Core Features of the Boeing 737 MAX Simulation

High-quality simulations of the 737 MAX replicate the aircraft's physical and electronic systems with remarkable fidelity. The following features distinguish the MAX simulation from older 737 variants and other airliners.

Advanced Cockpit and Avionics

The simulation cockpit includes a detailed replica of the MAX's unique instrument panel. The most prominent change from the 737 Next Generation is the addition of the Flight Dynamics Control Display (FDCD) and the Vertical Situation Display (VSD). The primary flight display (PFD) and navigation display (ND) are fully functional, showing synthetic vision on some platforms. Autopilot modes such as LNAV, VNAV, CWS, and TOGA are accurately modeled. The multi-function control display unit (MCDU) allows full flight planning, performance calculations, and system monitoring. Pay close attention to the Manual Fuel System and Load Control System (LCS) panels, which are essential for managing fuel distribution and center tank pumps.

Fly-by-Wire System with New Trim Logic

The 737 MAX introduces a limited fly-by-wire control system for the elevators and ailerons, with a focus on stability augmentation and protection against excessive pitch-up during missed approaches. The simulation models the Control Wheel Steering (CWS) and the Speed Trim System (STS) accurately. You will notice that the MAX does not have manual reversion for the elevators; instead, the system uses the stabilizer trim to provide pitch control in manual reversion mode. Understanding the trim logic is crucial: the stabilizer trim wheel moves slowly and requires anticipation. Unlike the NG, the MAX trim wheel moves in the same direction as the yoke movement for pitch trim, which can be disorienting at first. Practice trimming with the electric trim switches on the yoke and monitor the stabilizer position indicator on the upper EICAS display.

Engine and Performance Modeling

The simulation replicates the CFM International LEAP-1B engines, which are larger and more efficient than the NG's CFM56s. The Engine Instrument System (EIS) displays N1, N2, EGT, and fuel flow with realistic lag. The MAX's automatic thrust restoration system (ATR) and auto-throttle logic are faithfully represented. You can expect accurate fuel consumption figures—the MAX burns approximately 2,500–2,800 kg per hour during cruise, depending on weight and altitude. Performance calculations for takeoff thrust settings, V-speeds, and max altitude are integrated into the MCDU. Use the THR REF page to set takeoff derates (TO-1, TO-2) and calculate flexible thrust. The simulation also models the MAX's enlarged nacelles and chevrons, which affect drag and noise profiles.

Environmental and Weather Systems

Realistic weather integration is a hallmark of modern flight simulation. The 737 MAX simulation incorporates turbulence, wind shear (including the MAX's wind shear detection and escape guidance), icing conditions (with anti-ice systems on wing and engine cowls), and enhanced wake turbulence effects. The weather radar, displayed on the ND, shows actual storm cells with gain control and tilt management. Active Sky and built-in live weather engines (e.g., in MSFS) provide real-world weather patterns. Knowing how to interpret the radar and adjust settings reduces risk during severe weather encounters in the sim.

Systems Depth

Beyond flight controls and engines, the simulation models hydraulics (three systems: A, B, and a standby), electrical (two generators, APU, battery, and external power), pneumatic (bleed air from engines and APU for pressurization and anti-ice), and environmental control (ECS) with dual packs and recirculation fans. Failure modes—such as hydraulic leak, generator failure, or pressurization issues—are available in many add-ons and test your troubleshooting skills. The MAX's new Cabin Crew Alerting System (CCAS) and Maintenance Communication System (MCS) are simulated in some high-fidelity packages, adding operational realism.

Mastering Flight Handling: Tips and Techniques

The 737 MAX handles differently from its predecessors due to its larger engines located further forward on the wing, which creates a more pronounced pitch-up tendency at high thrust settings. Additionally, the fly-by-wire logic influences control feel, especially during manual flight. The following sections provide practical tips for each phase of flight.

Pre-Flight Preparation Deep Dive

  • Flight Plan and Performance Setup: Load your flight plan into the MCDU, including SIDs, STARs, and waypoints. Use the INIT REF page to enter fuel weight, zero fuel weight (ZFW), and maximum landing weight (MLW). Calculate takeoff V-speeds (V1, VR, V2) based on the actual weight and temperature. Do not forget to set the Takeoff Configuration Warning (TOW) on the overhead panel.
  • Systems Configuration: Complete the flows: landing gear down, flaps set to 1 or 5 (depending on weight), speedbrake armed, auto-brake set (typically RTO for takeoff), and flight directors on. Verify all annunciators are off or normal. Use the Status Page on the MCDU to review system pages like HYD, ELEC, and PRESS.
  • Flight Control Check: Move the yoke fully left and right, then fully forward and aft, while watching the control surface indications on the TRA page (if available). Check that the stabilizer trim moves freely in both directions using the electric trim switches.
  • Weather Briefing: Review the weather at departure, enroute, and arrival airports. Update the route if significant wind shifts are present. Enter ISA deviation and wind data into the MCDU PERF page.

