Block 2 Flashcards
You have just selected the APU MASTER SW pb to ON. You now select the APU START pb to ON. What 2 things will the ECB wait on before engaging the electric starter?
Th ECB will not engage the electric starter UNTIL
(1) The power-up self test is completed satisfactorily
(2) The air intake flap is fully open
The APU START pb has AVAIL illuminated, the STS page reads NW STRG DISC APU AVAIL and the APU page reads AVAIL These indications indicate that:
The APU has reached normal operating speed and is ready to provide electrical power and bleed air
What does the ECB provide? (4) It provides monitoring of, and sequencing of….
- APU N speed and EGT monitoring
- Start and shut down sequencing
- Bleed air output monitoring
- FAULT monitoring and reporting
Ambient air is routed to the APU compressor through an INTAKE FLAP. How is this mechanism driven/operated, and where is the flap located?
ELECTRICALLY operated intake flap (controlled by the ECB - not manually)
Located beneath the APU compartment
Fuel for APU operation is normally supplied from:
The LEFT wing tank INNER cell, through the ENGINE 1 feed line
What is true concerning the APU oil system, and when it will auto shutdown?
The ECB shuts down the APU automatically for low oil PRESSURE, but does NOT shut it down for low oil QUANTITY
Select the control that enables you to turn off the APU generator when the APU is operating
You would push the APU GEN pb so that “OFF” is illuminated in white on the ELEC control panel
APU bleed air output is used for:
Engine starting, engine conditioning
What is the APU fire detection and protection system equipped with?
The system is equipped with TWO HEAT DETECTION LOOPS and ONE Halon Bottle
When an APU fire occurs on the ground, what 3 things will occur?
- The ECB automatically shuts down the APU
- A red APU fire light illuminates on the External Power Panel near the nose gear and an external HORN, located at the nose gear, sounds
- The APU Halon fire bottle is DISCHARGED automatically
Radar malfunctions are displayed:
On the NDs
Intensity of the radar display is controlled by:
The outer ring of the ND brightness control knob
True or False: According to this ND, clear air turbulence is being detected along your flight path.
False!! You can not see CAT on you radar displays
With the GAIN selector in the AUTO position, you have selected a sensitivity level:
That is calibrated for optimum weather display
With the TILT selector knob set to 0, the radar beam is pointed:
At the horizon as defined by the IRU 1 (NOT along the horizontal axis of the a/c)
Areas of turbulence are only displayed up to __ NM
UP TO 40 miles
With this GPWS panel configured as shown, which statement below is true? (picture of the GPWS Panel with the SYS pb illuminating “OFF”)
All 5 of the GPWS Basic Mode warnings are inhibited (Terrain category is NOT affected)
True or False: You must make sure the loudspeakers are turned up loud enough so you can hear the aural GPWS warnings.
FALSE, GPWS warnings/indications are played at max volume always
You are flying at a low altitude. The GPWS is operating normally, and the TERR ON ND pb on your side of the flight deck is selected ON. You can determine from the ND that: (picture of the ND with all black radar return)
All terrain within the range selected on the ND is MORE THAN 2000’ BELOW your current altitude
Is the Terrain Clearance Floor predictive or non-predictive? What does this mean to us?
NOT Predictive - meaning the a/c must actually PENETRATE the TCF to trigger a warning!
You have the “TERR ON ND” pb selected to ON, and see red and amber solid radar returns of terrain on your ND, and hear “TERRAIN AHEAD, PULL UP.” this means that you are:
Within 30 seconds (vs 60 seconds) of hazardous terrain based upon your current flight path angle, track and speed relative to the terrain
According to this ND: (picture showing 3 traffic returns: 1 solid white diamond indicating -09 @ your 9, 1 solid yellow circle indicating -08 @ your 11, and one solid red square indicating -06 @ your 2)
You have proximate traffic at 9 o’clock, a TA (Traffic Advisory) at 11 o’clock, and an RA (Resolution Advisory) at 2 o’clock
What are the different traffic symbol depictions you can see on your ND?
Solid white diamond = proximate traffic
Solid yellow circle = traffic advisory
Solid red square = resolution advisory
PROXIMATE traffic:
Within 1,200’ vertically and 6nm laterally, not considered a threat and displayed on the ND as a solid white diamond
Which item causes a takeoff configuration warning when the thrust levers are placed to a takeoff thrust setting while on the ground but does not cause a warning when the T.O CONFIG key is pressed after engine start?
Parking brake set to ON (would not be external doors since engine has started)
What are 3 Exceptions (think a/c configuration) when testing the takeoff configuration warning:
- All external doors closed (only PRIOR to engine start)
- ENG FLEX TEMP NOT SET
- Parking brake NOT set
Windshear warnings (which are provided by the FACs) function when the a/c is:
- Below 1300’ AGL
- At FLAPS 1 or greater
What is the correct alerting priority in order of importance? (think about the 4 types of alerts)
Stall
Windshear
GPWS
TCAS
What is required for the TCAS system to detect and avoid conflict traffic? (think a/c equipment)
Mode C Transponder
What guidance is given during a TA verse an RA warning?
RA will provide vertical guidance!
What is the difference between Mode A and Mode C transponder?
- Mode C = altitude reporting based off pressure altitude
- Mode A is strictly transponder
- Terrain awareness display will appear on the what flight deck component? Is it manually or automatically turned on?
- ND
- Both
- Manually turned on, otherwise it is automatically displayed if there is a terrain warning
True or False: On board wx radar is instant (no delay/lag)
True!!
- G1000 wx radar is NOT “on board”
What is Radar Attenuation?
When there is a super strong (red) radar return and behind it, there is no return, looking like it is clear. This is called a Radar SHADOW.
- Path ATTENUATION correction is a feature that will usually be shown as a bar on the display saying you should probably not fly in that region (even though there is no precip return)
How do we turn our APU on?
Use the pbs on the mini APU Panel with the MASTER and START pbs
An ADVISORY for cold soak (different than a limitation) means what to us?
You CAN TRY if above 8,000’ for more than 1 hour, but it may not work since its cold (no guarantee)
