Chapter 11: Aircraft Performance › Climb Performance Factors › Range Performance
This is the point of maximum endurance. Beyond this point, increases in airspeed come at a cost. Airspeed increases require additional power and fuel flow increases with additional power. Cruise flight operations for maximum range should be conducted so that ... aircraft obtains maximum specific range throughout the flight. The specific range can be defined by the following relationship. specific range = NM pounds of fuel or specific range = NM/hour pounds of fuel/hour or specific range = knots fuel flow If maximum specific…

Chapter 4. Air Traffic Control › Section 4. ATC Clearances and Aircraft Separation › 4-4-12. Speed Adjustments
Instruct the pilot to “resume published speed.” Resume published speed is issued to terminate a speed adjustment where speed restrictions are published on a charted procedure. NOTE-When instructed to “comply with speed restrictions” or to “resume published speed ... anticipates pilots will begin adjusting speed the minimum distance necessary prior to a published speed restriction so as to cross the waypoint/fix at the published speed. Once at the published speed, ATC expects pilots will maintain the published speed until…

When complying with speed adjustment assignments, maintains an indicated airspeed within plus or minus 10 knots or 0.02 Mach number of the specified speed. b. Controller. 1. Assigns speed adjustments to aircraft when necessary but not as a substitute ... vectoring technique. 2. Adheres to the restrictions published in FAA Order JO 7110.65, Air Traffic Control, as to when speed adjustment procedures may be applied. 3. Avoids speed adjustments requiring alternate decreases and increases. 4. Assigns speed adjustments…

Chapter 11: Aircraft Performance › Performance Speeds
Performance Speeds True airspeed (TAS)—the speed of the aircraft in relation to the air mass in which it is flying. Indicated airspeed (IAS)—the speed of the aircraft as observed on the ASI. It is the airspeed without correction ... instrument errors. (CAS is equal to TAS at sea level in standard atmosphere.) The color coding for various design speeds marked on ASIs may be IAS or CAS. Equivalent airspeed (EAS)—the ASI reading corrected for position (or installation…
