Cessna tech details needed for author
 
Hello, my name is Luis.

Here's the thing.. I'm writing a book, and there's a chapter where this character gets to fly in a private plane (Cessna Citation XLS, exactly) from Caracas, Venezuela (CCS) to Miami, USA (MIA).
https://en.wikipedia.org/wiki/Sim%C3...ort_(Venezuela)

I checked it, and it is about 2,183 kilometers away so, my question is: how much time would it take this plane to get to Miami?


Thank you in advance.
Farewell.

NOTE: My sincere apologies if this is not the right place to post such a thread, I was kind of lost on this matter. I hope you don't mind. ;)

NOTE2: I'd also like to know how much speed would it need to takeoff? I have read books and heard youtube videos where they announce like, for example, 60 knots to takeoff, then, later on the runway, they start shouting: 40 knots... 50 knots... 60 knots...
Well, you must know what I mean by now, so I cut the BS, sorry.

Welcome to FT, luisoliveirav!

There are lots of factors that determine performance, but according to the XLS performance data at http://jetadvisors.com/citation-xls-performance/, a 1,000 nm (nautical mile) trip should have a flight time of around 2:26 (assuming no wind). Since your trip is about 1,180 nm, figure on close to 3 hours in a no-wind condition.

Takeoff speeds will also vary based on density altitude and weight. I found one example of a 106 knot rotation speed from ICT (1,333 feet MSL). From a bit closer to sea level (CCS is 235 feet MSL), you're probably looking at a rotation speed of somewhere between 100 and 110 knots, with takeoff happening about 20 knots above that.

Note that all these numbers are speculative ballpark numbers, as it's impossible to get more accurate without more data and operating handbook data.

Around 3 hours with takeoff speed above 100 knots.

Thank you guys, your help is invaluable. You're worth my respect.

I understand you can't give me exact numbers though, but it is not a big deal because, as I said, it is one chapter where this whole thing happens, the rest of the time he travels on commercial flights, and it is not an aviation book either. :D

So, to sum it all up: the whole trip would take somewhat three hours non-stop, and my takeoff speed dialogue would be something like, 50 knots... 70 knots... 90 knots... *takeoff*. Alright?

Other advantage to flying private are that you can bypass public terminals, other passengers and security. You can arrive at your departure point (typically a private aviation terminal or FBO) minutes before departure. The plane waits for you. On most arrivals, you similarly arrive at an uncrowded private aviation terminal. If you request in advance, a driver and vehicle will meet you plane-side to take you to your final ground destination.

Here are some trip reports with pics of some recent private flights we've taken.

Quite interesting information, thank you.
Nevertheless, does it mean that the departure point can't be the main International Airport, i.e. a public aviation terminal?

Thank you, quite interesting information over here. But, my departure point may be a public airport yet?

You'd probably hear something more like "rolling ... V1 ... rotate ... V2 ... gear up". You probably wouldn't hear actual numbers.

Shouldn't it be
Captain: "Runway heading and elevation checked"
Co-Pilot: "Checked"
Captain: "Takeoff, your/my controls"
Co-Pilot: "Your/My controls"
PF: Sets power level, "Power set"
PNF: "80knts"
PF: "Checked"
PNF: "V1"
PNF: "Rotate" (or VR), PF rotates x degrees
PNF: "Positive climb"
PF: "Gear up"
PNF: "Gear up selected", Switches gear up lever
PNF: "Gear up and locked"
...

V2 calls are not made with all airlines/plane types as far as I know.

Anyway, probably slightly different procedures in different parts of the world.

For the OP, I guess if your book is not targeting plane nerds no one will notice that the cock pit communication is not 100% realistic or the timing is a bit off as long as you do not make a 3 hours flight a 12 hours flight.

Otherwise google for: "Take off roll call outs"

Unless your character is the pilot of co-pilot, the only think he'd hear on a private jet is "Sir, what would you like to drink?"

Sure, you can depart from a public airport, but it would be from the private aviation FBO terminal, typically not part of the main terminal.

You can watch it here from about the three minute mark -

I have taken a private plane from the main airport here in town--but it's from a separate general aviation terminal. You don't board through the normal gates.

A thought here: Unless the plane is big enough to have two pilots there's no reason for calling speed at all.

A Cessna Citation jet will normally always have two pilots in the cockpit.
