Learjet 25: This aircraft is capable of cruising at speeds of 500 miles an hour or greater in a no wind condition. It can cruise at altitudes much higher than most airliners do up to 45,000 ft. Some are capable of going all the way up to 51,000 ft while maintaining a cabin pressure of around 6,000 ft which is normal for most operations including air ambulance. The GE 610-6 turbojet engines are quite thirsty, consuming as much fuel at idle while on the ground as they do at 41,000 ft at 90 percent power. Therefore it is critical, especially when attempting a maximum range flight to arrive at the cruise altitude as quickly as possible. The range of this aircraft is anywhere from 2 hours and 30 minutes to 3 hours depending upon the particular wing design on that aircraft. Generally speaking a flight of 2 hours and 45 minutes will be a good estimate before a fuel stop is necessary. The Learjet 25 has been around for many years and has a proven safety record bar none. The engines are the most reliable and dependable of any engines in the industry today. The altitudes used mostly on this aircraft for best efficiency are easterly at 41,000 ft and westerly at 43,000 ft. Flights from the east coast to the west coast require two fuel stops. While going west to east requires only one fuel stop usually because of the prevailing winds from the west. Don't take my word for it though, nothing is constant in aviation!

Learjet 35: This aircraft is similar in speed and size as the Lear 25. There are some differences though. The cabin is a little longer, giving you more leg room. It also utilizes more fuel efficient engines (Garrett TFE 731 turbofan engines). The range will be between 4 hours to 4 hours and 30 minutes depending upon what kind of winds are being experienced, and or what modifications are on that particular aircraft. The Lear 35 has more power for taking off, but that power diminishes with altitude. Typically it flies in the mid to upper 30s. It can go higher, but normally a step climb has to be accomplished. Although the Lear 35 is more fuel efficient, the initial purchase price is higher, and the maintenance reserves on the engines more or less eliminates any real cost savings over the Lear 25 except for range. Drawbacks are: Most do not have a lavatory, and your bladder may not like the extra hour!! (Make sure to use the restroom before you leave)
