of course not...you have to do a resfreshment course and maybe a jump with an instructor..depends on the dz I guess... You should give your dz a call...they will know what you have to do and how much it will cost ya
If its been over a year, I'd recommend doing a Level 4 and 5 jump again. Taking this much time off is bad, but sometimes unavoidable. Go throught the Frst Jump Class again so that you remember all your emergency procedures again. I'd ask to be put on radio again for the first jump so you at least stand a good chance of hiting the DZ. You're probally looking at an entire day of refresher training before you jump. At least thats what I'd hope I'd recieve if I took that long off from the sport.
A rainy day at the DZ is better then a Sunny day at work
