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?

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:

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