737 MAX Flight Crew Operations Manual
Warning Systems -
System Description
15.20.6 MN-FLT-OH-201
Red light illuminated –
• landing gear is in disagreement with LANDING GEAR lever position
(in transit or unsafe).
• landing gear is not down and locked (with either or both forward thrust
levers retarded to idle, and below 800 feet AGL).
All lights extinguished – landing gear is up and locked with the LANDING GEAR
lever UP.
Aural Indications
A steady warning horn is provided to alert the flight crew whenever a landing is
attempted and any gear is not down and locked. The landing gear warning horn is
activated by forward thrust lever and flap position as follows:
Flaps up through 10 –
• altitude below 800 feet RA, when either forward thrust lever set
between idle and approximately 20 degrees thrust lever angle, or an
engine is not operating and the other thrust lever is less than 34 degrees.
The landing gear warning horn can be silenced (reset) with the landing
gear warning HORN CUTOUT switch
• if the airplane descends below 200 feet RA, the warning horn cannot be
silenced by the warning HORN CUTOUT switch.
Flaps 15 through 25 –
• either forward thrust lever set below approximately 20 degrees, or an
engine not operating and the other thrust lever is less than 34 degrees.
The landing gear warning horn cannot be silenced with the landing gear
warning HORN CUTOUT switch.
Flaps greater than 25 –
• regardless of forward thrust lever position. The landing gear warning
horn cannot be silenced with the landing gear warning HORN
CUTOUT switch.
The warning indication is canceled when the configuration error is corrected.
Mach/Airspeed Warning System
Two independent Mach/airspeed warning systems provide a distinct aural
warning, a clacker, any time the maximum operating airspeed of Vmo/Mmo is
exceeded. The warning clackers can be silenced only by reducing airspeed below
Vmo/Mmo.
The airspeed indicator displays red and black warning bands indicating maximum
and minimum allowable airspeeds. The ends of the amber bands indicate
maximum and minimum maneuver speeds.
