Mode S Traffic Alert and Collision Avoidance System Description and Operation, TCAS System Troubleshooting, Revision A July 1990 for Training Use Only.

Payment

• Payments must be made through eBay's payment services within 7 days of the sale. (If you need more time, please contact me and let me know.)
• Failure to pay without a response to communications will result in an Unpaid Item Claim against you. Please pay and/or communicate any delays to me within the 7 day period.
• International Buyers: Buyer is responsible for any taxes and/or customs fees associated with this sale.

Item Information

I do my best to describe the items in text and photos, but additional questions are always welcomed. Contact me if you would like more details or want to see photos from different angles.

Shipping

• Items will ship within 2 business days after cleared payment is received.
• For most items, they will be shipped in a plain bubble-mailer (exceptions being for anything fragile or breakable). I will gladly pack an item in a cardboard box for extra protection at your request, but this may delay the actual shipping slightly.
• If you want shipping insurance, I suggest paying for Priority Shipping (USPS Priority Mail has up to $100 insurance automatically). For items over $100, contact me prior to paying and I will get back to you with the shipping price including Insurance.
• International Buyers: It is fraudulent to mark the shipping documents as “Gift”. All items shipped internationally will be marked as Merchandise. No exceptions.

Return Policy

• Returns will ONLY be accepted if the item you receive is Dead on Arrival (for anything electronic) or if it was not as described or grossly misrepresented (if you have questions about the item, please ask them before buying).
• Returns will NEVER be accepted for a buyer changing their mind or for an item arriving broken or damaged during shipping when Shipping Insurance WAS NOT purchased (see Shipping section above).
• Buyer is responsible for shipping charges to return item. Refunds will NOT be given until the item has been received.
• If you have an item that meets the above criteria for return, you must contact me first within 30 days of receiving the item to begin the return process.
