The next critical thing we need for landing particularly is the Gear 😳🤭 Whilst this doesnt have GEAR written on the lever it is actually shaped like a wheel and has on this version the very groves that also appear as tread on the actual tyres. Cool use of symbology. #Avgeek
On this @BoeingAirplanes 747 the speed brake is on the left of the thrust levers and is shaped like a handbrake lever that you may have had on an old car. This is used to increase drag inflight or to “dump” lift and aerodynamically brake on landing. #AvGeek #Aviation
In the unlikely event of an engine fire to assist pilots the switches for the fuel cutoff and fire extinguishers will light up bright red and in the case of the extinguishers will also have the number illuminated. Note the APU extinguisher handle is at 90 degrees to the engines
Almost every switch, lever, or handle that a pilot may have to move whilst inflight is shaped differently. Whether it be the external lights, radar controls, or the temperature control for the air conditioning, they are all subtly different. #AvGeek #Aviation
Why has this been done? In short, if the visibity in the flight deck is reduced at night or be other means, then we have the ability to be able to identify and use critical controls and those that we may routinely need. And of course it makes for an informative Twitter thread 😜
