The other day I saw a very nice add on that I was interested in, however I did not write the name of it down. It was airport ground enhancements. Has a taxi car (where you can follow the car to your gate or wherever), then has the guy giving you the hand signals and signals you when to stop and then will chock your wheels. The jetway will come out if you request it. Then the pushback vehicle will push you back so your facing the right direction and then tell you when it is safe to start your engines..I really wish i could remember which add on this was. Any one have any idea?
