Chapter 8: Flight Instruments
chapter addresses the pitot-static system and associated instruments, the vacuum system and related instruments, gyroscopic instruments, and the magnetic compass. When a pilot understands how each instrument works and recognizes when an instrument is malfunctioning…

Chapter 8: Flight Instruments › Electronic Flight Display (EFD) › Air Data Computer (ADC)
system malfunction, the ADC can quickly be removed and replaced in order to decrease downtime and decrease maintenance turn-around times. Altitude information is derived from the static pressure port just as an analogue system does; however, the static pressure ... progressing. Figure 8-15. Teledyne’s 90004 TAS/Plus Air Data Computer (ADC) computes air data information from the pitot-static pneumatic system, aircraft temperature probe, and barometric correction device to help create a clear picture of flight characteristics…

Chapter 4: Helicopter Components, Sections, and Systems › Main Rotor System › Rigid Rotor System
comprised of glass fiber reinforced material. The hub is a single piece of forged rigid titanium. The rigid rotor system is very responsive and is usually not susceptible to mast bumping like the semirigid systems because the rotor hubs ... fuselage to move together as one entity and eliminates much of the oscillation usually present in the other rotor systems. Other advantages of the rigid rotor include a reduction in the weight and drag of the rotor…

Chapter 8: Flight Instruments › Blocked Static System
Blocked Static System If the static system becomes blocked but the pitot tube remains clear, the ASI continues to operate; however, it is inaccurate. The airspeed indicates lower than the actual airspeed when the aircraft is operated above the altitude ... where the static ports became blocked because the trapped static pressure is higher than normal for that altitude. When operating at a lower altitude, a faster than actual airspeed is displayed due to the relatively low static pressure trapped…

Chapter 8: Flight Instruments › Blocked Pitot System
Figure 8-10. Blocked pitot system with clear static system. It can be inferred that airspeed indication must be based upon a relationship between these two pressures, and indeed it is. An ASI uses the static pressure as a reference ... case is kept at this pressure behind the diaphragm. On the other hand, the dynamic pressure through the pitot tube is connected to a highly sensitive diaphragm within the ASI case. Because an aircraft in zero motion (regardless of altitude…

Chapter 7: Aircraft Systems › Heating System › Exhaust Heating Systems
Exhaust Heating Systems Exhaust heating systems are the simplest type of aircraft heating system and are used on most light aircraft. Exhaust heating systems are used to route exhaust gases away from the engine and fuselage while reducing engine noise ... exhaust systems also serve as a heat source for the cabin and carburetor. The risks of operating an aircraft with a defective exhaust heating system include carbon monoxide poisoning, a decrease in engine performance, and an increased potential for fire…
