Approach, landing considerations

Question 1

When should a pilot perform the Before Top of Descent Tasks?

Answer 1

50 NM before TOD or 150 NM from destination.

Question 2

Describe the touchdown zone.

Answer 2

The area of the runway 500 ft. to 3,000 ft. beyond the landing threshold not to exceed the first one-third of the runway. Do not confuse the planned point of touchdown (1,000 ft. to 1,500 ft. from the landing threshold) with the TDZ. The impact to landing performance must be considered for any touchdown past 1,500 ft. from the landing threshold

Question 3

What is the last point you can initiate a go around?

Answer 3

A go around is possible until the thrust reverser levers are raised.

Question 4

What stabilized approach criteria must be met by 1,000 ft. above TDZE?

Answer 4

• In the planned landing configuration
• In the Target speed range
• On an appropriate glide path with a normal descent rate
• For approaches where maneuvering is required, wings essentially are level on centerline by 500 ft. above TDZE

Question 5

What is the Pilot Monitoring responsibility in the event of an unstabilized approach?

Answer 5

It is the duty and responsibility of any Flight Deck Crew Member to execute or direct a go-around/missed approach when stabilized approach criteria are not met.

Question 6

You are flying from PHX to SAN and have received your PWB Landing Data. Your stopping margin is AB2-500, AB3-1500, ABM-2000.

What is the runway usable length if landing on RWY 27?

Answer 6

7,591 ft

Question 7

You are flying from PHX to SAN and have received your PWB Landing Data. Your stopping margin is AB2-500, AB3-1500, ABM-2000.

Which is the limiting factor if AB2 were selected, the PWB stopping margin or the Touchdown Zone?

Answer 7

The PWB stopping margin added to the last planned point of touchdown (1,500’+500’=2,000’) would be more limiting than the Touchdown Zone (7,591’/3=2,530’).

Question 8

You are flying from PHX to SAN and have received your PWB Landing Data. Your stopping margin is AB2-500, AB3-1500, ABM-2000.

What manual braking technique is used to approximate autobrake 2?

Answer 8

Minimum braking (autobrake 2) can be approximated by accomplishing a normal landing using spoilers and reverse thrust, with light manual braking initiated at approximately 80 kts.

Note: Any time the Min (2) stopping margin is negative (dashes), begin manual braking immediately after nose wheel touchdown.

Question 9

You are flying from PHX to SAN and have received your PWB Landing Data. Your stopping margin is AB2-500, AB3-1500, ABM-2000.

Which is the limiting factor if AB3 were selected, the PWB stopping margin or the Touchdown Zone?

Answer 9

The Touchdown Zone (7,591’/3=2,530’) is more limiting than the PWB stopping margin added to the last planned point of touchdown (1,500’+1,500’=3,000’).

Question 10

You are flying from PHX to SAN and have received your PWB Landing Data. Your stopping margin is AB2-500, AB3-1500, ABM-2000.

When is a go-around required with regard to point of landing on the runway?

Answer 10

• A landing in the touchdown zone cannot be safely accomplished.
• The aircraft touches down beyond 1,500 ft. with an insufficient PWB System-computed stopping margin.
