Daily tasks not in 5, 9 or Aeromed Flashcards
(5-22) FUEL BOOST PUMP LIMITATIONS
Fuel boost pumps shall be ON during normal operations.
(5-19) ENGINE RPM LIMITATION, WARNING
Use of the throttle to control rpm is not authorized. (Refer to Chapter 9, Emergency Procedures and the USAAVNC Flight Training Guide for exceptions.)
(9-27) FIRE NOTE
Although the agent contained in this extinguisher is not toxic, it may cause skin irritation. In case of contact with agent, flush affected area with clean cool water.
(9-27) FIRE CAUTION
If aircraft fire occurs on ground while using Ground Power Unit (GPU); the GPU should be shutdown immediately.
(9-42) ENGINE OUT WARNING SYSTEM
When this system is activated, an intermittent audio signal is produced and the ENG OUT light is illuminated (GAS PRODUCER less than 55% +- 3).
TUNDERSTORMS
Minimize effect
To minimize the effects of thunderstorms encountered in flight, perform the following:
- Adjust torque to a value corresponding to maximum endurance airspeed.
- Check that all occupants are seated with seat belts and harnesses tightened. PITOT HTR switch(es) - ON.
- Avionics - Reduce volume on any equipment affected by static.
- Interior lights - Adjust to full bright at night to minimize blinding effect of lightning.
TUNDERSTORMS
In the storm
- Maintain a level attitude and constant power setting. Airspeed fluctuations should be expected and disregarded.
- Maintain original heading, turning only when necessary.
- The altimeter is unreliable, due to differential barometric pressures within the storm. An indicated gain or loss of several hundred feet is not uncommon and should be allowed for in determining minimum safe altitude.
LIGHTNING STRIKE
WARNING
Avoid Flight in or near thunderstorms, especially in areas of observed or anticipated lightning discharges.
LIGHTNINGSTRIKE
NOTE
Abnormal operating noises almost always accompany rotor damage, but loudness or pitch is not valid indications of the degree of damage sustained.
LIGHTNING STRIKE
If lightning strike occurs, or is expected, the following precautions are recommended to minimize further risk.
- Reduce airspeed as much as practical to maintain safe flight.
- Avoid abrupt control inputs.
TREATMENT OF HYPOXIA
100% oxygen or decent below 10000’
Symptoms of hypoxia
- Air hunger
- Apprehension
- Fatigue
- Nausea
- Headache
- Dizziness
- Hot or cold flashes
- Euphoria
- Anger
- Blurred vision
- Tunnel vision
- Numbness
- Tingiling
- Denial
Define spatial disorientation
- An individual´s inability to determine his or her position, attetude, and motion relative to the earths surface
- When SD occures, pilots are unable to see, belive, intepret, or prove information delivered from their flight instruments. They instead rely on false information provided by their senses
What are the types of spatial disorientation?
- Type I - Unrecognised
- An aviator does not perceive any indication of SD or thinks anything is wrong
- Type II - Recognised
- The pilot perceives a problem resulting from SD but might not recognize it as SD
- Type III - Incapacitating
- The pilot expriances such an overwhelming sensation of movment that he or she cannot otient using visual cues or the aircraft instruments.
Treatment to Spatial Disorientation
- Refer to instruments and develop good cross-check technique.
- Delay intuitive actions long enough to check both visual references and instruments.
- Transfer the controls (two pilots rarely affected by SD at the same time)
