Used to drive aircraft systems when main engines are shut down.

Performed flight tests of the most advanced aircraft systems in the world.

Today, at least in some aircraft systems, the annunciation voice may be either male or female.

Aircraft system safety requires the independence of failure conditions for multiple systems.

The military role of unmanned aircraft systems is growing at unprecedented rates.

It is the first university to offer a degree in unmanned aircraft systems operations.

The aircraft system and the ground control station were carried in separate backpacks.

Its sole purpose was to investigate the effect of radiation on aircraft systems.

The recorder could provide information about speed, altitude, engine activity and other aircraft systems.

The signals cell phones and other devices give off might effect critical aircraft systems over time.

Other advanced courses cover specific aircraft systems and provide troubleshooting skills.

All the aircraft systems were in the green.

This is because the aircraft systems differ so widely.

There was sufficient fuel on board and nothing was wrong with the aircraft systems.

Its facilities include aircraft systems and structural test labs.

But figuring out what is wrong with a complex aircraft system is far more complicated, he added.

The guide was revised several times and became a muli-volume set divided by aircraft systems.

Candidates must pass tests and be trained in the Douglas Aircraft system.

Many modern aircraft systems are digital or digitally controlled.

Certain aircraft systems may or may not be simulated.

The training rounds even returned the correct indications to the carrying aircraft systems if they were 'armed' in flight.

This consortium was established to create a European common technical standard for aircraft systems and a centralized purchasing office.

Under these rules, relevant aircraft systems must be fully simulated, and a comprehensive aerodynamic model is required.

Ground School (aircraft systems, local course rules, emergency procedures)

This may cause a structural failure, or, if not, can be sufficient for defeating the redundancy of aircraft systems.
