What can you tell about adiabatic lapse rates?
What can you tell about adiabatic lapse rates?
When considering a volume of air, adiabatic lapse rate is the temperature change that is caused by the vertical movement of the volume, andThe Lapse Rate is the rate at which temperature changes with height in the atmosphere.
The Environmental Lapse Rate (ELR) is according to ISA 2°C per 1000 feet increasing altitude.
For unsaturated air, the lapse rate is 3°C per 1000 feet, this is called the Dry Adiabatic Lapse Rate (DALR).
The Saturated Adiabatic Lapse Rate (SALR) is the rate at which saturated air cools with height and is, at low levels and latitudes, 1.8°C per 1000 feet.
What systems protect against a stall?
What systems protect against a stall?
Stall warning, stick shaker, stick pusher, etc...
Generically we can destinguish between systems that alert the pilot of the impeding stall, like stall the stall warning or stick shaker, and systems that try to correct the situation, like a stick pusher.
Does the Boeing 737 have a critical engine?
Does the Boeing 737 have a critical engine?
No, there is no P-factor (asymmetric blade effect) as on a propeller-driven aircraft.
If you only have a compass, which is easier to navigate along: a line of longitude or a line of latitude?
If you only have a compass, which is easier to navigate along: a line of longitude or a line of latitude?
A line of latitude.
Is the landing gear in the Seneca electrically or hydraulically operated?
Is the landing gear in the Seneca electrically or hydraulically operated?
We are missing the answer.
You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
No because it is warmer, according to ISA temperature should be -55°C
If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?
If you are flying your light twin, how would you ensure minimum obstacle clearance if your engine fails on take off? How would you do this, or, where can you find the relevant information?
In the airplane documents, as the airplane is certificated regarding performance to be able to fly blue line speed (or Vyse) in this situation, so I would climb at this speed to ensure minimum obstacle clearance.
What are the dangers of flying into thunderstorms?
What are the dangers of flying into thunderstorms?
Dangers of flying into thunderstorms:
Severe wind shear and turbulence (with a risk of structural problems, loss of altitude, loss of airspeed) Severe icing Hail Lightning strikes (with a risk of damage to electrical systems) Radio Communications and Navigation interference from static electricity in thunderstorms
Can you go through DA or MDA?
Can you go through DA or MDA?
You can go through a DA, but not a MDA.
A Decision Height, used in precision approaches, defines the point where a go around should be performed. It accounts for the altitude loss during the initial seconds of the go around maneuver.
The MDA does not account for this and assumes the pilot will never go below this altitude. When performing a CDFA most operators establish a Derived Decision altitude (DDA) to account for the extra lost altitude.
Is the tropopause uniform in height? If not, what height is it at the pole and the equator?
Is the tropopause uniform in height? If not, what height is it at the pole and the equator?
No, tropopause at the pole is lower (30.000ft) than at the equator (56.000ft)
