Please describe the Pitot-Static system
The system received ram pressure and static pressure then send to Pitot-static instrument.
These instruments convert pressure and send to 3 indicators.
1.Airspeed indicator measuring differential pressure between dynamic pressure from pitot tube and static pressure from static port.
2 and 3. For Altimeter and Vertical speed indicator use only static pressure to measure changed pressure varies by altitude in Aneroid wafers and Diaphragm respectively.
Please describe the Pitot tube’s malfunctions
Malfunction may occur by blockage of ice, dirt or insect.
Pitot tube malfunction
- Pitot tube clear but drain hole blocked: A/S will read more than actual speed
- Pitot tube blocked but drain hole clear. A/S will slowly drop to “0”
- Pitot tube and drain hole blocked: A/S will related to changing in altitude
High altitude -> A/S increase
Low altitude -> A/S decrease
Correction by turn on Pitot heat switch
Please describe the static port’s malfunction
Malfunction may occur by blockage of ice, dirt or insect.
Static port malfunction
1.Blocked static port: Inaccurate Airspeed, Freeze Altimeter and Freeze Vertical speed indicator.
Correction by use alternate static port if cannot or didn’t equip try to break Vertical speed indicator gauge
Visual flight rules condition (VFR)
- Operate sunrise to sunset / Ceiling more than 1,500 ft.
- Visibility 5-8 km. When operate at altitude below 10,000 ft.
- Visibility 8-10 km. When operate at altitude between 10,000-20,000 ft.
- Operate altitude not more than 20,000 ft.
- Do not operate in transonic (0.5M-1.2M) or supersonic (1.2M-3M)
- East round route (0-179 degree) operating altitude odd thousand +500 ft. When altitude more than 3000 ft. (3500, 5500, 7500, …)
- West round route (180-359 degree) operating altitude even thousand +500 ft. When altitude more than 3000 ft. (4500, 6500, 8500, …)
- Maintain clear of cloud 2,000 ft. Horizontal, 1,000 ft. above and 500 ft. below
- Operating altitude above congested area more than 1,000 ft.
- Operating altitude above uncongested area more than 500 ft.
Please describe the Gyroscopic system
This system base on 2 fundamental concepts
- Rigidity in space
- Precession
Gyroscope is able to remain in fixed position on plane in which it originally spinning.
There are 3 types of gyroscope instruments
- Attitude indicator
- Heading indicator
- Turn coordinator
Attitude and Heading indicator received power from vacuum pump system and normally operate when suction gauge is on green (4.5 - 5.4)
It will malfunction if suction gauge is out of range. If vacuum system failed these 2 instruments won’t work and use magnetic compass instead of Heading indicator
Turn coordinator powered by an electrical system.
