VFR requires a pilot to be able to see outside the cockpit to control the aircraft's altitude, navigate, and avoid obstacles and other aircraft. [3] Governing agencies establish specific requirements for VFR flight, including minimum visibility, and distance from clouds, to ensure that aircraft operating under VFR are visible from enough distance to ensure safety.
An altitude facility is much more complex than a sea level facility. The rocket is installed inside an enclosed chamber which is evacuated to a minimum pressure level before rocket firing. A typical chamber operating pressure of 0.16 psia (equivalent to an altitude of 100,000 feet) is established inside the chamber by some form of mechanical ...
ICAO Doc 4444 requires that radar systems should provide for the display of safety-related alerts including the presentation of minimum safe altitude warning. [2] The radar equipment predicts an aircraft’s position in 2 minutes based on present path of flight, and the controller issues a safety alert if the projected path encounters terrain or an obstruction.
ATC will assign altitudes in its initial clearance or amendments thereto, and navigational charts indicate minimum safe altitudes for airways. [ citation needed ] The approach portion of an IFR flight may begin with a standard terminal arrival route (STAR), describing common routes to fly to arrive at an initial approach fix (IAF) from which an ...

It also determined special aspects of aircraft performance such as stall speed (e.g., for single engine airplanes – not more than 61 knots), rate of climb (not less than 300 ft/min), take-off speed (not less than 1.2 x V S1), and weight of each pilot and passenger (170 lb for airplanes in the normal and commuter categories, and 190 lb for ...
The algorithms used may also provide in some systems a possible vectoring solution, that is, the manner in which to turn, descend, increase / decrease speed, or climb the aircraft in order to avoid infringing the minimum safety distance or altitude clearance. Minimum safe altitude warning (MSAW): a tool that alerts the controller if an aircraft ...
Above the TA, the aircraft altimeter pressure setting is changed to the standard pressure setting of 1013 hectopascals (equivalent to millibars) or 29.92 inches of mercury, with the aircraft altitude will be stated as a flight level instead of altitude. In the United States and Canada, the transition altitude is 18,000 ft (5,500 m). [5]
