When an ATC gives a couple of instructions to an aircraft that immediately follow each other such as
"N12345, enter straight in Runway 13L"
"N12345, number 1, Runway 13L, cleared to land"
The aircraft should reply to both in one phrase when they hit ‘Reply’ to say
"Enter straight in Runway 13L, number 1, cleared to land, Runway 13L, N12345"
This would be especially helpful for IFATC during periods of high traffic since it is recommended we wait for the reply to an instruction before sending another instruction. Too often, I will send an instruction to an aircraft and have to wait for a while before they reply. This feature would allow ATC to send a pair of instructions that usually go with each other without having to wait for a reply in between and still have verification for both.
