SYS 202 - Flight Instruments 2 Flashcards
Where is the AOA computer located?
On the avionics shelf under the front cockpit glare shield
What three sources send inputs to the AOA computer?
- AOA Vane on the left wingtip
- Flap Position Microswitch
- Landing Gear
When is the stick shaker activated?
15-16 Units of AOA
5-10 Knots above stall speed
When is the AOA indexer activated?
When gear is down and locked
What is the no wind maximum range and how is it displayed on the AOA gauge?
4.9 units
White triangle
What is the maximum endurance and how is it displayed on the AOA gauge?
8.8 Units
White Diamond
How does the AOA vane send information to the AOA computer?
The AOA aligns with the relative airflow and through a belt and pulley system, it drives a potentiometer which provides an electronic signal to the AOA computer.
What are the units for the green arc on the AOA Gauge?
10 to 11
What are the units for the red arc on the AOA Gauge?
18 units
Does the T-6 have an audible stall warning system?
No
What is the maximum Elapsed Time on the clock?
99 hours and 59 minutes
What does IDARS Stand For?
Integrated Data Acquisition Recording System
Under what two conditions will the green MAINT annunciator light up on the FDR?
- If the IDARS reaches approx. 80% full
2. An over-G in flight
How do ground crews download IDARS data?
Through the recorder maintenance connector in the left avionics bay
Where are aural tones generated?
By the AOA Computer in the front cockpit glare shield
The main annunciator panel displays what?
Red Warning Legends
Amber Caution Legends
Green Status Legends
The annunciator panel and the MASTER WARN and MASTER CAUT lights are interconnected. (T/F)?
True
Dos the FDR have the capability to record in cockpit voice?
No
How does the stick shaker work?
Small electric motor drives eccentric weight that shakes both front/rear control sticks\
While on the ground, the gauge and stick shaker are inhibited unless what?
AOA test switch is activated
What range of Gs does the accelerometer show?
-6 - +10G
How high can the countdown be set to?
59 minutes, 59 seconds
T/F: If the underlying cause of the annunciator panel light has been alleviated, extinguishing the switchlights also extinguishes the annunciator. Otherwise, the annunciator remains illuminated until the failure is fixed.
True
What is the DTM?
Data Transfer Module - Portable memory cartridge used for digital information storage, loading & retrieval of IAT, structures, engine, documentary, & BIT data in non-volatile memory
What is the DTMR?
Data Transfer Module Receptacle -
Permanently mounted receptacle for the DTM which provides interface between DTM & IDARS
