B777 3R MAR2016 BRIEF: RNAV/RNP Good further discussion on the RNAV RNP requirements , Note that there is a requirement to review the Supp Procedure before Jlying an approach and it is a good tool to use just prior to, or during approach brief as it highlights two tasks not covered in the QRH pre-approach notes in the OPS INFO section. Namely; to check the FMC GP angle is within 0.01degree of the charted value, and the requirement to check the altimeter reading across the FF is within 100ft of the charted value. Note in the event of a MAP all speed limits apply so have a think about the management of the A/C at various stages around arrival. Also it is very important that you conJirm LNAV re-engagement ( 50ft if manually Jlown, 200ft with AP ), due to the RNP which on most approaches appears to be 0.3 to the Jirst turn then 1.0. It may be necessary to request vectors if unable to comply with the RNP. A good idea to state what you expect to see when at the minima, and also, what actions are required i.e. are you going to leave AP in until 200ft or Jly manually, FD’s remain on. Unlike LVO approaches where we plan on the worst case minimums for RNP AR where multiple RNP’s are offered we choose the one which will allow descent below the cloud base and within the vis requirements, not the RNP with the lowest DA. I believe the reason being there is a wider tolerance in the RNP value therefore more chance of completing the approach without any deviation alert. KJFK13L Note AP can stay in until wings level and down to 200ft if you like. FDAP data shows short landings perhaps due to 2.75 vasi which shows you high off the 3degree arrival, NB in sim visuals showed on proJile at 200ft. PILOT INCAPACITATION Completed by review of this presentation, not carried out in sim. TCAS NB the new generation software includes “level off” otherwise same same UPPR AIR TRNG Protections and aerodynamics discussion. Note there may be some accompanying dialogue for upset recoveries, we used them in sim and seemed to work nicely. Ie “STALL – DISCONNECT - PUSH – ROLL – THRUST…..STABILISE”. IN SIM: NOTE all approaches Jlown at 250tons with TW so you do the maths!
