Virtually all modern airliners now use glass cockpits, old mechanical instruments are replaced with computer screens. This helps the pilots a great deal as less room is needed for all the dials. In the original 747 series there were 3 crew, 2 were pilots and one was the engineer who watched a huge bank of dials. In the new series there are just the 2 crew, and computers monitor the engines.

Here the airspeed indicator, artificial horizon and altimeter are all together. The airspeed and altitude are shown on 'tapes' rather than dials. The "M=0.38" indicates the Mach number, so M=1.00 would be the speed of sound. The red'bug' on the altimeter indicates the altitude minimums, do not go below...., and is set via the radio altimeter. See the supplemental instruments section. |

Our compass is combined with the VSi on the right.The bottom right dial alters the air pressure setting seen below the altimeter. There is a digital readout of the current heading in white (274) and the radial for the N2 nav aid in yellow (306) |

This is a moving map display showing airports (ie, Blackbushe), and nav aids (round symbols). The little squares reprersent other aircraft in your area and can be turned off in the TCAS button. The green splodge to the left is an area of poor weather such as heavy rain or a storm and can be turned off using the wxr button. You can zoom in to 15 and 7 miles when the screen becomes too cluttered using the z- and z+ buttons |

This is a multi function display showing various aspects of the aircraft. ENGN - Engine power settings FUEL - shows rate of fuel flow, amount left, etc FCON - Flight Control systems. Shows when flaps and speedbrakes are in use HYDR - Hydraulics FAIL - Failures. Shows when a component (engine, brakes, etc) has failed |

The top screen is a Global Positioning System (GPS) display. Using the SCL and DGT dials you can select airports and nav aids and the dislay will show the data on that location. IE, London Heathrow (ICAO code EGLL) is on a bearing of 294 degrees from us, 3 nautical miles away. Our ground speed is 252 knots and we are 1 minute away. Having a GPS means we only have 1 nav radio which also works the ILS glidescope. The GPS acts as N1, so clicking the N1 select on the autopilot will take us direct to whatever is selected. |

The flap handle is prominent with 'flap' written on it (Custom Heavy version). The slats operate automatically when you add flaps. The SBRK is a speedbrake to slow the aircraft down. 747's have 4 engines, so there are 4 sets of engine controls |
