How do you prevent an aircraft reaching Mcrit?
How do you prevent an aircraft reaching Mcrit?
Decreasing speed, by reducing engine power or pitching up.
What can you tell about occluded fronts?
What can you tell about occluded fronts?
Occluded fronts are formed during the process of cyclogenesis when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface.
Occluded fronts usually form around mature low pressure areas.
What effect does a wet runway have on V1?
What effect does a wet runway have on V1?
V1 is lower when the runway is wet than when the runway is dry, because of the longer ASDR on a wet runway.

What is N1, N2, EGT and EPR?
What is N1, N2, EGT and EPR?
N1= Low pressure compressor spool or fan rotation speed. Usually expressed as a % of Max N1.
N2= High pressure compressor rotation speed.
EGT= Exhaust gas temperature, indicates the temperature at the first stage of the turbine, which is the most critical temperature in the engine.
EPR= Engine pressure ratio of the inlet to the jet pipe, displayed on the EPR gauge to use as a parameter for setting engine thrust
What is convergency?
What is convergency?
Meridians converge from their maximum distance apart (at the equator) to the poles where they meet.
Great circles are the shortest distance between two points and convergency represents the change in direction experienced between those points.
How much thrust comes from the N1 fan?
How much thrust comes from the N1 fan?
Depends on the engine.
In the case of the 737-800 CFM56, 27,300lbs total thrust at a ratio of 5.5:1
What setting would you set the trim to for long range cruise?
What setting would you set the trim to for long range cruise?
Nose up
What are fusible plugs, where are they used, how do they work, why do we have them?
What are fusible plugs, where are they used, how do they work, why do we have them?
Fusible plugs offer protection from tire blowouts caused by thermal expansion that is generated in the tire under extra hard braking conditions.
What is a wing tip?
What is a wing tip?
A wing tip is the part of the wing that is the most distant from the fuselage of a fixed-wing aircraft.
