Qual é o objetivo da função MSAW?
Minimum Safe Altitude Warning (MSAW) is a ground-based safety net intended to warn the air traffic controller (ATCO) about the increased risk of controlled flight into terrain by generating, in a timely manner, an alert of aircraft proximity to terrain or obstacles.
The main purpose of MSAW is to enhance safety and not to monitor adherence to any specified minima. In practice MSAW is a part of the ATC system and from this perspective it can be regarded as a “function”.

Em que circunstâncias deverá uma aeronave ser informada da sua posição?
a) upon identification, except when the identification is established:
i) based on the pilot’s report of the aircraft position or within one nautical mile of the runway upon departure and the observed position on the situation display is consistent with the aircraft’s time of departure; or
ii) by use of ADS-B aircraft identification, Mode S aircraft identification or assigned discrete SSR codes and the location of the observed position indication is consistent with the current flight plan of the aircraft; or
iii) bytransferofidentification;
b) when the pilot requests this information;
c) when a pilot’s estimate differs significantly from the controller’s estimate based on the observed position;
d) when the pilot is instructed to resume own navigation after vectoring if the current instructions had diverted the aircraft from a previously assigned route (see 8.6.5.5);
e) immediately before termination of ATS surveillance service, if the aircraft is observed to deviate from its intended route.