Takeoff Procedures and Considerations

  • Throttle Application: Unlike older 737s, the MAX requires a smooth, deliberate advance of the thrust levers to 40% N1 before engaging the TO/GA button. This avoids abrupt engine spool-up and minimizes pitch-up. Once TO/GA is active, the auto-throttle will advance to the selected thrust setting (TO-1 or TO-2).
  • Rotation Technique: At V1, maintain forward pressure on the yoke. At VR, rotate smoothly at 2.5–3 degrees per second to a pitch attitude of about 15 degrees. The MAX's pitch-up moment is stronger; be prepared to increase forward yoke pressure to avoid over-rotation. The flight director may command a pitch target—follow it but be ready to override if the aircraft wants to pitch too high.
  • Initial Climb: After liftoff, at a positive rate of climb, raise the gear. Engage the autopilot at 400 feet AGL if desired, but manual flying to 1,000 feet is recommended for practice. Retract flaps on schedule (1 at acceleration altitude, 5 at clean speed). Use VNAV for speed control, but monitor for excessive pitch excursions due to weight.

In-Flight Handling and Automation Management

  • Pitch and Bank Control: In manual flight, the MAX feels well-damped but heavy in pitch. Avoid large control inputs—center the yoke and allow the aircraft to stabilize. For turns, use 25 degrees of bank as a maximum in normal operations (except for emergency avoidance). The fly-by-wire provides positive spiral stability, so you can release the yoke briefly to regain orientation.
  • Trim Management: Trim is critical. After leveling off at cruising altitude, adjust the stabilizer trim to remove any control column forces. Fly with a neutral force column; the yoke should feel light. Use the electric trim switches in short bursts—hold for no more than one second per activation—to avoid over-trimming.
  • Autopilot Modes: Use LNAV and VNAV for route and profile navigation. For altitude changes, select FLCH (flight level change) with a target altitude, and let the autothrottle manage thrust. For approaches, engage VOR/LOC or APP modes early, and verify the correct capture. The MAX's autopilot is highly capable but watch for mode changes during complex SIDs and STARs.
  • Fuel Management: During cruise, monitor fuel in the center tank. When center tank quantity reaches about 1,000 kg, transfer fuel to the wing tanks using the LCS. Do not forget to close the center tank fuel pump switches after transfer to avoid pump cavitation.

Approach and Landing Techniques

  • Preparation: Set up the approach as early as possible: tune the ILS frequency or set GPS approach. Enter approach minima and press the VOR/LOC and APP buttons. Reduce speed to 220 knots before the initial approach fix, and configure flaps on the schedule (typically 1 at 210 knots, 5 at 190, 15 at 170, 25 at 160, 30 at 150). Extend landing gear at approximately 5 NM from the runway and during the final stage.
  • Manual Landing: For a manual landing, disconnect the autopilot at 500–800 feet AGL. Fly the glideslope and localizer manually. The MAX's low-drag design requires careful speed management—aim for Vref +5 knots (typically 130–140 knots) over the threshold. Flare gently at 20 feet, reducing thrust to idle as you round out. Hold the nose wheel off as long as possible. The MAX's large engines can cause a floating effect if speed is high; use a firm but gentle touchdown.
  • Autoland: The MAX simulation supports autoland with the use of dual autopilots (CMD A and CMD B). Activate both before the outer marker. At 50 feet, the autopilot will initiate flare and then lock onto the localizer/glideslope until touchdown. Monitor the airplane carefully—if the autoland fails, take control immediately.
  • Go-Around: If a go-around is needed, engage TO/GA. The flight director will command a pitch-up to 15 degrees. Retract flaps from 30 to 15 (or 25 to 15) upon positive rate. Do not retract landing gear immediately—wait until you have a positive climb and are clear of obstacles. The MAX's go-around performance is powerful, but the pitch-up can be aggressive; be ready to counteract with forward yoke.

Common Pitfalls and How to Avoid Them

  • Over-reliance on Automation: Even in the sim, it's easy to let the autopilot do everything. Practice manual flying during climb and descent to maintain proficiency. Use autopilot for long cruise segments, but hand-fly the approach when weather permits.
  • Incorrect Trim Usage: Many simmers trim with long presses, causing rapid trim wheel movement and oscillation. Use short, precise trim inputs and wait for the aircraft to respond. Monitor the stabilizer position indicator.
  • Pitch Attitude Cues: New pilots often focus too much on the attitude indicator and not enough on the flight director and VSI. During rotation, cross-check pitch with airspeed and vertical speed. The MAX's pitch limits are different from the NG—do not exceed 20 degrees nose-up during initial climb.
  • Fuel Mismanagement: Forgetting to transfer fuel from the center tank leads to an unbalance or fuel starvation. Program a checklist for the LCS transfer at cruise phase.
  • Incorrect Flap Speeds: Exceeding flap placard speeds can cause damage in the sim (or at least trigger warnings). Know the maximum speeds: Flaps 1: 250 knots, Flaps 5: 230, Flaps 10: 200, Flaps 15: 190, Flaps 25: 180, Flaps 30: 170. Keep speeds at or below these values.
