What is a flight warning system?

Having both a visual and an audio form, the Flight Warning Systems (FWS) allows the crew: to recognise a state of failure or a dangerous configuration. to unambiguously identify the component failure or faulty configuration. to indicate the corrective actions and procedures to restore normalcy.

How does aircraft warning system work?

The system monitors an aircraft’s height above ground as determined by a radar altimeter. A computer then keeps track of these readings, calculates trends, and will warn the flight crew with visual and audio messages if the aircraft is in certain defined flying configurations (“modes”).

How do stall warnings work?

Stall warning is provided by an electronic or mechanical device that sounds an audible warning as the stall speed is approached. The simplest such device is an airframe mounted stall warning horn which sounds when the airflow through it occurs at a specific angle.

What activates the takeoff warning system?

Activation. The Takeoff Configuration Warning System is, in most aircraft types, armed by one of: a single thrust lever position. the position of two or more thrust levers.

Why do planes say don’t sink?

Mode 3 helps pilots maintain a positive climb rate after takeoff; once the aircraft reaches 1,000 feet, the system sounds a “Don’t sink” warning if altitude begins to descend. Mode 4 warns if landing gear or flaps are not properly configured for landing, and if the terrain clearance is inadequate during final descent.

What are the different types of Egpws mode?

Several modes are included in a basic GPWS system:

  • Mode 1 – High rate of descent.
  • Mode 2 – High rate of closure with the ground.
  • Mode 3 – Loss of altitude after take-off.
  • Mode 4 – Proximity to the ground when not in the landing configuration.
  • Mode 5 – Descent below the Instrument Landing System (ILS) glideslope.

What is Mach warning system?

Definition. A machmeter is an instrument which provides an indication of the Mach Number, (M), which is the ratio between the aircraft true air speed (TAS) and the local speed of sound (LSS).

Is stall warning required?

Re: Stall Warning System Required for Flight? There is no “legal requirement” for a stall horn.

How do I check my stall warning?

The lift detector system is easy to check during preflight. Turn on the Master switch, lift the tab, and the stall horn should sound. If you have just a hole in the wing that uses suction to blow a plastic reed, you’ll need to cover the hole with something first before drawing air out of the system with your mouth.

What is a train operated warning system?

The Automatic Warning System (AWS) was introduced in the 1950s in the United Kingdom to provide a train driver with an audible warning and visual reminder that they were approaching a distant signal at caution.

What is windshear warning?

Windshear is a drastic, sudden change in wind direction or speed over a relatively short distance in the atmosphere. When windshear is predicted or when the aircraft has encountered windshear, the system alerts the pilot and warns of danger.

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.

Do you need to plan a flight around a warning area?

You don’t need to plan an IFR flight around a MOA (unless you know they will always route you around it). With a Warning Area, though, it is your responsibility to check the times, and when needed, plan a flight around it. ATC will not vector you through a Warning Area if it’s hot or give you the altitude you want.

What does it mean to be in a warning area?

The AIM defines warning areas as: “Airspace of defined dimensions, extending from 3 NM outward from the coast of the US, that contains activity that may be hazardous to nonparticipating aircraft.” Okay, great, but what does that actually mean?

When to stay out of the warning area?

Stay out of the Warning Area unless you are positive it’s “cold” or has no activity the altitude you need. Luckily most small GA aircraft don’t venture farther than 3NM from the coast because it’s out of their glide range. But IFR multi-engine pilots at higher altitudes need to be careful!

How does the takeoff configuration warning system work?

When the arming condition(s) have been met, sensors on the monitored systems will provide position or status information to the Takeoff Configuration Warning System and an alarm will be generated if a monitored component is not in an approved takeoff configuration. Accident and Serious Incident Reports Involving Improper Takeoff Configuration
