What is a stall warning system?

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.

When should the pilot be alert to the possibility of an accelerated stall?

The flight instructor should be aware that during traffic pattern operations, any conditions that result in overshooting the turn from base leg to final approach, dramatically increases the possibility of an unintentional accelerated stall while the airplane is in a cross-control condition. Figure 4-8.

What is a non electric stall warning device How does it work?

There is no electricity involved. The “lift detector” stall warning horn uses a tab that can be lifted during the preflight walk-around to sound the stall horn and requires an electrical system to operate. The lift detector does not react during normal airflow over the wing.

What happens when plane stalls?

When an airplane stalls, it’s no longer able to produce lift. When this occurs, there’s an insufficient amount of air traveling under the airplane’s wings to keep it up. As a result, the airplane will drop, thereby reducing its altitude, until the angle of attack is correctly adjusted.

What is a stall warning system in aviation?

Stalls. Stalls can happen at any airspeed, but only one angle of attack, the critical angle of attack. The wing’s angle of attack is the critical factor in determining how close the aircraft is to an aerodynamic stall. Therefore, an angle-of-attack (AoA) sensor is the ultimate stall warning and protection system.

When would an accelerated stall occur?

An accelerated stall is typically demonstrated during steep turns of about 45 degrees bank and in the cruise configuration, i.e., gear and flaps up. As with all stalls, begin the demonstration below the airplane’s published maneuvering speed (VA) adjusted for weight.

Why do we need pre-flight inspection?

As the pilot in command you are responsible to ascertain that the aircraft is an airworthy condition. As such you are required to check all papers as weight (mass) and balance, logbooks, licenses and limitations. And part of any flight is a thorough visual inspection of the airplane.

How does Airplane detect stall?

Aircraft can stall at any airspeed, the only real indicator for a stall is an angle of attack indicator. This is because weight, icing, flaps, G-forces being pulled, and speed all effect the aircraft’s stall speed.
