- Chapter 8: Flight Instruments › Altimeter Operation
altimeter indicates an altitude above the actual field elevation. If the barometric pressure setting is reset to the current altimeter setting of 29.68 "Hg, then the field elevation is again indicated on the altimeter. This pressure change ... easily noticed in flight since aircraft fly at specific altitudes. The aircraft steadily decreases true altitude while the altimeter is held constant through pilot action as discussed in the previous section. Knowing the aircraft’s altitude is vitally important…
- Chapter 7: Helicopter Performance › Performance Charts › The Effect of Weight Versus Density Altitude
Effect of Weight Versus Density Altitude The height/velocity diagram [Figure 7-1] depicts altitude and airspeed situations from which a successful autorotation can be made. The time required, and therefore, altitude necessary to attain a steady state autorotative descent ... dependent on the weight of the helicopter and the density altitude. For this reason, the H/V diagram is valid only when the helicopter is operated in accordance with the gross weight versus density altitude chart. If published, this chart…
- Chapter 8: Flight Instruments › Types of Altitude
Indicated altitude—read directly from the altimeter (uncorrected) when it is set to the current altimeter setting. 2. True altitude—the vertical distance of the aircraft above sea level—the actual altitude. It is often expressed as feet above mean ... level (MSL). Airport, terrain, and obstacle elevations on aeronautical charts are true altitudes. 3. Absolute altitude—the vertical distance of an aircraft above the terrain, or above ground level (AGL). 4. Pressure altitude—the altitude indicated when the altimeter setting…
- Chapter 9: Basic Flight Maneuvers › Common Errors › S-Turns
Common Errors 1. Faulty entry technique. 2. Poor planning, orientation, and/or division of attention. 3. Uncoordinated flight control application. 4. Improper correction for wind drift. 5. Failure to maintain selected altitude and airspeed. 6. Selection of a ground reference with ... size on opposite sides of the reference line. [Figure 9-16] The maneuver should be performed at a constant altitude between 500 and 800 feet above the terrain. As mentioned previously, if the student pilot is having a difficult time…
- Chapter 4: Principles of Flight › Pressure › Density Altitude
Density Altitude SDP is a theoretical pressure altitude, but aircraft operate in a nonstandard atmosphere and the term density altitude is used for correlating aerodynamic performance in the nonstandard atmosphere. Density altitude is the vertical distance above sea level ... propeller is less efficient in thin air • Lift because the thin air exerts less force on the airfoils Density altitude is pressure altitude corrected for nonstandard temperature. As the density of the air increases (lower density altitude), aircraft performance increases…
- Chapter 9: Basic Flight Maneuvers › Turns › Technique
helicopter is in a climbing or descending attitude rather than that of level flight. If a so-called simultaneous entry (entering a turn while, at the same time, climbing or descending) is desired, merely combine the techniques of both maneuvers ... climb or descent entry and turn entry. When recovering from a climbing or descending turn, the desired heading and altitude are rarely reached at the same time. If the heading is reached first, stop the turn and maintain the climb…
