El Rubio uses light aircraft to transport his many "goods and services" to the mainland. You disguise yourself, they let you land no problem. They will frisk you for weapons though. You want to fool them, you must pay someone to stash weapons on the island, and collect after you arrive.

— Pavel's briefing on the planning screen.
Velum is a prep mission featured in Grand Theft Auto Online as part of The Cayo Perico Heist update, and a freeroam mission that can be completed at any time while The Cayo Perico Heist strand is active. It is one of six missions within the Approach Vehicle category that is mandatory for completion, but becomes optional if another of the missions has been completed.
Mission Details: Steal one of El Rubio's smuggler planes to use as an approach vehicle when infiltrating the island.
Heist Impact: Land on the island's airstrip in the Velum while disguised as one of El Rubio's smugglers. While unarmed, guards will let you travel around the airstrip but will attack if they spot you elsewhere
Pavel informs the player that if they wish to conduct the heist with a Velum 5-Seater, they will need to steal one from some of Juan Strickler's drug smugglers. He quickly informs them that some are currently conducting a drug deal with some dealers at an airfield.
Completing this setup allows the player(s) to approach Cayo Perico in finale using a Velum 5-Seater. Hiring the "Weapon Stash" option from the Support Crew list is not mandatory, but ensures no detection from the guards upon starting the heist finale with this approach vehicle selected.
“
We cannot land on Mr. Rubio's island in just any plane. We need something familiar to them. So, I have been tracking one of his regular planes back and forth, back and forth... and right now we have perfect opportunity to strike while it has landed for a deal. Then we do our best impression of hardened smuggler, and take a visit...

— One of Pavel's briefings.
The player is instructed to go to the location of the plane, which is guarded by a pair of smugglers who are presently conducting a deal with local drug dealers. The player simply needs to take out all enemies in the area and take the plane.
Once the plane is acquired, they are instructed to bring it to Miguel Madrazo's private hangar at LSIA. The mission is completed once the player parks the Velum before the hangar's doors.

Alternative:
You know the advantage of Mr. Rubio being one of the largest exporters in Caribbean? Very regular flights! Good for his customers, and also... good for us! One of his planes is in San Andreas now... probably doing a deal. If you steal it, it will be perfect entry route.
The player nears the location of the deal.
Pavel:
Okay, you are not far from their landing point. The deal will be close... be careful.
Alternative:
The plane's landing point is up ahead. The smugglers will be close.
The player arrives at the location and interrupts the deal.
Pavel:
Hmm, they are not happy you have interrupted their deal?
Alternative:
Aha, they pleased you are there, by the sound of it!
