What % above stall speed is VR?
For safety reasons VR is 20% above stall speed, which gives safe margin for error ( VR is usually determined as being 1.2 × VSTALL )
What margin would you add to your take off performance calculations for a dry grass runway with a 2% upslope?
correct answer is 63% or 1.63 1.33 or 33% recommended additional safety factor for take off, plus 10% or 1.10 for a 2% upslope and 20% or 1.20 for dry grass.
Your engine has stopped at 450ft after take off with no runway remaining, what should your first thought be?
Always remember to fly the aircraft first. Your first instinct should be to immediately lower the nose to prevent a stall occurring.
You have a fully loaded aircraft with enough fuel to perform your trip and have a reserve, however your mass and balance calculations have shown the aircraft is just beyond the forward CG limit. What should your actions be?
If the aircraft is outside of the CG envelope you should not take off regardless of the take off weight
