SriLankan Airbus A320 suffers multiple in-flight failures, declares emergency

Aerotime

With this system coming online, the aircraft’s autopilot and auto thrust systems disengaged as the systems could not agree on the true airspeed of the aircraft. They received a block clearance between 30,000ft and 35,000ft.

Air pressure and density

Professional Pilot

However, with no room to navigate up the steep glacial valley, the pilots finessed the airplane over the hurdle with no more than 200 ft of clearance. Every pilot knows that aircraft fly because the forces of lift and thrust balance or exceed the weight and drag countering them.

What Is Air Density? A Simple Guide for Pilots

Pilot Institute

These include lift, propeller thrust, and engine combustion. For example, if we were to takeoff on an airfield at sea level at 0C (32F), it would take 1520ft to reach our obstacle clearance height of 50ft. Whereas for the same airfield on a different day, if it were 30C (86F), that same obstacle clearance height would take 1880ft.

Danger lurks in circling approaches

Air Facts

For example, some aircraft limit flaps and gear in icing until on approach or forbid the use of speed brakes or require a minimum thrust setting. Particular attention to true airspeed vs. turn radius. If you depart MDA on the downwind or base leg, you’re on your own as far as obstacle clearance. No later than).

The rest is just lift, drag, thrust, weather, and navigation. What is your range and true airspeed? I rarely received an entire clearance when requesting IFR while en route. Of course, he had spent several hours in the Everglades waiting to be rescued from the alligators, so I was sympathetic. Oh, and some money.
