Premetto che capisco le perplessita' di Tonik e di coloro che reputano questa "usanza" nociva alla sicurezza del volo.
Ho utilizzato il termine "usanza" con l'intento di sottolineare il fatto che si tratta di una pratica nostrana, come un piatto tipico italiano che trovi solo da queste parti.

Lasciando liberta' di opinione sia a coloro che ritengono nociva questa pratica sia a quelli che fanno del multitasking a basse quote, a basse velocita' in IMC e durante un G/A un valore aggiunto da sventolare, vorrei tuttavia lasciare un paio di letture estratte dal toolkit ALAR di FSF (Approach and Landing Accident Reduction program di Flight Safety Foundation) che dovrebbe essere parte integrante dell'addestramento di ogni pilota e controllore:

Crew resource management (CRM) highlights the relevance
of the context and the expectation in communication.
Nevertheless, expectation may introduce either a positive bias
or a negative bias in the effectiveness of the communication.
High workload, fatigue, noncompliance with the “sterile
cockpit rule,”3 distractions, interruptions and conflicts are
among the factors that may affect pilot-controller
communication and result in:
• Incomplete communication;
• Omission of the aircraft call sign or use of an incorrect
call sign;
• Use of nonstandard phraseology;
• Failure to hear or to respond; and,
• Failure to effectively implement a confirmation or
correction.
Building Situational Awareness
Radio communication should contribute to the pilot’s and the
controller’s situational awareness, which may be enhanced if
they provide each other with advance information.
For workload reasons, controllers also may filter
communications (e.g., not hearing and responding to a pilot
readback while engaged in issuing clearances/instructions to
other aircraft or ensuring internal coordination).
To maintain situational awareness, this filtering process should
be adapted, according to the flight phase, for more effective
listening.
For example, when occupying an active runway (e.g., back-
taxiing or holding in position) or when conducting a final
approach to an assigned runway, the flight crew should listen
and give attention to communications related to the landing
runway.
Training Program
A company training program on pilot-controller
communication should involve flight crews and ATC
personnel in joint meetings, to discuss operational issues and,
in joint flight/ATC simulator sessions, to promote a mutual
understanding of each other’s working environment,
including:
• Modern flight decks (e.g., flight management system
reprogramming) and ATC equipment (e.g., absence of
primary returns, such as weather, on modern radar
displays);
• Operational requirements (e.g., aircraft deceleration
characteristics, performance, limitations); and,
• Procedures (e.g., standard operating procedures [SOPs])
and instructions (e.g., CRM).
Special emphasis should be placed on pilot-controller
communication and task management during emergency
situations.
Per quanto riguarda l'ultimo quote qui sopra, un paio di mesi fa ho avuto il piacere di ospitare un giovane controllore dell'ACC di Milano in flight deck e dalla cordiale chiacchierata e' emerso che era la prima volta che sedeva in un cockpit e che conseguentemente non aveva mai visto come funziona e cosa si vede su un radar meteo ne' tantomeno sul TCAS per non parlare della sua curiosita' nell'apprendere per la prima volta cosa fosse lo "sterile cockpit" o che in alcuni aeroporti ogni compagnia/aereo avessero specifiche procedure di volo in caso di piantata motore......
