- 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…
- 14 CFR § 91.179 IFR cruising altitude or flight level.
cruising altitude or flight level. Unless otherwise authorized by ATC, the following rules apply— (a) In controlled airspace. Each person operating an aircraft under IFR in level cruising flight in controlled airspace shall maintain the altitude or flight level assigned ... that aircraft by ATC. However, if the ATC clearance assigns “VFR conditions on-top,” that person shall maintain an altitude or flight level as prescribed by § 91.159. (b) In uncontrolled airspace. Except while in a holding pattern of 2 minutes…

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…
- 14 CFR Part 91, Appendix G to Part 91—Operations in Reduced Vertical Separation Minimum (RVSM) Airspace
amendment, revocation, or restriction include, but are not limited to, an operator's: (a) Committing one or more altitude-keeping errors in RVSM airspace; (b) Failing to make an effective and timely response to identify and correct an altitude-keeping ... error; or (c) Failing to report an altitude-keeping error. Section 8. Airspace Designation RVSM may be applied in all ICAO Flight Information Regions (FIRs). Section 9.

- 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…

Supplemental oxygen. (a) General. No person may operate a civil aircraft of U.S. registry— (1) At cabin pressure altitudes above 12,500 feet (MSL) up to and including 14,000 feet (MSL) unless the required minimum flight crew is provided ... with and uses supplemental oxygen for that part of the flight at those altitudes that is of more than 30 minutes duration; (2) At cabin pressure altitudes above 14,000 feet (MSL) unless the required minimum flight crew is provided…
