The elevation of the departure area
Under what condition will true altitude be lower than indicated altitude?

(Refer to Figure 3.) Altimeter 3 indicates

9,500 ft
Under what condition is indicated altitude the same as true altitude?
When at sea level under standard conditions
(Refer to Figure 7.) The proper adjustment to make on the attitude indicator during level flight is to align the
