Learn how to survive with the only supplies near.
All types of food are available in the desert. If you're willing to eat and catch them. For starters there is the yummy camel. Now all you will need is a fire. Also make sure that any supplies in the plane that you can use are available to you. Any sharp edged plane parts would work great for killing. You can also practically eat anything else too.
If you want water find a cactus and take the water from inside of it or find a lake, pond, or ocean. If you have none of these things then you are pooped out of luck.
To have shelter you need something that will keep you warm. There are two options, you can either use the supplies of the plane or kill a camel, go inside of it, then have a perfectly good night's rest.
