Transponder setting of 7700 Indicates a general emergency. What that means is for example no gear, instrument failure, stuff like that. But one has to remember that they need to fly the plane in an emergency, and only adjust the transponder if you have time to.
The stamp on the setting indicates the purity of the metal used in the setting, while the absence of a stamp on the ring itself may be due to the design, size constraints, or the method of manufacture. As long as the setting is stamped with the appropriate hallmark for sterling silver, you can be confident in the quality of the piece.

The transponder code set on the aircraft's transponder would be 7700.
7500, 7600, 7700.

0.7% of 7700 is 53.9. One easy way to solve this is to multiply 7700 by 0.7%, or 0.007.
623 divide by 7700 = 0.0809090909090909
77 as a percentage = 7700%77= 77 * 100%= 7700%
(10 percent) percent of 7700 = 7.7
7700 = 7.7*103
ATC codes identify each individual aircraft. They are 4 digits long and are programmed at the start of each flight onto the aircraft's transponder. Once airborne the transponder sends information back regarding the aircrafts position, altitude etc so that ATC can keep track of them. The transponder also 'speaks' to other aircraft transponders and provides information to the aircrafts anticollision system. The only codes not used for aircraft are 7500, 7600 ad 7700 which are emergency codes.
