NADP 2 vs NADP B - Pesky Vzf + 10 kts...

[extreme P]

The Jepp Airway manual states NADP B is no longer part of ICAO PANS-OPS.

In the old NADP B profile (which is now only provided for supplementary information) a speed of Vzf +10 kts must be maintained after initial acceleration to 3000' before acceleration to enroute climb.

In the NADP 2 profile the only speed mentioned after the initial acceleration height is Vzf ("...as the aeroplane is accelerated towards Vzf.")

Does Vzf + 10 kts still apply during an NADP B departure?

[POL.777]

As I understand you are to keep Vzf +10 until passing 3000 agl. Thereafter acc to enroute climb speed.

Vzf ?

As per jeppesen air traffic control 05 jun 09 revision , NADP B

from 300m(1000ft) to 900m(3000ft)
- continue to climb at NOT GREATER than Vzf+10kts

at 900m (3000ft)
-accelerate smoothly to enroute climb speed

so according to this, Vzf+10kts maximum still apply up to 3000ft above aerodome elevtion
