Instrument Question

Asked by: 1847 views Aircraft Systems


I am working on my instrument right now, and there is a question in my written study guide that states "Q: Altimeter setting is the value to which the scale of pressure altimeter is set so the altimeter indicates...." and I know the answer is "true altitude at field elevation".

My problem is the question makes absolutely no sense to me. Could someone please help me understand this?

    Not very well worded, is it?

    The “scale of pressure altimeter” is the “Kollsman window.” Replace one with the other and the question should make sense.

    Sounds to me like an attempt to make the question more generic on the theory that your pressure altimeter has some scale to set other than a “Kollsman window.”

    theory that your pressure altimeter has some scale to set other than a “Kollsman window.”

    Come to think of it, they do. A glass panel altimeter (G1000, Avidyne, Aspen Avionics, etc) has a “scale of pressure” to set for the altimeter but it is definitely not a “Kollsman Window”.
