Would a Boeing 737-900 typically cover more or less than 150 km (93 miles/81 nm) in 16 minutes from take-off?

I'm uploading a picture, and would like to know if it was taken in Spanish or French airspace. The distance from BCN to the border, including a southbound departure and turn, should be about 150 km.

Thanks,

Peter

Never mind. Flightradar24.com says we should just have crossed into French airspace, from Andorra.

Im sure it would do 150km in under 16 min

150 km in 16 minutes is about 300 knots, well within the capability of a 737. At cruise, it would be going considerably faster than that.

Yep guys but notice the question is, whether the airplane can be 150kms away 16 minutes after departure.

I would still say yes, especially if the airplane in question got highspeed under 10K approval, but it is not clearly so anymore.

But it wasn''t cruising.

You don't need high speed under 10000ft to cover 150km in 16mins.

At 250kts IAS at 10000ft, the TAS of the aircraft is 300kts. That is well within the capability of virtually all airliners. Even using a conservative climb rate. You'll be at 10,000ft within 5 mins after takeoff.

Yes, I know. My point was that, since it's going considerably faster in cruise, making it from departure during the climb/acceleration phase isn't an issue either.

Okay. I guess the initial turn was wider than I thought, making the distance larger, so I guess you're right.
