(Refer to Figure 27.) An aircraft departs an airport in the eastern daylight time zone at 0945 EDT for a 2-hour flight to an airport located in the central daylight time zone. The landing should be at what coordinated universal time?

Answer: 1545Z.

First, convert the departure time from Eastern Daylight Time (EDT) to Coordinated Universal Time (UTC) by adding 4 hours (0945 EDT + 4 hours = 1345Z). Then, add the 2-hour flight duration to the UTC departure time. This results in a landing time of 1545Z (1345Z + 2 hours).

(Refer to Figure 27.) An aircraft departs an airport in the central standard time zone at 0930 CST for a 2-hour flight to an airport located in the mountain standard time zone. The landing should be at what time?

Answer: 1030 MST.

Convert the departure time from Central Standard Time (CST) to Coordinated Universal Time (UTC) by adding 6 hours (0930 CST + 6 hours = 1530Z). Add the 2-hour flight duration to get the UTC arrival time (1530Z + 2 hours = 1730Z). Finally, convert the UTC arrival time to Mountain Standard Time (MST) by subtracting 7 hours (1730Z - 7 hours = 1030 MST).

(Refer to Figure 27.) An aircraft departs an airport in the central standard time zone at 0845 CST for a 2-hour flight to an airport located in the mountain standard time zone. The landing should be at what coordinated universal time?

Answer: 1645Z.

First, convert the departure time from Central Standard Time (CST) to Coordinated Universal Time (UTC) by adding 6 hours (0845 CST + 6 hours = 1445Z). Then, add the 2-hour flight duration to the UTC departure time. This results in a landing time of 1645Z (1445Z + 2 hours).

(Refer to Figure 27.) An aircraft departs an airport in the mountain standard time zone at 1615 MST for a 2-hour 15-minute flight to an airport located in the Pacific standard time zone. The estimated time of arrival at the destination airport should be

Answer: 1730 PST.

Convert the departure time from Mountain Standard Time (MST) to Coordinated Universal Time (UTC) by adding 7 hours (1615 MST + 7 hours = 2315Z). Add the 2-hour 15-minute flight duration to get the UTC arrival time (2315Z + 2 hours 15 minutes = 0130Z the next day). Finally, convert the UTC arrival time to Pacific Standard Time (PST) by subtracting 8 hours (0130Z - 8 hours = 1730 PST).

(Refer to Figure 27.) An aircraft departs an airport in the Pacific standard time zone at 1030 PST for a 4-hour flight to an airport located in the central standard time zone. The landing should be at what coordinated universal time?

Answer: 2230Z.

First, convert the departure time from Pacific Standard Time (PST) to Coordinated Universal Time (UTC) by adding 8 hours (1030 PST + 8 hours = 1830Z). Then, add the 4-hour flight duration to the UTC departure time. This results in a landing time of 2230Z (1830Z + 4 hours).

(Refer to Figure 27.) An aircraft departs an airport in the mountain standard time zone at 1515 MST for a 2-hour 30-minute flight to an airport located in the Pacific standard time zone. What is the estimated time of arrival at the destination airport?

Answer: 1645 PST.

To find the estimated time of arrival (ETA), first add the flight time to the departure time in MST: 1515 MST + 2 hours 30 minutes = 1745 MST. Next, convert the arrival time from Mountain Standard Time (MST) to Pacific Standard Time (PST). PST is one hour behind MST, so subtract one hour from 1745 MST, resulting in an ETA of 1645 PST.

(Refer to Figure 20, area 5.) The CAUTION box denotes what hazard to aircraft?

Answer: Unmarked balloon on cable to 3,008 feet MSL.

Referring to Figure 20, area 5, the CAUTION box explicitly states 'UNMARKED BALLOON ON CABLE TO 3008 MSL'. This text directly identifies the hazard. Therefore, the caution box denotes an unmarked balloon attached to a cable, extending up to 3,008 feet Mean Sea Level (MSL), which poses a potential collision risk to aircraft.

(Refer to Figure 20, area 2.) The flag symbol at Lake Drummond represents a

Answer: visual checkpoint used to identify position for initial callup to Norfolk Approach Control.

On a VFR sectional chart, a flag symbol, such as the one at Lake Drummond in Figure 20, area 2, indicates a VFR visual checkpoint. These checkpoints are designated geographical locations that pilots use to identify their position. They are particularly useful for making initial radio contact with Air Traffic Control (ATC), especially when preparing to enter controlled airspace like Norfolk Class C.

(See Figure 52.) Your engine has started to run rough after leaving KLHM (Area 4) in a westbound direction. A landing at Van Dyke Airport

Answer: can be done in an emergency.

While private airports, often marked with 'PVT' on sectional charts like Van Dyke Airport in Figure 52, generally require prior permission for landing, Federal Aviation Regulations (FARs) allow for deviations in emergency situations. In an emergency, a pilot is permitted to land at any suitable location, including a private airport, to ensure the safety of the flight and its occupants. Therefore, an emergency landing is permissible.

Please see Figure 53. In the airport information box for the MADERA (MAE) airport north of area 2, what does the star next to the letter "L" denote?

Answer: Lighting limitations exist.

In the airport information box for MADERA (MAE) airport in Figure 53, the letter 'L' indicates the presence of airport lighting. A star next to the 'L' (L*) is a specific chart symbol denoting that lighting limitations exist at the airport. These limitations could include pilot-controlled lighting, part-time operations, or other restrictions on when and how the airport lights are available for use.

(See point 1 in Figure 53.) Near the Grupe (PVT) airport, the highest point on the land is

Answer: 9,400 feet MSL.

At point 1 in Figure 53, the large blue numbers '94' with a smaller '0' in the upper right corner of the quadrangle represent the Maximum Elevation Figure (MEF). The MEF indicates the highest obstacle or terrain feature within that specific quadrangle, expressed in hundreds of feet Mean Sea Level (MSL). Thus, '94' with a '0' signifies 9,400 feet MSL.

(See point 4 in Figure 52.) How far south of Lincoln Regional/Harder Airport (LHM) is the only impediment, and how high above the ground is it?

Answer: 296 feet.

Referring to Figure 52, point 4, locate the obstruction south of Lincoln Regional/Harder Airport (LHM). Obstacles on sectional charts are depicted with two numbers: the top number is the obstacle's height in feet Mean Sea Level (MSL), and the number in parentheses below it is its height in feet Above Ground Level (AGL). The question asks for the height above the ground, which is the AGL value of 296 feet.

(See point 4 in Figure 52.) How much higher than the airport elevation is the topography at the blockage, which is around 8 NM east southeast of Lincoln Airport?

Answer: 827 feet.

To determine how much higher the obstruction is than the airport elevation, first find the airport elevation for Lincoln Airport (LHM) from its information box, which is 1,177 feet MSL. Next, locate the obstruction 8 NM east-southeast of Lincoln Airport and identify its top elevation, which is 2,004 feet MSL. Subtract the airport elevation from the obstruction's MSL height: 2,004 feet MSL - 1,177 feet MSL = 827 feet.
