a) ATC route clearances;
b) clearances and instructions to enter, land on, take off from, hold short of, cross and backtrack on any runway; and
c) runway-in-use, altimeter settings, SSR codes, level instructions, heading and speed instructions and, whether issued by the controller or contained in ATIS broadcasts, transition levels.
Most of that is no surprise but the readback of Transition Level when issued by ATIS is something we haven't really come across from crews in our region (Southern Africa). Crews normally advise us of the ATIS information on 1st contact but not TL, however when descended through the TL (usually FL110 here) ATC changes the instruction from Flight Level to issue the altitude on QNH.
Is it usual for crews to readback the TL when this is included on an ATIS broadcast elsewhere and how strictly is this enforced in your region?
Pretty sure I've never heard the TL broadcast on any UK ATIS so no need for a readback.
Same process here when changing from an altitude to FL (or vice versa).
