Q

Compensated Baro-VNAV system applies FMC cold temperature corrections for RNP approaches
• An UNCOMPENSATED Baro-VNAV system does NOT apply FMC cold temperature corrections for RNP approach altitudes
Is the 787 compensated Baro-VNAV system or uncompensated?

A

The 787 has an uncompensated Baro-VNAV system (for now)

Q

Since Baro-VNAV depends on the altimeter it is subject to altimeter ERRORS
• When flying approaches in non-ISA conditions true altitude may be lower/higher
• Glide path angle will also vary due to temperature

What is our procedure for Baro VNAV RNP approaches (0.3)

A

Confirm TLim for approach.
• When reported OAT is below minimum OAT
or above the maximum OAT on the RNP AR
APCH approach chart, the approach is not
authorized.
• When the reported OAT is at/below 0° C and
at or above the minimum OAT published on the
chart, temperature correct the DA only.
• Only approaches specified in the
Jeppesen Route Manual 10-10 pages
and loaded from the database may be
conducted.

Q

Unless visual reference has been established, when should a missed approach be initiated?

A

missed approach should be initiated when:

• Flight instrument failure occurs which affect the
ability to safely complete the approach.

• Navigation instruments show significant
disagreement.

• Altimeter error exceeding 100 ft at FAF crossing.
EICAS message.

Q

Does a failure of one GPS require a go around on a RNAV approach?

A

A Dual GPS failure no longer requires a
go around on its own.
• The IRS system provides an accurate
position to the FMC
• If the position information degrades to a
point of inaccuracy then a go around will
be triggered by:
• NAV UNABLE RNP or
• FMC VERIFY POSITION

Q

In the event of a GA between MAXEN and
the DA what is the maximum speed you
could fly?

A

The maximum speed you
could fly
• When a missed approach is
conducted inside the FAF on an RF leg,
the maximum speed of 165 KIAS must
be respected until past the end of the RF
leg at the DA then 265 in the GA

Q

What are some considerations for flight in sever turbulence?

A

Seatbelt signs “ON”
• Delay flap extension as long as possible
• Use V/S and autothrottle for climb and descent
• Use EICAS guidance when VNAV is engaged, to manually set thrust if excessive changes occur.

Q

What is the difference between land 2 and land 3

A

Land 3 = Fail operational = CAT IIIB = no decision height = 3 autopilots

Land 2 = Fail passive = CAT IIIA = Decision Height = 2 autopilots

No Auto land = manual landing

Q

What does fail operational vs fail passive

A

Fail operational means it can withstand a failure and still complete an auto land. With 3 autopilots if one fails then the other two can

Fail passive means two autopilots comparing, if one failure, will not protect the landing

Q

What is the difference between an DH and AH

A

Decision height is the height you need visual reference to continue the landing

Alert Height (200ft) is the height at which you can continue the landing even if a failure occurs.

So Failure happens at 300 ft go around
Failure at 150 ft continue

Q

Why is the Max T/O distance (377nm) shorter than the max etops alternate difference

A

Because T/O is based on MTOW and low altitude

ETOPs alternates based on Wt and Altitude at CP based on data for the last 5 Years.

“Backing the airplane with use of reverse thrust is prohibited”

AOM 1 limitations

45
Q

What is the ground wind operating limits?
