Single engine Class B aircraft must have a Vr that is not less than …

Class A Vr must not be less than … and …

Vmcg
Vmcg is the minimum CAS in the t/o run at which …
Max lateral deviation from the centreline must not exceed …
on failure of the critical engine with the remaining engine at max t/o thrust the pilot can retain control of the aircraft using primary aerodynamic forces alone

is Vmc the same as Vmcg or Vmca?
Vmca
When operating at Vmc after an engine failure up to … degrees of bank … as well as … may be used to help keep the aircraft straight
it must not be necessary to …

reduce power or thrust of the operative engines to maintain control
20 degrees
Because the 5 degrees of bank cannot be immediately applied at Vlof (due to the proximity to the ground) a factor is added to Vr to allow for the absence of 5 degrees of bank if the critical engine were to fail at rotation.
The restriction is … to enable adequate controllability with the wings level and an engine out at Vlof
Vr must be higher than 1.05 Vmc
Vmc may not exceed … Vsr

Vmc increases as air density increases and is highest at low pressure altitudes, low temperatures and low humidity, because …
this is where the asymmetric thrust is greatest
(operative engine producing greatest thrust with largest density)
Because the tyres are limited by a true groundspeed and Vr is an airspeed, tyre limit graphs are affected by … and …
pressure altitude and temp
Tyre speeds are most likely to be limiting where the TAS is highest and where the groundspeeds are highest, which would be …

at high temps, high pressure altitudes and with tailwinds
Compared to a flapless setting using a little bit of flap increases CLmax and reduces …
The extra increase in aerodynamic drag has minimal effect on acceleration so this allows the aircraft to … and reduces …

best climb gradient comes from the …, where the gap between … is greatest

minimum climb gradients after t/o
A compromise between field length and obstacle clearance has to be reached. Looking at the graph comparing t/o mass with flap setting, considering both climb gradient and field length the optimum setting can be found where the two lines intersect
Increasing flap setting up to the optimum decreases … (4 points)
Reducing flap setting from optimum increases the above points and decreases ….
