The Auxiliary Power Unit (APU) in the Boeing 787-9 Dreamliner serves several important purposes, primarily when the aircraft is on the ground or in specific flight conditions. Here’s a breakdown of its functions: 1. Electrical Power Generation: • The APU on the 787 is primarily used to supply electrical power to the aircraft systems when the main engines are not running. Unlike traditional aircraft APUs, which also provide pneumatic power for starting engines or air conditioning, the 787 relies on an all-electric architecture. • The APU provides power to the aircraft systems during ground operations, such as preflight checks, cabin lighting, avionics, and air conditioning. 2. Engine Start: • The APU provides the electrical power needed to start the main engines. This eliminates the need for external ground power sources in most scenarios. 3. Backup Power: • The APU can act as a secondary source of electrical power if an in-flight emergency or failure of the main generators occurs, ensuring essential systems remain operational. 4. Cabin Comfort and Systems: • The APU supports air conditioning systems on the ground, ensuring passenger comfort during boarding and pre-departure. 5. Flexibility for Remote Operations: • In remote locations without access to external ground power or air conditioning units, the APU allows the aircraft to operate independently. The 787’s APU is unique in its design, as it aligns with the aircraft’s highly electric architecture, reducing reliance on traditional pneumatic systems and improving overall efficiency… #a#airlinepilotf#fl360aero#indiap#philippinesp#pakistaniu#usad#dubai#f#fyp#aviationphotographyp#pilota#aviaviationa#aviationphotographya#aviationdailyation#airbusloversa#airbus000 #a#a321f#flightsimulator #a#aviation4ua#aviationphotoi#ivaoa#aviationa#aviationdailya#aviationloversa#aviationgeeka#aviation4ua#aviationworlda#aviationpicsa#aviationspottera#aviationlifea#aviationforevera#aviationeverywherea#aviationenthusiasti#instaaviationi#instagramaviationa#aviationindustrya#aviationismylife#aviationenthusiastsc#cockpitf#flightdecka#airbusa#aa#aviationb#boeinga#avgeeka#aviationloversp#planespottinga#aviationphotographya#airplanea#airbusaa#aircrafta#airporta#aviationphotographya#airplanea#airbusaa#aircrafta#airporta#airbusloversp#planea#aviationdailyp#piloti#instagramaviationa#airbusaa#aircrafta#airporta#airbusloversp#planea#aviationdailyp#piloti#instagramaviationa#aviationgeeki#instaaviationl#loversp#planespotteri#instaplaneb#bf#flightn#neou#up#pilotlifet#travels#spottingp#planespottera#aviationL#Lifestylea#antonovc#cargav#viralm#mechanicp#pilotlifea#airbusloversa#airbusa#a321f#flightsimulatora#aviationa#aviationphotographya#aviationdailya#aviation4ua#aviationphotoi#ivaoa#aviationa#aviationdailya#aviationenthusiasti#instaaviationa#aviationloversa#aviationgeeka#aviation4ua#aviationworlda#aviationpicsa#aviationspottera#aviationlifea#aviationforevera#aviationevervwhereRAFTENGIN#i#instagramaviationa#aviationindustrya#aviationismylifeviationenthusiasts #c#cockpitf#flightdecka#airlinew#worklifet#travelourself #a#airlinet#travelw#worklifet#travelourself #a#airlinet#traveli#inflight#worklifef#flightfacts#aircraftengineera#aviationa#airline
