Do any experienced survey pilots have any tips for those of us about to start this season? It's a pretty unique lifestyle - is there anything you wish you would have known before you started? For instance, any suggestions on how to handle mail, laundry, nutrition, etc. Do people bring video games, guitars, etc for entertainment? You get the gist.
Mail- if you need anything sent to you on the road, the best way to do it is to give the sender the address of the FBO you are basing out of. Your name and the tail number of your plane should be included with the address so the FBO will know it's for you. That's what I did if I needed anything mailed, and I never had any issues. However keep in mind that in this job you may be asked to relocate at very short notice, so there is always that risk.
Laundry- I usually just did it at the hotel laundry room, if available. I kept a bag of Tide Pods or Gain Flings in my suitcase to avoid having to spend money on laundromat detergent since it's a usually a whole dollar for one load's worth of detergent (yes, I'm a stereotypically cheap pilot). Some hotels have free washing machines (most commonly extended stay type hotels) so take advantage of that if you stay in one.
Nutrition- I may not be the best person to give advice as I readily admit I do not have healthy eating habits. You will probably end up eating restaurant food a lot. I usually chose local restaurants when possible since they are usually better quality and better value for the price. Since you may end up in parts of the country you've never been to before it can be a good opportunity to try new foods. Some pilots brought small slow cookers or rice cookers with them to cook food in the hotel room. I worked for Air America, which does not provide hotels directly, so pilots are responsible for finding their own accommodations- when it was the best option we sometimes stated in houses or apartments found on Airbnb, VRBO, etc. which had kitchens, which was nice since it was relatively easy to cook your own food and which I took advantage of. Even with hotels extended stay properties usually have kitchens or kitchenettes which allow you to cook your own food as well. You will also be eating a lot of hotel breakfast- expect to be tired of it by the end of the season. When weather permits, you will fly some very long days with little opportunity for a lunch break. I often kept non-perishable snacks in the plane for this reason, usually almonds or other nuts. Sandwiches for later can easily be made from hotel breakfast offerings. Of course, exactly what to do about nutrition will depend on your personal tastes and dietary needs.
Yes, people have brought both guitars and video game consoles on the road. It will be one more thing to carry when relocating/ switching accommodations but is easily doable, and it will provide away to pass the time. You can sometimes go a long time without flying when weather prevents data collection. It that happens, it's also a good opportunity to explore the area you're and do anything there is to do there.
