How far off can your altimeter be?
The minimum safe altitude of a route is 19,000 feet MSL and the altimeter setting is reported between 29.92 and 29.43 “Hg, the lowest usable flight level will be 195, which is the flight level equivalent of 19,500 feet MSL (minimum altitude (TBL ENR 1.7-1) plus 500 feet).
What is Airport altimeter setting?
Altimeter setting is the value of the atmospheric pressure used to adjust the sub-scale of a pressure altimeter so that it indicates the height of an aircraft above a known reference surface.
What are the standard altimeter settings?
The standard altimeter 29.92 inches Mercury (“Hg.) setting at the higher altitudes eliminates station barometer errors, some altimeter instrument errors, and errors caused by altimeter settings derived from different geographical sources.
Are altimeters accurate?
Digital altimeters are extremely precise (often offering one-foot precision in their display, and 0.01 inches of mercury for the pressure setting).

How accurate are handheld altimeters?
Accuracy is generally within a couple of percent, especially if you’re selecting among some of the better altimeters on the market. But you can get pin-point accuracy if you’re willing to pay for it.
Is 29.92 a high barometric pressure?
A barometer value above 29.92”Hg is a high pressure system and usually means air is cooling, humidity is decreasing, and the pressure of that air is stabilizing the atmosphere. A barometer reading below 29.92”Hg is a low pressure system and usually means air is warming and humidity is increasing.
What altitude is RVSM airspace?
2,000 feet
Within airspace where RVSM procedures are suspended, the vertical separation minimum between all aircraft will be 2,000 feet above FL290.
