What are GPWS callouts?
GPWS callouts are aural alerts that are played through speakers in the cockpit to warn pilots about potential flight into terrain. The EGPWS Caution Callouts are: “Terrain Terrain”, “Too Low Terrain”, “Terrain Ahead”, “Obstacle Ahead”, Sink Rate, Sink Rate”, “Too Low – Gear”, “Too Low – Flaps”, and “Glide Slope”.
How do aircraft aural warnings work?
Aircraft aural warning systems work in conjunction with illuminated annunciator systems. They audibly inform the pilot of a situation requiring attention. Various tones and phrases sound in the cockpit to alert the crew when certain conditions exist.
What does TAWS stand for?
A Terrain Avoidance and Warning System (TAWS) is a safety net that automatically provides a distinctive warning to pilots when the their aeroplane is, based only on the radio altimeter reading and terrain closure rates derived therefrom, in potentially hazardous proximity to terrain.
What is the difference between GPWS and TAWS?
“The difference between an early GPWS system and a TAWS or EGPWS system is that we add the forward looking terrain awareness (FLTA) function, which uses a database to alert the pilot to hazardous terrain or obstructions that are ahead of the aircraft,” explained Gordon Pratt, vice president of business development for …
How should the pilot react to an engaged stall warning?
Buffeting or the activation of a stall warning system….At the first indication of an impending stall, the pilot should:
- Positively reduce the angle of attack.
- Level the wings.
- Retract speedbrakes if extended.
- Add power/thrust as recommended by the manufacturer.
- Recover to a safe attitude, speed and altitude.
What does dont sink mean?
“Don’t sink” is after take off to ensure that they keep on climbing immediately after take off. “Sink rate” is at any other time when the sink rate gets excessive.
What is GPWS in aviation?
The Ground Proximity Warning System (GPWS) generates advisory Alerts and mandatory response Warnings to the flight crew in respect of their proximity to terrain.

Are TAWS mandatory?
Information provided by TAWS In essence, Class A systems are required for all but the smallest commercial air transport aircraft, while Class B systems are required by larger General Aviation (GA) aircraft and recommended for smaller commercial or GA aircraft.
What is stalling in a plane?
When an aeroplane stalls, it is not like a car – the engine does not stop. The stall is a breakdown of the smooth airflow over the wing into a turbulent one, resulting in a decrease in lift. The lift will no longer fully support the aeroplane’s weight, and the aeroplane sinks.

What is glideslope warning?
When the crew is making an instrument landing system—ILS—approach, mode 5 announces “Glide slope” if the aircraft has deviated below a safe flight path to the runway. Another operating mode calls out altitudes during descent, and the last warns of significant wind shear.
What does bank angle mean?
The bank angle is the angle at which the vehicle is inclined about its longitudinal axis with respect to the horizontal.
What is the difference between TAWS and GPWS?
What is Class A TAWS?
Class A TAWS equipment must provide terrain information to be presented on a display system. Class A TAWS equipment must provide indications of imminent contact with the ground for the following conditions: Excessive Rates of Descent. Excessive Closure Rate to Terrain. Negative Climb Rate or Altitude Loss After Take- …
