Question 1

What is Mode A?

Answer 1

Basic identification using four-digit squawk

Question 2

What is Mode C?

Answer 2

Altitude reporting in addition to identification by four-digit squawk

Question 3

What is mode S?

Answer 3

Enhanced data reporting (speed, heading)

1.
2.
3.
4.

Answer 4

1. When operating in Class A, B, or C airspace
2. Above 10,000 feet MSL except below 2500 AGL
3. Within 30 nautical miles of a class B airport (Mode C veil)
4. Above and within the lateral boundaries of class B or C airspace up to 10,000 feet

Question 5

116th SOP regarding transponders

Answer 5

Both tactical and non-tactical transponders will be operated IAW regulations and SPINS. When not
restricted, the Battalion Commander will determine when ADS-B out operations, TCAS off operations, or
ADS-B out and TCAS off operations are required IAW and HQDA EXORD 107-20. The Battalion
Commander may delegate this to the low-risk approval authority on a case-by-case basis.

Question 6

Transponder RAW requirements

Answer 6

High risk (H13): ADS-B Out Off and/or Mode S off within the NAS.

During missions with ADS-B Out Off and/or Mode S Off, three (3) LOW risk items
listed on the RAW will elevate the risk and require MODERATE risk approval. Two
(2) MODERATE risk items will elevate the risk and an additional HIGH risk item. If
a total of two (2) HIGH risk items are identified, the mission will be assessed as an
EXTREMELY HIGH risk.

Question 7

When will you get the emergency descent caution?

Answer 7

EMERGENCY DESCENT (Caution) will be annunciated if EDM
mode was MANUALLY selected.

Question 8

When will you get the emergency descent warning?

Answer 8

When Automatic Emergency Descent mode has activated.

Question 9

When does the emergency descent mode automatically engage?
1.
2.
3.

Answer 9

1. cabin altitude exceeds 14,500 ft
2. Airplane altitude is higher than 25,000 ft
3. Autopilot is engaged

Question 10

What occurs when emergency descent mode occurs automatically?
1.
2.
3.
4.
5.
6.
7.
8.

Answer 10

1. Emergency descent warning on CAS
2. Aural “Emergency Descent”
3. Heading becomes lateral mode commanding 90 degree turn to the left (can be changed)
4. EDM shown in vertical mode with a target altitude of 15,000 feet (can be changed)
5. Speed target of VMO-10 / MMO-.02 then 250kias at ALTS CAP
6. EDM becomes the Autothrottle mode with AT activation if not previously engaged and power commanded to idle
7. Passenger oxygen automatically deploys with PAX OXYGEN ON CAS message
8. Automatically squawks 7700

Question 11

How to deactivate emergency descent mode?

Answer 11

Disconnect autopilot

Question 12

TIME OF USEFUL CONSCIOUSNESS - GRADUAL DECOMPRESSION
ALTITUDE TIME

Answer 12

50,000 ft
6 − 9 seconds

45,000 ft
9 − 15 seconds

40,000 ft
15 − 20 seconds

35,000 ft
30 − 60 seconds

30,000 ft
1 − 3 minutes

25,000 ft
3 − 5 minutes

20,000 ft
5 − 10 minutes

12,000 − 18,000 ft
20 − 30 minutes

Question 13

Negative pressure relief during emergency descent

Answer 13

During an emergency descent without cabin
airflow, when the outside pressure becomes slightly greater than cabin pressure, the SFV opens
to control negative pressure at a value lower than or equal to 0.5 psid. A warning message is
displayed on the EICAS and the digital readout changes to red.

Question 14

Altitude rate limit during emergency descent

Answer 14

The altitude rate limitation is not active in the case of emergency depressurization and ditching.

Question 15

What are the differences between automatic and manual EDM?

Answer 15

1. Caution vs warning
2. Automatic automatically squawks 7700 manual does not
