Airbus Certification and Regulation Evolution
Join me for a weekend read! ๐โ๏ธ
The different Airbus types have been certified at different times and comply with different certification rules.
๐ซ๐งต
A major change occurred when the FAA published an amendment to FAR Part 25, known as "๐๐ฆ๐๐ง๐๐ฆ๐๐ง๐ญ ๐๐-๐๐".
This amendment, which became effective on March 1, 1978, revised the takeoff performance standards and made them more restrictive.
Optimize Suite for Aircraft Performance
Performance varies over the life of all in-service aircraft, leading to slightly higher fuel consumption levels as an aircraft ages and leading to inconsistencies with the FMS trajectory prediction.
Mini ๐งตon Optimize Suite
#A320
Flight Management System (FMS) provides navigation for guidance, calculates fuel & trajectories for the flight based on numerous parameters, including terrain, runway location & airspace.
Airbus pioneered the FMS, which was integrated during the early 1980s on the first #A300โs.
In testing, New APU flap intake for #A320
Old position below fuselage is prone to oil leaks, external pollution i.e de-icing/hydraulic fluid/fluid from drain mast being reingested causing poor cabin air quality
Relocating intake saves 85% of related maintenance

The click when engaging AP on #A320
When the autopilot is engaged a solenoid operated detent locks both sidesticks in neutral position. If๐จโโ๏ธapplies a force above threshold (5daN in pitch, 3.5 daN in roll) AP disengages, stick is unlocked & the deflection is sent to the computers
A safety innovation by Airbus introduced on A300 is the inhibition of slat retraction if angle of attack is high or speed is low, called - Alpha Lock.
On the #A320, alpha lock occurs if the angle of attack exceeds 8.5 degrees or the speed is at or below 148 knots.
Now offered on #A350, latest gen of Electro-Dimmable Window (EDW) darken twice as fast & becomes 100 times darker than original version
They effectively block more than 99.999% visible light as well as infra-red energy (helps to keep cabin cooler & reduce load on air-con system)
