Noise Abatement Procedure
Can someone quote the DAP or Jepps text defining the NAP to be used by Jets at Aussie Airports?
We use LIDO, and the way NAP is describe is a bit ambiguous- it can be read as being standard ICAO type B (Thrust reduction + acceleration to Vfr at 1000') OR acelleration to flaps up THEN thrust reduction at 1000' (Which would be a local variation).
Are the other Docs a bit clearer on this?

Jepp Terminal section, page AU-13 might have more for you.
Either NADP 1 or 2 are acceptable, or some other method that meets the requirements of PANS OPS Vol 1, Part V, Chapter 3

Err...Yeah...thanks- as I said, I don't have access to those documents, hence the question.
Could you cut'n'paste the relevent paragraph?

Just had a look.
9.1.7 is the paragraph reproduced in LIDO.
It DOES seem to be a variation on NADP B (rather than NADP 2 as it specifies 1000ft, not 800) in that it calls for thrust reduction after flap retraction.
What specific procedures are most Aussie operators using? (I seem to remember we used type A or B on a runway specific basis).

Jepp 10-4 for YPPH states either NADP1 or NADP2.
However alternative procedures are available to aircraft operators with engines having a by pass ratio greater than 3.5:1, climb at V2+10 - V2+20, maintain t/o power setting till 1000', maintain positive rate of climb accelerate to VZF retracting flaps on schedule, then reduce to normal climb power, continue to climb at not greater than VZF+10 to 3000'
