Great advice from the other response, so I'll add.
My program has "guidelines" for the ride-a-long to follow, but in case the program that you will be "shadowing" does not:
#1 we use, the others are mine!
1. Generally, non synthetic clothing is preferred and shoes with a hard sole. No denim jeans or scrubs, tennis shoes, no clogs or slip-ons. *I would think that twill pants (Dockers), cotton shirt(s) and a light jacket are essential. Dress in layers - the temperature can vary a lot.
2. Follow directions to the letter. They will give you the safety rules. Follow them! DO NOT touch ANYTHING on the outside or the inside of the aircraft. SAFETY comes first.
3. Style your hair in a simple manner. You most likely will be given a helmet to wear in the aircraft - fussy is not a good look. There is nothing wrong with being attractive, but this is not a beauty contest. Keep it simple and classy. Avoid pins & clasps.
4. DO NOT wear heavy makeup - it gets on everything. I hate to clean it off of surfaces, headsets, helmets - etc.
5. No perfume or cologne. Not even a little. You are in a very small space. This should be a no-brainer, but it is not. Show up all scented and I'll ask you to reschedule and return UNSCENTED. Not trying to be mean, it is a bad practice for patient care. It can also make some folks nauseous.
6. As to the camera, I doubt that it would be an issue as long as you do not photograph patients. Just ask for permission! A pic with you and the flight team, or you with the aircraft is a great keepsake - just email me a copy too! (our program tries to picture everyone that we allow to ride, makes an awesome collage!) Just make sure it is small and not overused. Also, pics from the aircraft are cool - just NEVER use a flash in flight!
7. "Air sick" is pretty bad. Even if you are not prone to motion type sickness, it can still happen. Non-drowsy OTC meds for motion sickness are a good idea from the start. You just never know. Eat light before you start your "shift". For me - crackers with a little cheese or a peanut butter sandwich works well. A ginger ale can work magic. Prevention is easier than recovery!
8. Show up prepared. Research the program and flight services in general. Ask questions - tell them that you are interested in LEARNING! Most of the folks that do flight are the elite of the elite - so they are generally excellent teachers!
Remember, you are a guest in their house. Act accordingly. Have fun. Learn a lot! Be SAFE!
