Huge carriers, specifically, will regularly have such lighting on the trailing edge of each wingtip. These lights are additionally some of the time put along the trailing edges of the horizontal tail. Another famous area is...

Aircraft Electrical Power •Batteries installation and operation •Electronics emergency equipment requirements •Cabin entertainment equipment  Batteries installation and operation Location Requirements Accessibility for Battery Maintenance and Removal  Protection from Engine Heat Protection from Mechanical damage Passenger Protection Air frame Protection  1. Accessibility for Battery Maintenance and Removal - Install and locate the battery so that it can be readily removed and re-installed.  The electrolyte level of the battery  needs frequent checking. 2. Protection from Engine Heat - The installation should protect the battery from extreme engine heat, which would be detrimental to the battery's service life and reliability. When locating the battery within the engine compartment, choose a location that will not interfere with the flow of engine cooling air. 3. Protection from Mechanical damage - Vibration and other shock lo...

Aircraft Electrical Power A.C Power generation  D.C Power generation Emergency Power generation Voltage Regulation Power distribution  Inverters  Transformers A.C Power generation Alternating current (ac) generators supply the electrical energy for operating aircraft avionics  equipment. A generator is a machine that converts mechanical energy into electrical energy by electromagnetic induction. Alternating current (AC) electrical systems are found on most multi-engine, high performance turbine powered aircraft and transport category aircraft. AC is the same type of electricity used in industry and to power our homes. The AC power is typically a three-phase wye generator at 115VAC using 400Hz. Use of 400Hz power has been a standard for decades as the power can be produced with smaller and lighter generators than 50/60Hz systems . Although the use of higher frequencies is not ideal for long distance power transmission (more sensit...

General electronics/digital aircraft systems are -  ECAM (Electronic Centralized Aircraft Monitoring) EFIS (Electronic Flight Instrument System) EICAS (Engine Indicating & Crew Alerting System) FMS (Flight Management System)      ECAM (Electronic Centralized Aircraft Monitoring) An  electronic  centralized  aircraft monitor  (ECAM) is a system, developed by Airbus , that monitors aircraft functions and relays them to the pilots.  ECAM produces messages detailing failures and in certain cases, lists procedures to undertake to correct the problem. Airbus developed ECAM, such that it not only provided the features of (Engine Indicating and Crew Alerting System)EICAS, but also displayed corrective action to be taken by the pilot, as well as system limitations after the failures. Using a color-coded scheme the pilots can instantly assess the situation and decide on the actions to be taken. ECAM was  designed to...
