- Chapter 5. Air Traffic Procedures › Section 5. Pilot/Controller Roles and Responsibilities › 5-5-9. Speed Adjustments
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 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…
- Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Loss of Tail Rotor Effectiveness (LTE)
catastrophic. LTE is an aerodynamic condition and is the result of a control margin deficiency in the tail rotor. It can affect all single-rotor helicopters that utilize a tail rotor. The design of main and tail rotor blades ... will not nullify the phenomenon entirely. Translational lift is obtained by any amount of clean air through the main rotor disk. Chapter 2, Aerodynamics of Flight, discusses translational lift with respect to the main rotor blade, explaining that the more…
