121-140 Flashcards
Are you able to re-stow the fire handle after you have pulled it?
You can restow it. Can’t find answer about it resetting SOVs
Why are we required to push the cargo smoke button an additional time to discharge the low rate bottle on the ground?
Low rate won’t automatically discharge on the ground because it assumes there will be outside fire assistance and we don’t want it to discharge for 75 minutes
According to the SOPM, how long should we delay APU start before pushback?
10 minutes prior to push
What is the minimum temperature to start the APU?
-54 C
When shutting down the APU, what is the difference between pushing the EMERG STOP button and turning the APU switch to OFF?
EMER STOP button closes APU fuel shutoff valve with no cool down period. OFF initiates normal APU shutdown.
If performance requires ECS OFF, what operational considerations exist with respect to the APU?
ECS off = APU on for pressurization and air conditioning.
How long can the aircraft be unattended while the APU is running?
No more than 5 minutes (SOPM 02-04.4)
What is the maximum speed for the windshield wipers?
250 kts
Do the wipers operate together or independently?
Independently
When should taxi lights be on? Off?
On: Movement on ground through 10,000, 18,000 ft descent check.
Off: Stationary on ground, or pulling into gate.
When does the SOPM require the NAV lights to be switched on?
When electrical power is applied to the aircraft (SOPM 04-01.8)
How do you initiate a hydraulic PBIT?
H-PBIT begins when all 3 hydraulic systems are pressured and reservoir temp is at least +10C (SOPM 04-01.11)
List the ways in which a hydraulic PBIT can be interrupted?
Interrupted when any flight control surface is moved. (SOPM 04-01.11)
What temperature will inhibit the HPBIT from running? Why?
Less than 10 degrees C. Because it’s too cold to properly move and could cause a flt cntrl no dsptch
When is a hydraulic warm up required?
Reservoir temperature below -18C prior to engine start
