ADY -- Climbing Descending and Turning 2 Flashcards
If frost forms on the wings of an aircraft overnight and is not removed before flight …..
There will be less margin between the Vtoss and Vs
The recommended IAS to achieve the maximum angle of climb at sea level is 80kts for a particular aircraft. What will reduce the angle of climb?
A decrease in IAS or a tail wind
During an approach what is the effect of a sudden decrease in headwind component on IAS and rate of decent …..
IAS will decrease and rate of decent will increase
Partial extension of flap in a glide at constant IAS will result in …..
an increase in rate and angle of decent
The best angle of climb speed for a particular piston engine aircraft is 65kts IAS. What could reduce this best angle of climb …..
a decrease in IAS or a tail wind
A pilot assesses that he is undershooting the selected field while on final for a forced landing in nil wind at the best L/D ratio speed. The safest procedure to employ is to …..
maintain the present nose attitude and airspeed as there is no better than the best L/D ratio
Describe the effect of an increased headwind during a steady climb with constant IAS and constant power maintained …..
rate of climb remains the same but the angle of climb increases
The effect of fitting an aircraft with a more powerful engine would be most noticable during …..
a max rate climb
When manoeuvering at low level on a windy day the pilot should be aware of the following illusions …..
Slipping into a turn when turing from upwind to downwind
Skidding when turning from downwind to upwind
If nose attitude and power are kept constant, a sudden decrease in headwind during the final approach will initially cause …..
a decrease in IAS and an increase in the gliding range
Describe how increased weight effects the maximum gliding performance in nil wind …..
the speed for best gliding increases and the gliding distance remains the same
remember the picture of the black and white planes on the slope. The heavier one gets to the bottom faster but they both go the same distance in nil wind.
if angle of bank and IAS are kept constant, an increase in altitude will cause …..
an increase in the radius of the turn since the density is less the TAS must be higher when compared with the lower altitude turn
An effect of lowering full flap during a descent is to …..
increase both the lift and drag
If the headwind component suddenly decreased in a decent …..
IAS would decrease and rate of decent would increase
The IAS at which the stall occurs during a 75-degree banked level turn would increase over the level flight stalling speed by approximately ……
100%
remember that stall speed increase with the square root of the load factor. since the 75-degree turn is a load factor of 4 the square root is 2 so it is 2 times faster which is 100%
Relating to turn radius
2 planes identical in every respect except for gross weight, carry out a balanced level turn at the same IAS and anfle of bank. The heavier aeroplane will …..
the same radius of turn and the same rate of turn as the lighter one
What will be the effect on turning performance if IAS is increased during a level turn at a constant bank ….
the rate of turn decreases and the radius of the turn increases
The angle of bank required to perform a rate one turn at a TAS of 180kts is closest to ….
250
During a steady descent at a constant IAS thrust is …..
less than drag
During a glide forced landing the pilot is maintaing the best L/D ratio but realises he is undershooting. The best course of action would be to …..
maintain the current decent attitude to acheve max gliding distance.
Take what you get at best L/D since there is no better
The limit to the rate of turn that can be acherved by a typical GA aircraft is governed by …..
the amount of power available from the engine
The load factor at high angles of bank are accompanied by a dramatic increase in drag as well as the stalling speed. This must be over come by applying extra power but a light aircraft runs out of power and can no longer maintain the speed at or beyond the stalling angle.
The load factor limit is most likely to be exceeded during a level turn if the angle of bank is ….. at a speed ……
increased, Va
Abrupt control movements are likely to impose excessive stresses on the airframe if they are made above …..
Vno
If power is increased during a turn while maintaining the stalling angle of bank what happens to the radius and rrate of turn …..
Radius of turn will remain the same and the rate of turn will increase.
Remember if the angle of bank remains the same then the radius of the turn will stay the same.
If power is introduced then the turn will be completed faster so the rate of turn will increase.
