What sort of weather would you find at an occluded front?

What sort of weather would you find at an occluded front?

Low pressure weather, unstable weather.

How do you convert between lbs and kg?

How do you convert between lbs and kg?

1kg = 2.2lbs

How would you load an aircraft for max range?

How would you load an aircraft for max range?

The position of the CG directly influences the fuel consumption of an aircraft. An aft position of the CG makes the aircraft less stable, requiring less lift to be generated in both the horizontal stabilizer and wings, reducing the overall drag of the aircraft, and increasing the max range.

You want to load the the aircraft so that the CG is at, or as close as possible, to the aft limit (Without exceeding it).

What is BEM?

What is BEM?

Basic Empty Mass (BEM) is the mass of the aircraft with the basic equipment, unconsumable fluids and unusable fuel and oil.

How does an altimeter work and which errors can an altimeter experience?

How does an altimeter work and which errors can an altimeter experience?

When an aircraft climbs, the static pressure in the instrument case decreases, which allows the enclosed capsule to expand.

This in turn moves the needle on the instrument to indicate a corresponding altitude.

During descent, the opposite function applies.

Altimeter errors can originate and vary from:

Instrument Pressure Time-lag Barometric Density Temperature Blocked static port

Can a helicopter rotor blade stall?

Can a helicopter rotor blade stall?

Yes

How does GPWS work?

How does GPWS work?

GPWS is a central computer system that receives various data inputs on configuration, (radio altimeter) height/altitude and instrument landing system glide slope deviation and is able to alert the pilot when a dangerous situation is about to occur.

How can you calculate the Operating Mass?

How can you calculate the Operating Mass?

OM = DOM + crew and fuel

What is the speed of sound at sea level according to ISA?

What is the speed of sound at sea level according to ISA?

662 kts

Local speed of sound = 39 x √(Temperature in Kelvin)

15°C in Kelvin is (15 + 273) = 288

So the local speed of sound = 39 x √288 = 662 kts

What’s the temperature at FL150 according to ISA?

What’s the temperature at FL150 according to ISA?

-15°C

because:

-2°C per 1000 feet gives -30°C.

ISA: 15°C at sea level - 30°C = -15°C at FL150
