What angle of attack do planes cruise at?
If we look at the midspan airfoil of the 737, this angle of attack is around 2.8 degree.
What is the cruising altitude of a 787?
43,000 Feet

What is the maximum altitude the b787 can fly on?
The 787 cabin is pressured to a maximum of 6,000 feet/1800 meter compared to as high as 8,000/2400 meter feet for other aircraft. Testing shows that passengers experience fewer headaches and less fatigue at 6,000 feet/1800 meter than at higher altitudes.
What’s the average landing speed of a B787-8?
The typical approach speed for a B787–8 landing at it’s maximum landing weight of 380,000lbs is 145kts (166mph)For the larger -9 it has an approach speed of 153kts (176mph) again at it’s max landing weight of 425,000lbs. Basically the heavier to aircraft the higher the speed required to make a safe…
What’s the cruise speed of a Boeing 787?
As well as bringing large jet ranges to a medium-sized jet, the Boeing 787 also matches the speeds of larger jets with a cruise of Mach 0.85. This is delivered with an environmentally friendly fuel saving in the area of 20% over similar-sized older airliners.
What is the wing angle of attack of a Boeing 737?
The B737-800WL (winglets) has an optimum Cruise Body Angle of 2.46 degrees Nose Up where the non-winglet version has optimum at 2.53 degrees. This attitude in cruise is associated with Long Range Cruise (LRC) for any given weight.
Which is the best angle of attack for takeoff?
The takeoff flight path that guarantees clearance of all obstacles ahead is calculated based on flight at these speeds. Following rotation at V R , V 2 is the resulting engine-out speed at an altitude of 35 ft and is usually slower than that for best lift-to-drag (L/D) ratio or angle of climb.
