-
A
It reduces errors caused by the transition from instrument to visual flight, decreases the minimas for both take-off and landing, and reduces the risk of aircraft upsets.
-
B
It reduces cockpit space, thus aircraft weight.
-
C
The HUD is an advanced system enabling the automatic response to TCAS RAs.
-
D
It is very compact.
Refer to figure.
HEAD-UP DISPLAYS (HUD)
Head-up displays are transparent screens that show a simplified monochromatic primary flight display information possibly with some essential navigation information in the direct view of the pilot, who can look out of the window and see flight data at the same time.
The HUD replicates the information on the primary flight display (PFD) by showing the following data: altitude; speed, including speed trend; heading; flight path vector (track and vertical flight path); flight mode annunciator (FMA); CAS, TAWS and wind shear command annunciations.
Some benefits of having an HUD include:
- Increased situational awareness due to reduced need to look inside to view primary flight information;
- Lower minima for both departure and landing;
- Improved accuracy of flying thus reduced susceptibility to enter a state of aircraft upset.
