There was another part to this question that I had figured out. I had calculated the actual airspeed of the plane, which was 207 km/h.

**drwls**, Tuesday, July 6, 2010 at 6:55pmThe information provided can yield ground speed 200 km/h, and the speed with respect to the ground, but not air speed. Air speed is affected by wind speed, which is not given.

Let V be the actual speed along its climbing path, in earth-frame coordinates. This is probably what you meant by "air speed"

V cos 15 = 200

V = 207 km/h

The climbing rate is

Vy = V sin 15 = 53.6 km/h.

To climb 1000 m (1 km), the time required is t = (1 km)/Vy = 0.0187 h = 1.2 minutes
