What systems protect against a stall?

What systems protect against a stall?

Stall warning, stick shaker, stick pusher, etc...

Generically we can destinguish between systems that alert the pilot of the impeding stall, like stall the stall warning or stick shaker, and systems that try to correct the situation, like a stick pusher.

What are the effects on the human body in case of depressurisation?

What are the effects on the human body in case of depressurisation?

Hypoxia, a lack of oxygen to tissues of the body due to low partial pressure at altitude.

Symptoms are: blue lips, apparent personality change, impaired judgement, muscular impairment, short term memory loss, sensory loss, hyperventilation, unconsciousness.

Other possible effects:

  • Baurotrauma

  • Lung damage

How would you load an aircraft for max range?

How would you load an aircraft for max range?

The position of the CG directly influences the fuel consumption of an aircraft. An aft position of the CG makes the aircraft less stable, requiring less lift to be generated in both the horizontal stabilizer and wings, reducing the overall drag of the aircraft, and increasing the max range.

You want to load the the aircraft so that the CG is at, or as close as possible, to the aft limit (Without exceeding it).

What pressure does a pitot tube measure?

What pressure does a pitot tube measure?

The total pressure (static and dynamic pressure).

What is induced drag?

What is induced drag?

Induced drag and its wing tip vortices are a direct consequence of the creation of lift by the wing.

Since the Coefficient of Lift is large when the Angle of Attack is large, induced drag is inversely proportional to the square of the speed whereas all other drag is directly proportional to the square of the speed.

The effect of this is that induced drag is relatively unimportant at high speed in the cruise and descent where it probably represents less than 10% of total drag. In the climb, it is more important representing at least 20% of total drag. At slow speeds just after take off and in the initial climb, it is of maximum importance and may produce as much as 70% of total drag.

Finally, when looking at the potential strength of wing tip vortices, all this theory on induced drag must be moderated by the effect of aircraft weight. Induced drag will always increase with aircraft weight.

How does an altimeter work and which errors can an altimeter experience?

How does an altimeter work and which errors can an altimeter experience?

When an aircraft climbs, the static pressure in the instrument case decreases, which allows the enclosed capsule to expand.

This in turn moves the needle on the instrument to indicate a corresponding altitude.

During descent, the opposite function applies.

Altimeter errors can originate and vary from:

Instrument Pressure Time-lag Barometric Density Temperature Blocked static port

The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?

The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?

The Boeing 737 has an all moving horizontal stabilizer.

Do single engined planes have a VMCG?

Do single engined planes have a VMCG?

No, VMCG is defined as the minimum control speed on the ground, with one engine inoperative (critical engine on two engine airplanes), takeoff power on other engine(s), using aerodynamic controls only for directional control and thus only applicable to ME aircraft.

Why does a wing stall?

Why does a wing stall?

A wing stalls because the airflow over the wing’s upper surface separates when the critical angle of attack is reached or exceeded. This causes a reduction in the lift generated by the aerofoil

What are the advantages of operating a one aircraft type fleet, why don’t we use an A320 / B737 mixed fleet?
