Hi!
I have some questions on the Jeppesen and 744 fms.
Somebody help me.
Q1> On the non-precision app(straight in) charts in US, they have words like "Only authorized operators may use VNAV DA(H) in lieu of MDA(H).". What does this mean?
Q2> Some non-precision approaches don't exist on the FMS database even though they are on the Jeppesen. What is the reason?
Is it because of the size of the of FMS database or accuracy problem of navaids?
Q3>In this case, may we fly the PDB points which are manually entered with alt constraints ,with LNAV (and VNAV)?
Q4>Shouldn't we fly the non-preci app on VNAV if FMS does't have the rwy point for that app?
Q5>WX is CAVOK. You fly the JFK "VOR DME 13L app". There is no Rwy point on the FMS legs page. MDA is 800feet. Fms legs page has 1220feet for MAP which is 3 degree height from 3.6 mile rwy threshold. What altitude will you fly for that app on MAP?
What about the IMC? I think it is very difficult to stabilize heavy 744 in a short time of 800'(700 agl)level flight to 500'agl(company stabilization altitude).
Q6>LAX VOR RWY 25L/R APP
In the landing minima section,MDA FOR 25L "without noele" is 620feet. MDA FOR 25L " with noele" is 580feet.
If FMS leg page doesn't have "noele" between FREBY and MAMMA(MAP), is it O.K. to fly that app to MDA 580' "with noele" manually entered waypoint with alt constraint /620 ?
Q7>Jeppesen charts provide DPA(descent path angle) for most of non-prec app in U.S..
But they don't for Honolulu. Is there any reason?
Q8> Who provide FMA DATABASE for 744?
Does Jeppesen also provide for FMA DATABASE?
I need your help.
Thank you gentlemen. :D
