How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?

How does the all moving stabilator work on the Boeing 737 compared a fixed horizontal stabilizer of, for example, the Seneca?

A moving stabilator allows for wider operating range of the control surface, which is of great importance in aircraft with a large range of operating speeds.

Compared to a fixed horizontal stabilizer, when trimmed, the moving stabilitor will produce less drag, reducing fuel consumption.

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 environmental lapse rate according to ISA?

What is the environmental lapse rate according to ISA?

1.98°C per 1000ft

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

While climbing with a SEP, in what temperature range can carb icing occur?

While climbing with a SEP, in what temperature range can carb icing occur?

Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.

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.

Why don’t you use carburetor heat on the ground for long periods?

Why don’t you use carburetor heat on the ground for long periods?

Battery power to the starter motors.

If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?

If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?

In Newfoundland. With cold weather density increases, therefore you would pick up a higher mass in Newfoundland.
