If gpws ground proximity warning system activates and alerts pilot with an aural warning 'don't sink' twice times it because During take off or missed approach manoeuvre, aircraft has started to lose altitude, aircraft experiences an unexpected proximity to terrain, with landing gear retracted, at too low altitude, aircraft has an excessive rate of descent, aircraft experiences an unexpected proximity to terrain, without landing flap selected. Question Alerting Systems, Proximity Systems 60 Answer 19
An aircraft descending from fl 390 to ground level at maximum speed the limits in speed will be Initially mmo, then vmo below a certain flight level, initially vmo, then mmo below a certain flight level, mmo only, vmo only. at fl390, mach number your flight reference speed. at fl390, your are above crossover altitude. the crossosver altitude the altitude at which a specified cas mach value represent same tas value. mmo (maximum operating mach) will be your first limit, at crossover altitude, vmo (maximum operating speed) will then become limit. Question Alerting Systems, Proximity Systems 60 Answer 20
Considering an airspeed indicator a second stripped needle if installed indicates Maximum operating speed (vmo), never exceed speed (vne), never exceed speed (vne) or maximum operating speed (vmo), depending on which the lowest, never exceed speed (vne) or maximum operating speed (vmo), depending on which the higher.

Your aircraft tcas ii equipped to be able to generate a traffic advisory ta intruder must be at least equipped with A transponder mode a, a tcas ii, a transponder mode c, a transponder mode s. Question Alerting Systems, Proximity Systems 60 Answer 37
Your aircraft tcas ii equipped an intruding traffic only has a mode a transponder the information available to your tcas equipment Two dimensional onlyyour tcas cannot generate ras (resolution advisories), two dimensional onlyyour tcas cannot generate tas (traffic advisories), three dimensionalyour tcas can generate both tas (traffic advisories) ras (resolution advisories), three dimensionalyour tcas cannot generate tas (traffic advisories). Question Alerting Systems, Proximity Systems 60 Answer 38
Your aircraft tcas ii equipped to be able to generate a resolution advisory ra intruder must be at least equipped with A transponder mode c, a tcas ii, a transponder mode a, a transponder mode s. for aircraft to be visible to a tcas equipped aircraft they must have a minimum of a mode 'a' transponder. if transponder switched off, or unserviceable, intruding aircraft are invisible to tcas equipment a collision risk exists. mode 'a' transponders transmit no height information therefore information available to tcas equipment two dimensional only therefore can only give tas. mode 'c' transponder equipped intruders broadcast height information to tcas equipment the system becomes three dimensional can now give both tas ras.
