However, although it makes sense, pilots are not required to acknowledge or
read back a take off or landing clearance.

I dunno what country you fly in, but I am talking about New Zealand,
and the rules here are obviously somewhat different to wherever you
fly..

On the NZ CAA website, you will find:

Advisory Circular AC 91-9 & AC 172-1

This is from the appropriate section of that document:

4.12 Readback Requirements
4.12.1 A pilot is required to acknowledge receipt of the following ATC
clearances, information or
instructions, which are transmitted by voice, by a full readback
followed by the aircraft callsign:
· ATC route, approach and departure clearances including any amendment
thereof;
· clearances to VFR flights to operate within controlled airspace,
including entering or vacating the
circuit;
· clearances (including conditional clearances) to operate on the
manoeuvring area at a controlled
aerodrome including:
o clearances to land on or take off from the runway-in-use;
o clearances to enter, cross, or backtrack on the runway-in-use;
o instructions to remain on or hold clear of the runway-in-use;
o taxi instructions including a taxi route and holding point where
specified;
· runway-in-use;
· SSR codes;
· level instructions;
· heading and speed instructions;
· altimeter settings; and
· frequency, after frequency change instructions.



This relates to Part 91 of our CAA rules, and is exactly what we were
taught when getting our licenses.
