How accurate are NDB's?

How accurate are NDB's?

NDB’s are stations emitting a signal. There is nothing for them to be accurate about. ADF's on the other hand, when tuned to an NDB need to be accurate within +/- 5 degrees.

To notify the crew of the aircraft of a particular position on the IAP.

Locators have been largely replaced with Distance Measuring Equipment (DME), but they can sometimes be found associated with Outer or Middle Markers where they are referred to as Locator Outer Marker (LOM) or Locator Middle Marker (LMM).

Why do some airplanes have dihedral wings?

Why do some airplanes have dihedral wings?

Dihedral provides:

Lateral stability (during a roll) Wing clearance, wingtip to ground has more space

How can you calculate Vref?

How can you calculate Vref?

Vref = 1.3 x Vs0 (stall speed in the landing configuration).

What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?

What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?

Asymmetric Committal Altitude/Height is the minimum height needed to establish a positive climb whilst maintaining adequate speed for control and removal of drag during an approach to a landing.

In the Seneca at Oxford we used 200ft AGL. At this altitude when continuing for landing you selected the landing flaps (check clear runway, on speed, on altitude, landing clearance received).

You now are committed to land, single engine G/A with flaps 40 and gear down is not possible in a Seneca.
