What are the AMS subsystems? |
- Pneumatic system - Environmental control system - Main door pressurised seal system - Auxiliary fuel tanks pressurisation system - Pressurisation system - Anti-ice - Engine Start - Oxygen |
|
|
What happens when you PUSH OUT the BLEED 1 (2) button? |
It closes the respective PRSOV |
|
|
What happens when you push the DUMP button in? |
- Rapid cabin depressurisation - Opens the outflow valve - Commands the cabin inflow and recirculation fan to OFF |
|
|
At what rate does the cabin ALT controller control altitude? |
50ft/min steps |
|
|
At what RoC change will the cabin RoC indication turn Amber? |
+/- 2,500fpm to +/- 6,000fpm |
|
|
When will the cabin altitude turn amber? |
Between 8,300ft and 10,000ft, +/- 200ft |
|
|
When will the cabin altitude turn red? |
Above 10,000ft |
|
|
When is the HI FIELD indication present? |
Take off and landing from a field of higher elevation than 8,300ft. |
|
|
With the APU on, when will the source of the bleed transition from the APU to the engines? |
TLA greater than 50⁰ |
|
|
In case of loss of both engines, can the APU supply bleed air to the engines? |
Yes |
|
|
What is the normal operation of the XBSOV? (Cross bleed shutoff valve) |
Open |
|
|
When will the XBSOV automatically close? |
- Bleed leakage - Overpressure - Engine fire - Failure condition |
|
|
If using a ground air starter to start the engines, where should the APU bleed be? |
Turned off to avoid the use of 2 bleeds |
|
|
How many PACKs are there? |
2, (one is a backup) |
|
|
If the PACK backup is used, what temperature is maintained? |
24⁰C |
|
|
When will the main door seal inflate? |
- WOW indicates in flight - Airplane KCAS above 60kts - DOOR PAX SEAL FAIL CAS is not displayed |
|
|
What does the CPCS (cabin pressure control system) consist of? |
- One ECMU - One OFV - One NPRV - One PRV |
|
|
Under normal operation, what controls the outflow valve? |
The ECMU (electronic control and monitoring unit) |
|
|
What is the normal position of the NPRV and the PRV |
Closed, only open if differential pressure limits are reached. |
|
|
When will the PRV open? |
If the differential pressure is between 9.84 - 10.04 psi |
|
|
When will the CABIN DELTA-P FAIL CAS msg be displayed? |
If the differential pressure reaches 10.14psid in auto, or 10.30psid in manual mode |
|
|
When will the NPRV open? |
If differential pressure between the cabin and the surrounding environment exceeds -0.3psid |
|
|
When would you use the DUMP function? |
- Emergency evacuation - Smoke evacuation - For fast cabin depressurisation |
|
|
In the automatic control dump operation, what rate if change, and to what altitude, is the cabin depressurised? |
2,000fpm up to 12,000ft |
|
|
In the manual control dump operation, what rate if change, and to what altitude, is the cabin depressurised? |
No limit to the rate of change, will disable at 14,800ft +/-200ft |
|
|
When will the CABIN ALT HI CAS msg be displayed? |
10,000ft cabin altitude, or 14,500ft when the oxygen selector is moved to PAX OVRD position |
|
|
At what temperature will the ECS CABIN (CKPT) DUCT OVTMP CAS be displayed? |
85⁰C |
|
|
What happens when the HIGH FIELD indication is present? |
Shifts the alarm for high cabin altitude from 10,000ft to 14,600ft (both +/-200ft) |
|
