Procedure; Airspace Structure; Human Factors
Our Clearance was RUUDY 4 Departure and we departed Runway 24. On the departure we were to cross WENTZ at 1;500 FT and TASCA at 2;000 FT. When departing Runway 24 the VNAV was not selected and we may have climbed a little higher than 1;500 FT before WENTZ. After WENTZ we leveled off at 2;000 FT for the crossing at TASCA. The Controller advised us that we needed to cross WENTZ at 1;500 FT on the departure and we asked if we were a little high above the crossing altitude. He replied to us not to worry about it that everything was OK.
An HS-25 Captain failed to level at 1;500 FT at the WENTZ Intersection on the TEB RUUDY 4 because VNAV was not selected for the guidance.
