  • IAF and FAF have nothing to do with the final descent.

    By following the above (Flybe), 3 nm from TOD you prepare the aircraft to be ready for the final descent.

    If you do it too early you are going to use more TRQ and more fuel as you'll have more drag.

    If you do it too late you are not going to be ready on time for your descent and you'll have to increase your ROD to follow the path.

  • 3 nm from TOD you prepare the aircraft to be ready for the final descent.

    What your TOD ?

    I don't understand.
  • TOD = Top of Descent

  • Yes i know but you descent landing gear 3 nm before TOD not surely 24000 Alt
  • the TOD of your final descent when you are going to land.
    In your ex: CYYZ around RONTA and CYUL around XULTA

  • In the picture TOD is it red circle or XULTA ?
  • So gear down at XULTA ?
  • Thats it, the red circle.
    You prepare the configuration around XULTA to have the aircraft ready to start the final descent.
    When you do the descent manually with V/S you start about 0.3 Nm before the TOD and adjust (if necessary) the ROD every Nm.

  • I manage to get some screen shots as I could not do a video.

    The FMS are LNAV for the PF and DTO Rwy 05 for the PNF to give the distance to the PF and check the ALT.

    I am using Hpa which is not as accurate as Inches of Hg which could explain that some altitudes are not spot on as there are 28 ft between each Hpa.

    End of downwind leg arriving at SELAP turning towards RONTA. Flaps 15

    About 3 Nm before TOD. Gear - Flaps 15 - RDC Np ldg

    0.2 Nm before TOD GS 145 Kt V/S 800 Ft/mn

    6 Nm 70 Ft below. Adjusting V/S 700 Ft/mn

    5 Nm 90 Ft below. Adjusting V/S 600 Ft/mn. GS reducing to 131 Kt

    4 Nm 90 Ft below. Keeping V/S 600 Ft/mn as reducing speed G/S 122 kt

    3 Nm 70 ft below. Adjusting V/S 500 Ft/mn

    2 Nm 20 ft below. No adjustment of the V/S as reducing the IAS to Vref+5

    1.3 Nm 10 ft above MDA. Vref+5. Minimums

    These screen shots are only a small part of my set up as I use 3 screens and they won't fit in the pages of the forum.

  • If i put flap 10 before gear down i get alert sound.
  • And you say flap 15 3 NM before TOD you put flap 15 10 NM before TOD.
  • Why you descent with V/S instead VNAV PATH ?
  • Before SELAP are you at
    flap 5 ?

    And then do you get down gear before flap 15 ?

    Do you pass from direct flap 5 at 15 ?
    No flap 10 before ?
  • If i put flap 10 before gear down i get alert sound.

    Quite normal, it is designed that way. Flaps 5, then gear down and then flaps 15 (you usually do not use flaps 10 for landing). On my first picture I made a typo, please read flaps 5 instead of 15).

    And you say flap 15 3 NM before TOD you put flap 15 10 NM before TOD.

    It is what I did (picture 2) 9.2 Nm from Rwy. As said above, typo first picture.

    Why you descent with V/S instead VNAV PATH ?

    To have a smoother descent exactly at the TOD instead of having a "roller coaster" decent as I explained in an above post.

    Before SELAP are you at
    flap 5 ?

    Just reaching SELAP during the turn towards RONTA

    And then do you get down gear before flap 15 ?

    Yes, it is the procedure.

    Do you pass from direct flap 5 at 15 ?
    No flap 10 before ?

    That's it.

  • Ok super understand now.
    Thank you so much for your help.😀
  • C'est toujours un plaisir d'aider un lointain cousin du Québec.
