Approach category speeds are defined by which formula?

Approach category speeds are defined by which formula?

This speed is defined to be equal to the greater of stall speed (Vso) multiplied by 1.3, or stall speed (Vs1g) multiplied by 1.23.

The landing configuration that is to be taken into consideration can be defined by either the operator or by the aeroplane manufacturer but is most commonly assigned by the manufacturer.

What is anhedral?

What is anhedral?

anhedral is the downward inclinitation of the wing from the root to the tip.

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 are the advantages of fuel injection vs a carburetor?

What are the advantages of fuel injection vs a carburetor?

Fuel injection provides:

  • Fuel free from vaporization ice

  • Better economy through metered delivery

  • More responsive and efficient engine

  • Less maintenance

If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?

If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?

False glide slope.

Is the landing gear in the Seneca electrically or hydraulically operated?

Is the landing gear in the Seneca electrically or hydraulically operated?

What is radiation fog?

What is radiation fog?

Radiation fog forms on cloudless nights with only very light winds and high relative humidity when the cold ground cools the air above it to its dew point causing condensation (fog).

Usually occurs inland in valleys and low lying areas (as these areas tend to have more moisture) and usually occurs in a high pressure system.

What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?

What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?

Asymmetric Committal Altitude/Height is the minimum height needed to establish a positive climb whilst maintaining adequate speed for control and removal of drag during an approach to a landing.

In the Seneca at Oxford we used 200ft AGL. At this altitude when continuing for landing you selected the landing flaps (check clear runway, on speed, on altitude, landing clearance received).

You now are committed to land, single engine G/A with flaps 40 and gear down is not possible in a Seneca.

What is the movement of the center of pressure during/approaching a stall?

What is the movement of the center of pressure during/approaching a stall?

Center of pressure moves forward when approaching a stall.

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)
