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
What is the angle of incidence?
What is the angle of incidence?
The angle between between the chord line and the aircraft's longitudinal axis. It's a fixed angle for wings, but variable for variable incidence tailplanes.
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)

What is the height of the tropopause according to ISA?
What is the height of the tropopause according to ISA?
36,090ft in ISA
What is tire creep, and is it important?
What is tire creep, and is it important?
Tire creep is the tendency of the tire to rotate slowly around the wheel hub as a result of a millisecond landing friction on the tire before wheel spin occurs.
Yes, it is important because if there is too much creep the tire can tear out the inflation valve and cause the tire to burst.
What clearance do MSA values give?
What clearance do MSA values give?
They provide at least 1000ft clearance over obstacles within 25NM of the homing facility.
What would you do in the event of an engine failure below V1, and what would your initial actions be?
What would you do in the event of an engine failure below V1, and what would your initial actions be?
Assuming I'm performing single pilot operations:
-
power idle,
-
max brakes (and reversers if available),
-maintain directional control using rudder input,
-
After coming to a full stop set parking break.
-
Inform ATC 'Stopping'.
-
Initiate the appropriate process to diagnose the problem (ECAM, NITS DODAR, checklists....).
-
When performing multi pilot operations the actions performed by me will depend with my current role: PF, PM and/or CM1 CM2.
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.
Why do jet aircraft fly as high and fast as possible?
Why do jet aircraft fly as high and fast as possible?
Because the air is less dense thus the TAS is higher for a given power setting and for this reason modern jet aircraft are designed to be most efficient at high altitude.
