The CR-4 is comparable to Jeppesen CR-2 computer. Made with PVC Plastic 4-1/4" Diameter
The CR Computer has been a favourite of professional pilots, navigators, and flight engineers for approximately 20 years. If you began your flying career with the basic E6-B type computer you will find both similarities and important differences between the E6-B and the CR Computers.
Once you become familiar with the CR computer it will more than likely be your favourite cockpit aid. Many of the scales on the calculator side are similar to those found on the E6-B. However, the CR has several new functions not available on other computers, making it the most useful instrument for modern piloting needs. The wind computation uses a wind triangle that is somewhat different that the E6-B and provides quick, simplified solutions to all course navigation problems.
We offer three models of the CR computer, all with the same functionality.
The CR-3 is sized for pocket convenience. The CR-4 is purchased by the U.S. Military (NSN 1R 6605-00-928-4552 UX). The larger CR-6 provides maximum readability.
Only APR's computer have exclusive APR Microset that allows them to be aligned for total accuracy before leaving our factory.
The calculator side of the CR computer is designed for quick, accurate computation with problem solving capabilities adapted to current aviation needs.
The wind-computing side applies the latest "state-of-the-art" technology. With this new instrument your pre-flight and in-flight calculations are easier and more accurate.
Although they are precision instruments you will take pride in owning, the information they give you is only as good as the information you give them. For this reason we recommend you take the time to carefully study the comprehensive instruction manual that come with each of our CR units.
E6-B2 D with High Speed Wind Slide of 100 to 800 ks or miles. Compressibility "F" Factor Scale shows the "F" Correction Factors for TAS. Gives Calibrated Airspeed from 200 to 550 Knots at Pressure Altitudes of 10,000 to 50,000 feet. Crosswind grid shows method to calculate crosswind and headwind components. Anodized Aluminum Computer, 4-7/8" x 11-1/8"
The E6-B features easy to read lettering, a wind component grid and comprehensive crosswind correction chart, and on the flip slide, computes time, speed, distance, altitude, true airspeed, and density altitude problems as well as conversions. Nautical and statute scales, and instructions are included. Embodies all the requirements for UK PPL exams. Measures 245 x 120mm.
This pocket-sized, brushed aluminum E6-B is a full-function aviation computer. Popular among military pilots, it features a high-speed and low-speed wind correction slide, high-speed compressibility table, vinyl case, and instruction manual. Micro E6-B performs all the standard manual flight computer functions, and it conveniently fits in a shirt pocket or glove box. 6" x 3-1/2".
Regolo tascabile in plastica
This useful tool shows a pilot which entry is appropriate given the assigned holding radial, making it a superb learning tool.
Approved for use during FAA Knowledge Exams!
The Holding Pattern Visualizer is approved for use during FAA Knowledge Exams!
You are flying a heading of 360 when you are issued this clearance “…hold east of the ABC VORTAC on the zero niner zero radial, right turns…”
This clearance is enough to invoke a rapid heart beat in the most experienced pilots. Although holding patterns may be used on any instrument flight, holding clearances are issued infrequently enough for pilots to get a little rusty on the procedures. Visualizing a holding pattern from a current position is one of the more challenging aspects of instrument flight.
ASA’s holding pattern computer shows pilots which entry is appropriate given the assigned holding radial. The design not only displays the appropriate entry procedure for both standard and nonstandard patterns (direct, parallel, or teardrop), but also depicts how pilots get to this entry, given their current aircraft heading.
Holding pattern practice is now part of the instrument currency requirements (every 6 months, instrument-rated pilots must execute 6 instrument approaches and practice intercepting and tracking a NAVAID, as well as holding procedures). This handy pocket-sized tool may be used as a refresher on the ground, as well as a quick-reference guide in flight.
A perfect learning tool for experienced instrument pilots, students, and convenient instructional aid for flight instructors. Made from durable plastic in the USA.
