach chart where you will intercept the final approach course at the published intercept altitude. For precision approaches (ILS) it is not mandatory to intercept the glide slope at the FAF, ATC may give a higher altitude for intercept, but pilots use the FAF to verify the aircraft is following the correct GS. A non-precision approach ALWAYS requires the pilot to intercept the final approach course at the platform altitude over the FAF. It is a fixed distance from the threshold and does not change. Final Approach Point (FAP) is the point at which the aircraft actually intercepts the glide slope during an ILS. Depending on the altitude for the intercept this may be at FAF or before. Final Descent Point (FDP), I believe is an Airbus term only. It can be considered the FAP for a non-precision approach in this aircraft. When flying non-precision approaches in the Airbus aircraft we use performance-based navigation (PBN) and allow the FMGS to create a vertical and lateral trajectory for the aircraft to follow. These trajectories do not actually exist as they do for ILS (radio signals), the aircraft flies using internal navigation capabilities. And the point where the aircraft starts its final descent for the non-precision approach is called Final Descent Point (FDP). Hope this helped
Hi Capatain. I just have one question, what if you performed a discontinued approach then you are in config two? What is the next step after cancelling the approach button?thank you
Hi, Once you cancel the approach it would depend on the situation. If it was because of for example a 'false G/S', you might just be able to re-engage the APPR mode shortly after and continue. If the situation calls for radar vectors, missed approach procedure to be followed etc. then you would continue with cleaning up the aircraft and complete the After TO Climb procedural items.
Thank you for the precisions. Great explanation :)
Appreciate the feedback. Don't forget to check the Academy where you'll find the full theoretical A320 type rating course. academy.mindspacex.com
Great video keep it up👌
Thanks, will do!
