A line of latitude.
Where is thrust produced in a gas turbine engine?
Where is thrust produced in a gas turbine engine?
Mostly in the fan, but also from the exhaust nozzle duct.
If you have a fire from the engine in the Warrior, what do you do?
If you have a fire from the engine in the Warrior, what do you do?
On the Warrior, I would perform the following items:
throttle closed mixture closed fuel selector off fuel pump off magnetos off (mayday + 7700 if time permits) and check if fire is out heater defrost off batt alt switches off top door latch unlatch seat belts erect secure and make a forced landing
What is profile drag?
What is profile drag?
Profile drag, also known as pressure drag or form drag, is the drag caused by the separation of the boundary layer from a surface and the wake created by that separation.
It is primarily dependent upon the shape of the object and increases directly with speed as the faster an aircraft moves the more air molecules collide with it.
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 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.
How does anti-skid work?
How does anti-skid work?
Antiskid has a detection system that senses the moment a wheel stops rotating.
Once it senses that the wheel is not rotating, the antiskid system releases brake pressure. This allows the wheel to regain traction with the surface, so that break application can be resumed and prevents complete loss of controllability.
What are the benefits of a free turbine?
What are the benefits of a free turbine?
A free turbine is a turbine that is not directly connected to the compressor. This allows the compressor to rotate at a different speed than the turbine. Since the turbine speed is coupled with the propeller, this allows for the propeller to be maintained at a constant ideal speed.
Another advantage is that free turbine engines can be designed to be more compact than their single shaft counterparts
How does an altimeter work and which errors can an altimeter experience?
How does an altimeter work and which errors can an altimeter experience?
When an aircraft climbs, the static pressure in the instrument case decreases, which allows the enclosed capsule to expand.
This in turn moves the needle on the instrument to indicate a corresponding altitude.
During descent, the opposite function applies.
Altimeter errors can originate and vary from:
Instrument Pressure Time-lag Barometric Density Temperature Blocked static port
