Aeronautical Technologies for the Twenty-First Century

Stability is provided by the flight control system. Fuel consumption improvements on the order of 5 percent are expected for conventional subsonic transports. The additional flexibility in center-of-gravity location and even greater fuel burn reduction are particularly important to tailless flying wing designs, allowing the use of more wing volume. Relaxed static stability will also

Early warning and prediction of flight parameter abnormalities

Failure to understand, in an early stage, the implications of certain system failures on the capability of other aircraft systems has been cited as a contributing factor in several accidents [8], [12].However, current automated flight monitoring systems do not alert the flight crew of a failure until a parameter value has exceeded an alert limit.

6 FAQs about [Battery and flight control system abnormalities]

What is aircraft battery inspection?

Aircraft battery inspection consists of the following items: Inspect battery sump jar and lines for condition and security. Inspect battery terminals and quickly disconnect plugs and pins for evidence of corrosion, pitting, arcing, and burns. Clean as required. Inspect battery drain and vent lines for restriction, deterioration, and security.

Can I add electrolyte to my aircraft battery?

Do not add electrolyte. Battery state of charge is determined by the cumulative effect of charging and discharging the battery. In a normal electrical charging system, the aircraft generator or alternator restores a battery to full charge during a flight of 1 hour to 90 minutes.

Do airplanes have a battery ventilating system?

Modern airplanes are equipped with battery ventilating systems. The ventilating system removes gasses and acid fumes from the battery in order to reduce fire hazards and to eliminate damage to airframe parts. Air is carried from a scoop outside the airplane through a vent tube to the interior of the battery case.

How do airplane batteries work?

Air is carried from a scoop outside the airplane through a vent tube to the interior of the battery case. After passing over the top of the battery, air, battery gasses, and acid fumes are carried through another tube to the battery sump. This sump is a glass or plastic jar of at least one pint capacity.

What should I do when installing batteries in an aircraft?

Installing batteries—When installing batteries in an aircraft, exercise care to prevent inadvertent shorting of the battery terminals. Serious damage to the aircraft structure (frame, skin and other subsystems, avionics, wire, fuel, etc.) can be sustained by the resultant high discharge of electrical energy.
