Airmanship and not bickering is the way forward chaps. Your SA of other aircraft clearances as well as your own and ATC profile requirements/expectations should dictate the rates of descent. Particulalry at DXB where different styles abound.
To those on another thread who are arguing that they will fly a dive and drive as they wish as an act of defiance, not a CDA. Well good luck with that at 2000 feet behind a 380 on a CDA. First paragraph refers.
LIDO GEN COM s the companies reference for RT. Not any other. (local CAP notwithstanding).
An example of a local rule.
UK AIP:3.2.2.4 Minimum Rates of Climb and Descent
3.2.2.4.1 In order to ensure that controllers can accurately predict flight profiles to maintain standard vertical separation between aircraft,
pilots of aircraft commencing a climb or descent in accordance with an ATC Clearance should inform the controller if they
anticipate that their rate of climb or descent during the level change will be less than 500 ft per minute, or if at any time during
such a climb or descent their vertical speed is, in fact, less than 500 ft per minute.
3.2.2.4.2 This requirement applies to both the en-route phase of flight and to terminal holding above Transition Altitude.
Note: This is not a prohibition on the use of rates of climb or descent of less than 500 ft per minute where necessary to comply
with other operating requirements.
Further reading in AIP 1.7
Also from CDA guidance:
34.
A minimum rate of descent of 500 fpm is applicable for ATC
purposes for aircraft above the Transition Altitude following
STARs . Although this
requirement does not continue into the approach phase of
flight, some pilots have in the past continued to descend at a
higher rate than necessary. To avoid confusion the UK AIP now
clarifies that the 500 fpm minimum ROD requirement does not
apply below Transition Altitude.
And from the same guidance.:
‘Level flight’ is interpreted as any segment of flight having a
height change of not more than 50ft over a track distance of
2nm or more.
AN ICAO CDA includes 1.5 miles level flight, a UK one 2.5
Germany CRAR. Minumum ROD for CDA 300 fpm.
Now An example of Dubai expectation from the horses mouth. An extract from a meeting between us and them.
Minumum of 500fpm.
Speed +/_ 0Kts
Reduction 10kts / NM when being vectored.
I cant seem to insert the extract from the minutes here, but the speed control is now in the AIP if you care to look with the added caveat that non compliance will be reported to the authority. DL letter advised of this sometime in June 2011 I think.
There are too many Local variations to start a pissing contest. Fly according to where you are and whats required. Paragraph 1 refers.
