Between CAS/MACH transition and 12000 ft - 290KIAS
From 12000 to 10000 - Decreases linearly from 290kias to 250kias
Below 10000, 250kts until - Deceleration to/for approach speeds
How does the FMS calculate TOD?
Based upon the angle and speeds entered in the FMS performance Init pages
How and when can the FMS descent angle be changed?
Any change can be make on the performance init or perf descent pages during FMS intialization or in flight.
What is the procedure if a flight path change needs to be performed while desdcending with VPATH engaged?
- Change to FPA mode
- execute lateral direct to
- execute the vertical direct to
- then change back to VNAV
In the case of early or late descents what function should be used?
Descend NOW
What is recommended when being radar vectored regarding descent modes?
Disengage VNAV and set the speed knob to manual
What does the FMS use to calculate idle descents?
A certain wieght at the top of FMS VPATH
When may the speed brakes be used?
When flight conditions or ATC requires
What are the deceleration distances for the ERJ 175?
speed brakes down
level flight
1000 FPM descent
Speed brakes up
level flight
100FPM
speed brakes down
level flight - 1 NM for each 10kts of deceleration
1000 FPM descent - 2 NM for each 10kts of deceleration
Speed brakes up
level flight - .5 NM for each 10kts of deceleration
100FPM - 1 NM for each 10kts of deceleration
When must a landing performance analysis using ACARS or the TLR be made?
Conditions are different than the planned data or flight crew needs to know absolute performance capabilities in abnormal or emergency situatuions. Practically speaking, it is done for every landing.
When would it be appropriate to land on a runway that does not mee the ACARS/TLR mimimum criteria?
Energency with no other options
when will auto brakes be used?
According to the runway conditions and type of operation
On the FMS page, what must be assigned to descent waypoints?
DES
What benefits result from a flap 5 landing?
Lower fuel consumption and lower noise levels
What benefits result from a full flap landing?
- Shorter landing length
- greater control on contaminated runways
How may landing speeds be obtained?
- ACARS
- TLR
- QRH
If the STALL PROT ICE SPEED EICAS message is displayed what must be done in regards to VREF
10kt addition must be made to the modified VREF
If VAC is less than VREF set VAC to ____________
equal to VREF
Are LAHSO operations approved?
YES
Who has the final authority to accept/decline LAHSO instructions?
PIC
What are the weather limitations on LAHSO operations?
with PAPI/VASI
- 3 miles vis
- 1000 ft ceiling
without PAPI/VASI
- 3 miles vis
- 1500 ft ceiling
no windshear reported in previous 20 min
tailwind to LAHSO runway less than 3 kts
When must the approach be stablized when performing LAHSO operations?
- 1000ft for straight in approaches
- 500ft/MDA, whichever is lower, for circling after an IAP
Are LAHSO operations approved on wet runways?
NO
When must touchdown occur when performing a LAHSO landing?
First 1/3 of available landing distance or first 3000ft, whichever is less
Can LAHSO be accepted if a thrust reverser is deferred/INOP?
NO
No MEL can exist that affects the stopping capability of the aircraft
Can LAHSO be performed at night?
Only at airports with approved nighttime LAHSO lighting systems
At what altitude can a LAHSO clearance no longer be issued/accepted?
Below 1000ft AGL on final approach
When must a rejected landing be performed while performing LAHSO?
Unable to land in the first 1/3 or 3000ft
anytime the PIC determines it is appropriate
On performing a rejected LAHSO landing, fly the ___________or __________
published missed approarch
instructions given by ATC
Which SKW airports have approved nightime LAHSO systems?
- ORD
- DFW
- YYC
- STL
