Doug and Billy have landed at KISP on their way from N12, but are there only briefly. They have to get their clearance before proceeding onto KOWD. They are cleared via the Long Island 5 Departure (SID) from Islip's Runway 24 at the Runway 33L intersection. Although the controller does give them the departure frequency and initial altitude that's actually redundant information. The SID has it all.

Scroll down for a video of the clearance, departure and initial vectors from ATC after takeoff as well as another video from CloudAhoy and relevant Jeppesen plates from KISP.

View from the pilot in training. What I learned...

"This was my first intersection takeoff from a controlled airport and admittedly it was confusing. I expected that we'd need to backtaxi but with a 7,000' + runway this is not necessary. As a pilot in command we can request such procedures provided we're comfortable with the situation. The additional element of the takeoff from KISP was the SID. The controller cleared us via the Long Island Five departure. Before the ECIE I'd never flown a standard instrument departure (SID) but it's not only simple to follow it's a time saver. Everything is there right on the chart.

The controller asks us to expedite our climb. This is where knowing your numbers helps. We know that 10º will set up Doug's Cardinal for a best rate climb speed of 82 kts and close to 1,000 fpm."
