Question 99-1 : What will increase the 'landing field length limited landing mass' when operating with the anti skid inoperative ? [ Diploma registration ]
A headwind.
Ecqb04, october 2017...if you have a weight limitation at landing due to the length of the runway, a headwind will help you to have a reduced approach and landing speed, therefore you may land at a higher mass..other statements will are wrong since theay lead to an increase in the required landing distance and therefore a decrease in the 'landing field length limited landing mass'.
Question 99-2 : When calculating approach speeds, the minimum approach speed in the initial approach phase is usually ?
1.4 to 1.5 times vs1.
Question 99-3 : You are approaching a wet runway in gusty conditions, you should ?
Increase approach speed.
Ecqb04, october 2017...you should, in order to avoid windshear, increase slightly your approach speed... but you must land at your calculated landing speed, not less, not more...
Question 99-4 : Compared with a level runway, the use of a runway with a 2% downslope will ?
Reduce vmbe.
Ecqb04, october 2017...vmbe maximum brake energy speed is the speed from which the aeroplane may be brought to a stop without exceeding the maximum energy absorption capability of the brakes. for a downhill slope, you will reach vmbe at a lower speed compared to a level runway more kinetic energy needs to be absorb due to the down hill component of the runway..also, a downhill slope means that you need a longer distance to stop in case of failure before v1, and you will reach v1 at an earlier point in the take off run than on a 'flat' runway. v1 has to be reduced..vmbe and v1 will be reduced.
Question 99-5 : If the anti skid system is inoperative, may auto brake system can be used ?
No, never.
.anti skid system protection is provided during auto brake operation, therefore, if anti skid is inoperative you can not use the auto brake system.
Question 99-6 : You climb with a climb speed schedule 300/.78. what do you expect in the crossover altitude 29200 ft oat = isa ?
The rate of climb increases since the constant ias climb is replaced by the constant mach climb.
Question 99-7 : The effect of an aft cg on take off performance are ?
Take off distance decreases, climb gradient increases.
Ecqb04, october 2017.
Question 99-8 : At maximum landing mass, the structure of the aircraft is designed for a rate of descent of ?
600 ft/min.
Question 99-9 : The approach climb requirement is normally met by ?

Question 99-10 : A change of runway in use from a runway slope of 1% downhill to a runway slope of 1% uphill will ?
Increase take off run, increase take off distance.
Question 99-11 : An uphill slope runway will ?
Increase asdr.
Ecqb04, october 2017...a uphill slope increases the accelerate stop distance required asdr. taking off on a uphill slope does decrease the braking distance in the case of a rejected take off, but it increases the distance taken to accelerate to v1 due to the addition of the uphill component of the weight of the aircraft decreasing the rate of acceleration.
Question 99-12 : Runway 30 is in use and the threshold elevation is 2139 feet, threshold elevation of runway 12 is 2289 feet..take off run available is 1720 metres and clearway is 280 metres..what is the slope of the runway in use ?
2.65% uphill.
.2289 ft 2139 ft = 150 ft...150 ft x 0.3048 = 45,72m...runway lenght is 1720m, slope in % is. 45,72m /1720m x 100 = 2.65%.
Question 99-13 : In the event of an engine failure during cruise, it is necessary to reduce speed and descend to lower altitude at speed ?
For maximum lift/drag ratio and, if necessary, start fuel jettisoning.
Ecqb04, october 2017

Question 99-20 : Changing flaps selection from 10° to flaps 0° while establish in climb after take off, will have the following effects ?

Question 99-36 : The effect an increase of weight has on the value of stalling speed las is that vs ?
Increases.
.stall speed of an aircraft changes in proportion to the square root of the change in mass...for example, if an aeroplane has a stall speed of 78 kt at its mass of 5000 kg. the stall speed when the mass is 6850 kg will be.change in mass ratio = new mass / old mass = 6850/5000 = 1.37..square root of 1.37 = 1.17.original stall speed = 78 kt.stall speed for a weight of 6850 kg ==> 78 x 1.17 = 91 kt...vs increases for an increase of weight. stall will occur earlier.

108 kt.
.on short final you are supposed to be at 1.3 x vs.
Question 99-38 : In twin engine aeroplanes with propellers turning clockwise as seen from behind ?
The left engine is the critical engine.
Clockwise rotation as viewed from the pilot's seat, the critical engine will be the left engine. /com en/com080 341.jpg.multi engine aeroplanes are subject to p factor just as single engine aeroplanes are. the descending propeller blade of each engine will produce greater thrust than the ascending blade when the aeroplane is operated under power and at positive angles of attack. the descending propeller blade of the right engine is also a greater distance from the center of gravity, and therefore has a longer moment arm than the descending propeller blade of the left engine. as a result, failure of the left engine will result in the most asymmetrical thrust adverse yaw as the right engine will be providing the remaining thrust.
Question 99-39 : The parameters taken into account for take off performance calculations are ?
Question 99-40 : Unless otherwise specified in the afm, for a performance class b aeroplane landing on a dry, short grass runway, what factor must be applied to the landing distance ?
1.15
Cap 698 – landing class b..a the landing distance, from a screen height of 50 ft, must not exceed 70% of the landing distance available, i.e. a factor of 1.43...b if the landing surface is grass up to 20 cm long on firm soil, the landing distance should be multiplied by a factor of 1.15...c if the metar or taf or combination of both indicate that the runway may be wet at the estimated time of arrival, the landing distance should be multiplied by a factor of 1.15...d the landing distance should be increased by 5% for each 1% downslope. no allowance is permitted for upslope...e the despatch rules for scheduled planned landing calculations are in jar ops 1.550 c.
