- Chapter 6: Flight Controls › Flight Control Systems › Leading Edge Devices
slat allows the air below the wing to flow over the wing’s upper surface, delaying airflow separation. Leading edge flaps, like trailing edge flaps, are used to increase both CL-MAX and the camber of the wings. This type ... leading edge device is frequently used in conjunction with trailing edge flaps and can reduce the nose-down pitching movement produced by the latter. As is true with trailing edge flaps, a small increment of leading edge flaps increases lift…
- Chapter 11: Helicopter Emergencies and Hazards › Dynamic Rollover › Critical Conditions
Critical Conditions Certain conditions reduce the critical rollover angle, thus increasing the possibility for dynamic rollover and reducing the chance for recovery. The rate of rolling motion is also a consideration because, as the roll rate increases, there ... reduction of the critical rollover angle at which recovery is still possible. Other critical conditions include operating at high gross weights with thrust (lift) approximately equal to the weight. Refer to Figure 11-5. The following conditions are most critical…

more conservative than those required by regulations for VFR flight. In addition, a thorough preflight and understanding of weather conditions that may contribute to the risk of IMC developing along a planned route of flight is essential for safety. Pilots ... should recognize deteriorating weather conditions so the route of flight can be changed or a decision made to terminate the flight and safely land at a suitable area, well before IIMC occurs. If weather conditions deteriorate below the pilot…
- Chapter 12: Night Operations › Helicopter Night VFR Operations
Helicopter Night VFR Operations While ceiling and visibility significantly affect safety in night VFR operations, lighting conditions also have a profound effect on safety. Even in conditions in which visibility and ceiling are determined to be visual meteorological conditions ... night may be compromised. The ability to discern these objects and terrain is referred to as the “seeing condition,” and is related to the amount of natural and man-made lighting available, and the contrast, reflectivity, and texture of surface…
- Chapter 16: Cabin Environmental Control Systems › Air Cycle Air Conditioning › Cabin Temperature Control System
Figure 16-69. The air cycle air conditioning system of a DC-10 transport category aircraft uses only one heat exchanger per ACM. Cabin temperature pickup units and duct temperature sensors used in the temperature control system are thermistors. Their ... temperature sensors are strategically located to provide useful information to control cabin temperature. [Figure 16-71] Vapor Cycle Air Conditioning The absence of a bleed air source on reciprocating engine aircraft makes the use of an air cycle system impractical…
- 14 CFR Part 135 — Operating Requirements: Commuter and on Demand Operations and Rules Governing Persons on Board Such AircraftOpen14 CFR § 135.227 Icing conditions: Operating limitations.
Icing conditions: Operating limitations. (c) No pilot may fly under IFR into known or forecast light or moderate icing conditions or under VFR into known light or moderate icing conditions, unless— (1) The aircraft has functioning deicing or anti-icing ... airplane meets transport category airplane type certification provisions, including the requirements for certification for flight in icing conditions. (d) No pilot may fly a helicopter under IFR into known or forecast icing conditions or under VFR into known icing conditions…
