An airspeed indicator is an aviation instrument which displays an aircraft's current airspeed.
A PITO tube is used to measure airspeed of the plane. The covers are put over the tubes when the aircraft is going to be on the ground for an extended period of time, and are removed before takeoff. They are there to prevent tube blockages, leading to airspeed failure, which (and it has happened) could mean a possible accident.
Sec. 91.117 - Aircraft speed.(a) Unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots (288 m.p.h.).(b) Unless otherwise authorized or required by ATC, no person may operate an aircraft at or below 2,500 feet above the surface within 4 nautical miles of the primary airport of a Class C or Class D airspace area at an indicated airspeed of more than 200 knots (230 mph.). This paragraph (b) does not apply to any operations within a Class B airspace area. Such operations shall comply with paragraph (a) of this section.
Critical speed in aviation refers to the airspeed at which an aircraft becomes aerodynamically efficient, typically associated with the onset of a stall. It is the speed below which the aircraft may not maintain controlled flight due to insufficient lift. Understanding critical speed is essential for pilots to ensure safe takeoff, landing, and maneuvering, as flying below this speed can lead to a loss of control. It varies based on aircraft design, weight, and environmental conditions.
Stall speed increases with altitude primarily due to the decrease in air density. As altitude rises, the thinner air provides less lift at a given airspeed, requiring an aircraft to fly faster to maintain the same level of lift and avoid stalling. Additionally, changes in aircraft performance characteristics at higher altitudes, such as engine power and control surface effectiveness, can further influence stall speed. Thus, pilots must adjust their flying techniques accordingly at higher elevations.
The airspeed indicator or airspeed gauge is an instrument used in an aircraft to display the airspeed in knots

An airspeed indicator is an aviation instrument which displays an aircraft's current airspeed.
Equivalent airspeed is speed at sea level in which the incompressible dynamic pressure can be produces as if it were at true airspeed. Equivalent airspeed is used to predict aircraft handling.
240-380 depending on the model, dc10's came in 2 different models with 2 subclasses for each model............hope this helps
Airspeed Ltd. was created in 1931.
Airspeed Aviation was created in 1986.

An airspeed is the speed at which an aircraft is travelling relative to the air through which it is flying.

City or highway mileage?
In an vertical climb it can only lose airspeed.
