2016 PC Guide - Taxi-in

Question 1

Master Caution Light

After landing, during taxi in, a MASTER CAUTION light comes on, but is promptly reset without noting the specific cause.

Is this the proper procedure?

What important malfunction could be missed?

Answer 1

No, this is not the proper procedure. All MASTER CAUTION lights should be investigated, no matter what phase of flight.

An ENGINE CONTROL (NG only) light (which only occurs on the ground and with the engine operating) could be missed, potentially causing a significant delay on the next flight.

Question 2

Tail Drift

In the gate area, a 90 degree turn into the gate is required. You decide to lead the turn, with your nose with your nose gear aligning on the J-line just before the Ramp Agent stops your aircraft.

Is this the proper procedure?

What might result in this case?

Answer 2

This is not the correct procedure. Align the aircraft properly from the top of the J-line. Otherwise, a “tail drift” could result and the entire aircraft might not be inside the safety area at shut down.

Question 3

Flap Speed Exceedance

After engine shutdown, you get an FMS message (NG only) stating a flap 30 limit was exceeded, max speed 174.8. What must you do now?

Answer 3

You must write up the flap exceedance in the logbook. Notify Dispatch and Maintenance Control.

Question 4

Flap Speed Exceedance

You contact Maintenance Control to notify them of a flap 30 speed exceedance of 174.8. Maintenance Control says to document the exceedance using an “Info Only” logbook entry. Is this OK?

Answer 4

An “info Only” write up for any flap overspeed is not correct.
