FCOM 1 Hashtaged Limitations (memory items)

Question 1

Turbulent air penetration speed

Answer 1

-400 Turbulent air penetration speed:
290 to 310 KIAS / 0.82 to 0.85 Mach, whichever is lower

-8 Severe turbulent air penetration speed:
310KIAS / .83M, whichever is lower

Question 2

Maximum Takeoff and Landing Tailwind Component

Answer 2

15 knots
LCF: 10KTS

Question 3

Weather radar limitation

Answer 3

Avoid weather radar operation in a hangar.
Note: The hangar recommendation does not apply to the weather radar test mode.

Question 4

Maximum speed operating in Reduced Vertical Separation Minimum (RVSM) Airspace

Answer 4

0.90 Mach

Question 5

Maximum allowable wind speeds when landing weather minima are predicted on autoland operations

Answer 5

Headwind 25 knots
Tailwind 15 knots (10 LCF)
Crosswind 25 knots
Crosswind CAT II/III 15 knots

Question 6

Maximum and Minimum glide slope angles for autoland operations

Answer 6

The maximum glideslope angle is 3.25 degrees.
The minimum glideslope angle is 2.5 degrees.

Question 7

Autoland flap limitations

Answer 7

Automatic landings may be made with flaps 25 or 30 only.

Question 8

FLCH mode limitation

Answer 8

Do not use FLCH on final approach below 1,000 feet AFE.

Question 9

AFDS limitation

Answer 9

Use of aileron trim with the autopilot engaged is prohibited.

Question 10

Autopilot altitude limitations

Answer 10

The autopilot must not be engaged below 250 feet after takeoff.

Without LAND 2 or LAND 3 annunciated, the autopilot must not remain engaged below 100 feet RA.

The autopilot must be disengaged before the airplane descends more than 50 feet below minimums unless it is coupled to an ILS glideslope and localizer or in the go-around mode.

Question 11

Reverse Thrust limitations

Answer 11

Intentional selection of reverse thrust in flight is prohibited.

Backing the airplane with use of reverse thrust is prohibited.

Question 12

Flight Control limitations

Answer 12

Avoid rapid and large alternating control inputs, especially in combination with large changes in pitch, roll, or yaw (e.g., large side slip angles) as they may result in structural failure at any speed, including below VA.

Question 13

Flap limitation

Answer 13

The maximum altitude with flaps extended is 20,000 feet.

Question 14

VNAV mode selection limitation

Answer 14

If leveling off within 2000 feet after changing altimeter setting from QNE to QNH, or QNH to QNE, do not use VNAV to execute the level-off if QNH is less than 29.70 IN/1006 hPa. After the level-off is complete, VNAV may be re-engaged.
