Sensors & Antennae
On the nose are three air speed sensors: the port and starboard pitot heads for the instruments, and the central “Q-Pot” head for the speed-sensitive powered controls.
On top of the fuselage there are long HF (high-frequency) antennae. These varied from operator to operator, and especially with the RAF. This arrangement was common to the majority of civil airlines.
Under the wing are boomerang-shaped VHF horns, and long ADF (direction-finding) antennas. The illustration also shows the nacelle NACA ducts, compressor seal and engine bay cooling outlets (long tubes).
Small white shark-fins in front of the split flaps are
crash levers. On a real Comet, if they hit the ground,
the fire extinguishers would be set off, and the main
battery supply and fuel supply to the engines would be
severed.
