VHF Omnidirectional Radio Range (VOR) is defined as VHF Omnidirectional Radio Range, an aircraft navigation system operating in the VHF band.
VOR's are assigned radio channels between 108.0 MHz and 117.95 MHz (with 50 kHz spacing); this is in the very high frequency (VHF) range.
Unload. Make sure you are no longer 'pulling G's'
Roll wings level
Power Reduce the power to avoid overspeeding.
gently pull back on the control wheel to ease out of the dive.
When slowed down to a safe airspeed apply throttle as needed.
(N.b.: Do not confuse a spiral dive with a spin)
In a high bypass design, the vast majority of the thrust is derived from the ducted fan, rather than from combustion gases expanding in a nozzle.
A high bypass ratio provides a lower thrust specific fuel consumption (grams/sec fuel per unit of thrust in kN using SI units), especially at zero velocity (at takeoff) and at the cruise speed of most commercial jet aircraft.
Swept wings are designed to be the most effective at high speeds. At low speeds, a swept wing produces less lift than its straight counterpart.
Mostly in the fan, but also from the exhaust nozzle duct.
Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.
A turbofan is a type of jet engine, similar to a turbojet.
It essentially consists of a ducted fan with a smaller diameter turbojet engine mounted behind it that powers the fan.
Part of the airstream from the ducted fan passes through the turbojet where it is burnt to power the fan, but the majority of the flow bypasses it, and produces most of the thrust. They are mainly used commercially because they are highly efficient and relatively quiet in operation.
-15°C
because:
-2°C per 1000 feet gives -30°C.
ISA: 15°C at sea level - 30°C = -15°C at FL150
Decreasing speed, by reducing engine power or pitching up.
High lift devices increase the lift produced by a wing, allowing the aircraft to operate at lower speed ranges usually for take off and landing.
