It is the ratio of the weight of a given volume of material to the same volume of water

The specific gravity of electrolyte on a lead acid

It is used to test specific gravity by measuring the depth of a float sink in a sample of electrolyte

True or FALSE: Temperature of electrolyte effect specific gravity, it is more dense as the temperature increase.

Consider 12 cell lead acid battery. Find the internal resistance of a battery if it delivers 10 amperes to a load that is having a resistance of 1 ohms.

It is the most effective way to charge a battery

It is defined as the performance of tasks required to ensure the continuing airworthiness of an aircraft.

Its primary purpose is to monitor the progress of wear out processes.

It generally consists of a general inspection of the interior/exterior of the airplane with selected areas opened.

It is typically scheduled every 12- 20 months depending on the operator, airplane type and utilization.

A type of maintenance check that is also known as Heavy Maintenance Check.

The status of an aircraft, engine, propeller or part when it conforms to its approved design and is in a condition for safe operation.

It is define as any instrument, mechanism, equipment, part, apparatus, appurtenance, or accessory, including communications equipment, that is used or intended to be used in operating or controlling an aircraft in flight, is installed in or attached to the aircraft and is not part of an airframe, engine or propeller.

Define as making precise measurements and adjustments to equipment or systems in order to obtain optimum performance and to certify that output data falls within prescribed tolerances.

Which of the following statement defines Minor Modification?

An organized examination or formal evaluation exercise. In engineering activities inspection involves the measurements, tests, and gauges applied to certain characteristics in regard to an object or activity.

Checking an item of equipment for cleanliness, need for lubrication, or painting and deterioration of parts or materials.

An intensive examination of a specific item, installation or assembly to detect damage, failure or irregularity.

An examination of a specific item, installation, or assembly making use of specialized inspection techniques such as Non Destructive Testing (NDT)

An "in motion" or "power on" test for determining that an item of equipment will operate at a specified performance level.

It evaluates only a single system within the entire aircraft.

A document used by manufacturers of aircraft, their engines or their components to communicate details of modifications which can be embodied in aircraft.

It contain mandatory instructions to carry out work on aircraft, engine, propeller or component in order to address an unsafe condition which exists, or is likely to exist, or could develop.

It is understood as “any maintenance that is carried out before flight to ensure that the aircraft is fit for the intended flight.”

It is referred as Heavy (or Depth) Maintenance, and consists of tasks that are generally more in-depth and long-lasting, but are performed less frequently.

It is performed even when machines or the systems are in complete functional mode, to avoid any breakdowns or issues from occurring in the future.
