When to install / remove nose gear pin?

[vdrummer4]

I've completed a few flights in the 650 now, but I'm never sure when to install or remove the nose gear pin. Obviously it should happen while HYD 3A is on, but at what part in the checklist should I do that? What's your procedure?

What seems to make sense for me is removing it after the hydraulic 3A is turned on but before nose door is closed (to satisfy their respective checklist entires). Then put back in after shutdown checklist, but before securing checklist, as this is when the pax are leaving so the door is open, for doing a quick post-flight walk around.

That's basically how I've been doing it as well. I will continue doing so then. Thanks.

As I understand, in the real world I believe a lot of the time they just install the pin, and leave the nose door open between flights.

You can, but doing so could potentially be dangerous. If the toggle switch were to be moved to the “closed” position at some point after the aircraft is powered down, the nose gear doors would immediately close the next time the 3A hydraulic pump is turned on. If somebody was working in the nose wheel well at the time, they could be seriously injured.

On the real airplane, it is actually possible (though not easy) to remove or insert the pin with the door closed. There is enough of a gap between the back of the door and the gear strut. But, one has to have a skinny arm, and a lot of flexibility in the elbow joint!

Yes, I tried leaving the door open once, but got a CAS warning for it.  Kind of an odd juggle jumping out of the airplane just for that in the middle of an already confusing checklist!
