Balanced Approach Schiphol

Vraag1

1. AMS uses NADP2 without any evidence whether NADP1 or 2 (or anything else for that mater) is actually is better for noise abatement. The answer given in the online meeting was not satisfactory since no evidence of testing between the two procedures was given.
2. On what criteria was the maximum noise level calculated? This is the equivalent of a country side environment and surely other means of transport exceed this limit too. Are these being curtailed too, or is only aircraft?
3. The reduction of aircraft movements will only lead to larger or more densely packed aircraft which in all cases will increase the peak noise level. Again this has has not methodology has not been factually demonstrated. What would the result be if median aircraft weight is increased?
4. There has been no suggestion of implementation of better departure and arrival tracks using modern systems such as RNP-AR or RF These require major investments by airlines and are to be compensated and priority given to aircraft using such techniques. Again, no study was performed or show.
5. The use of Runway 18R/36L gives a significally longer taxi times, even compared to busier airports. This creates more emissions and noise. However, this seems irrelevant to the study as nothing was shown.
6. No attempt to promote reduced engine taxi use in Schiphol was demonstrated.
7. No study was shown regarding the performance of CDO in Schiphol, which is one of the worst in EU countries. The airport needs to be fined when such descent profiles are made impossible.
8. All FAFs are very low at 2000ft MSL while most airports are 3000ft. This gives pilots a low intercept. Shorter approaches can still be given after FAF by ATC.
9. The restriction to be 160KTS until 4NM while improving capacity, it increases noise as the aircraft (A320) requires to maintain high power with landing configuration to be able to decelerate to Final approach speed of approx. 130Kts in the 1nm required to be stabilised.
All in all, several operational improvements are required by Schiphol before any traffic limiting rules are implemented.
