PL.IV.A.S5
SkillEstablish recommended hovering altitude, ±1/2 of that altitude within 10 feet of the surface; if above 10 feet, ±5 feet.

- Chapter 11: Aircraft Performance › Takeoff and Landing Performance › Landing Performance
deceleration during the landing is identical to the effect on acceleration during the takeoff. The effect of pressure altitude and ambient temperature is to define density altitude and its effect on landing performance. An increase in density altitude increases ... landing speed but does not alter the net retarding force. Thus, the aircraft at altitude lands at the same IAS as at sea level but, because of the reduced density, the TAS is greater. Since the aircraft lands at altitude…
- 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 11: Aircraft Performance › Takeoff and Landing Performance › Runway Surface and Gradient
Runway Surface and Gradient Runway conditions affect takeoff and landing performance. Typically, performance chart information assumes paved, level, smooth, and dry runway surfaces. Since no two runways are alike, the runway surface differs from one runway to another, as does ... runway gradient or slope. [Figure 11-15] Runway surfaces vary widely from one airport to another. The runway surface encountered may be concrete, asphalt, gravel, dirt, or grass. The runway surface for a specific airport is noted in the Chart…
- Chapter 11: Aircraft Performance › Performance Charts › Sample Problem 11
affected by variables similar to those affecting takeoff performance. It is necessary to compensate for differences in density altitude, weight of the airplane, and headwinds. Like takeoff performance charts, landing distance information is available as normal landing information, as well ... Problem 11 Refer to Figure 10-32. This example makes use of a landing distance table. Notice that the altitude of 1,250 feet is not on this table. It is, therefore, necessary to interpolate to find the correct landing…
- 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…
- LANDING › GLASSY WATER LANDING
Another technique is to make the final approach over land, crossing the shoreline at the lowest possible safe altitude so that a reliable height reference is maintained to within a few feet of the water surface. When adequate visual references ... available, make glassy water landings by establishing a stable descent in the landing attitude at a rate that will provide a positive, but not excessive, contact with the water. Recognize the need for this type of landing in ample time…
