Why is there an over boost protection on the Piper PA34 Seneca?
Why is there an over boost protection on the Piper PA34 Seneca?
To protect the engine from blowing up as it is easy to open the throttles to far during take off at sea level.
What do you prefer, a high or low wingload?
What do you prefer, a high or low wingload?
The assessor was trying to get to the approach where you need flaps and slats to increase S (lower wingload) in order to be able to fly a lower speed.
What is a VOR? What frequency range and band is it in?
What is a VOR? What frequency range and band is it in?
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.
Are swept wings effective?
Are swept wings effective?
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.
What is a turbo fan?
What is a turbo fan?
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.
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
5000 litres
(4 tonnes / 0.8 = 5000 litters)
Why do we calculate mass and balance?
Why do we calculate mass and balance?
To be within aircraft design limitations with regards to:
Structural limitations
Stability
Take-off and landing performance
What is VMBE?
What is VMBE?
The maximum brake energy speed.
It is a function of the gross weight, altitude, temperature, runway slope, wind component, and braking configuration.
V1 must be less than VMBE.
Can you explain what a coastal breeze is?
Can you explain what a coastal breeze is?
A coastal breeze is a wind from the sea that develops over land near coasts.
It is formed by increasing temperature differences between the land and water; these create a pressure minimum over the land due to its relative warmth, and forces higher pressure, cooler air from the sea to move inland.
Generally, air temperature gets cooler relative to nearby locations as one moves closer to a large body of water.
During what phase of flight is lift the greatest?
During what phase of flight is lift the greatest?
For a commerical aeroplane: During take off. At this point the aircraft has it it's maximum weight, and accelerating in the vertical plane requiring the highest ammount of lift to counteract the weight.
