Question

An aeroplane flew from the Langley airport with a altimeter setting of 29.82 in Hg to the Victoria Harbour water aerodrome at sea level and the altimeter indicates 100 feet.

The correct altimeter setting for Victoria Harbour is

Answer 1

The correct altimeter setting for Victoria Harbour would likely be around 29.92 in Hg.

Step-by-step explanation:

The altimeter setting is crucial for accurate altitude readings, as it calibrates the altimeter to the local atmospheric pressure. The airplane flew from Langley, where the altimeter setting was 29.82 in Hg, to Victoria Harbour at sea level, where the altimeter read 100 feet. The altimeter setting needed for accurate readings is typically 29.92 in Hg at sea level.

When an altimeter reads 100 feet at sea level with an altimeter setting of 29.82 in Hg, it suggests that the altimeter setting is lower than the standard setting of 29.92 in Hg. This discrepancy causes the altimeter to indicate a lower altitude than actual. To correct this, the altimeter setting should be increased to 29.92 in Hg, which is the standard pressure at sea level under normal atmospheric conditions.

Therefore, to ensure the altimeter accurately reflects the altitude at Victoria Harbour, the correct altimeter setting would likely be around 29.92 in Hg. Adjusting the altimeter setting to this standard value would align it with the local atmospheric pressure at sea level, providing accurate altitude readings for the aircraft operating in that area.
