the panel, you can select the last flap setting that you want to be called based on the airspeed by selecting the corresponding option. The remaining flap calls will be based on the airspeed above, but will occur at the latest when passing the altitudes entered in the table on the lower left of the panel. The number of rows in the table will automatically be updated based on your selection.

If we study the 737 again, the Flap 15 call is the last one that is made based on the indicated air speed alone. Thus, the option beneath the F15 column is selected. The rest of the flap calls—Flap 25, Flap 30, and Flap 40—are made based on both the speed and the aircraft’s altitude. The flap calls will therefore occur at the latest when the specified altitude is reached.
Note! This functionality ensures that you don’t fly your aircraft at low speeds or at low altitudes without extending the flaps to the required position. The call is made as the indicated air speed drops below the specified speed or when the aircraft passes the specified altitude, whichever comes first.
