There are two things you need to do right after takeoff, just as a matter of getting the airplane converted from ground vehicle to air machine, and there is one thing you need to do just as a matter of keeping safe. Everything else can wait. How long can it wait? Our answer is 10,000 feet but there are other views.
[G450 Airplane Flight Manual §2-05-10]
- GND SPLR . . . OFF
- Gear . . . UP
- Flaps . . . UP
- Guidance Panel . . . SET
- Climb Power . . . SET
- GND SPLR . . . OFF
- CABIN PRESSURE CONTROL Panel . . . CHECKED
- EXTERIOR LIGHTS . . . AS REQUIRED
- SEAT BELT / NO SMOKE . . . AS REQUIRED
- Altimeters (3) . . . SET & CROSS-CHECKED (AT TRANSITION ALTITUDE)
- APU (If Running and Not Required) . . . SHUT DOWN
There are generations of Gulfstream pilots who rightfully connect the ground spoilers switch with the gear handle, knowing that bringing the power levers towards idle with a Weight on Wheels System Failure can be fatal. Like them, I used to always select gear up and then ground spoilers off. But what happens if you do have a Landing Gear Failure to Retract and the gear handle doesn't come up? Won't you be confused enough to forget the ground spoiler switch? What's the next thing to happen if the gear is stuck down? Chances are the guy in the left seat is going to be leveling off pretty soon to bring the airplane around for a landing. When he does that the autothrottles are going to bring the power levers back. If the WOW is in the ground mode, those spoilers are coming up, aren't they?
I usually wait for the altimeter to start climbing, the VVI to head north, and a visual confirmation that we are heading up. That usually takes a second or two. If you didn't do so in step 0, immediately turn the ground spoilers off. Sure, there are several systems designed to keep the spoilers stowed when airborne, but connecting the spoilers to the gear handle in your procedures only takes a second and it can save your life if other things go wrong.
Limit bank angle to 15 degrees while retracting flaps until reaching V2+20.
[14 CFR 25 §25.111(4)] The airplane configuration may not be changed, except for gear retraction and automatic propeller feathering, and no change in power or thrust that requires action by the pilot may be made until the airplane is 400 feet above the takeoff surface.
[G450 Aircraft Operating Manual §06-02-40] Flap retraction: "at 400 ft abv airport level (AAL)" but it also notes: "Consideration should be given to delay flap retraction during heavy weight takeoffs/turns/terrain avoidance in order to retain takeoff power setting."
Some pilots argue that 14 CFR 25 is for aircraft manufacturers and they don't have to follow the 400' rule. I wonder why they are flying their airplanes outside of the design criteria. Some flight departments use 1,500 feet for all takeoffs. We use 400 feet, as the AOM says, unless there are other considerations, such as a Noise Abatement Procedure or obstacle clearance considerations.
This step should be item 2 at the latest, item 0 for me.

In cabin pressure AUTO you should see the cabin altitude start and the differential pressure increase. In MANUAL you should at least see the differential rise. Don't bother with the synoptic, there is a gauge right above your head.
We normally get the landing lights off at 10,000 feet and the pulse lights at 18,000 feet.

To answer another frequent question: yes I live in fear of law suits and have reached out for permissions where possible. Gulfstream has been very good about all of this provided I add the note shown below. Let me be clear about this: I think the world of Gulfstream Aerospace. There is no prettier wing in existence than what you see on a GV or G550 and the best cockpit I've ever touched is in my trusty G450.
