When landing, what exactly do the phrases "approaching minimums" and "minimums" mean in a commercial jet aircraft, when heard from the onboard cockpit voice.
The "Approaching Minimums" callout is made by the Pilot Monitoring (or, in some cases equipment, the GPWS -- Ground Proximity Warning System) as the aircraft is descending on an instrument approach and has reached an altitude 100 feet above the minimums for that approach -- the Decision Altitude (DA -- typically used for a Cat I ILS, and set as XXX' MSL) or Decision Height (DH -- typically used for a Cat II or Cat III ILS and set as XXX' or XX' on the Radio Altimeter) or Minimum Descent Altitude (MDA -- typically used for a nonprecision approach and set as XXX' MSL). The response by the Pilot Flying is usually standardized and indicates he is looking outside in order to acquire the visual references he'll need to land.
The "Minimums" callout is made at the minimum altitude, and this is the point that the Pilot Flying has to make a decision -- continue or go around. His response at this point is again standardized so that the other pilot is entirely clear on the course of action. His response is usually something like "Landing" or "Continue", or else "Go Around." Often, the autopilot comes off at this point as well & you hear the horn indicating such on the CVR as well.
"Approaching Minimums" you are about at your minimum descent altitude (MDA) or decision altitude (DA).
"Minimums" means you've arrived at that altitude.
Pilots use those phrases to alert the pilot flying when they're getting close to the ground. At minimums they will either have the runway environment in sight and decide to continue and land on the runway or they will not have the runway environment in sight and decide to go around.
Approaching minimums is the decision making altitude or minimum altitude ( Generally 100 feet above the minimum altitude ). Captain callout ‘approaching minimums’ in order to decide that they will land on the runway or they will go around, that depends on the Captain. In their final approach if they are going for landing then the other pilot callout “ continue” or else the other pilot callout “Goaround” and then the landing was aborted....the Pilot pushes the thrust levers to its maximum position in order to get the maximum thrust generated by the engines and then the landing gear was retracted in order to goaround....
