- 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…
- SKIPPING › GLASSY WATER TAKEOFFS
When using this technique, be careful not to lift the wing so much that the opposite wing contacts the water. Obviously, this would have serious consequences. Once the seaplane lifts off, establish a positive rate of climb to prevent inadvertently ... flying back into the water. Another technique that aids glassy water takeoffs entails roughening the surface a little. By taxiing around in a circle, the wake of the seaplane spreads and reflects from shorelines, creating a slightly rougher surface that…

right side of the seaplane. Density altitude is particularly important in seaplane flying. High, hot, and humid conditions reduce engine power and propeller efficiency, and the seaplane must also attain a higher water speed in order to generate the lift ... required for takeoff. This increase in water speed means overcoming additional water drag. All of these factors combine to increase takeoff distances and decrease climb performance. In high density altitude conditions, consider not only the length of the water…
- Chapter 3. Airspace › Section 2. Controlled Airspace › 3-2-6. Class E Airspace
Pilots should refer to the airport page in the applicable Chart Supplement for surface area status information. 2. Extension to a surface area. Class E airspace may be designated as extensions to Class B, Class C, Class D, and Class ... surface areas. Class E airspace extensions begin at the surface and extend up to the overlying controlled airspace. The extensions provide controlled airspace to contain standard instrument approach procedures without imposing a communications requirement on pilots operating under VFR. Surface…
- LANDING › GLASSY WATER LANDING
GLASSY WATER LANDING Flat, calm, glassy water certainly looks inviting and may give the pilot a false sense of safety. By its nature, glassy water indicates no wind, so there are no concerns about which direction to land, no crosswind ... consider, no weathervaning, and obviously no rough water. Unfortunately, both the visual and the physical characteristics of glassy water hold potential hazards for complacent pilots. Consequently, this surface condition is frequently more dangerous than it appears for a landing seaplane…

Rectangular Solid The formula for the surface area of a rectangular solid [Figure 3-24] is given as: Surface area = 2 × [(width × length) + (width × height) + (length × height)] = 2 × [(w × l) + (w × h) + (l × h)] Cube The formula for the surface ... area of a cube [Figure 3-25] is given as: Surface area = 6 × (side × side) = 6 × s2 Example: What is the surface area of a cube with a side measure of 8 inches? Surface area = 6 × (side × side…
