That is the sensor for the aircraft's Enhanced Vision System (EVS) - a combination of a visible low light and infra red video cameras which are combined together via computer into a composite image for display on either the PFDs or HUD in the cockpit. It provides better situational awareness in poor visibility and during night operations for the crew. See ...

There is a good writeup here that explains the engine issues as well as the rest of the incident you mentioned. Core lock happens when parts inside the engine cool off at different rates, causing interference between them. In the case of the CF34 engines on these Bombardier jets: GE isolated the problem to contact between components of the high-pressure-...

The fan section of a turbofan engine is driven by the low pressure (LP) spool. This means that it is connected to two parts of the engine: The LP compressor, which must compress the air before it enters the high pressure (HP) compressor The LP turbine, which must receive the air after it exits the HP turbine The problem is that the HP section is efficient ...

My experience shows that, on some short haul domestic type operations, some pilots practice shutting down the left wing-mounted engine quickly after landing to be sure the engine has stopped turning to allow passengers to disembark down the steps. The quick turnaround operation may mean another engine start within 30 minutes of shut down. The core (heavy ...

These covers are used to keep foreign objects away and out of the air data sensors, pitot tubes, static ports and Angle of Attack sensors (large red covers) while the aircraft is resting on the ground. Blockage or damage to these sensors by foreign objects prevents the aircraft flight control computers and instruments from collecting accurate data and could ...

You can find manuals for many aircraft including the Challenger 300 at Smartcockpit. The Automatic Flight Control System section includes the function of the XFR button. There are two flight guidance computer cards that drive the autopilot, including the flight director and yaw damper. The XFR button switches how the computers are used. For most of the ...

As wikipedia mentions, "Electro-Hydrostatic actuators" (EHA) are self contained, the only input they need is electrical power and commands. The electricity powers up the hydraulic pump that is used to move the actuator piston, while the electrical commands are used to select what the actuator does through the use of a valve. What does electrically ...

It's important to understand that Bombardier Transportation/Aerospace, while ostensibly a company separate from the original Bombardier family (which only retained a minority stake when it was split off from Consumer Products - snowmobiles, watercraft, etc), is still actually controlled by the family due to a bizarre dual class share structure where the ...

The reason they are selling aircraft manufacturing lines to improve profit margin is because their aircraft business has a relatively low-profit margin. One of Bombardier most successful products is this: Bombardier Zefiro. Source: Bombardier It looks somewhat like an aircraft but it is missing the wings. It is called a "train". Bombardier calls itself "...

It is a mechanical checklist where each item on the list can be flipped to indicate that is has been checked. You can see it in operation in this YouTube video (which I believe is where you got the image from). Each of the 6 stacks can be extended to check the items and then collapsed again in order to not obstruct the pilot's view. It is not a default part ...

Bombardier offers these manuals through their Technical Publications department. For your purposes, the following product may suit your needs: Ground Handling, Servicing and Emergency Information Booklets These booklets are designed to provide information to personnel that are not necessarily familiar with BBAS aircraft, but are called upon to ...
