An aircraft flying from A to B (total distance 110 NM) departed from A at 09:55 UTC. The planned arrival time at B is 10:35 UTC. After 25 minutes of flight, the aircraft overflies waypoint C located 65 NM away from A.

 What Ground Speed should be flown as from C in order to reach point B at the planned arrival time?

A chart has a scale of 1 inch = 20 NM. The distance between two points on the chart is 17 cm. Determine the Earth distance:

On a Direct Mercator chart, apart from meridians and the Equator, a great circle will be represented by a..

What is the True Airspeed TAS, given the following:

 Calibrated Airspeed CAS: 320 kt

 Pressure Altitude: 29000 ft

 Outside Air Temperature OAT: -45°C

 Compressibility Factor: 0.95

The chart convergency between two locations on a Lambert chart:

Calculate the constant of the cone for a Lambert chart with the parallel of origin at 30°N.

An aircraft is flying at FL080, where the Outside Air Temperature is ISA -7°C, with a CAS of 170 kt. Calculate the approximate TAS by applying the rule of thumb for TAS calculations.

An aircraft is planned to fly from position A to position B, distance 250 NM at an average GS of 115 kts. It departs A at 09:00 UTC. After flying 75 NM along track from A, the aircraft is 1.5 min behind planned time. Using the actual GS experienced, what is the revised ETA at B?

(For this question use to annex 061-12621A to 061-12638A). Which aeronautical chart symbol indicates a compulsory reporting point?

A straight line from A (53°N, 155°W) to B (53°N, 170°E) is drawn on a Lambert Conformal conical chart with standard parallels at 50°N and 56°N. When passing the meridian 175°E, the True Track is:
