FPV, seeing from the air

1.[2p]

The FPV video chain is optimised above all for

Correct
The answer is: low latency, because a delayed view means the pilot reacts to where the craft was
The answer is: low latency, because a delayed view means the pilot reacts to where the craft was
The answer is: low latency, because a delayed view means the pilot reacts to where the craft was

2.[2p]

Analog FPV video survives near the edge of range better than digital because

Correct
The answer is: it fails gracefully, getting grainy but staying readable, rather than freezing at a cliff
The answer is: it fails gracefully, getting grainy but staying readable, rather than freezing at a cliff
The answer is: it fails gracefully, getting grainy but staying readable, rather than freezing at a cliff

Running the highest possible VTX power is always the best choice.

The answer is: False
Correct

4.[2p]

Two craft flying on the same 5.8 GHz video channel will

Correct
The answer is: interfere so that both pilots see static, which is fixed by spacing their channels apart
The answer is: interfere so that both pilots see static, which is fixed by spacing their channels apart
The answer is: interfere so that both pilots see static, which is fixed by spacing their channels apart

5.[3p]

FPV links use circularly polarised antennas mainly because

Correct
The answer is: they keep a steady signal as the craft rolls and flips, and reject ground-bounced reflections
The answer is: they keep a steady signal as the craft rolls and flips, and reject ground-bounced reflections
The answer is: they keep a steady signal as the craft rolls and flips, and reject ground-bounced reflections

An FPV camera prioritises wide dynamic range so that

Correct
The answer is: a pilot bursting from shadow into bright sunlight is not blinded while the craft is still moving
The answer is: a pilot bursting from shadow into bright sunlight is not blinded while the craft is still moving
The answer is: a pilot bursting from shadow into bright sunlight is not blinded while the craft is still moving

Glass to glass latency is

Correct
The answer is: the total delay from the camera lens to the goggle screen, which adds to the pilot's reaction time
The answer is: the total delay from the camera lens to the goggle screen, which adds to the pilot's reaction time
