What will be the effect on an aeroplane's performance if aerodrome pressure ?

Question 77-32 : It will decrease the take off distance required it will increase the take off distance required it will increase the take off ground run it will increase the accelerate stop distance

Admin .pressure altitude is the altitude displayed on an altimeter if you set 1013 hpa on the subscale your altimeter will show your pressure altitude above the 1013 hpa pressure level .if your pressure altitude is decreasing your actual altitude above that level will decrease too .lower altitude means denser air it means better performance and then it will decrease the take off distance required exemple 301 It will decrease the take-off distance required.It will decrease the take-off distance required.

What will be the influence on the aeroplane performance if aerodrome pressure ?

Question 77-33 : It will increase the take off distance it will decrease the take off distance it will increase the take off distance available it will decrease the take off run

Admin .pressure altitude is the altitude displayed on an altimeter if your pressure altitude indicated a high it means a reduced air density .air density has direct effect on lift drag engine performance when air density decreases aircraft performance decreases take off run will be increased exemple 305 It will increase the take-off distance.It will increase the take-off distance.

Which of the following distances will increase if you increase v1 but vr ?

Question 77-34 : Accelerate stop distance take off distance all engine take off distance take off run

Admin .accelerated stop distance is the distance required to accelerate to v1 with all engines at takeoff power experience an engine failure at v1 and abort the takeoff and bring the airplane to a stop using only braking action without the use of reverse thrust thus if you increase v1 the accelerate stop distance asd will increase .the decision speed at take off v1 is the calibrated airspeed below which take off must be rejected if an engine failure is recognized above which take off should be continued .vr remains unchanged and vr is the speed at which rotation to the lift off angle of attack is initiated so 'take off run' 'take off distance' and 'all engine take off distance' remain unchanged exemple 309 Accelerate stop distance.Accelerate stop distance.

Which of the following answers is true ?

Question 77-35 : V1 is lower or equal to vr v1 is higher vlof v1 is higher vr v1 is lower vmcg

Admin .v1 critical engine failure speed or decision speed engine failure below this speed should result in an aborted takeoff above this speed the takeoff run should be continued .vr speed at which the rotation of the airplane is initiated to takeoff attitude this speed cannot.be less than v1 or less than 1 05 x vmca minimum control speed in the air .vlof the speed at which the airplane first becomes airborne this is an engineering term used when the airplane is certificated and must meet certain requirements if it is not listed in the airplane flight manual it is within requirements and does not have to be taken into consideration by the pilot .vmcg the minimum control speed in the ground . 1459.note vmca minimum control speed in the air is located between v1 and vr exemple 313 V1 is lower or equal to vr.V1 is lower or equal to vr.

Question 77-37 : A downhill slope increases allowable take off mass an uphill slope increases the allowable take off mass allowable take off mass is not affected by runway slope a downhill slope decreases allowable take off mass

Admin .a downhill slope increases allowable take off mass .it will be easier to accelerate the aircraft assisted by the downhill component of weight therefore we can increase the mass and make 35 ft and v2 within toda however we will have to reduce v1 in case we have to stop with a heavier aircraft exemple 321 A downhill slope increases allowable take-off mass.A downhill slope increases allowable take-off mass.

Question 77-39 : Decreased tod required and increased field length limited tom increased tod required and decreased field length limited tom increased tod required and increased field length limited tom decreased tod required and decreased field length limited tom

Admin .a larger flap selection will permit to take off earlier but will decrease the path climb angle .if you have a weight limitation at take off due to the length of the runway by choosing a larger flap setting you will permit to reduce your take off run thus you can carry more weight exemple 329 Decreased tod required and increased field length limited tom.Decreased tod required and increased field length limited tom.

Question 77-40 : Vmca decreases with increasing pressure altitude vmca is not affected by pressure altitude vmca increases with increasing pressure altitude vmca decreases with pressure altitude higher than 4000 ft

Admin .vmc speeds are cas based it means they are not affected by the air density vmca is a controlling speed with one engine inoperative .as the altitude increases we get less asymmetric thrust therefore the controlling speed of vmca decreases .increase in pressure altitude means less thrust or more correctly less asymmetric thrust the controlling speed reduces as the thrust reduces exemple 333 Vmca decreases with increasing pressure altitude.Vmca decreases with increasing pressure altitude.
