BGS post its - Perf Flashcards
When should reduced TO thrust normally not be used?
on contaminated rwys
when antiskid is not available
if windshear is reported in the TO flight path
reversers not operative
increased V2 procedure
What is V2?
TO safety speed
what order of speed in the flight plan lead to minimum fuel consumption?
Max RoC speed (Vy) up to cruise altitude
Max range speed for the cruise
descent at Vmd
what is density altitude used for?
determining the aeroplane performance
can autobrakes be used with the anti skid inop?
no
Who generally determines the contaminated runway performance for A/C?
the manufacturer
what is the comparision between Vx and Vy in the climb?
Vx is always lower than Vy
what is the Vmca requirement following a critical engine failure?
to maintain striaght flight
what happens to Vx and Vy with an increase in altitude?
the both decrease (not what was learnt)
What is cost index defined as?
costs incurred over time divided by fuel costs
what happens to power required for OEI class B aircraft compared to AEO?
it increases due to increase in total drag.
what may you be required to do to steepen a descent?
increase speed
for calculating ASDR, when is deceleration assumed to begin?
2 seconds after V1
(braking occuring at V1)
What documentation is for class A A/C?
CS-25
What documentation is for class B A/C?
CS-23
what can FLLTOM be limited by?
Vtyre
Vmbe
What is the RoC at te service ceiling?
a value above 0
what is the required minimum turn around time to avoid wheel brake plugs melting?
53 minutes
what manoeuvre limit is used for buffet onset boundary charts?
1.3g
What is the max operating altitude for an aircraft?
The maximum altitude an A/C can fly at due to the differential pressure between the cabin and the outside.
AKA pressurisation altitude
What should be assumed if only specific range is mentioned?
it is specific air range
What does ther increase V2 procedure do to CLTOM and RLTOM?
CLTOM increases
RLTOM stays the same
What is meant by a ‘downhill’ component of weight?
the component in the direction of drag in a climb
how many values of V1 are there for a balanced airfield at the FLLTOM?
1
