What will happen if the primer of your engine/fuel system kept operating?
What will happen if the primer of your engine/fuel system kept operating?
A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage, fixed pitch propellers only have a certain rpm.
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’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
What is the range of a VOR at 32000ft?
What is the range of a VOR at 32000ft?
Range = 1.23(√H1 + √H2)
= 1.23 * √32000
= 220 nm
You are flying in a straight line on an airway when your company calls and requests you to return to base, what will you do first?

Inform ATC.
Some wings, flaps and rudders are indented, why?
Some wings, flaps and rudders are indented, why?
To increase the strength of the surfaces.
The same strategy is employed by plastic water bottles, by adding ridges to a surface you increase it's structural rigidity
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.
What is the height of the tropopause according to ISA?
What is the height of the tropopause according to ISA?
36,090ft in ISA
Why is a great circle the shortest distance between two points?
Why is a great circle the shortest distance between two points?
The track changes constantly.
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.
