How to Manage Speed in a 737 (Simple Guide)

Last updated: May 2026

Speed management is one of the biggest challenges when flying the 737 in MSFS — and it’s also one of the most important.

Get this right, and everything becomes easier.

Get it wrong, and you’ll constantly feel behind the aircraft.

Why Speed Matters So Much

In the 737:

• Speed controls your descent
• Speed affects flap usage
• Speed determines stability

You’re always balancing speed with aircraft configuration.

Basic Speed Flow

Here’s a simple version that works almost every time.

Cruise

• Mach .78–.80

Descent

• Around 280 knots
• Then reduce to 250 knots below 10,000 feet

Approach

• 210 knots (initial)
• 180 knots (gear down)
• Final approach speed (VREF + additives)

Using Flaps to Control Speed

Flaps are your best friend.

Typical flow:

• Flaps 1: slow to around 230 knots
• Flaps 5: around 210 knots
• Flaps 10–15: further reduction
• Gear down: adds drag quickly

Use Speed Brakes When Needed

If you’re too fast or too high:

• Deploy speed brakes
• Don’t rely on them constantly
• Retract before landing

Autopilot Speed Modes

The 737 gives you:

• VNAV: manages speed automatically
• MCP speed: manual control
• Speed intervention: override VNAV

Learn to use all three.

Common Mistakes

• Staying too fast too long
• Dropping flaps too late
• Ignoring speed restrictions
• Not planning ahead

Final Tip

Always think one step ahead of the aircraft.

If you wait until you “need” to slow down, you’re already late.

Managing speed in the 737 is about planning, using flaps correctly, and keeping the aircraft under control at every stage of flight.
