===== Boeing 737-500 =====

{{:wiki:737.jpg?450|}}

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:[[aircraft:universal_uns1_fms|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**
