Boeing 737-500

The Boeing 737 series is the world's most popular aircraft family. The shortened B737-500 variant has a capacity of a maximum of 140 people. The specific B737-500 modeled in Aerofly FS 2 is based on an aircraft with the classic “steam gauge” cockpit, retrofit high-bypass CFM56 engines for better fuel economy and retrofit cockpit devices such as a Universal FMS to allow modern navigation.

Flight Plan Editing in the CDU

The flight management system of the exact 737-500 that we are simulating is a retrofit and therefor is identical to the ones found in the Learjet 45 and Q400. The interface to the flight management system (FMS) is called a control display unit (CDU). The CDU is the device that pilot interact with in the cockpit, the computers performing all the calculations are called flight management computers (FMC).

We added a tutorial on how to create a flight plan in the 737, Learjet 45 and Q400:Universal UNS-1

Flight Notes

Speed, Height, Distance Conversion

  • Level flight deceleration allow 10kts/nm & 1kt/sec (deceleration is faster at lower weights)
  • Descending deceleration allow 5kts/nm & 0.5kt/sec
  • Idle descent allow 3nm/1000'

Approach Profile Planning

  • Aim for 250kts, 10,000ft by 30nm out
  • Aim for 210kts, On ILS at 12nm

Cruise N1

  • N1 = (2 x Alt/1000) + 10   eg at FL350 = 70+10 = 80% N1 or FF = (IAS*10)/2 -200  eg 250kts = 2500/2 -200 = 1050 kg/hr/engine

Climb Speeds

If ECON info not available, use 250KIAS until 10,000ft then 280KIAS/M0.74 thereafter

  • Best Angle = V2 + 80
  • Best Rate = V2 + 120
