737 Limitations

Question 1

Max operating pressure altitude

Answer 1

41,000 feet

Question 2

Maximum takeoff/landing tailwind component

Answer 2

15 knots

Question 3

Recommended severe turbulence penetration speed
Cruise:
Climb and descent:

Answer 3

Cruise: TURB N1 setting from cruise page
Climb and descent: 280 knots/.76 Mach

Note: if severe turbulence is encountered below 15,000’ and a/c gross weight less than max landing weight, a/c may be slowed to 250kts in clean configuration

Question 4

Recommended crosswind component guidelines (knots)

RCC 6 takeoff? RCC5 takeoff?

Answer 4

RCC6: 33
RCC5: 25

Split scimitar winglet

(Split scimitar winglet assumes an engine failure RTO)

Question 5

Recommended crosswind component guidelines (knots)

RCC 6 landing? RCC5 landing?

Answer 5

RCC6 landing: 37
RCC5 landing: 37

Split scimitar winglet

Split scimitar winglet:

• reduce landing x-wind guidelines by 5 knots on wet or contaminated runways when asymmetric thrust is used.
• winds measured at 33’ tower height and apply for runways 100’ or greater in width
• landing on untreated ice or snow should only be attempted when no melting is present

Question 6

Icing conditions on the ground

Answer 6

OAT 10°C or below

(And visible moisture in any form is present or vis 1 mile or less)
(Or on ground when snow, standing water, etc. can be ingested by engines, freeze on engines, nacelles, or engine sensor probes)

(**For s.e. taxi can have #2 eng heat on (iso valve closed separates system for the #1 start off APU. Don’t try to start #1 eng w/wing heat on… it will hang (book says 2-eng taxi out when WAI req.)

Question 7

Icing conditions in flight

Answer 7

TAT 10°C or below

And visible moisture present 1 mile or less vis

Question 8

Autopilot minimum engagement height (takeoff or missed approach)

Answer 8

400’ AGL

Pelysys says 800’

Question 9

Autopilot minimum altitude on approach:

• ILS/GLS coupled approach (no auto land)
• Non-Precision approach

Answer 9

• 50’ AGL
• 50’ below MDA/DA

(Autopilot must be disconnected below 500’ AGL without a published DA or MDA)

Question 10

Can you use LVL CHG on final approach below 1000’ AFE?

Answer 10

No

Question 11

Max flap extension altitude

Answer 11

20,000’

Question 12

(Pelesys)
Autoland - Maximum winds

Headwind:
Crosswind:
Tailwind (flaps 30 and 40):

Answer 12

Headwind: 25
Crosswind: 15
Tailwind (flaps 30 and 40): 10

737-900 (aircraft 401-412) landing at flaps 30:
Field elevation 4,000’ or less: 10
Field elevation 4,001’-6,000’: 5
Field elevation 6,001’ and up: 0

Question 13

In flight do not extend speed brake lever beyond ARMED detention with which flap setting selected?

Answer 13

Flaps 40°
