Air Data Flashcards
How many Static ports are located on the aircraft?
Two (one on each side of the fuselage tail section)
Static system 1 supplies:
- ADC 1.
- The standby instrument, through the Normal / Alternate static source switching valve, when the ALTERNATE STATIC SOURCE selector is in the Normal position (pushed).
Static system 2 supplies:
ADC 2
Where is the Alternate Static Source located?
The alternate static port, located inside the rear fuselage.
The alternate static port supplies a line routed to the Normal/Alternate static source switching valve.
Static pressure from the alternate line is only provided to the…
Standby Instuments
(NOT TO EITHER Air Data Computers ADC)
When the alternate static source is selected do NOT rely on indications from the…
Primary Flight Display
PFD Only refer to the standby instrument for airspeed and altitude.
Dynamic pressure is provided by…
Two heated pitot probes, one installed under each wing.
The left probe supplies Air Data Computer (ADC)…
Air Data Computer (ADC) 1 and the standby instrument.
The right probe supplies Air Data Computer (ADC) …
The right probe supplies Air Data Computer (ADC) 2.
How do you avoid Pitot Probe over heating on the ground?
To avoid probe overheating while on the ground, do not turn on the pitot heat for long periods.
Airplane air data system consists of…
…two separate static pressure systems, and two separate dynamic pressure systems.
Checklist Items:
Airspeed Indicating System Failure
- PITOT L/R & STALL HTR switch - Check ON
If symptoms persist:
ALTERNATE STATIC SOURCE selector - Pull thoroughly
Use standby instrument only.
If airpeed indication failure symptoms persist on the electronic standby instrument
Use Pitch and Torque presets to maintain adequate airspeed.
